Executive summary

The 26 GHz band, being 24.25–27.5 GHz, is one of the bands at the forefront of the delivery of millimetre wave (mmWave1) fifth generation (5G) wireless broadband services globally. Completing the replanning of the 26 GHz band is a significant priority for the Australian Communications and Media Authority (ACMA) and important in providing certainty to stakeholders interested in this band.

This paper follows on from the options paper released in September 2018 and concludes the ACMA’s review of planning arrangements for the 26 GHz band. It is the culmination of a lengthy period of consultation, technical studies and engagement domestically and internationally on how best to facilitate the deployment of 5G wireless broadband services in the band.

The outcomes of those considerations are detailed in this paper. They include:

> The proposed introduction of wireless broadband services in the band, along with proposed coexistence conditions necessary to ensure the ongoing, protected use of the band by various incumbent fixed-satellite, space-research and passive-earth exploration satellite services.

> The identification of a suite of possible spectrum, apparatus and class licensing measures to facilitate a broad range of wireless broadband use cases.

The ACMA has formed the view that this combination of measures will best maximise the overall public benefit derived from use of the band.

Summary of ACMA considerations and conclusionsHighest value uses (HVU) of the band and the case for actionThe options paper contained a summary of the legislative and policy environment in which the ACMA determines how spectrum should be allocated. This included a description of the object of the Radiocommunications Act 1992, which sets out that management of the radiofrequency spectrum should be undertaken in order to (among other goals):> maximise—by ensuring the efficient allocation and use of the spectrum—the

overall public benefit derived from using the radiofrequency spectrum> provide a responsive and flexible approach to meeting the needs of spectrum users> encourage the use of efficient radiocommunication technologies so that a wide

range of services of an adequate quality can be provided> support the communications policy objectives of the Commonwealth Government.

The decisions and undertakings set out in this paper are consistent with those goals. Specifically, regarding the latter goal, enabling access to the band by wireless broadband services falls in line with a number of key policy objectives, including:

> promoting sharing through accommodation of a range of co-frequency services> enhancing delivery of fast broadband services> promoting the efficient use of spectrum through optimising its use

1 mmWaves span 30 to 300 GHz (i.e. a wavelength of 1 cm to 1 mm), however, in the current 5G context, mmWave bands in consideration span from around 24 GHz up to 86 GHz.

> fostering competitive telecommunications markets by providing alternative delivery mechanisms for ultra-fast broadband.

The options proposed in the previous paper were analysed against each of the principles for spectrum management. It was found that, at a high level, the introduction of wireless broadband services in the 26 GHz band would represent the band’s highest value use (HVU), pending considerations around coexistence between incumbent and prospective uses which were ongoing at the time.

Having since been satisfied that this coexistence is feasible, it follows that the overall public benefit can be further enhanced by maximising the amount of wireless broadband spectrum available—in both frequency and geographic area. This can be facilitated without compromising protection of existing uses that may continue in the band.

Coexistence of terrestrial wireless broadband with other servicesConsiderable discussion has focused internationally under the 2019 World Radiocommunication Conference (WRC-19) study process, and domestically through both the options paper and under the auspices of an ACMA-convened domestic working group, on issues related to coexistence between new wireless broadband and incumbent satellite services in the band. Specifically, this is related to the protection of:

> nearby passive earth exploration satellite services (passive EESS) operating in the range 23.6–24 GHz

> co-frequency space research service (SRS) earth receive stations at Tidbinbilla (ACT) and New Norcia (WA) operating in the range 25.5–27 GHz

> co-frequency fixed satellite service uplinks (FSS Earth-to-space) operating in the range 27–27.5 GHz.

Studies undertaken by Task Group 5/1 of the International Telecommunications Union Radiocommunications Sector (ITU-R) have shown that coexistence between wireless broadband and incumbent services will be achievable.

The ACMA takes the view that protection of each of these services must be assured before any decisions on allocation for wireless broadband can be made. The options paper identified ‘preferred’ options that were contingent on the resolution of coexistence conditions important to finalising the planning boundaries for the band and the amount of spectrum that can be made available.

Lower boundary Regarding coexistence with passive EESS, outcomes of international and domestic studies have led the ACMA to conclude that a guard band is needed between the lower edge of the 26 GHz band (24.25 GHz) and wide-area deployments authorised under spectrum licences.

For that reason, the ACMA proposes that the lowest edge of the band that should be made available for spectrum licensing will be from 25.1 GHz. However, access under apparatus and class licensing within this guard band (24.25–25.1 GHz) will still be permitted, with additional licence conditions to maintain protection of passive EESS. (Studies considered in the ACMA-convened domestic working group have shown that apparatus licensing will be possible down to 24.7 GHz.)

Upper boundaryIn the 27–27.5 GHz segment, international studies undertaken by Task Group 5/1 of the ITU-R have shown that space-based FSS receivers can be protected from wide-area wireless broadband deployments with a considerable margin. However, the assumptions underpinning these studies are generalised and do not completely reflect specific FSS deployment scenarios such as those in Australia. In particular, NBN Co operates gateway uplinks from a number of sites across Australia with some parameters different than assumed in those studies.

The ACMA has taken into account these differences in its own analysis, reaching a view that coexistence remains feasible by a smaller, yet still significant margin. However, NBN remains concerned that there is still a risk of interference to their satellites due to the statistical nature of studies and that actual wireless broadband deployments may vary from the assumed use which informed the parameters in the studies. To mitigate this risk, NBN Co has proposed licence conditions be imposed on licences in the 27–27.5 GHz band in areas surrounding their gateway earth stations that would preclude mobile wireless broadband but permit fixed use.

Given mmWave wireless broadband is a new technology, sharing studies have to rely on informed predictions of a future wireless broadband environment. In particular, device numbers and densities can only be based on ‘informed assumptions’, and while these assumptions necessarily err on the conservative side, there is a need to understand and mitigate potential drift from these assumptions in real-life network deployments.

The ACMA continues to hold the view that internationally-agreed assumptions used in Task Group 5/1 studies should be used in modelling wireless broadband characteristics given that Australia, in general, endeavours to enacts regulatory arrangements that align with international equipment standards. However, noting incumbent concerns, the ACMA considers it prudent to propose additional licence conditions for any wireless broadband licences that may be issued in the future in NBN gateway footprint areas in the frequency range 27–27.5 GHz.

These additional conditions are intended to promote confidence in coexistence by acting as a safeguard against any significant divergence from the wireless broadband models studied. This ensures that the protection being afforded to NBN gateway uplinks won’t be compromised by a significant divergence between study assumptions and actual wide-area wireless broadband deployments.

Supporting different types of wireless broadband uses through licensing options The options paper identified three broad categories of potential wireless broadband use:> type 1—traditional subscriber-based wide-area mobile or fixed network operator

deployments> type 2—smaller market/local subscriber-based networks> type 3— uncoordinated ad hoc deployments within the confines of private premises

or property.

The ACMA sought feedback about the appropriateness of different combinations of geographic areas, frequency ranges and licence types to best facilitate access for use cases that achieved coexistence with other uses of the band.

The ACMA concludes that the combination of spectrum, apparatus and class licences is the best way to facilitate access to the band for the three wireless broadband user types. The guard band to protect passive EESS with respect to spectrum licensed frequencies is proposed to extend to 25.1 GHz, which means that spectrum in the

acma | 3

24.25–25.1 GHz guard band may be used for apparatus and class licensing arrangements better optimised for types 2 and 3 uses.

No immediate demand emerged from consultations to warrant the implementation of class licensing on a co-frequency basis with proposed spectrum licensed segments. However, the ACMA sees value in retaining this flexibility for innovative uses of the spectrum that may emerge over time, so the ACMA is considering:

> Adding the frequency range 24.25–25.1 GHz to the Radiocommunications (Low Interference Potential Devices) Class Licence 2015 (LIPD class licence) to enable type 3 services, should additional demand emerge. This would be limited to indoor use only between 24.25 and 24.7 GHz to protect passive EESS operating in 23.6–24 GHz.

> Engaging further with equipment manufacturers and industry operators to provide further opportunity to ascertain potential demand. Should demand exceed the proposed 850 MHz (450 MHz indoor only, 400 MHz indoor/outdoor) use, the ACMA may consider expanding class licensing arrangements into the spectrum-licensed segment above 25.1 GHz. Any further extension of the proposed class licensing arrangements will preferably be finalised prior to any decision by the Minister for Communications to reallocate that segment for spectrum licensing.

These combined measures, if implemented, will segment the band into apparatus and spectrum licenced frequency ranges (with the boundary between the two at 25.1 GHz), with the addition of some lower-frequency class licensing.

This proposal would see 2.4 GHz (25.1–27.5 GHz) being made available for spectrum licensing for provision of type 1 services.

