WHAT SHOULD BE DONE TO PREPARE PAR AND 5C

1. Define TV white space and its requirements.• Geolocation and database access• Sensing TV signal and other incumbent signals

2. Identify use cases.

3. Identify conceptual system level technical requirements, not detailed technical requirements from identified use cases.

• Detailed system design is not necessary: these requirements can be achieved through various technologies which can be proposed later: At this stage, a specific technology does not need to be considered for this standard.

4. Judge whether these requirements can justify the need to use TV white space for applying existing standard technologies (and possibly new technologies).

• Review existing technologies first.• Identify advantages from use of TV white space

5. Prepare PAR and 5C based on technical requirements identified.Slide 6

PAR: NEEDS FOR PROJECT (2)

Need for the Project:

With the global transition to Digital TV (DTV), sub-Gigahertz RF spectrum is becoming available, much of it for unlicensed, license exempt and/or lightly licensed use. This project will make the necessary MAC and PHY changes to enable 802.15.4g products to take advantage of this additional spectrum with its improved propagation characteristics and improved indoor wall penetration and hence range.

802.11af: With the global transition to Digital TV (DTV), sub-Gigahertz RF spectrum is becoming available, much of it for unlicensed, license exempt and/or lightly licensed use. This project will make the necessary MAC and PHY changes to enable 802.11 products to take advantage of this additional spectrum with its improved propagation characteristics and improved indoor wall penetration and hence range.

802.22: There is a large, untapped market for broadband wireless access in rural and other unserved/underserved areas where wired infrastructure cannot be economically deployed. Products based on this standard will be able to serve those markets and increase the efficiency of spectrum utilization in spectrum currently allocated to, but unused by, the TV broadcast service.

PAR: ADDITIONAL EXPLANATORY NOTES8.1 Additional Explanatory Notes (Item Number and Explanation):5.2 Scope - TV White Space is defined in the US by the November 2008 FCC Part 15 Subpart H Television Band Devices rules and the September 2010 FCC 10-174 Second Memorandum Opinion and Order. Ofcom (UK) is in the process of making this Digital Dividend band available, and the EU has conducted a consultation on the TV band. The project will adapt to changes in the regulations, as they progress. It is in the best interest of users and the industry to strive for a level of coexistence between wireless systems in the TVWS bands. This standard provides mechanisms for coexistence with other systems operating in the TV bands.

802.11af: 5.2 Scope - TV White Space is defined in the US by the November 2008 FCC Part 15 Subpart H Television Band Devices rules. Ofcom (UK) is in the process of making this Digital Dividend band available, and the EU has conducted a consultation on the TV band. The project will adapt to changes in the regulations, as they progress. It is in the best interest of users and the industry to strive for a level of coexistence between wireless systems in the TVWS bands. This standard provides mechanisms for coexistence with other systems operating in the TV bands.

802.22: Wireless Regional Area Network (WRAN) – a point-to-multipoint network for operation over large, potentially sparsely populated areas � �(e.g. rural areas) for fixed user terminals, taking advantage of the favorable propagation characteristics in the VHF and low UHF TV bands as well as for portable user terminals operating over a likely smaller area with sufficient margin to the fixed base station. The unique requirements of operating on a strict non-interference basis in spectrum assigned to, but unused by, the incumbent licensed services requires a new approach using purpose-designed cognitive radio techniques that will permeate both the PHY and MAC layers. The IEEE 802.18 Study Group chartered to develop this PAR does not believe that any existing IEEE 802 PHY/MAC combination can meet these requirements without extensive modifications. The Study Group has therefore concluded that placing the project in a new Working Group is the most efficient approach. The Working Group will maintain ongoing communications with the joint effort of the IEEE Communications and EMC Societies as it determines the technical definition of non-interference, harmful interference, their measurement and acceptable mitigation. It is in the best interest of users and the industry to strive for a level of coexistence between wireless systems. The IEEE 802.22 WG provides mechanisms for coexistence with other systems in the TVWS band. One approach is a common coexistence mechanism that may be used by other TVWS systems; other approaches are also possible. Slide 14

5C: 1. BROAD MARKET POTENTIAL (1)

Slide 17

a) Broad sets of applicability. On November 4, 2008, the United States FCC approved Report & Order 08-260, allowing unlicensed use of TV band spectrum, in accordance with Part 15. Subpart H of FCC rules. Ofcom (UK) is in the process of making this Digital Dividend band available, and the EU has conducted a consultation on the band. Other regulatory domains are expected to follow.By applying this TV white space, a variety of WPAN existing applications enjoy advantages of this space over the bands assigned so far. It opens up markets with its unique features and provides broad sets of applicability.

b) Multiple vendors and numerous users The standard will be optimized to meet the cost and other requirements to ensure broadening the markets and increasing the number of target users by utilizing advantages of TV white space. Current Wireless services in these WPAN areas use the 700 MHz, 1 GHz and 2.4 GHz bands, with data rate of at least 40 kbits per second but not more than 1000 kbits per second. There are many vendors of IEEE 802 wireless equipment for indoor and outdoor operation, and it is expected that there will be several offering equipment for this band.

c) Balanced costs (LAN versus attached stations) The changes to meet FCC regulatory requirements are not expected to impact the cost of clients versus base stations, which is expected to be the same as the 2 GHz bands. The registration costs for operation in this band are not significant, unlike spectrum in bands that are auctioned.

