RSAC Paper 5/2003

BEIEFING ON MAIN DECISIONS OF WRC-03

Purpose

This paper briefs Members on the main decisions of the WorldRadiocommunication Conference (“WRC-03”) of InternationalTelecommunication Union (“ITU”) held on 9 June – 4 July 2003 inGeneva, Switzerland.

Agenda item 1.2

“to review and take action, as required, on No. 5.134 and relatedResolutions 517 (Rev.WRC-97) and 537 (WRC-97) and Recommendations515 (Rev.WRC-97), 517 (HFBC-87), 519 (WARC-92) and Appendix 11, inthe light of the studies and actions set out therein, having particularregard to the advancement of new modulation techniques, includingdigital techniques, capable of providing an optimum balance betweensound quality, bandwidth and circuit reliability in the use of the HF bandsallocated to the broadcasting service.”

2. ITU-R conducted studies concerning the use of digitalmodulation techniques in the HF bands and developed the servicerequirements, system characteristics and planning parameters for digitalbroadcasting at frequencies below 30 MHz.

WRC-03 Decision: Resolution 517 as revised by WRC-03 resolves thatthe early introduction of digitally modulated emissions as recommendedby the ITU-R in the HF bands between 5900 kHz and 26100 kHzallocated to the broadcasting service be encouraged. Relevantprovisions of the Radio Regulations (“RR”) have been updatedaccordingly.

Agenda item 1.3“to consider identification of globally/regionally harmonized bands, tothe extent practicable, for the implementation of future advanced

2

solutions to meet the needs of public protection agencies, including thosedealing with emergency situations and disaster relief, and to makeregulatory provisions, as necessary, taking into account Resolution 645(WRC-2000)”

3. Communication systems for Public Protection and DisasterRelief (“PPDR”) will base on the terrestrial mobile service and fixedservice. They will operate in an integrated manner to serve differentneeds in terms of functionality and geographic coverage for the PPDRapplications.

WRC-03 Decision: WRC-03 has identified the bands 406.1 – 430 MHz,440 – 470 MHz, 806 – 824/ 851 – 869 MHz, 4940 – 4990 MHz and5850 – 5925 MHz be used for PPDR in Region 3. Such use for PPDRfor global harmonization is given in Resolution [COM 5/4].

Agenda item 1.4“to consider the results of studies related to Resolution 114 (WRC-95),dealing with the use of the band 5091 – 5150 MHz by the fixed-satelliteservice (Earth-to-space) (limited to non-GSO MSS feeder links), andreview the allocations to the aeronautical radionavigation service and thefixed-satellite service in the band 5091 – 5150 MHz”

4. International Civil Aviation Organisation (“ICAO”) hasidentified the band 5091 – 5150 MHz, which is allocated to aeronauticalradionavigation service (“ARNS”) on a primary basis worldwide, forexpansion of Microwave Landing System (“MLS”) and Airport Networkand Location Equipment (“ANLE”) which is a high integrity LAN toprovide radionavigation and safety communications for the airport areas.This band was also allocated to NGSO mobile satellite service (“MSS”)feeder links under RR No. 5.444A for short-term developmentrequirements until 1 January 2008.

WRC-03 Decision: Resolution 114 as revised by WRC-03 resolves thatthe allocation to the aeronautical radionavigation service and the FSS inthe band 5091 – 5150 MHz be reviewed at a future competent conferenceprior to 2018. Respective deadlines as given in RR No. 5.444A havebeen updated accordingly.

Agenda item 1.5“to consider, in accordance with Resolution 736 (WRC-2000), regulatoryprovisions and spectrum requirements for new and additional allocationsto the mobile, fixed, Earth exploration-satellite and space researchservices, and to review the status of the radiolocation service in thefrequency range 5150 – 5725 MHz, with a view to upgrading it, takinginto account the results of ITU-R studies”

5. ITU-R Study Groups (“SGs”) had completed studies concerningspectrum requirements for Radio Local Area Network (“RLAN”), FixedWireless Access (“FWA”) in Region 3, Earth Exploration SatelliteService (“EESS”)/ Space Research Service (“SRS”) (active) and aconsequential review of the radiolocation service in the 5 GHz band.

Agenda item 1.6“to consider regulatory measures to protect feeder links (Earth-to-space)for the mobile-satellite service which operate in the band 5150 –5250 MHz, taking into account the latest ITU-R Recommendations (forexample, Recommendations ITU-R S.1426, ITU-R S.1427 andITU-R M.1454)”

6. For the protection of MSS feeder links, the power flux density(“pfd”) level of total RLAN interference observed at the victim satellitereceiver, for satellites using full earth coverage antennas, should be nogreater than the pfd levels specified in Recommendation ITU-R S.1426.ITU-R studies indicated that it was difficult to assess aggregateinterference at satellite receivers due to the proliferation of low poweredRLANs and to determine when pfd limits were reached.