ACMA planning decisions and preliminary views Pursuant to the ACMA’s powers under the Radiocommunications Act 1992, the necessary steps to implement the planning decisions presented in this paper (and outlined above) take the form of a suite of planning decisions, intentions and preliminary views. These include decisions that must be made by the ACMA Authority in exercise of its statutory powers to progress apparatus and class licensing aspects of these planning decisions and making recommendations, as appropriate, to the Minister for Communications towards implementing the spectrum licence aspects. Ultimately, if the ACMA and the minister make the relevant decisions, this combination of measures could result in the following band structure (also depicted in Figure 1):> 24.25–24.7 GHz—class licensed access for wireless broadband limited to private

property (including domestic, industrial, business, commercial and government) and restricted to indoor use only (Australia-wide)

> 24.7–25.1 GHz—apparatus licensing, potentially using a new ‘spectrum-space’ apparatus licence type 2 and co-frequency class licensing (indoor and outdoor use) limited to private property (including domestic, industrial, business, commercial and government) for wireless broadband (Australia-wide)

> 25.1–27 GHz—spectrum licensing for wide-area wireless broadband in metropolitan areas and large regional centres (referred to as defined areas in this paper). Apparatus licensing (potentially using a new spectrum-space apparatus licence type) for wireless broadband elsewhere. Existing SRS earth stations in the range 25.5–27 GHz will be able to continue to operate with proposed licence conditions included on new wireless broadband licences to ensure coexistence.3 New SRS earth stations (if any) may also be permitted on a first-in-time

coordinated basis outside of defined areas (note that ‘defined areas’ pertains to areas potentially subject to spectrum licensing)

> 27–27.5 GHz—as for the 25.1–27 GHz band but with additional proposed licence conditions applied to wireless broadband licences within NBN satellite gateway uplink footprints. Existing FSS earth stations can continue to operate in the band. New FSS earth stations may also be permitted on a first-in-time coordinated basis outside of defined areas (note that ‘defined areas’ pertains to areas potentially subject to spectrum licensing).

Defined areasDefined areas available for wide-area spectrum licensing will align with areas where type 1 users are expected to deploy wireless broadband services. Based on submissions to the options paper, the ACMA has formed the preliminary view that defined areas should consist of towns/cities with a population over 50,000 as well as smaller towns/cities which, due to them being either holiday locations or having university campuses, are expected to require the deployment of high-density wireless broadband services.

As detailed in Figure 1, wireless broadband services will be authorised by apparatus licences outside of defined areas.

Next stepsTo give effect to the decisions and preliminary views outlined above, the ACMA will:> Consult on proposed amendments to the LIPD class licence to include new

arrangements for wireless broadband in 24.25–25.1 GHz (limited to indoors in the 24.25-24.7 GHz).

> Continue to work with non-traditional users of spectrum to identify potential spectrum requirements to facilitate future type 3 use, and consider the case of expanding class licensing into the 25.1–27.5 GHz range.

> Consult on the implementation of apparatus licensing arrangements in the 24.7–27.5 GHz range (with 25.1–27.5 GHz limited to outside of defined areas intended to be spectrum licensed).

> Commence work on spectrum licensing the 25.1–27.5 GHz band within defined areas. This will include consultation on a draft reallocation recommendation to the Minster in accordance with section 153G of the Act.

Following this consultation, and subject to any additional information obtained, the ACMA may make a reallocation recommendation to the minister in accordance with section 153F of the Act. If the minister decides to make a re-allocation declaration under section 153B of the Act, the ACMA will commence work to progress allocation of spectrum licences in those areas subject to re-allocation. This will include establishing a Technical Liaison Group (TLG) for the development of the technical framework for 26 GHz spectrum licences and consulting on the allocation process, including the allocation rules and marketing plan.

Introduction In September 2018, the ACMA released an options paper for wireless broadband services in the frequency range 24.25–27.5 GHz, known as the ‘26 GHz band’. That paper provided significant detail on drivers for wireless broadband access to the band, international studies and trends, technical issues—including coexistence studies with incumbent users—where these considerations sit with respect to the legislative and policy environment, and most critically, the planning options. Much of that information has not been reproduced in this paper, so this should be read in conjunction with the options paper.

The purpose of this paper is to communicate planning decisions and preliminary views that have been taken following consideration of responses to the options paper.

The options were presented as a range of potential combinations of what could be allocated—in terms of specific frequencies and areas—and how the band could be allocated, in terms of which licence types might be adopted in the band to meet a range of wireless broadband use cases.

A set of options were identified, comprising:

> frequency options—allocating either the 24.254–27 GHz or 24.254–27.5 GHz band, subject to coexistence potential between wireless broadband and fixed satellite service (FSS) uplinks in the 27–27.5 GHz range

> area options—‘defined areas’ for spectrum licensing, which would comprise either major metropolitan areas only, or metropolitan areas and regional centres, noting that regardless of spectrum licence area definition, wireless broadband services will be permitted access outside those areas through apparatus licensing

> licensing options—various combinations of spectrum, apparatus and class licensing options within the defined geographical areas to facilitate access for a number of different potential deployment models.

A series of questions were asked around the suitability of the proposed options, as well as the appetite for potential non-traditional wireless broadband use cases that might make a case for some of the more complex licensing models.

A three-type model was proposed to describe different categories of use:

> type 1—wide-area wireless broadband deployments traditionally undertaken by mobile network operators (MNOs) or some fixed telecommunication carriers

> type 2—smaller, local area market subscriber services such as those provided by wireless internet service providers (WISPs) or dedicated (e.g. government only) wireless broadband networks

> type 3—private, localised deployments within private property.

While all three use types might be authorised under any licence type, the presented options loosely aligned type 1, 2 and 3 uses as being authorised by spectrum, apparatus and class licenses respectively.

It was also noted that the bottom frequency edge of the 26 GHz band was not yet settled. 24.25 GHz was identified as ‘nominally’ the lower edge of the band, subject to further consideration of coexistence potential with passive Earth exploration satellite services (passive EESS) operating in the range 23.6–24 GHz. At the time of writing that paper, the Electronic Communication Committee of CEPT (ECC) had recently released a decision on emission limits for wireless broadband services operating in the

4 At the time of writing, the lower edge of the band available for wide-area licensing was still an open question. The starting assumption was at 24.25 GHz, however it was acknowledged that this frequency would likely be higher following completion of relevant coexistence studies.

26 GHz band to protect passive EESS. The ACMA subsequently established a working group5 to consider the implications of this decision and other considerations to ensure that any allocation for wireless broadband in Australia would protect passive EESS.

Concurrently, the ACMA has been considering future planning arrangements for the adjacent 28 GHz band. This band has a range of incumbent uses (including satellite and point-to-point services) and has significant international interest for wireless broadband use. The 28 GHz spectrum planning discussion paper was released in September 2018 and closed for consultation on 23 November 2018.

While planning of the 26 GHz band is more advanced than the 28 GHz band, there is a clear interrelationship between the two bands. The planning decisions communicated in this paper have been taken with that interrelationship in mind and subsequent consideration of 28 GHz planning options will take account of 26 GHz planning decisions.

Legislative and policy environment The options paper released in September 2018 contains a detailed breakdown of the policy and legislative environment in which the ACMA operates in considering the allocation of spectrum for wireless broadband services. This included descriptions of:

> the primary legislation under which the ACMA currently manages spectrum, being the Radiocommunications Act 1992 (the Act)

> the current review of that legislation being undertaken by the Department of Communications and the Arts (DoCA)6, noting that consideration of wireless broadband in the 26 GHz band is being undertaken under the umbrella of the current legislative environment

> the principles for spectrum management, which provide guidance when making decisions on spectrum allocation

> the three licence types under which spectrum access can be authorised, being apparatus, spectrum and class licensing

> key ACMA tools which provide transparency to industry and the public on spectrum management and allocation programs, including:

> the mobile broadband (MBB) strategy, which provides a framework for the consideration and, where deemed appropriate, progression of frequency bands to allocation for provision of mobile (and other wireless) broadband services

> the Five-year spectrum outlook (FYSO), which sets out the ACMA’s forward work program over a five-year period.

Given the relatively short period since the options paper was released, very little has changed in this environment, with the exception of the status of 26 GHz planning under the MBB strategy, which is detailed later in this paper.

Responses to the options paperThe options paper proposed a number of combinations of primary licensing options (options 2, 3, 4 and 5; option 1 is the default ‘no change’ option) and spectrum/defined area variants (variants a, b, c and d; note that ‘defined area’ pertains to areas potentially subject to spectrum licensing). The options are reproduced in Table 1 (refer to the options paper for detailed descriptions).

Summary of submissionsConsultation on the 26 GHz options paper closed 9 November 2018. Nineteen submissions7 were received from a range of sectors:> Mobile broadband sector: Responses were received from the Australian Mobile

Telecommunications Association (AMTA), Ericsson, Nokia, Optus, Qualcomm, Telstra and Vodafone. Key themes arising from these respondents included:> Support option 2d (spectrum licensing only in defined areas, which include

large regional centres, all the way up to 27.5 GHz) from the options paper, with expanded geographical areas to include additional regional centres.

