Abstract
On November 4th the FCC voted to allow Part 15 devices to operate on unused TV channels
New FCC part 15 rules will be published very soon – as soon as Nov 14th - becoming law the day of publication
Objective of SG

Objective
It is proposed that an Study Group be established to assess whether there is justification to form a task group to define an standard for operation in [US TV] white space

Quotes from FCC Doc
“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

More from FCC Doc
“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.”

8. Proposed SG Scope Identify technical scope
November 2008
Proposed SG Scope
Identify technical scope
Determine impacts on IEEE , for example:
Sensing requirements and reporting
Definition of ‘geolocation’ protocols
Whether an 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.

802.11k-2008 and w
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
802.11w Protected Management Frames is in Sponsor Ballot and provides management frame protection.

10. Tethered operation is part of 802.11y-2008
November 2008
Tethered operation is part of y-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)
has highlights, as does

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 operation in [US TV band] white space.
Determine relationships with other IEEE 802 groups.

[US TV] white space SG motion
Request approval by IEEE 802 LMSC to form an Study Group to examine the opportunities afforded by the FCC’s TV white space actions of November 4, 2008 , with the intent of creating a PAR and five criteria to form a new Task Group.