WRC-03 Decision: WRC-03 has adopted the following co-primaryallocations in the 5 GHz band as a result of the discussions in agenda item1.5 and 1.6:

♦ Mobile Service in the bands 5150 – 5350 MHz and 5470 – 5725MHz for wireless access systems (“WAS”) including RLAN

♦ SRS (active) in the band 5350 – 5570 MHz♦ EESS (active) in the band 5460 – 5570 MHz♦ Radiolocation service in the band 5350 – 5650 MHz.

Resolution [COM5/16] gives the technical requirements for WASoperating in the 5 GHz band. The relevant provisions shallprovisionally apply as of 5 July 2003. WRC-03 also approved an

4

additional allocation in RR No. 5.BD01 for some Region 3 countriesincluding Australia, Korea and Japan for a co-primary allocation for fixedservice in the band 5250 – 5350 MHz for the implementation of fixedwireless access systems. Such use shall comply with RecommendationITU-R F.1613.

Agenda item 1.7“to consider issues concerning the amateur and amateur-satelliteservices”

7. WRC-03 reviewed the respective regulatory provisions for theamateur and amateur satellite service.

WRC-03 Decision: Article 25 for the amateur service has beenthoroughly reviewed. In particular, the mandatory requirement onMorse code test was lift to be determined by the respectiveadministrations. New provision has been added to allow the amateurs totransmit for third party only in case of emergency and disaster relief.The revised Article 25 would provisionally apply as of 5 July 2003.

Agenda Item 1.7.2“review of the provisions of Article 19 concerning the formation of callsigns in the amateur services in order to provide flexibility foradministrations”

8. RR No. 19.68 limited amateur and experimental call-signsuffixes to "a group of not more than three letters". This restrictionplaced a limit on the number of possible call-sign combinations.

WRC-03 Decision: The range of call signs was expanded by addition ofone character so that a group would now consist of not more fourcharacters, instead of three letters.

Agenda Item 1.7.3“review of the terms and definitions of Article 1 to the extent required asa consequence of changes made in Article 25”

5

9. Article 1 gives the terms and definitions for use in the RR.

WRC-03 Decision: No consequential changes to Article 1 was needed.

Agenda item 1.8.1“consideration of the results of studies regarding the boundary betweenspurious and out-of-band emissions, with a view to including theboundary in Appendix 3”

10. Appendix 3 defined spurious emissions as unwanted emissionswhich fell outside frequencies separated from the centre frequency of therelevant emission by more than 250 % of the necessary bandwidth of theemission. Since spurious emissions could occur anywhere outside thenecessary bandwidth of an emission, no boundary actually exists betweenout-of-band and spurious emissions. Recommendations ITU-R SM.329(spurious emissions) and SM.1541 (unwanted emissions in the out-of-band domain) included new definitions of the out-of-band and spurious“domains”.

WRC-03 Decision: Appendix 3 has been revised to include thetreatments for out-of-band and spurious domains.

Agenda item 1.8.2“consideration of the results of studies, and proposal of any regulatorymeasures regarding the protection of passive services from unwantedemissions, in particular from space service transmissions, in response torecommends 5 and 6 of Recommendation 66 (Rev.WRC-2000)”

11. Radio Astronomy Service (“RAS”), EESS, and SRS areparticularly susceptible to radio frequency interference because of theirhighly sensitive receivers to detect weak signals from the sky and spacesources. ITU-R SGs have developed methodology for analysingcompatibility between a passive service and an active service allocated indifferent bands and providing guidance on possible solutions.

WRC-03 Decision: Resolution [COM 4/14] as adopted by WRC-03concerning the compatibility analyses between the EESS (passive) andactive services resolves to recommend that WRC-07 review the results ofthe studies in order to consider regulatory measures, if appropriate, to

6

ensure the protection of the EESS (passive) service. WRC-03 has alsoadopted Resolution [COM 4/15] concerning compatibility between RASand the active space services in certain adjacent and nearby frequencybands.

Agenda item 1.9“to consider Appendix 13 and Resolution 331 (Rev.WRC-97) with a viewto their deletion and, if appropriate, to consider related changes toChapter SVII and other provisions of the Radio Regulations, as necessary,taking into account the continued transition to and introduction of theGlobal Maritime Distress and Safety System (GMDSS)”

12. Appendix 13 (Distress and Safety Communications (non-GlobalMaritime Distress Safety System (“GMDSS”) and Resolution 331 (Rev.WRC-97) concerned the transition to the GMDSS. There wasconsiderable number of maritime vessels yet to fit with the automatedcommunications systems. Moreover many administrations had also notyet required certain classes of non-SOLAS (Safety of Life at Sea) vesselsto fit with the new automated equipment.

WRC-03 Decision: Some non-GMDSS provisions in the RR weremaintained. Resolution 331 as revised by WRC-03 resolves to retain, asan interim measure, the provisions permitting use of VHF channel 16 and2182 kHz for general calling and encourage all vessels carrying maritimeVHF equipment to be fitted with digital selective calling on VHF channel70 as soon as possible. Relevant RR provisions including Article 33, 47,52 and 55 have been revised.