> The frequency range 24.7–27.5 GHz should be spectrum licensed in metro areas and regional population centres.

> Apparatus licensing should not be available in the above spectrum space, however apparatus licences should be available in this spectrum outside defined areas.

> Spectrum below 24.7 GHz could be used for apparatus and/or class licensed access.

> No underlay class licence should be made in the range 24.7–27.5 GHz due to concerns about managing interference between type 1 and type 3 users and a lack of demand for type 3 services.

> Wireless broadband can coexist with satellite services in the 27–27.5 GHz range.

> Support out-of-band emission limits in the passive services band in the range -32 to -34 dBW/200 MHz for base stations and -28 to -31 dBW/200 MHz for user equipment.

> Fixed wireless broadband sector: Responses were received from Cambium Networks, NBN Co and WISPAU. The key theme of these responses was support for licensing arrangements suited for fixed broadband networks. Cambium Networks and WISPAU generally supported segmentation of the band to accommodate both spectrum and apparatus licensing and suggested that dynamic spectrum access arrangements should be considered. Cambium Networks indicated a preference for option 3, while WISPAU supported option 5, which would incorporate co-frequency class licensing for type 3 services. NBN Co indicated a preference for option 2d (with some additional licence conditions to protect satellite services).

> Satellite communications sector: Responses were received from Communications Alliance’s Satellite Spectrum Working Group (SSWG), IPSTAR, NBN Co, Optus and Viasat. Key themes from these responses included:> Consideration of planning arrangements in the 26 and 28 GHz bands should

not be made in isolation. It was also suggested by some responders that there should be no allocations to mobile broadband in the 28 GHz band as it would not be able to coexist with ubiquitous satellite earth stations, including very-small aperture terminals (VSATs) and Earth stations in motion (ESIMs).

> There was broad concern (other than from Optus) that mobile broadband may not be able to coexist with FSS uplinks in the range 27–27.5 GHz due to ITU-R sharing studies not considering likely 5G deployment characteristics.

> NBN Co, which operates gateway uplinks in the band, was particularly concerned, submitting its own study on coexistence that showed different outcomes than the studies undertaken by ITU-R and the ACMA.

> Of the satellite sector responders who provided a view on the upper limit of a wireless broadband allocation, all (other than NBN Co and Optus) indicated a preference of 27 GHz being the upper boundary. NBN Co and Optus both preferred an upper boundary of 27.5 GHz. There was also general support for the implementation of licence conditions and/or coordination zones to protect satellite services if a wireless broadband allocation is made above 27 GHz. NBN Co was particularly concerned about this point and provided example wireless broadband deployment restrictions to be applied within 250km of their gateway earth stations.

> NBN Co (which also operates fixed wireless broadband services) was of the view that coexistence between FSS and fixed broadband services would be viable.

> Science sector: Responses were received from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the European Space Agency (ESA). The key themes of these responses were that earth stations operating in the space research service (SRS) in the range 25.5–27 GHz at Tidbinbilla and New Norcia would need to be protected from wireless broadband services, as would passive EESS services operating in the 23.6–24 GHz range.

Responses were also received from Airbus, the Australian Competition and Consumer Commission (ACCC), the Department of Defence and Facebook. These responses included the following views:

> Airbus indicated support for arrangements for type 3 uses.> ACCC supported the ACMA’s approach to accelerate the band to the ‘preliminary

replanning’ stage.

10 | acma

> The Department of Defence took the view that spectrum licensing should be restricted to areas where ubiquitous mobile broadband services are likely to be deployed to ensure that spectrum is not denied to other potential licensees.

> Facebook suggested that there may be other future-use cases, such as High Altitude Platform Stations (HAPS), and therefore specific details on spectrum sharing should be deferred until the specifics of deployments are better known.

All submissions are available on the ACMA website.

Suggestions made in submissions, particularly those pertaining to allocation options and potential operating conditions, have been considered as part of the ACMA’s planning process—see ACMA planning decisions and preliminary views for more a detailed discussion of those considerations.

The mobile broadband sector’s view that spectrum licensing down to 24.7 GHz could feasibly protect passive EESS was based on a less stringent out-of-band emission limit than the ACMA contemplated in the options paper and therefore does not accord with the ACMA’s own studies (as presented to the domestic working group on 26 GHz coexistence).

NBN Co contributed a study of its own on coexistence between wireless broadband and their own FSS gateway uplinks operating in the range 27–27.5 GHz (and above). This contribution was submitted both to the working group on coexistence and in NBN Co’s response to the options paper. It challenged aspects of the parameters, methodology and conclusions of the work undertaken by the ACMA, both domestically and internationally. Additional commentary on coexistence between wireless broadband services and NBN Co’s gateway uplinks is provided in Annex C.

Some broader ACMA observations on submissions were:

> The ACMA agrees that planning decisions in the 26 and 28 GHz bands should not be taken independently of one another.

> Some submissions indicated a preference for an allocation for type 3 use. There was no indication of the demand for type 3 services, although it is acknowledged that type 3 users are not generally represented within the pool of traditional respondents to these consultation processes.

> There is general acknowledgement that a guard band greater than the default 250 MHz (24–24.25 GHz) would be needed between passive EESS and wide-area licensed wireless broadband. While there were differing views on how large the guard band should be, there is general agreement that part of that guard band might still be usable for some non-wide area (e.g. apparatus licensed or class licenced) services. The ACMA has included this in its considerations while maintaining the default position that passive EESS services must be protected.

ACMA planning decisions and preliminary viewsHighest value use (HVU) of the bandWhen determining whether to undertake spectrum re-farming, the ACMA considers the relative incremental benefits and costs of each re-farming option, and the option which features the highest net benefit is considered the highest value use of the band.

In the 26 GHz band, the ACMA is satisfied that the introduction of wireless broadband services under all options considered in the options paper can be achieved with no practical impact on the current operations of incumbent licensees. As such, the incremental costs from the proposed reforms are almost zero.

Having been satisfied that coexistence between incumbent and prospective uses can be achieved, the key question is which option provides for the highest incremental benefits. The differences among the options put forward in the options paper were based on differences in the licensing approaches used across varying frequencies and geographic regions. This analysis is described in detail in the options paper.

In order to facilitate the highest value uses of the band, the ACMA proposes:

> price-based allocation of spectrum licences for regions of Australia that feature the highest demand, which in this case is the most densely populated regions (price-based allocations ensure the highest value users are able to gain access to the spectrum)

> apparatus licensing in non-defined areas (i.e. regional areas)> apparatus licensing between 24.7 and 25.1 GHz Australia-wide> class licensing between 24.25 and 25.1 GHz, limited to indoor use only in the

range 24.25–24.7 GHz.

The ACMA considers that this mix of spectrum, apparatus and class licensing provides not only for the protection of incumbent users, but also provides for the appropriate mix of potential wireless broadband network types.

Use casesA key theme of the options paper was the scope for multiple authorisation regimes, considering both the increased potential for sharing afforded by 5G technology and mmWave propagation characteristics, and the amount of spectrum available in the 26 GHz band. A combination of the three licence types available was proposed to optimise and accommodate a range of potential use types, as distinct from more traditional wide-area spectrum licence-only approaches to wireless broadband spectrum releases.

Responses to the options paper showed clear interest in accessing the 26 GHz band for wireless broadband services by both type 1 wide-area mobile and fixed broadband sectors users, and type 2 smaller, local-area broadband providers. While type 1 and 2 use types might be authorised under any of the three categories of licence, these two types of uses lend themselves to spectrum and apparatus licensing approaches respectively.

While minimal direct interest was expressed in the potential type 3 access option, the ACMA’s experience is that these types of users do not always contribute to consultation processes, or more importantly, may not yet be engaged in identifying potential opportunities that might be afforded by 5G wireless broadband.

While the ACMA intends to pursue class licensing in part of the 26 GHz band, it does not see an immediate appetite for a class licence to be applied co-frequency with spectrum licences in defined areas. However, noting that there remains a potential for additional demand for this type of access to materialise later, the ACMA wants to ensure that there are contingencies in place to cater for this. We will retain scope for expanding type 3 use through:

> proposed amendment to the LIPD class licence to implement class licensing in the passive EESS guard band frequencies below those available for spectrum licensing (totalling 850 MHz of spectrum—see below discussion on frequency ranges)

> a commitment to continue to monitor demand and developments in this sector, and potentially expand the frequency range of the abovementioned class licence into the spectrum licensed band.

Any decision to enact this expansion would preferably be communicated prior to the finalisation of arrangements for any spectrum licence allocation.