5C: 1. BROAD MARKET POTENTIAL (2)

802.11afA standards project authorized by IEEE 802 shall have a broad market potential. Specifically, it shall have the potential for:

a) Broad sets of applicability. On November 4, 2008, the United States FCC approved Report & Order 08-260, allowing unlicensed use of TV band spectrum, in accordance with Part 15. Subpart H of FCC rules. Ofcom (UK) is in the process of making this Digital Dividend band available, and the EU has conducted a consultation on the band. Other regulatory domains are expected to follow.

b) Multiple vendors and numerous users. Current Wireless ISP services in these areas use the 900 MHz, 2.45 GHz and 5 GHz bands, operating under Part 15 rules. There are many vendors of IEEE 802 wireless equipment for indoor and outdoor operation, and it is expected that there will be several offering equipment for this band.

c) Balanced costs (LAN versus attached stations). The changes to meet FCC regulatory requirements are not expected to impact the cost of clients versus base stations, which is expected to be the same as the 5 GHz bands. The registration costs for operation in this band are not significant, unlike spectrum in bands that are auctioned.

The fundamental radio and baseband architecture of the WLAN is well known, and adding another supported band is a well-understood process. b) Reasonable cost for performance. The extension of IEEE 802.11a products and/or chipsets to cover TV band operation is similar in cost to that of adding 3650 MHz operation as specified in IEEE 802.11y. c) Consideration of installation costs. The installation cost of Part 15 Subpart H compliant WLAN equipment will not change from that of installing current 5 GHz band equipment.

SAMPLE PARS FROM OTHER STANDARDS (1)

802.22• Title: Standard for Information Technology -Telecommunications and information

exchange between systems - Wireless Regional Area Networks (WRAN) - Specific requirements - Part 22: Cognitive Wireless RAN Medium Access Control (MAC) and Physical Layer (PHY) specifications: Policies and procedures for operation in the TV Bands

• Scope: This standard specifies the air interface, including the cognitive medium access control layer (MAC) and physical layer (PHY), of point-to-multipoint wireless regional area networks comprised of a professional fixed base station with fixed and portable user terminals operating in the VHF/UHF TV broadcast bands between 54 MHz and 862 MHz.

• Purpose: This standard is intended to enable deployment of interoperable 802 multivendor wireless regional area network products, to facilitate competition in broadband access by providing alternatives to wireline broadband access and extending the deployability of such systems into diverse geographic areas, including sparsely populated rural areas, while preventing harmful interference to incumbent licensed services in the TV broadcast bands.

802.22• Need for the Project: There is a large, untapped market for broadband wireless access in rural and other

unserved/underserved areas where wired infrastructure cannot be economically deployed. Products based on this standard will be able to serve those markets and increase the efficiency of spectrum utilization in spectrum currently allocated to, but unused by, the TV broadcast service.

• Stakeholders for the Standard: Manufacturers and users of semiconductor, personal computer, enterprise networking devices, consumer electronic devices, home networking equipment, mobile devices.

• 8.1 Additional Explanatory Notes (Item Number and Explanation): Wireless Regional Area Network (WRAN) – a point-� �to-multipoint network for operation over large, potentially sparsely populated areas (e.g. rural areas) for fixed user terminals, taking advantage of the favorable propagation characteristics in the VHF and low UHF TV bands as well as for portable user terminals operating over a likely smaller area with sufficient margin to the fixed base station. The unique requirements of operating on a strict non-interference basis in spectrum assigned to, but unused by, the incumbent licensed services requires a new approach using purpose-designed cognitive radio techniques that will permeate both the PHY and MAC layers. The IEEE 802.18 Study Group chartered to develop this PAR does not believe that any existing IEEE 802 PHY/MAC combination can meet these requirements without extensive modifications. The Study Group has therefore concluded that placing the project in a new Working Group is the most efficient approach. The Working Group will maintain ongoing communications with the joint effort of the IEEE Communications and EMC Societies as it determines the technical definition of non-interference, harmful interference, their measurement and acceptable mitigation. It is in the best interest of users and the industry to strive for a level of coexistence between wireless systems. The IEEE 802.22 WG provides mechanisms for coexistence with other systems in the TVWS band. One approach is a common coexistence mechanism that may be used by other TVWS systems; other approaches are also possible.