Agenda item 1.10.1“to consider the results of studies, and take necessary actions, relating toexhaustion of the maritime mobile service identity numbering resource(Resolution 344 (WRC-97))”

13. Maritime mobile service identities (“MMSIs”) were used inmany ship borne radiocommunications equipment to uniquely identifyship stations, group ship stations, coast stations, and group coast stations.WRC-97 instructed the Director of the Bureau (“BR”) to monitor thestatus of the MMSI resource and report to each WRC on the anticipatedreserve capacity and expected exhaustion of the resource.

WRC-03 Decision: WRC-03 has revised Article 19 to assist

7

administrations and the ITU in making optimum use of these resources.

Agenda Item 1.10.2“shore-to-ship distress communication priorities (Resolution 348 (WRC-97))”

14. It is important for shore-based search and rescue authorities to beable to communicate with a ship earth station in a distress or safetysituation, even if the ship earth station is engaged in othercommunications (preemption). International Maritime Organization hadsubmitted proposals to the ITU-R that for any GMDSS system, shore-originated search and rescue communications must be given priority. Ifpracticable, this capability should be incorporated in the existing GMDSSsystems. Otherwise, specific manual procedures should be standardized.They considered that future generations of GMDSS systems must includethis capability.

WRC-03 Decision: It is noted that a standard procedure would onlyapply to GMDSS mobile-satellite systems approved for use prior to 1February 2002. Therefore, if a standardized operational procedure isneeded, it could more appropriately be developed in ITU-R SG 8 throughthe formulation of an appropriate study Question. WRC-03 has decidedto suppress Resolution 348 as the related studies have been completed

Agenda item 1.11“to consider possible extension of the allocation to the mobile-satelliteservice (Earth-to-space) on a secondary basis in the band 14 – 14.5 GHzto permit operation of the aeronautical mobile-satellite service asstipulated in Resolution 216 (Rev.WRC-2000)”

15. The band 14 – 14.5 GHz was allocated to MSS (Earth-to-space),except aeronautical mobile-satellite service (“AMSS”), on a secondarybasis after WRC-97. The said band is also allocated to FSS (Earth-to-space), radionavigation, fixed and mobile (except aeronautical mobile)services. ITU-R studies had demonstrated that it is feasible for AMSSnetworks to operate on a secondary basis in the band 14 – 14.5 GHzwithout causing harmful interference to other primary and secondaryservices in the same band.

WRC-03 Decision: It has been decided that AMSS could operate asMSS in the 14 – 14.5 GHz band as a secondary service. Relevant RR

8

provisions have been revised and should provisionally apply as of 5 July2003.

Agenda item 1.12“to consider allocations and regulatory issues related to the spacescience services in accordance with Resolution 723 (Rev.WRC-2000) andto review all Earth exploration-satellite service and space researchservice allocations between 35 and 38 GHz, taking into accountResolution 730 (WRC-2000)”

16. WRC-03 considered various proposals for frequency allocationto the space service in the bands 100 MHz – 1 GHz, 7145 – 7235 MHz,14.8 – 15.35 GHz, 25.5 – 27 GHz, 32 – 32.3 GHz and 35.5 – 38 GHz.

WRC-03 Decision: WRC-03 has decided to suppress Resolution 723and 730 and adopted revisions relating to the frequency allocation inArticle 5 for the space services, including:

♦ Additional allocation in China and some other countries in the band258 – 261 MHz for SRS (Earth-to-space) and space operationservice (Earth-to-space) on a primary basis as per RR No. 5.BE03.

♦ New co-primary allocation for SRS (Earth-to-space) in the band7145 – 7235 MHz and modification to the provision in RR No.5.460 accordingly.

♦ New co-primary allocation for SRS (space-to-Earth) in the band25.5 – 27 GHz.

♦ Deletion of the primary allocation to inter-satellite service in theband 32 – 32.3 GHz.

♦ Addition of RR No. 5.BE02 which specifies the equivalent powerflux density (“epfd”) limit for the EESS (active) or SRS (active)services in the band 35.5 – 36 GHz and adopted a new Resolution[COM 5/3] concerning the use of the band 36 – 37 GHz.

Agenda item 1.13“to consider regulatory provisions and possible identification of existingfrequency allocations for services which may be used by high altitudeplatform stations, taking into account No. 5.543A and the results of the

9

ITU-R studies conducted in accordance with Resolutions 122(Rev.WRC-2000) and 734 (WRC-2000)”

17. Resolution 122 provided interim regulatory provisionsconcerning the use of the bands 47.2 – 47.5 GHz and 47.9 – 48.2 GHzand potential use of the band 18 – 32 GHz by high altitude platformstations (“HAPS”). With the exception of FSS which would requirefurther studies, it had been proposed that HAPS could operate at 27.5 –28.35 GHz and 31.0 – 31.3 GHz without causing unacceptableinterference through appropriate mitigation measures, requiredgeographical separation and frequency guard bands.