Coexistence of wireless broadband and incumbent servicesProtection of passive EESS operating in the range 23.6–24 GHzThe guard band between passive EESS and high-density outdoor wireless broadband services will necessarily be greater than the default 250 MHz of 24–24.25 GHz. This is due to a need to limit the level of unwanted out-of-band emissions from wireless broadband services into the adjacent passive EESS band.

Using the conservative emission limits set down by CEPT’s ECC8 (with adjustments commensurate with the lower expected deployment density and interference environment in Australia), the ACMA proposes that wireless broadband total radiated power (TRP) limits of -37 dBW/200 MHz for base stations and -33 dBW/200 MHz for user equipment (UE) into the frequency range 23.6–24 GHz9 will be applied. These limits have been based on the those set down by the ECC, but have been adjusted to account for:> lower population densities in Australian cities compared to Europe> a lower risk of interference to the EESS (passive) from fixed services operating

below 23.6 GHz in Australia than in Europe, owing to an existing guard band between these services in Australia.

As a matter of practice, transmissions from the majority of wireless broadband devices will be lower power than the prescribed overall (in-band) TRP limits to allow for manufacturing tolerances and variations due to temperature and ageing, which will help further mitigate interference potential into passive EESS.10

Considering these proposed unwanted emission limits in conjunction with expected IMT filter rolloffs results in an assessment that high-density outdoor wireless broadband services will be able to be deployed down to 25.1 GHz while still protecting passive EESS, providing a reasonably conservative guard band of 1.1 GHz.

This is not to suggest that wireless broadband services cannot be deployed below 25.1 GHz, but unconstrained wide area services cannot adequately guarantee that

8 See ECC/DEC/(18)06.9 These limits are based on currently available information, noting that unwanted emission limits are expected to be included in the ITU-R Radio Regulations as an outcome of WRC-19.10 For example, a GSA contribution to the ECC (document ECC(18)035) discusses tolerances for manufacturing, ageing, and temperature variances. An example of the impact of manufacturing tolerances on filter characteristics can been seen in contribution RA-1712718 to 3GPP TSG-RAN WG4 meeting #85.

passive EESS can be protected to the targeted level equivalent to the European levels from aggregate out-of-band emissions. To manage aggregate out-of-band emission levels the ACMA proposes to put in place additional restrictions in the form of:> limitations on the number of outdoor base stations in the range 24.7–25.1 GHz

within a given area to limit aggregated out-of-band interference into the 23.6–24 GHz range

> restrict the use of the range 24.25–24.7 GHz to indoor only.

Protection of FSS uplinks operating in the range 27–27.5 GHzThe ACMA is satisfied that wireless broadband systems can coexist with Fixed Satellite Service (FSS) uplinks. To provide greater confidence and safeguards for coexistence of wireless broadband within NBN gateway footprint areas, additional licence conditions on wireless broadband services are being proposed. Additional commentary on coexistence between wireless broadband services and FSS uplinks is provided in Annex C.

The ACMA’s preliminary view is that the following additional licence conditions should apply to spectrum and apparatus licensed services in the range 27–27.5 GHz operating within NBN FSS gateway footprint areas (-3 dB contour) specified in Annex F:> outdoor base stations must have mechanical down tilt equal to or greater than 0°> outdoor base stations must not direct antenna beams (via electrical steering) to

elevation angles greater than 5° above the horizon for more than 5% of time > outdoor fixed UEs must not direct their antenna beam (via electrical steering) to

within 1.5° of the geostationary orbit (GSO) arc> reduced base station TRP limit of 25 dBm/200 MHz.

These additional conditions act as a safeguard to ensure that NBN gateway uplinks will be protected from the operation of wireless broadband deployments in that frequency segment. The effect of the conditions is to ensure that wireless broadband networks in these areas are designed and optimised to serve user equipment below the base station. It should be noted that power limitations are usually included in all spectrum licence technical frameworks.

A further condition that could be considered relates to limiting the number of outdoor base stations that can be deployed in any NBN gateway footprint area. Such a condition would provide a further layer of confidence that the input assumptions to sharing studies will not vary over time in a manner that materially impacts the conclusion of those studies. While the ACMA does not currently see a need for the application of this further condition, it may be considered at a later date.

Additional commentary on coexistence between wireless broadband services and FSS uplinks is provided in Annex C.

Coexistence and support for existing in-band class licensed servicesCurrent apparatus-licensed radiodetermination uses are generally limited to body scanning systems, which makes them largely confined to airport security screening areas and operating within shielded enclosures. These services occupy the entire 26 GHz band. Additionally, the LIPD class licence permits the operation of a number of short-range radars in parts of the band, including ultra-wideband (UWB) short-range vehicle radars operating in the frequency range 22–26.5 GHz. The options paper provided a rationale for why the ACMA sees no issue with coexistence between new wireless broadband services and incumbent radiodetermination services that operate across the entire 26 GHz band. This view has not changed.

14 | acma

Coexistence with current and possible new SRS earth stations Earth receive stations support space research activities and are currently restricted to a limited number of space communications facilities at New Norcia, WA, and Tidbinbilla, ACT.

The options paper suggested that interference potential from wireless broadband services could be mitigated through the implementation of coordination and/or exclusion zones around those sites. The ACMA proposes that exclusion zones in the form of HCIS areas (described in Annex E) be established to ensure ongoing protection of these two sites. In addition, the ACMA is proposing that all spectrum and apparatus licensed deployments must be coordinated with space research service receive sites specified in Annex E and protect to a level of -156 dBW/MHz11. These provisions will be codified into any new relevant apparatus and spectrum licence conditions.

Requests for additional Earth receive stations in the SRS will be considered on a case--by-case basis consistent with the intent of the arrangements outlined in this paper. This means that request for Earth receive station licences within spectrum licensed bands/areas would need to be considered in the context of an apparatus licence issued under subsection 105(2) of the Act (‘special circumstances’) provisions. Outside of those areas, protected Earth receive stations would be considered on a normal first-in-time, coordinated basis with wireless broadband services. Noting that both ESA and NASA have established sites, the ACMA expects there will be limited demand for further such sites.

Support for future FSS Earth stationsWireless broadband services will not be afforded any protection from existing transmitting FSS earth stations. New FSS earth stations will be permitted outside spectrum licensed defined areas, on a first-in-time coordinated basis with apparatus licensed wireless broadband services.

Wireless broadband licensing arrangementsThe key considerations in defining spectrum allocations for wireless broadband services is ensuring that provisions are suitable for the various user types and that wireless broadband services can coexist with incumbent space services. These two considerations are interrelated given that arrangements to protect incumbent services will affect how suitable the spectrum is for different use types.

Frequency segmentation of the bandThe need to protect incumbent satellite services requires additional restrictions to be applied on wireless broadband services. Unwanted emission limits in the range 23.6–24 GHz are proposed to be applied to all wireless broadband services throughout the 26 GHz band. Additional restrictions to protect satellite services are also required, however these do not need to be homogenously applied over the entire 26 GHz band. The additional measures are summarised below:> 24.25–25.1 GHz: Requires additional restrictions to protect passive EESS. Due to

practical filtering limitations these constraints will need to be more onerous at the lower end of this frequency range

> 25.1–27 GHz: No additional restrictions required> 27–27.5 GHz: Additional conditions proposed to safeguard NBN gateway uplinks.

Any additional restrictions will have a greater impact on high density wireless broadband deployments such as those expected to be deployed by type 1 users,

11 See Recommendation ITU-R SA.609-2.

acma | 15

compared with lower density deployments of type 2 and 3 users. The proposed conditions in 27–27.5 GHz are expected to have no or minimal impact on wireless broadband services. Therefore, the range 25.1–27.5 GHz should be optimised for type 1 use through the issue of spectrum licences in defined geographical areas.

This will provide a total of 2.4 GHz of spectrum (25.1–27.5 GHz) optimised for type 1 users in defined areas. Outside of defined areas, the range 25.1–27.5 GHz will be available for apparatus licensed wireless broadband services.

The ACMA considers that the additional restrictions required below 25.1 GHz will mean that this spectrum will be less suitable for type 1 users (that require densely arranged base stations). The ACMA notes also that there is 2.4 GHz of spectrum in metropolitan areas and regional centres that is being proposed for spectrum licensing—a significant quantum of spectrum—and the utility of the 24.7–25.1 GHz segment in the hands of type 1 users is likely to be small.

Alternatively, type 2 and 3 users may be able to utilise this spectrum for the provision of innovative 5G services. It is expected the 5G technologies appropriate for local deployment will facilitate access to a range of diverse vertical industries. Type 2 and 3 users may also require the flexibility to support a disparate set of location-specific business cases that do not align neatly with metro and regional centre boundaries or require only small areas within those boundaries.