802.11af Wireless LAN in the TV White Space• Need for the Project: With the global transition to Digital TV (DTV), sub-Gigahertz RF

spectrum is becoming available, much of it for unlicensed, license exempt and/or lightly licensed use. This project will make the necessary MAC and PHY changes to enable 802.11 products to take advantage of this additional spectrum with its improved propagation characteristics and improved indoor wall penetration and hence range.

• Stakeholders for the Standard: Manufacturers and users of semiconductor, personal computer, enterprise networking devices, consumer electronic devices, home networking equipment, mobile devices.

• 8.1 Additional Explanatory Notes (Item Number and Explanation): 5.2 Scope - TV White Space is defined in the US by the November 2008 FCC Part 15 Subpart H Television Band Devices rules. Ofcom (UK) is in the process of making this Digital Dividend band available, and the EU has conducted a consultation on the TV band. The project will adapt to changes in the regulations, as they progress. It is in the best interest of users and the industry to strive for a level of coexistence between wireless systems in the TVWS bands. This standard provides mechanisms for coexistence with other systems operating in the TV bands.

15.4g• Title of Standard: : IEEE Standard for Information Technology - Telecommunications and Information Exchange Between

Systems - Local and Metropolitan Area Networks - Specific Requirements - Part 15.4: Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for Low Rate Wireless Personal Area Networks (WPANs) - Amendment: Physical Layer(PHY) Specifications for Low Data Rate Wireless Smart Metering Utility Networks)

• Scope: (See explanatory notes in Section 8.1)This Standard defines an amendment to IEEE 802.15.4. It addresses principally outdoor Low Data Rate Wireless Smart Metering Utility Network requirements. It defines an alternate PHY and only those MAC modifications needed to support its implementation. Specifically, the amendment supports all of the following:

– Operation in any of the regionally available license exempt frequency bands, such as 700MHz to 1GHz, and the 2.4 GHz band.

– Data rate of at least 40 kbits per second but not more than 1000 kbits per second– Achieve the optimal energy efficient link margin given the environmental conditions encountered in Smart

Metering deployments.– Principally outdoor communications– PHY frame sizes up to a minimum of 1500 octets– Simultaneous operation for at least 3 co-located orthogonal networks– Connectivity to at least one thousand direct neighbors characteristic of dense urban deployment

Provides mechanisms that enable coexistence with other systems in the same band(s) including IEEE 802.11, 802.15 and 802.16 systems

15.4g• Purpose: To provide a global standard that facilitates very large scale process control applications such as the

utility smart-grid network. This amendment supports large, geographically diverse networks with minimal infrastructure. Smart Metering Utility Networks can potentially contain millions of fixed endpoints. The communication range, robustness, and coexistence characteristics required for this class of application have not been met with existing 802 standards (See explanatory notes in Section 8.1).

• Need for the Project: The need for a standard to promote orderly and quick evolution of smart-grid networks has been recognized in the recently passed energy legislation by the U.S. Congress (EISA 2007; Energy Independence & Security Act of 2007), which calls on National Institute of Standards and Technology (NIST) to work with standards bodies (such as IEEE) to develop protocols and standards for the smart-grid network. In the European Union, the need is no less urgent and similar standardization mandates, such as the EU’s 20/20/20 plan, are in process worldwide. The responses received by and presented to the 15.4g Study Group indicate an already large and rapidly growing market for wireless Smart Metering applications that fit the objectives of 802.15, but are not satisfied by existing IEEE 802 standards. (See explanatory notes in Section 8.1). The 802.15.4g Study Group tutorial held in Denver in July 2008 was attended by well over 100 participants. More than 40 participants responded to the call for interest in participating in the 802.15.4g standardization activity.Utility networking and very large scale industrial applications have requirements to keep infrastructure to a minimum, scale to millions of nodes across diverse geographical environments, and do so with carrier grade reliability. To reach every node in the network a Wireless Smart Metering Utility Network needs the capability to vary radio range while providing for high spectral reuse (See explanatory notes in Section 8.1).

Area Networks (WPANs).

• Scope: To provide a recommended practice to provide the architectural framework enabling WPAN devices to promote interoperable, stable, and scaleable wireless mesh topologies and, if needed, to provide the amendment text to the current WPAN standards that is required to implement this recommended practice.

• Purpose: This project facilitates wireless mesh topologies optimized for IEEE 802.15 WPANs. Mesh Topologies provide:– Extension of network coverage without increasing the transmit power or the

receiver sensitivity– Enhanced reliability via route redundancy– Easier network configuration– Better device battery life

15.6• Title of Standard: : Standard for Information Technology - Telecommunications and

Information Exchange Between Systems - Local and Metropolitan Area Networks - Specific Requirements - Part 15.6: Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for Wireless Personal Area Networks (WPANs)used in or around a body.