WRC-03 Decision: WRC-03 has revised RR No. 5.537A and 5.543Aand adopted two Resolutions [COM 5/10] and [COM 5/11] concerningthe use of the bands 27.5 – 28.35 GHz and 31.0 – 31.3 GHz by someRegion 2 and 3 countries. ITU-R was requested to conduct studies witha view for WRC-07 to considering appropriate revisions of theregulations affecting HAPS, within 300 MHz of spectrum in the bands27.5 – 28.35 GHz and 31.0 – 31.3 GHz.

Agenda item 1.14“to consider measures to address harmful interference in the bandsallocated to the maritime mobile and aeronautical mobile (R) services,taking into account Resolutions 207 (Rev.WRC-2000) and 350 (WRC-2000), and to review the frequency and channel arrangements in themaritime MF and HF bands concerning the use of new digital technology,also taking into account Resolution 347 (WRC-97)”

18. As an ongoing effort to reduce interference to HF distress andsafety frequencies used in the GMDSS, WRC-2000 determined thatgeneral calling from ships should not be permitted on 12290 kHz and16420 kHz no later than 31 December 2003. However, someadministrations had expressed difficulty conforming to the removal of thecalling function on 12290 kHz and 16420 kHz. Moreover use of Morsetelegraphy and narrow band direct printing for maritime mobileapplication were declining. Demands for spectrum for other maritimecommunications such as data communications and introduction of newdigital technology for maritime mobile services was increasing.

WRC-03 Decision: Article 52 concerning the special rules relating tothe use of frequencies, including the use of the distress frequencies 12290

10

kHz and 16420 kHz, has been revised. WRC-03 has adopted Resolution[COM 4/3] concerning the use of frequencies 12290 kHz and 16420 kHzfor safety-related calling and Resolution [COM 4/2] concerning thereview of the frequency and channel arrangements in the MF and HFbands allocated to the maritime mobile service for new digital technology.WRC-03 has modified Appendix 17 to permit, on a voluntary basis, theuse of various channels or bands for initial testing and future introductionof new digital technology.

Agenda item 1.15“to review the results of studies concerning the radionavigation-satelliteservice in accordance with Resolutions 604 (WRC-2000), 605(WRC-2000)and 606 (WRC-2000)”

19. The band 5010 – 5030 MHz was allocated to RNSS in WRC-2000. RR No. 5.443B imposed a provisional limit on aggregate pfd onRNSS, which was subsequently revised by ITU-R SGs, in order to protectradio astronomy services in the adjacent band 4990 – 5000 MHz. ITU-R SGs also concluded that an aggregate epfd and a maximum pfd levelrespectively should be imposed on RNSS transmissions in order toprotect radiolocation and radionavigation services in the bands 1164 –1215 MHz and 1215 – 1300 MHz.

WRC-03 Decision: WRC-03 has suppressed Resolution 604, 605 and606 and approved revised provisions in the concerned bands as follow:

♦ 4900 – 5000 MHz and 5010 – 5030 MHzWRC-03 has adopted Resolution [COM 5/1] and revised theassociated RR footnotes to clarify the application of the pfd/epfdlimits to protect RAS in the band 4900 – 5000 MHz caused by anyGSO RNSS network operating in the 5010 – 5030 MHz band.

♦ 1164 – 1215 MHzA co-primary allocation for RNSS is added in the band 1164 – 1215MHz. Resolution [COM 5/8] gives the epfd limit for the spacestations of RNSS to protect the existing ARNS.

♦ 1215 – 1260 MHzResolution [COM 5/5] has been adopted resolving that noconstraints in addition to those in place prior to WRC-2000 shall beplaced on the use of frequency assignments to stations in the RNSS

11

(space-to-Earth) in the band 1215 – 1260 MHz brought into use until2 June 2000.

Agenda item 1.16“to consider allocations on a worldwide basis for feeder links in bandsaround 1.4 GHz to the non-GSO MSS with service links operating below1 GHz, taking into account the results of ITU-R studies conducted inresponse to Resolution 127 (Rev.WRC-2000), provided that duerecognition is given to the passive services, taking into account No.5.340”

20. ITU-R SGs conducted studies concerning a proposal to allocatethe bands 1390 – 1393 MHz and 1429 – 1432 MHz for the uplinks anddownlinks of MSS feeder links respectively.

WRC-03 Decision: WRC-03 has approved an additional allocation inthe band 1390 – 1392 MHz for FSS (Earth-to-space) on a secondary basisand 1430 – 1432 MHz to the FSS (space-to-Earth) also on a secondarybasis. These allocations are limited to use for feeder links for non-GSOnetworks in the MSS with service links below 1 GHz and the newResolution [COM 5/14] applies.

Agenda item 1.17“to consider upgrading the allocation to the radiolocation service in thefrequency range 2900 – 3100 MHz to primary”

21. The frequency band 2900 – 3100 MHz was allocated to theradionavigation service on a primary basis and to the radiolocationservice on a secondary basis. ITU-R studies shown that radiolocationradars and radionavigation radars are compatible through theimplementation of interference suppression/rejection measures.

WRC-03 Decision: It has been decided that the secondary allocation forradiolocation service in the band 2900 – 3100 MHz be upgraded to theprimary status.