The following arrangements will provide spectrum allocations for type 2 and 3 wireless broadband users while also ensuring coexistence with passive EESS:> In the range 24.7–25.1 GHz: Apparatus licensing available Australia-wide. The

ACMA proposes to adopt a policy, through an assignment instruction, to limit the number of base stations that may be assigned within a given area. This policy would limit aggregated out-of-band interference into the 23.6–24 GHz range (the proposed limits are set out in Table 2). On this basis, the ACMA considers apparatus licensing to be appropriate for this spectrum.

> Class licensing for devices operated on private property12 (with boundary power flux density (PFD) limits specified for coexistence with co-frequency apparatus licensed services). This will provide spectrum for type 3 users to deploy outdoor services.

> In the range 24.25–24.7 GHz: Class licensing for devices operated on private property limited to indoor use to ensure protection of passive EESS.

Geographical segmentationDefined areas available for wide-area spectrum licensing will include both large metro and regional centres. Submissions to the options paper indicated support for the defined regional areas to consist of towns/cities with a population over 50,000 as well as smaller towns/cities which, due to them being either holiday locations or having university campuses, are expected to require the deployment of high-density wireless broadband services. The ACMA agrees and has formed the preliminary view that these areas proposed in submissions should be subject to spectrum licensing and we have updated the defined areas accordingly. These areas are described in detail in Annex D.

In less densely populated regions (outside of the defined areas), it is expected that there will be less demand overall for 26 GHz spectrum. The ACMA will aim to facilitate all parties’ access to the spectrum using apparatus licensing. This is proposed to apply to all spectrum from 24.7–27.5 GHz. This approach is also consistent with the guiding principle that the spectrum be allocated to the highest value uses.

Planning decisions, intentions and preliminary viewsThis section summarises the ACMA’s views and proposals on how the 26 GHz band should be structured in terms of high-level frequency, geographic, coexistence and licensing arrangements for the introduction of wireless broadband services in the 26 GHz band.

The various arrangements for wireless broadband access described in earlier parts of this chapter are summarised at a high level in Figure 2.

The full suite of definitive licensing provisions and conditions is not included in this paper—this will be developed in due course under future consultation processes on relevant licensing frameworks and instructions, in accordance with normal practice. However, preliminary views on which licence conditions might be appropriate—particularly those conditions which are fundamental for coexistence with existing services—are included. It is noted that these issues have already been subject to extensive industry consultation.

Apparatus licensing with additional conditions to protect FSS uplinks – Australia-wide except defined areas. New FSS earth stations will also be permitted (except in defined areas) on a first-in-time coordinated basis with apparatus licensed wireless broadband services.

It is intended that the arrangements in Figure 2 will be implemented using a combination of both the various licensing tools at the ACMA’s disposal and exercising of Ministerial powers under the Radiocommunications Act 1992. The following text therefore contains a range of proposed decisions taken by the Authority, as well as intentions to take the necessary steps towards making the requisite recommendations to the minister to enable reallocation of parts of the band that are intended to be subject to spectrum licensing.

Planning decisionsThe ACMA proposes to:> Consult on adding 24.25–25.1 GHz to the Low Interference Potential Devices

(LIPD) Class Licence for the purposes of enabling uncoordinated time-division duplex (TDD) wireless broadband deployments. Class licence conditions are outlined below.

> Implement apparatus licensing arrangements, including creation of appropriate coordination instructions, for TDD wireless broadband services in the frequency range 24.7–27.5 GHz (outside of defined areas in the 25.1–27.5 GHz range).

IntentionsThe ACMA intends to commence work on spectrum licensing, including:> Consulting with existing licensees operating with frequency assignments in defined

areas and operating in the frequency range 25.1–27.5 GHz, prior to making any recommendation to the minister on reallocation of that range, in accordance with section 153G of the Act.

> Subject to consultation outcomes, recommend to the minister under section 153F of the Act that the 25.1–27.5 GHz frequency range be reallocated for spectrum licencing for wireless broadband services.

18 | acma

> Subject to the minister’s decision to make a reallocation declaration under section 153B of the Act, develop the technical framework (via the usual TLG process) and legislative instruments for the allocation of spectrum licences for wireless broadband services.

> If necessary, consider exercising the ACMA’s power under subsection 105(2) of the Act (‘special circumstances’) to take measures to allow continued apparatus licensing of specific incumbent radiodetermination services overlapping the range 25.1–27.5 GHz in areas to be subject to spectrum licensing.13

The ACMA intends to continue to work with non-traditional users such as retail/commercial facilities, academic institutions, hospitals, mine sites, government facilities, factories and other industrial plants to identify potential spectrum requirements to facilitate future type 3 use. If demand is projected to exceed the 850 MHz already agreed for class licensed wireless broadband services (24.25–25.1 GHz), the ACMA will consider expanding these arrangements into the segment identified for spectrum licensing (25.1–27.5 GHz). Any such consideration should preferably be finalised prior to a minister’s decision on reallocation of that segment for spectrum licensing.

Preliminary viewsThe ACMA has formed the following preliminary views on a range of provisions and conditions that might apply to class, apparatus and spectrum licences for wireless broadband services. Definitive conditions will be developed as part of standard consultative processes in the development of the relevant regulatory tools, including relevant legislative instruments. As such, the following should not be viewed as definitive views of the ACMA and all are subject to variation.

Class licence conditions—preliminary views:> Deployments may be fixed point-to-multipoint or mobile (base station with service

area) in nature. > Operation is permitted on an Australia-wide basis. > Service areas will be limited to private (including domestic, industrial, business,

commercial and government) property. This can be outdoors or indoors, depending on frequency range (see below).

> Services must not cause interference to, or claim protection from, other licensed services (including co-frequency apparatus-licensed services in the 24.7–25.1 GHz range).

> In the range 24.25-24.7 GHz, operation is limited to indoor use only.> In the range 24.7–25.1 GHz operation can be either indoors or outdoors.> Proposed conditions for indoor use:

> Base station total radiated power (TRP) is not to exceed 20 dBm/200 MHz.> User equipment TRP is not to exceed 22 dBm per occupied bandwidth. > Devices are to comply with the unwanted and spurious emission limits as

described in the 38 series of 3GPP specifications.14 > Proposed conditions for outdoor use (24.7–25.1 GHz only):

> Base station TRP is not to exceed 25 dBm/200 MHz. > User equipment TRP is not to exceed 22 dBm per occupied bandwidth.

13 It is likely that most of these existing licences are being be replaced with the Radiocommunications (Body Scanning—Aviation Security) Class Licence 2018, which would negate the need to exercise these measures.14 Building penetration loss (calculated using Recommendation ITU-R P.2109) is considered adequate to protect passive EESS from aggregate unwanted emissions from indoor wireless broadband services within the EESS footprint.

acma | 19

> The TRP is not to exceed -37 dBW/200 MHz for base stations and -33 dBW/200 MHz for UE, measured anywhere in the range 23.6–24 GHz. To meet these limits, it is likely that a combination of additional filtering and/or reduced transmit powers need to be utilised.

> Proposed conditions in the range 24.7–25.1 GHz:> The aggregate PFD is not to exceed -105.4 dBW/MHz/m2 at the property

boundary (measured outside in the case of indoor use to allow through-wall attenuation to be taken into account).15

Apparatus licence conditions—preliminary views:> Deployments may be fixed point-to-multipoint or mobile (base station with service

area) in nature. > Base station TRP is not to exceed 30 dBm/200 MHz.> User equipment TRP is not to exceed 22 dBm per occupied bandwidth. > Licence bandwidth not to exceed 100 MHz in the range 24.7–24.8 GHz, 150 MHz

in the range 24.8–25.1 GHz and 400 MHz in the range 25.1–27.5 GHz. > Authorisation may be under a potential new ‘spectrum-space’ area-based

apparatus licence type. The ACMA is exploring the design for this potential new licence type and considering relevant conditions. For example, boundary conditions such as PFD limits will need to be specified to ensure coexistence between adjacent service areas.

> Deployments must be coordinated with space research service receive sites specified in Annex E and not exceed -156 dBW/MHz at those sites.16

> Apparatus licences will be available Australia-wide, except in the defined areas specified in Annex D in the frequency range 25.1–27.5 GHz.

> Although apparatus licences may be issued with area boundaries overlapping the exclusion zones specified in Annex E, a licence condition is proposed to be included which specifies that no devices may be operated within the exclusion zones. All out-of-area conditions (other than those mandated for the protection of space research service receive sites detailed in Annex E) will apply at the outer HCIS boundary on the licence, even if this overlaps the exclusion zones. It is proposed that no licences will be issued that solely overlap the exclusion zones.

> To protect adjacent-band passive EESS, the following conditions will apply:> For outdoor devices operating at 25.1 GHz and above, the TRP is not to

exceed -37 dBW/200 MHz for base stations and -33 dBW/200 MHz for UE, measured anywhere in the range 23.6–24 GHz.

