November 2008 doc.: IEEE 802.11-08/1254r1 November 2008 Abstract On November 4th the FCC voted to allow Part 15 devices to operate on unused TV channels www.fcc.gov/sptf New FCC part 15 rules will be published very soon – as soon as Nov 14th - becoming law the day of publication http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-286566A1.pdf Objective of SG What is already in 802.11k/w/y Proposed Scope and Work of WGSG Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

November 2008 Objective It is proposed that an 802.11 Study Group be established to assess whether there is justification to form a task group to define an 802.11 standard for operation in [US TV] white space Peter Ecclesine, Cisco Systems

US TV channel allocations November 2008 US TV channel allocations http://www.fcc.gov/mb/engineering/usallochrt.pdf 2,3,4 54-72 MHz (wavelength ~six meters) 5,6 76-88 MHz 7-13 174-216 MHz 14-20 470-512 MHz 21-51 512-692 MHz (wavelength ~60 cm) Note that channel 37 is reserved for radio astronomy (608-614 MHz) Note that some of channels 14-20 are shared with Public Safety in dense urban markets Peter Ecclesine, Cisco Systems

November 2008 Quotes from FCC Doc 286566 “The rules will allow for both fixed and personal/portable unlicensed devices. Such devices must include a geolocation capability and provisions to access over the Internet a data base of the incumbent services, such as full power and low power TV stations and cable system headends, in addition to spectrum-sensing technology. The data base will tell the white space device what spectrum may be used at that location.” “The Commission also has required that devices include the ability to listen to the airwaves to sense wireless microphones as an additional measure of protection for these devices.” Peter Ecclesine, Cisco Systems

November 2008 More from FCC Doc 286566 “The Commission also will permit certification of devices that do not include the geolocation and data base access capabilities, and instead rely solely on spectrum sensing to avoid causing harmful interference, subject to a much more rigorous approval process.” “The Commission will explore in a separate Notice of Inquiry whether higher-powered unlicensed operations might be permitted in TV white spaces in rural areas.” Peter Ecclesine, Cisco Systems

Proposed SG Scope Identify technical scope November 2008 Proposed SG Scope Identify technical scope Determine impacts on IEEE 802.11, for example: Sensing requirements and reporting Definition of ‘geolocation’ protocols Whether an 802.11 TV band specific modulation is needed ‘Application Profiles’ for TV white space Decide whether a TG is needed, and if so define PAR and 5Criteria. Peter Ecclesine, Cisco Systems

November 2008 802.11k-2008 and 802.11w 802.11k-2008 Radio Measurement provides geolocation query/response and radio measurement operations. It also creates and updates a radio neighborhood map and report. After Dec 12, 2008, it will be freely available for download at http://standards.ieee.org/getieee802/802.11.html 802.11w Protected Management Frames is in Sponsor Ballot and provides management frame protection. http://www.ieee802.org/11/Reports/tgw_update.htm Peter Ecclesine, Cisco Systems

Tethered operation is part of 802.11y-2008 November 2008 Tethered operation is part of 802.11y-2008 A licensed operator can control dependent stations with Dependent Station Enablement Uses the registered location of a fixed transmitter as part of the ‘callsign’ for all stations, and makes them uniquely identify themselves Control can be out-of-band, but is not secure (yet) http://www.sensibleradio.com/11y has highlights, as does https://mentor.ieee.org/802.11/file/08/11-08-0437-01-000y-tgy-overview.ppt Peter Ecclesine, Cisco Systems

Proposed SG Work A decision regarding the creation of a Task Group November 2008 Proposed SG Work A decision regarding the creation of a Task Group Creation of PAR and 5Criteria with the objective of producing an amendment which defines IEEE 802.11 operation in [US TV band] white space. Determine relationships with other IEEE 802 groups. Peter Ecclesine, Cisco Systems