Agenda item 1.18“to consider a primary allocation to the fixed service in the band 17.3 –17.7 GHz for Region 1, taking into account the primary allocations to

12

various services in all three Regions”

22. The band 17.3 – 17.7 GHz was allocated to the FSS (Earth-to-space) on a primary basis and radiolocation service on a secondary basisin all three Regions. There was also a co-primary allocation to BSS inRegion 2.

WRC-03 Decision: WRC-03 has decided that no allocation in the band17.3 – 17.7 GHz be made to the fixed service in Region 1.

Agenda item 1.19“to consider regulatory provisions to avoid misapplication of the non-GSO FSS single-entry limits in Article 22 based on the results of ITU-Rstudies carried out in accordance with Resolution 135 (WRC-2000)”

23. WRC-2000 established single-entry epfd limits in Article 22 tobe met by non-GSO FSS systems in certain parts of the frequency range10.7 – 30.0 GHz to protect GSO FSS and GSO BSS networks.Verification of conformance with the single entry epfd limits contained inTables 22-1 to 22-3 of Article 22 forms an important part of theregulatory examination of any notice for a non-GSO FSS system,performed by the BR.

WRC-03 Decision: No change to the RR was needed and Resolution135 was suppressed.

Agenda item 1.20“to consider additional allocations on a worldwide basis for the non-GSO MSS with service links operating below 1 GHz, in accordance withResolution 214 (Rev.WRC-2000)”

24. ITU-R studies identified no evidence of spectrum congestion ofMSS service links below 1 GHz. Furthermore, the growth of the trafficcould be accommodated in the existing frequency bands without the needfor an additional allocation.

WRC-03 Decision: No additional allocation was given to MSS below1 GHz.

13

Agenda item 1.21“to consider progress of the ITU-R studies concerning the technical andregulatory requirements of terrestrial wireless interactive multimediaapplications, in accordance with Resolution 737(WRC-2000), with a viewto facilitating global harmonization”

25. Terrestrial Wireless Interactive Multimedia (“TWIM”)applications are a vision of future wireless applications capable ofcarrying simultaneously many different radiocommunication services.ITU-R SGs considered that the feasibility on spectrum sharing and theneed for frequency coordination procedures (if any) should be studiedfurther.

WRC-03 Decision: WRC-03 has adopted Resolution [COM 7/2]inviting ITU-R to continue studies on technical, operational andfrequency issues and identify any regulatory impediments that may arisein relation to the introduction of TWIM on a global basis.

Agenda item 1.22“to consider progress of ITU-R studies concerning future development ofIMT-2000 and systems beyond IMT-2000, in accordance with Resolution228 (WRC-2000)”

26. Resolution 228 (WRC-2000) invited ITU-R to continue studieson overall objectives, applications and technical and operationalimplementation for the future development of IMT-2000 and systemsbeyond IMT-2000.

WRC-03 Decision: Resolution 228 as revised by WRC-03 resolves toinvite ITU-R to further study the technical and operational issues relatingto the future development of IMT-2000 and systems beyond IMT-2000and develop Recommendations as required. ITU-R is also invited toreport, in time for WRC-07, on the results of studies on the spectrumrequirements and potential frequency ranges suitable for the futuredevelopment of IMT-2000 and systems beyond IMT-2000.

Agenda item 1.23“to consider realignment of the allocations to the amateur, amateur-satellite and broadcasting services around 7 MHz on a worldwide basis,

14

taking into account Recommendation 718 (WARC-92)”

27. There were primary allocations for amateur service in the band7000 – 7100 kHz in Region 1 and 3 and 7000 – 7300 kHz in Region 2.However, the band 7100 – 7300 kHz was primary allocated tobroadcasting service in Region 1 and 3. There was only 100 kHzcommon allocation for amateur service in the band 7000 – 7100 kHz forall the three Regions. There were long-standing difficulties reported bythe amateur service and limitations placed on the broadcasting servicearound the 7 MHz band since the above ITU-R frequency allocation wasadopted long time ago.

WRC-03 Decision: WRC-03 has decided to align the primary allocationfor amateur service in the band 7100 – 7200 kHz worldwide. Asspecified in a new footnote 5.AC03, the existing primary broadcastingservice in the band 7100 – 7200 kHz in Region 1 and 3 would continueuntil 29 March 2009. China and some other countries have anadditional allocation as given in RR No. 5.AC02bis that the band 7100 –7200 kHz is also allocated to the fixed and mobile, except aeronauticalmobile (R), services after 29 March 2009.

Agenda item 1.24“to review the usage of the band 13.75 – 14 GHz, in accordance withResolution 733 (WRC-2000), with a view to addressing sharingconditions”

28. The band 13.75 – 14 GHz was allocated to GSO FSS sharingwith radiolocation and radionavigation services by the World RadioAdministrative Conference held in 1992. There were limitations to beimposed on all these three services as specified in RR No. 5.503.