• Scope: This is a standard for short range, wireless communication in the vicinity of, or inside, a human body (but not limited to humans). It can use existing ISM bands as well as frequency bands approved by national medical and/or regulatory authorities. Support for Quality of Service (QoS), extremely low power, and data rates up to 10 Mbps is required while simultaneously complying with strict non-interference guidelines where needed. This standard considers effects on portable antennas due to the presence of a person (varying with male, female, skinny, heavy, etc.), radiation pattern shaping to minimize SAR* into the body, and changes in characteristics as a result of the user motions. *SAR (Specific Absorption Rate) measured in (W/kg) = (J/kg/s). SAR is regulated, with limits for local exposure (Head) of: in US: 1.6 W/kg in 1 gram and in EU: 2 W/kg in 10 gram. This limits the transmit (TX) power in US < 1.6 mW and in EU < 20 mW.

15.6• Purpose: The purpose is to provide an international standard for a short range (ie about human body range), low

power and highly reliable wireless communication for use in close proximity to, or inside, a human body. Data rates, typically up to 10Mbps, can be offered to satisfy an evolutionary set of entertainment and healthcare services. Current Personal Area Networks (PAN)s do not meet the medical (proximity to human tissue) and relevant communication regulations for some application environments. They also do not support the combination of reliability (QoS), low power, data rate and noninterference required to broadly address the breadth of body area network applications.

• Need for the Project: There is a need for a standard optimized for ultra low power devices and operation on, in or around the human body to serve a variety of applications including medical and personal entertainment. Examples of the applications served by the proposed standard are: Electroencephalogram (EEG), Electrocardiogram (ECG), Electromyography (EMG), vital signals monitoring (temperature (wearable thermometer), respiratory, wearable heart rate monitor, wearable pulse oximeter, wearable blood pressure monitor, oxygen, pH value , wearable glucose sensor, implanted glucose sensor, cardiac arrhythmia), wireless capsule endoscope (gastrointestinal), wireless capsule for drug delivery, deep brain stimulator, cortical stimulator (visual neuro-stimulator, audio neuro stimulator, Parkinson’s disease, etc…), remote control of medical devices such as pacemaker, actuators, insulin pump, hearing aid (wearable and implanted), retina implants, disability assistance, such as muscle tension sensing and stimulation, wearable weighing scale, fall detection, aiding sport training. This will include body-centric solutions for future wearable computers. In a similar vein, the same technology can provide effective solutions for personal entertainment as well. The existence of a body area network standard will provide opportunities to expand these product features, better healthcare and well being for the users. It will therefore result in economic opportunity for technology component suppliers and equipment manufacturers.

15.7

• Title of Standard: PHY and MAC standard for short-range wireless optical communication using visible light

• Scope: This standard defines a PHY and MAC layer for short-range optical wireless communications using visible light. The visible light spectrum extends from 380 to 780 nm in wavelength. The standard is capable of delivering data rates sufficient to support audio and video multimedia services and also considers mobility of the visible link; compatibility with visible-light infrastructures; impairments due to noise and interference from, e.g., ambient light; health and other environmental effects; and a MAC layer that accommodates visible links. The standard will adhere to any applicable eye safety regulations

• Purpose: The purpose of this standard is to provide a global standard for short-range optical wireless communication using visible light. The standard will provide (i) access to several hundred THz of unlicensed spectrum; (ii) immunity to electromagnetic interference and noninterference with RF systems; (iii) additional security by allowing the user to see the communication channel; and (iv) communication augmenting and complementing existing services (such as illumination, display, indication, decoration, etc.) from visible-light infrastructures.

• Need for the Project: Visible light is drawing great interest as a new communication medium due to the following recent developments. Firstly, solid-state light sources are rapidly replacing conventional ones in signaling, illumination and display infrastructures. It thus becomes possible to carry communication data on such light sources. Secondly, the visible band is free from frequency regulation and RF interference so that it is well suited to RF crowded or RF restricted environments. Thirdly, the unique feature of visibility can enhance the physical-layer security and offer intuitive usage. Given the growing expectation of ubiquitous connectivity in all settings and environments, the need for unlicensed, high bandwidth, easy to use wireless communications technology has never been greater. Potential applications include secure point-to-point communication, indoor Location Based Service (LBS), secure point-to-Multipoint communication (office, hospital, airplane), Intelligent Transportation System (ITS), information broadcast, and etc. A visible light communication standard will provide economic opportunities to equipment manufacturers, component suppliers, service providers, and infrastructure operators.