> Higher TRP levels in the range 23.6–24 GHz will be permissible for outdoor apparatus licensed devices operating below 25.1 GHz, owing to filtering being unable to provide enough attenuation at these frequency offsets to meet the limit specified above 25.1 GHz. These higher limits will be offset by limiting the number of devices within the passive EESS footprint to ensure that aggregate interference limits are not exceeded. TRP limits and device numbers applicable for outdoor wireless broadband services in the range 24.7–25.1 GHz are detailed in Table 2.

15 This aggregate PFD limit is based on providing a co-frequency apparatus-licensed service providing coverage up to the (other side of the) property boundary with an expectation of at least a 99% probability that the I/N from the class licenced device(s) into their service will not exceed -6 dB. It was derived via a statistical simulation using parameters from ITU-R Working Group TG 5/1 and no TDD-synchronisation between class and apparatus licensed services. Worst-case orientation of both class-licensed and adjacent area apparatus-licensed BS antenna arrays relative to one another was assumed. 16 Refer to Recommendation ITU-R SA.609 Protection criteria for radiocommunications links for manned and unmanned near-Earth research satellites and ITU-R SA.509-3 Space research earth station and radio astronomy reference antenna radiation pattern for use in interference calculations, including coordination procedures, for frequencies less than 30 GHz for SRS receiving station protection requirements and antenna characteristics.

20 | acma

> It is proposed that the ACMA will generally apply outdoor base station number limits specified in Table 2 when considering registrations for new outdoor base stations under an apparatus licence, on a first-come, first-served basis. For example, a prospective base station assignment in the range 24.7–24.8 GHz would only be made if there were fewer than 13 base stations already assigned within this frequency range within 9 km of the proposed new base station location.

> Indoor devices are to comply with the unwanted and spurious emission limits as described in the 38 series of 3GPP specifications.17

> The following additional conditions will apply for services operating within NBN gateway footprint areas specified in Annex F:> Base station TRP is not to exceed 25 dBm/200 MHz. > Outdoor base stations must have mechanical down tilt equal to or greater

than 0°. > Outdoor base stations must not direct antenna beams (via electrical steering)

to elevation angles greater than 5° above the horizon for more than 5% of time.

> Outdoor fixed UEs must not direct their antenna beam (via electrical steering) to within 1.5° the GSO arc.

> Subject to further consideration, a cap on outdoor wireless broadband base stations in NBN gateway footprint areas may be included.

Annex A—Working group on 26 GHz inter-service coexistence: Terms of ReferenceThis annex contains the Terms of Reference for the working group on 26 GHz inter-service coexistence.

Terms of ReferenceFunction  The working group work will consider technical coexistence matters at the edges of the 26 GHz band, specifically: 

> Lower frequency boundary of the 26 GHz band, having regard to coexistence with passive earth exploration satellite services (EESS). This work would consider possible Australian specific technical and licensing factors for facilitating coexistence with EESS (passive) compared to factors influencing international conclusions. 

> Upper frequency boundary of the 26 GHz band (specifically whether it should be 27 or 27.5 GHz), having regard to coexistence with FSS (earth to space). The group would also consider the necessity for (and if required, the nature of) possible domestic regulatory arrangements to facilitate coexistence between wireless broadband and FSS uplinks in the 27–27.5 GHz band (if the upper edge of the band was considered to be 27.5 GHz). 

Purpose 

The purpose of the working group is to inform stakeholder responses to the options paper on 26 GHz (specifically question 2), which will ultimately assist the Authority in its deliberations.  

Working methods and accountability  The working group will: 

> be chaired by the Executive Manager, Spectrum Planning and Engineering Branch, ACMA 

> form two sub-working groups (chaired by ACMA officers) to separately consider the upper and lower boundary questions 

> undertake its activities predominantly via correspondence, although physical meetings will be held as required. It is expected that two meetings will be held—first, to set up these two groups and second, to conclude the group’s work. 

The group’s deliberations should help inform individual stakeholder submissions on inter-service coexistence issues to the 26 GHz options paper. 

Membership 

Membership of the working group is open to all interested stakeholders, although attendance at physical meetings may need to be limited for capacity reasons.  

Nominations for membership should be forwarded to freqplan@acma.gov.au by COB 26 September 2018. 

24 | acma

Review The working group’s Terms of Reference will be considered and finalised at the first meeting.  

Working group cessation The working group will cease to operate after its report has been delivered on or before 24 October 2018,20 or as otherwise determined by the ACMA. This means the group will run concurrently with the consultation period for the options paper.  

20 This group was reconvened in January 2019 for by-correspondence consideration of possible licence conditions on wireless broadband services in the 27-27.5 GHz range.

Annex B—Working group on 26 GHz inter-service coexistence: Deliberation summaryWorking group overviewThe working group on 26 GHz inter-service coexistence was convened by the ACMA to accompany the consultation process on options for wireless broadband in that band. The intent was to help inform stakeholder input on some of the technical issues canvassed in the 26 GHz options paper.

A single meeting of the group was held, and a SharePoint site was set up to house relevant study material, as well as the group’s Terms of Reference. There were two sub-working groups; one to consider coexistence between wireless broadband and passive Earth exploration satellite services (EESS) operating in the range 23.6–24 GHz, and the other to consider the sensitivity of existing studies on coexistence between wireless broadband and fixed satellite services (FSS) in the range 27–27.5 GHz to parameter variability.

Discussions in both groups were primed by ACMA-drafted working documents which were intended to act as a starting point for the group’s work. A single meeting was held where the Terms of Reference were described and the two documents were introduced, along with a third paper contributed by NBN Co which is relevant to the work of sub-working group two. The remainder of the group’s work was undertaken by correspondence.

In January 2019, the ACMA re-convened the working group to discuss potential licence conditions for wireless broadband services in the range 27–27.5 GHz to provide additional certainty of coexistence with satellite uplinks. This work was undertaken via correspondence and ran for approximately four weeks, concluding mid-February 2019.

This annex summarises the group’s deliberations in both the meeting and correspondence work. A significant amount of material was received that will help inform ACMA staff recommendations towards decisions on the band’s configuration.

Sub-working group one—IMT/EESS coexistence workThis chapter provides a summary of responses to the EESS working paper. Responses were received from AMTA, the Bureau of Meteorology (BoM), Ericsson, and Optus. The ACMA appreciates the time and effort taken to produce these responses.

Responses have been grouped into themes and are summarised below.

Characteristics of EESS missionsThe working paper sought information on whether EESS emissions gather data in urban areas, and to ascertain the impact on data collected in other areas should protection requirements be exceeded in urban areas.

For the first question, both BoM and Optus noted that EESS data is collected over urban areas.

For the second question, BoM and Optus both indicated that the impact urban area interference would have on data collected in other areas will depend on the characteristics of the EESS satellite. BoM indicated that the amount of overlap between successive scans, and the sampling rate and integration time are influencing factors. Any overlap of an area where interference is received will contaminate data for an area twice the size of the instrument’s instantaneous field of view.

IMT-2020 densityThe working paper asked a series of questions about the estimated density of IMT-2020 deployments in Australia.

Ericsson suggested that deployment densities would not be significantly different to other developed cities. Optus indicated that since the Australian population and infrastructure densities are lower than in other countries, the results of ITU-R studies (i.e. maximum emissions in the passive band) should be scaled accordingly. Optus also indicated that the preliminary scaling of 2.7 dB in the working paper may be on the low side.

Optus also expressed the view that, due to lower infrastructure density in Australia, emission limits for base stations should be at the lower end of the African/Arab emission limit range (which is -32 to -37 dBW/200MHz for base stations). AMTA also agreed with this view.

BoM said that urban densities should be assumed over the entire EESS footprint. Ericsson suggested that densities will be dependent on use cases, and it is possible that in some cases suburban high-speed/low-latency deployments may require base station numbers which potentially exceed those for eMBB in urban areas.

In response to whether the ‘worst-case’ example of a footprint focused on Sydney CBD is appropriate, BoM suggested that moving the red circle (in Figure 1 of the EESS working paper) approximately 4km south—to only include built-up areas (and removing the harbour)—would represent the worst case. The ACMA notes that IMT numbers in Table 1 of the working paper are calculated using the entire area within the red circle, including areas of water. Therefore, estimated numbers in Table 1 will be the same as if the circle was relocated 4km south.

Optus suggested that the Sydney CBD is a good example of a worst-case analysis as it includes the peak urban density, and an Australian mix of urban and suburban areas within the EESS footprint.

BoM posed the question of how the ACMA will monitor IMT deployment numbers (particularly user terminal numbers), to ensure that actual deployments will comply with the assumptions used in the development of protection limits.

Apportionment of protection requirementThe European emission limits assume that the passive service protection requirement is equally shared between IMT-2020 and fixed services below 23.6 GHz. The working paper considered if this apportionment is necessary in Australia.

