Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the TAG of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair <shellhammer@ieee.org> as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.19 TAG.

Tutorial Outline Introduction Need for Coexistence July 2010 Tutorial Outline Introduction Brief overview of FCC rules Standards activities in TVWS Need for Coexistence The Coexistence Problem TVWS Use Cases IEEE 802.19.1 Project Project Title, Scope and Purpose Project Timeline System Design Document Possible Coexistence Solutions Leverage incumbent protection mechanisms for TVWS coexistence Modify network/device parameters to improve coexistence Steve Shellhammer, Qualcomm

July 2010 FCC Rules on TVWS In November 2008 the FCC issued a Report and Order (R&O) on unlicensed wireless use of unused TV channels, called TV white space (TVWS) A number of petitions for reconsiderations were filed and the FCC still needs to respond to the petitions. Current forecasts are for the FCC to respond by the end this year. In any given location in the US there are a number of TV channels unused by the broadcast industry. The number varies significantly from location to location Each channel is 6 MHz wide Channels are in the VHF and UHF frequency bands Details in a subsequent slide FCC defines two classes of TVWS devices Fixed Portable Steve Shellhammer, Qualcomm

Permissible TV Channels July 2010 FCC Rules on TVWS TV Channel Frequency Band Frequency (MHz) Allowed Devices 2 VHF 54 – 60 Fixed 5 – 6 76 – 88 7 – 13 174 – 216 14 – 20 UHF 470 – 512 21 – 35 512 – 602 Fixed & Portable 36 602 – 608 Portable 38 614 – 620 39 – 51 620 – 698 Permissible TV Channels Steve Shellhammer, Qualcomm

FCC Rules on TVWS Fixed devices use outdoor antenna Permitted TX Power July 2010 FCC Rules on TVWS Fixed devices use outdoor antenna Between 10 and 30 meters above ground Permitted TX Power Fixed – 30 dBm with up to 6 dBi antenna gain Portable – 20 dBm with no antenna gain Adjacent TV Channels Fixed – Not permitted Portable – Reduce power to 16 dBm Strict Out-of-band Emissions Classes of Portable Devices Mode I – Client Mode II – Access Point Steve Shellhammer, Qualcomm

FCC Rules on TVWS Geo-location & Database access Spectrum Sensing July 2010 FCC Rules on TVWS Geo-location & Database access Must be supported in both Fixed and Portable Mode II devices Accuracy of 50 meters FCC will certify the official databases Spectrum Sensing ATSC and NTSC TV signals Wireless microphones Sensing down to -114 dBm (approx -15 dB SNR) Will consider “sensing-only” devices but with much more stringent testing required Steve Shellhammer, Qualcomm

July 2010 Non-US TVWS Rules Other regulatory regions are also preparing TVWS rules Some of the regulatory regions working on TVWS rules include Canada United Kingdom Singapore Nederland Antilles Finland The rules in these regions are likely to have some similarities with the US rules but will likely not be exactly the same In other parts of the world the TV channel bandwidths are 6, 7 and 8 MHz. So TVWS support for these different bandwidth is expected Steve Shellhammer, Qualcomm