WRC-03 Decision: WRC-03 has modified RR No. 5.502 to relax therestriction on antenna size of uplink VSAT for GSO FSS from 4.5 m to1.2 m in the band 13.75 – 14 GHz. In order to protect the existingprimary radiolocation service, WRC-03 has imposed limits on the powerflux density of uplink earth stations using antennas smaller than 4.5 m.According to Resolution [COM 5/15] as adopted by WRC-03, theadministrations of geographically small or narrow countries may exceedthe limitations on FSS earth station power flux density if such operation

15

is in conformance with bilateral agreements with administrationsdeploying maritime radiolocation systems in the 13.75 – 14 GHz.

Agenda item 1.25“to consider, with a view to global harmonization to the greatest extentpossible, having due regard to not constraining the development of otherservices, and in particular of the fixed service and the broadcasting-satellite service, regulatory provisions and possible identification ofspectrum for high-density systems in the fixed-satellite service above 17.3GHz, focusing particularly on frequency bands above 19.7 GHz”

29. High Density Fixed Satellite Service (“HDFSS”) is one whichoperates on a system in the FSS, deploying a large number of ubiquitousearth stations. The satellite systems can be GSO or non-GSO, and usingany of the available technologies.

WRC-03 Decision: WRC-03 has adopted RR No. 5.BC03 which liststhe following frequency bands for HDFSS:

Space-to-Earth17.3 – 17.7 GHz in Region 118.3 – 19.3 GHz in Region 219.7– 20.2 GHz in all Regions39.5 – 40 GHz in Region 140 – 40.5 GHz in all Regions40.5 – 42 GHz in Region 247.5 – 47.9 GHz in Region 148.2 – 48.54 GHz in Region 149.44 – 50.2 GHz in Region 1andEarth-to-space27.5 – 27.82 GHz in Region 128.35 – 28.45 GHz in Region 228.45 – 28.94 GHz in all Regions28.94 – 29.1 GHz in Region 2 and 329.25 – 29.46 GHz in Region 229.46 – 30 GHz in all Regions48.2 – 50.2 GHz in Region 2

WRC-03 has adopted new Resolution [COM 5/6] which gives theguidelines for the implementation of HDFSS.

16

Agenda item 1.26“to consider the provisions under which earth stations located on boardvessels could operate in fixed-satellite service networks, taking intoaccount the ITU-R studies in response to Resolution 82 (WRC-2000)”

30. ITU-R studies concluded that in-motion earth stations on boardvessels (“ESVs”) may successfully operate in the popular frequencybands for FSS in 4/6 GHz and 11/14 GHz without causing unacceptableinterference to the fixed service as well as other satellite services if someconstraints are imposed on the ESV operations.

WRC-03 Decision: WRC-03 has decided that ESV may operate in theband 5925 – 6425 MHz and 14 – 14.5 GHz as FSS. Regulatory andoperational provisions and the operational procedure for ESV are given inResolution [COM 4/20] and Recommendation [COM 4/B] respectively.

Agenda item 1.27“to review, in accordance with Resolutions 540 (WRC-2000) and 735(WRC-2000), the ITU-R studies requested in those resolutions, andmodify, as appropriate, the relevant regulatory procedures and associatedsharing criteria contained in Appendices 30 and 30A and in theassociated provisions”

31. There were on-going studies on sharing criteria in Annex 1 and 4of Appendices 30 and 30A to further reduce the number of unnecessarycoordination between BSS and FSS networks whilst providing adequateand equitable protection to these services.

WRC-03 Decision: WRC-03 has modified Appendices 30 and 30A,including the Articles (mainly specify the regulatory procedures) and theAnnexes (mainly specify the technical methodologies and sharing criteria)to these Appendices. WRC-03 has adopted Resolution [COM 6/4]concerning the application of the grouping concept in Region 1 and 3.Resolution [COM 6/2] has been adopted resolving that the revisedAppendices 30 and 30A shall enter into force on 5 July 2003 with theexception of the revised Annexes, which shall enter into force on 1January 2004.

Agenda item 1.28“to permit the use of the band 108 – 117.975 MHz for the transmission ofradionavigation satellite differential correction signals by ICAO standardground-based systems”

32. New Ground-Based Augmentation Systems (“GBAS”) haveemerged for the transmission of augmentation data for the GlobalNavigation Satellite Service (“GNSS”) to be used by aircraft receivers tosatisfy the stringent accuracy and integrity requirements for GNSSapplications such that they can be used for precision approach andlanding.

WRC-03 Decision: RR No. 5.BA03 as adopted by WRC-03 states thatthe band 108 – 117.975 MHz may be used by the aeronautical mobile (R)service on a primary basis, limited to systems that transmit navigationalinformation in support of air navigation and surveillance functions inaccordance with recognized international aviation standards. Accordingto Resolution [COM 5/2], frequencies below 112 MHz shall not be usedfor the additional aeronautical until all potential compatibility issues withthe lower adjacent frequency band 87 – 108 MHz have been resolved.