BoM said that domestic arrangements for fixed services appear to offer a higher level of protection to the EESS band than the channel arrangements in Europe. BoM also queried what assurances the ACMA can give that there will be no future changes to these arrangements that may increase unwanted emissions into the EESS band.

AMTA and Optus both indicated that apportionment of the protection requirement is not required, and that the ECC limit can be relaxed by 3dB.

Both BoM and Optus agree that the interference potential is likely to be higher from IMT-2020 than fixed services. This is owing to IMT-2020 having higher anticipated device numbers and higher emission limits above the horizon.

IMT-2020 filteringEricsson indicated that the filter response in Figure 2 of the working paper is an indication of what could realistically be achieved, noting that the transition region of the slope is dependent on the bandwidth and centre frequency of the filter. Ericsson also noted that LTCC filter technology provides similar performance, in particular the PCB filter from the working paper and the LTCC filter offered the most up-to-date results available, however work is still ongoing.

Ericsson indicated that manufacturing and temperature tolerances should be included when considering filter responses. Both AMTA, Ericsson and Optus indicated that tolerance margins should improve over time, however Ericsson noted that the production tolerances included in sensitivity analysis studies are already quite stringent.

Optus suggested that a guard band of 0.5 GHz is possible based on allocation work in the 24 GHz band currently being undertaken in the US, noting that their filtering requirements are easier to achieve due to the smaller bandwidth of 1 GHz. AMTA also agreed with this view.

Band licensing arrangementsEricsson indicated that dividing the band into class, apparatus and spectrum licensing segments is a practical compromise which will protect the passive band while offering long-term flexibility to the lower end of the 26 GHz band. Optus suggested that segmentation will introduce added complexity and spectrum inefficiency. Optus also argued that splitting equipment types may have detrimental effects on the availability of equipment at viable cost.

Both Ericsson and Optus viewed that a larger spectrum licence allocation, potentially with deployment constraints at the lower end, is preferable to a smaller allocation without constraints.

AMTA indicated support of ‘unconstrained’ deployments of IMT-2020 above 25.1 GHz. AMTA also noted that the working group should be focussed on the lower boundary for ‘unconstrained’ outdoor deployments, and that other allocation methods (class and/or apparatus licensed) are still an open issue under consideration in the options Paper.

Sub-working group two—IMT/FSS coexistence sensitivity analysisOverviewWorking group two was focussed on the coexistence studies between FSS uplinks and potential wireless broadband operating in the frequency range 27–27.5 GHz. The ACMA tabled a working paper that was intended to serve as an adjunct to existing international studies. The ACMA paper contained a sensitivity analysis which sought to identify how much variability of the assumptions underpinning those studies could be absorbed before (additional) constraints might need to be imposed on wireless broadband licences if they were to be issued in the 27–27.5 GHz segment.

28 | acma

The ACMA’s sensitivity analysis focused on four key parametric assumptions which might be considered susceptible to variations, being IMT device density, IMT device total radiated power (TRP), IMT device antenna configuration and satellite antenna configuration. The sensitivity analysis was based on a ‘pass’ margin of 32 dB below I/N which was based on the Australian input to TG-5/1. This was later revised to 27 dB when taking into account some NBN-specific antenna configurations which were raised during the working group’s single meeting.

The Terms of Reference specified that the intent was not to question the methods or assumptions contained in studies undertaken in TG-5/1, rather to examine the extent to which parameter variability might warrant consideration of licensing constraints to ensure the FSS E-s protection criteria would continue to be met.

NBN Co inputNBN contributed a separate sensitivity analysis that considered the effect on coexistence by varying numerous parameters used in the TG-5/1 studies (but still evaluated using the method contributed by Australia). This was done on the basis that the international studies were more generalised than the specific beam configurations of NBN satellites operating over Australia and therefore did not contain sufficient rigour for assessing coexistence within Australia.

The NBN Co view was that the interference scenario should not be considered to be ergodic, as interference into FSS uplink receivers could conceivably be dominated by a small number of wireless broadband terminals if there was a concurrence of ‘worse-case’ parameter values on those terminals. NBN Co was of the view that this concurrence was a realistic possibly and that actual wireless broadband deployments are likely to differ materially from the TG-5/1 studies.

NBN Co therefore proposed that the baseline study needed to be revisited to reflect their worst-case scenarios, so their alternative sensitivity analysis was preceded by a ‘rebaselining’ of the initial parameters. The result was that, when evaluated using these parameters, the implications for coexistence would not be as favourable and in fact would fail.

Summary of responsesThis section provides a summary of responses provided by working group members.

Optus noted the significant ‘pass’ margins of the TG-5/1 studies and that even a 20dB reduction of those margins would not affect the coexistence outcome. NBN Co’s follow-up reinforced the premises of their contribution to the working group but added that the ACMA’s update to the IMT/FSS sensitivity analysis working paper to take into account higher-gain NBN satellite antennas still did not reflect that satellite reception extends beyond its 3dB footprint. AMTA, in its response, questioned why NBN Co continued to make arguments on the basis of an issue the ACMA had (in their view) addressed in the update.

Otherwise, none of the inputs commented on the ACMA’s sensitivity analysis (either in support or to refute that analysis). Instead, the majority of responses contained commentary on NBN Co’s contribution.

Telstra disagreed that the TG-5/1 studies had failed to take account of an acceptable range of scenarios and questioned the ‘non-ergodic’ assertions that underpin NBN Co’s concerns, noting that the short-term, worst-case parametric assumptions that make up the rebaselined scenario approximates a deterministic rather than probabilistic analysis. Telstra and AMTA contested the worst-case nature of the

acma | 29

rebaselined parameter settings and Telstra expanding on this by questioning the providence of some of the individual parameter settings.

The ACMA also questioned why the aggregate interference under this (apparent) short-term scenario was not evaluated against less-stringent short-term criteria.

Potential licence conditions for IMT/FSS coexistenceIn January 2018, the ACMA re-convened the working group and asked for feedback and discussion on potential licence conditions to aid the coexistence of wireless broadband services and fixed satellite uplinks. This section provides an overview of the working group’s deliberations on this issue.

To commence discussion, NBN Co provided additional detail on the licence conditions it proposed in its submission to the options paper. In particular, NBN Co proposed that the following conditions be applied to wireless broadband licences within 250 km of its gateway earth stations:

> UE antenna boresight elevation not to exceed 5°. > UE antenna gain of at least 17 dBi. > BS antenna boresight elevation not to exceed 0°.

In addition, NBN Co suggested that a maximum BS deployment density limit, in addition to the above conditions, should apply to fixed broadband services. NBN Co was of the view that the BS density limit is not a reliable proxy for ensuring the interference contribution from UEs aligns with the scenarios studied. Based on these proposed conditions, NBN Co maintained its view that only fixed broadband services could be viably deployed in the range 27–27.5 GHz.

Telstra expressed the view that, based on existing domestic studies (which included Australia-specific characteristics) that resulted in large protection margins, wireless broadband services can coexist with fixed satellite services. Subsequently, Telstra saw no reason why additional licence conditions should be imposed on wireless broadband services.

Optus also supported Telstra’s view and said that BS densities are not a reliable proxy for the interference contribution from UEs. This is because such a limitation would not consider factors such as:

> the number of UEs and their activity factors> the base station deployment scenarios> the power level per active device.

In addition, Optus agreed with the results of existing international and domestic studies and said that the large margins indicated in these studies would accommodate any likely variation in study assumptions. Optus also suggested that it would be more appropriate to set an interference limit that wireless broadband services need to comply with, rather than implement licence conditions which limit network design characteristics.

The Bureau of Meteorology suggested that the same licence conditions proposed in the range 27-27.5 GHz could also be used to ensure coexistence between wireless broadband services and passive EESS in the 23.6-24 GHz band.

Annex C—Coexistence of wireless broadband with NBN satellite services A key issue identified in considering possible planning arrangements to support wireless broadband in the 26 GHz band has been the feasibility of coexistence of terrestrial wireless broadband with fixed satellite service uplinks (i.e. satellite receivers) in 27–27.5 GHz. NBN Co has been very active in these considerations given its use of 27-27.5 GHz for gateway satellite uplinks at 10 discrete locations for the SkyMuster satellite system.

In their submission to the options paper, NBN Co expressed the view that previous Australian and international studies, which concluded that wireless broadband and satellite uplinks could coexist, did not adequately account for the parameters of NBN Co’s existing high throughput satellite network or consider the full range of possible wireless broadband deployment scenarios. In support of this view, NBN Co provided an additional study21 which considered the impact that different input parameters will have on the potential coexistence of wireless broadband with satellite services.

That additional study concluded that inclusion of these NBN parameters would erode margins to the point where coexistence between wireless broadband and satellite services would not be possible, based on the study’s assumed input parameters. NBN Co proposed that technical licence conditions—which would preclude mobile (but not fixed) wireless broadband in the 27–27.5 GHz band in substantial areas around NBN Co satellite gateway sites—would need to be applied to ensure coexistence is achievable.