Agenda item 1.29“to consider the results of studies related to Resolutions 136 (WRC-2000)and 78 (WRC-2000) dealing with sharing between non-GSO and GSOsystems” 

33. Frequency sharing between GSO FSS networks and non-GSOFSS systems in the 37.5 – 50.2 GHz band (Resolution 136) was currentlyregulated under RR Article 22. As there had been little, if any,deployment of satellite systems to date in the band 37.5 – 50.2 GHz, nooperational studies were conducted since the actual operationalparameters were still unclear. Resolution 78 called for development ofprocedures in case the operational or additional operational limits inArticle 22 were exceeded.

WRC-03 Decision: WRC-03 has revised Resolution 136 inviting ITU-Rto undertake further technical, operational and regulatory studies onsharing arrangements for GSO FSS networks and non-GSO FSSnetworks in the band 37.5 – 50.2 GHz and report the results of these

18

studies to WRC-10. WRC-03 has also adopted Resolution [COM 4/6]concerning the protection of GSO FSS and BSS networks from non-GSOFSS systems in Article 22. Resolution 78 is suppressed.

Agenda item 1.30“to consider possible changes to the procedures for the advancepublication, coordination and notification of satellite networks inresponse to Resolution 86 (Minneapolis, 1998)”

34. ITU-R had an established procedure for the coordination andnotification of satellite networks in orbits. Due to the large number ofsatellite filings, the ITU-R got some 2.5 years backlog to be processed.Such over-filing and processing backlog also led to increasedcoordination work for satellite operators.

WRC-03 Decision: WRC-03 has reviewed and revised the existingprovisions for satellite network coordination, including:

♦ revision to the regulatory period to grant 2-year extension (from 5years to 7 years) for API received by the BR as of 5 July 2003

♦ capping the change in orbital position from the existing 12o to 6o

with effect from 5 July 2003

♦ extending the coordination arc concept in the band 7025 – 7075MHz

♦ revisions to the data to be provided in satellite network filings

♦ checking of satellite network filings under RR No. 9.35

♦ development of rules of procedure to RR

♦ cancellation of overdue network filings

Agenda item 1.31“to consider the additional allocations to the mobile-satellite service inthe 1-3 GHz band, in accordance with Resolutions 226 (WRC-2000) and227 (WRC-2000)”

35. ITU-R SGs concluded the compatibility study between MSS andother services in the 1518 – 1525 MHz and 1670 – 1690 MHz bands.

WRC-03 Decision: WRC-03 has approved a new global allocation to

19

MSS in the band 1668 – 1675 MHz (Earth-to-space) and 1518 – 1525MHz (space-to-Earth). China and some other countries have anadditional allocation as per RR No. 5.BB10 that stations in the MSS to beoperated in the band 1668 – 1675 MHz shall not cause harmfulinterference to her stations in the meteorological aids service. WRC-03has adopted two Resolutions [COM 5/12] and [COM 5/13] which givesdetails about the use of the band 1668 – 1675 MHz.

Agenda item 1.32“to consider technical and regulatory provisions concerning the band37.5 – 43.5 GHz, in accordance with Resolutions 128 (Rev.WRC-2000)and 84 (WRC-2000)”

36. Resolution 128 concerned the protection of the RAS in the band42.5 – 43.5 GHz. In particular, RR No.5.551G imposed a provisionallimit on aggregate power flux-density in the 42.5 – 43.5 GHz bandproduced by all the space stations in any non-GSO FSS (space-to-Earth)or BSS (space-to-Earth) systems in order to protect RAS. Resolution 84dealt with the power flux-density limits in the bands 37.5 – 42.5 GHz forthe FSS, BSS and MSS.

WRC-03 Decision: WRC-03 has decided to suppress Resolution 84 andRR 5.551A concerning the use of the band 37.5 – 40 GHz and 41 – 42.5GHz for satellite service. Article 21 has been revised to include thepower flux density limit for FSS, MSS and BSS operating in the saidbands. WRC-03 has also adopted RR No. 5.BC04 which gives theequivalent epfd produced in the band 42.5 – 43.5 GHz by all spacestations in any non-GSO systems in the FSS (space-to-Earth) or in theBSS (space-to-Earth) operating in the 42 – 42.5 GHz band.

Agenda item 1.33“to review and revise technical, operational and regulatory provisions,including provisional limits in relation to the operation of high altitudeplatform stations within IMT-2000 in the bands referred to inNo. 5.388A/5.BBB, in response to Resolution 221 (WRC-2000)”

37. According to RR No. 5.388A, High Altitude Platform Stations(“HAPS”) might be used as base stations within the terrestrial component

20

of IMT-2000 in the bands 1885 – 1980 MHz, 2010 – 2025 MHz and2110 – 2170 MHz in Regions 1 and 3 and 1885 – 1980 MHz and 2110 –2160 MHz in Region 2. WRC-2000 had adopted provisional power-fluxdensity limits for HAPS operation in the IMT-2000 spectrum in the 2GHz band. According to the ITU-R studies, the WRC-2000 provisionalpfd threshold limits might not adequately protect the 2G PCS and MMDSin Region 2.

WRC-03 Decision: WRC-03 has modified Resolution 221 to include,among other requirements, the pfd limit for the HAPS at the earth surfaceand notification requirements for HAPS.