In November 2015, Study Group 5 of the ITU-R established a dedicated task group, TG 5/1, to conduct sharing and compatibility studies relevant to WRC-19 agenda item 1.13. This work included studies on coexistence between wireless broadband and FSS uplinks in the 26 GHz band.22 Of the 15 studies submitted for this issue, all except for one demonstrate that coexistence of wireless broadband and FSS would be possible.

In the US, the Federal Communications Commission (FCC) designated the frequency range 27.5–28.35 GHz on a primary basis for upper microwave flexible use service (UMFUS). UMFUS allows for flexible fixed and mobile commercial use of the band, which includes 5G wireless broadband technologies. This allocation has been made on a shared basis with FSS uplinks (high-throughput satellites characteristics where included in the consultation process23, although NBN-specific satellite characteristics where not explicitly considered). When considering the potential aggregate interference from wireless broadband services into satellite receivers, the FCC concluded that the risk of harmful interference is low and decided against the establishment of regulatory limits on aggregate wireless broadband power levels.24 While this allocation is in the adjacent 28 GHz band, the interference scenario is essentially the same as for the 26 GHz band.

21 Available at the ACMA website.22 See Attachment 3 of Annex 3 of document 5-1/478.23 For example, SES provided analysis using characteristics of its SES-15 satellite; see paragraph 289 of FCC-16-89A1.24 See FCC-16-89A1.

The sharing outcomes mooted by NBN Co were at odds with international study outcomes and coexistence arrangements being considered elsewhere. However, the ACMA conducted its own detailed review of that study in order to gain an assurance that identifying that frequency segment for wireless broadband would not compromise existing NBN services. In almost all cases the alternative parameters and scenarios proposed in that study were found to be very much in the ‘worst case’ category. In the ACMA’s view, the likelihood of a concurrence of those conditions occurring is considered a low probability. In conducting our own review of that input, it was impossible to recreate the NBN interference conclusions without using a scenario and set of operating parameters and conditions that could not reasonably be expected to be realised.

On the other hand, the impact of such an outcome occurring would be high, given the importance of SkyMuster services, so the risk profile is assessed as essentially being (very) low probability with a high impact.

This analysis supports the ACMA’s conclusion that additional licence conditions be applied to wireless broadband services in the relevant areas/frequency segments to act as a safeguard against the risk of interference. These conditions are not expected to materially limit wireless broadband deployments but will serve to provide a ceiling on any potential ‘creep’ over and above the expected interference environment.

Maximum power limits have historically always been specified on spectrum and apparatus licences and, as per normal practice, the ACMA will include these on wireless broadband licences across the entire 26 GHz band. However, to provide additional certainty that emissions above the horizon will not vary significantly from those assumed in studies, the ACMA has formed the preliminary view to include the following licence conditions on wireless broadband stations within a 3 dB NBN gateway footprint and in the range 27–27.5 GHz:

> Outdoor base stations must not direct antenna beams (via electrical steering) to elevation angles greater than 5° above the horizon for more than 5% of time.

> Outdoor base stations must have an antenna mechanical down tilt equal to or greater than 0°.

> Outdoor fixed UEs must not direct their main antenna beam within 1.5° of the GSO arc.

Furthermore, subject to further consideration, a cap on wireless broadband device deployments in NBN gateway footprint areas may provide an additional safeguard against a dramatic underestimation in assumed device densities.

These preliminary views on technical coexistence conditions regarding outdoor base stations and fixed UEs, and the possibility of a cap on wireless broadband deployment numbers, will be further explored as part the subsequent development of planning and licensing frameworks—such as Technical Liaison Groups (TLGs) in the case of spectrum licences.

Annex D—Description of defined areasThe ACMA has formed the preliminary view that the geographical areas in Table 4 and displayed in Figure 3 should be subject to spectrum licensing in the range 25.1–27.5 GHz. These areas consist of towns/cities with populations greater than 50,000, as well as smaller towns/cities which are either holiday locations or have university campuses. These areas align with those suggested in submissions to the options paper.

The Australian Spectrum Map Grid (ASMG) is used to define geographical areas over which spectrum licences are issued. The Hierarchical Cell Identification Scheme (HCIS) is a naming convention developed by the ACMA that applies unique ‘names’ to each of the cells that make up the ASMG. The ASMG and HCIS are described in detail in the document, The Australian spectrum map grid 2012.

The HCIS coordinates in Table 4 can be converted into a Placemark file (viewable in Google Earth) through a facility on the ACMA website.

Annex E—Protection of receiving earth stations operating in the SRS in the frequency range 25.5–27 GHzReceiving earth stations operating in the space research service (SRS) in the frequency range 25.5–27 GHz are to be protected from interference from co-frequency wireless broadband services. Locations of SRS earth stations are:

> New Norcia Deep Space Ground Station, lat -31.0484/long 116.1914 degrees

> Canberra Deep Space Communications Complex (Tidbinbilla), lat -35.3951/long 148.9785 degrees.

Coordination requirementsAll spectrum and apparatus licensed deployments are not to exceed an aggregate interference level of -156 dBW/MHz at the earth station, inclusive of the earth station antenna gain (see below). This requirement will apply to wireless broadband services outside the exclusion zones in Table 5. The following ITU-R Recommendations are relevant for coordination with SRS earth stations:

> Recommendation ITU-R SA.609 Protection criteria for radiocommunications links for manned and unmanned near-Earth research satellite

> ITU-R SA.509-3 Space research earth station and radio astronomy reference antenna radiation pattern for use in interference calculations, including coordination procedures, for frequencies less than 30 GHz.

Geographic exclusion zonesFurthermore, exclusion zones within the vicinity of the above sites shall apply to spectrum and apparatus licences in the range 25.5–27 GHz. It is proposed that a licence condition will be applied to affected apparatus and spectrum licences, which will specify that no devices are to be operated within the HCIS areas listed in Table 5—this will apply even if the licensed area overlaps the areas in Table 5. The areas in Table 5 will not be excised from apparatus and spectrum licences so that any out-of-area conditions (other than for the protection of space research service earth stations detailed in this annex) will apply at the outer boundary of the licence, even if this boundary overlaps an area in Table 5.

HCIS is a naming convention developed by the ACMA that applies unique ‘names’ to each of the cells that make up the Australian Spectrum Map Grid (ASMG)25. These HCIS cells can be converted into a Placemark file (viewable in Google Earth) through a facility on the ACMA website. Figures 4 and 5 show these zones on a map for Tidbinbilla and New Norcia respectively.

These zones are informed by an analysis of potential impact from wireless broadband on SRS receivers, taking into account a number of ‘worst case’ assumptions:

> Main-beam of wireless broadband base stations directed towards the receiving earth station.

> Antenna co-polarisation.

25 See The Australian spectrum map grid 2012.

> Earth station antenna horizontal pointing directly at wireless broadband base stations at minimum elevation angle (and resultant gain towards horizon as per ITU-R SA.509-3):> 11.3° for Tidbinbilla (minimum allowable above terrain obstruction in the

direction of nearby metropolitan areas)—results in an off-axis gain towards horizontal of 6dBi.

> 10° for New Norcia—results in an off-axis gain towards horizontal of 7 dBi.> Earth station antenna height of 19m (actual). > Wireless broadband base station antenna height of 30m (worst case). > Earth station sensitivity of -156 dBW/MHz. > Wireless broadband base station EIRP towards earth station of -3 dBW/MHz,

based on:> 64 element array, each element fed with 7 dBm/200 MHz → 25 dBm total

radiated power (TRP). > Worst case (highest possible) main-beam gain of 23 dBi. > Total worst case EIRP of 48 dBm/200 MHz, rounded up to 50 dBm to provide

additional assurance → -3 dBW/MHz.> ITU-R P.526 propagation model (diffraction) given the ‘worst case’ (and

therefore short-term incidence) nature of many of the assumptions used. Scenario was also modelled using Recommendation ITU-R P.452 for comparison (assuming 1 and 0.1% incidences) but results didn’t vary appreciably, given the frequency, power, distance and terrain factors involved.

Annex F—Areas subject to additional conditionsThe areas where additional constrains apply for wireless broadband services in the range 27–27.5 GHz are provided in Table 6. These areas are based on the 3 dB footprint of satellites at longitudes of 140°E and 145°E for beams pointed at each of the 10 NBN gateway earth stations.

Figures 6 and 7 show the 3 dB contours of NBN Co’s Geeveston and Waroona gateway footprints (noting that these are just the footprint ‘contours’ and not the HCIS cells listed in Table 6), overlaying some of the defined areas from Annex D. These are the only areas where additional conditions will apply to spectrum licences in the 27–27.5 GHz segment. Additional conditions will apply to apparatus licences in all other areas listed in Table 6 in that frequency segment.