Agenda item 1.34“to review the results of studies in response to Resolution 539(WRC-2000) concerning threshold values for non-GSO BSS (sound) inthe band 2630 – 2655 MHz, and to take actions as required”

38. The band 2630 – 2655 MHz was allocated to the fixed andmobile services on a primary basis. WRC-2000 identified the band2500 – 2690 MHz as an expansion band for IMT-2000 and introducedResolution 539 which specifies the provisional pfd thresholds for non-GSO BSS (sound) in the band 2630 – 2655 MHz. ITU-R SGssubsequently revised the pfd thresholds for non-GSO BSS (sound) inResolution 539 with a view to avoid placing undue constraints on eithernon-GSO BSS (sound) or terrestrial services.

WRC-03 Decision: WRC-03 has revised Resolution 539 whichamended, among other requirements, the power flux density mask for theBSS (sound) to protect other service sharing the same band in 2630 –2655 MHz. RR No. 5.418bis, 5.418Abis, 5.418Bbis, 5.418Cbis areadded relating to the use of the said band in some Region 3 countries.

Agenda item 1.35“to consider the report of the Director of the RadiocommunicationBureau on the results of the analysis in accordance with Resolution 53(Rev.WRC-2000) and take appropriate action”

39. Resolution 53 called for the updating of the "Remarks" columnsin the tables of Article 9A of Appendix 30A and Article 11 of

21

Appendix 30 to the RR. BR submitted a Report to WRC-03 withinformation on compatibility analyses between R1 and R3 plans and theR2 plan, the R1 and R3 downlink plan to terrestrial services, R1 and R3plans and FSS (including non-planned BSS), except compatibilityanalyses from R1 and R3 feeder-link plan earth stations to terrestrialservices and FSS earth stations operating in the opposite direction.

WRC-03 Decision: WRC-03 has suppressed Resolution 53 and adoptedthe updates to AP30/30A. Resolution [COM 6/3] has been adopted thatinstructed BR to include the results of an up-to-date analysis based on thisResolution in his report to WRC-07 for consideration by the Conference.

Agenda item 1.36“to examine the adequacy of the frequency allocations for HFbroadcasting from about 4 MHz to 10 MHz, taking into account theseasonal planning procedures adopted by WRC-97”

40. It was reported that spectrum available to the broadcastingservice between 4 and 10 MHz were inadequate. These bands are idealfor short- and medium-range coverage (up to 2000 km) during daytimeand are also needed to support longer-range services at night.

WRC-03 Decision: There were changes to the frequency allocation forbroadcasting service in the 7 MHz band as a result of the decision foragenda item 1.23 given in paragraph 27 above. Resolution [COM 4/11]concerning the identification of additional spectrum for the broadcastingservice in the HF bands resolves that ITU-R should carry out studiestaking into account technical, operational, economic and other relevantfactors and bring the results of these studies for consideration of WRC-07.

Agenda item 1.37“to consider the regulatory and technical provisions for satellite networksusing highly elliptical orbits”

41. ITU-R SGs concluded that highly elliptical orbits (“HEO”)systems are non-GSO systems and that HEO systems do not need aseparate definition in the RR. Although ITU-R had initiated studies onfrequency sharing criteria for such HEO satellite systems, there was littleprogress in the respective studies as the technical, regulatory andprocedural aspects of HEO were very broad, complex and multi-

22

dimensional.

WRC-03 Decision: Resolution [COM 4/5] has been adopted concerningthe technical and regulatory procedures relating to the BSS networks,including non-GSO BSS, operating in the 620 – 790 MHz band.

Agenda item 1.38“to consider provision of up to 6 MHz of frequency spectrum to the Earthexploration-satellite service (active) in the frequency band 420 –470 MHz, in accordance with Resolution 727 (Rev.WRC-2000)”

42. ITU-R SGs concluded that frequency sharing by EESS (active)in the band 420 – 470 MHz is feasible.

WRC-03 Decision: WRC-03 has decided to add a new co-primaryallocation worldwide for EESS (active) in the sub-band 432 – 438 MHz.

Agenda item 1.39“to examine the spectrum requirements in the fixed-satellite service bandsbelow 17 GHz for telemetry, tracking and telecommand of fixed-satelliteservice networks operating with service links in the frequency bandsabove 17 GHz”

43. Under the current regulatory environment, TT&C links for FSSnetworks may be implemented in any FSS bands, including the popular6/4 GHz and 14/10 – 11 GHz bands. The current flexibility toaccommodate the additional spectrum requirements for TT&C commanduplinks in bands below or above 17 GHz should meet the needs of FSSnetworks in the foreseeable future.

WRC-03 Decision: No change to the RR was needed.

Enter Into Force of the Provisions Approved by WRC-03

44. Relevant provisions as revised and adopted by WRC-03, exceptthose specified in Article 59 and Resolution [COM 4/25], shall enter intoforce on 1 January 2005. Lists of the new or modified Resolutions andRecommendations adopted by WRC-03 are given in Annex 1 and 2respectively.
