Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEEs name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEEs sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, 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 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.

2. sg-whitespace-09/0019r0 Submission January 2009 Steve Shellhammer, QualcommSlide 2 Abstract This presentation begins the discussion on the impact of the recent FCC TV White Space Report and Order on IEEE 802 –Discussion on the FCC R&O –Discussion on Impact on IEEE 802

3. sg-whitespace-09/0019r0 Submission January 2009 Steve Shellhammer, QualcommSlide 3 FCC Report and Order Unlicensed Operation Two classes of devices –Fixed –Portable Permissible Channels –Fixed: VHF and UHF except 36-38 –Portable: UHF 21-51 except 37 Fixed devices use outdoor antenna –Between 10 and 30 meters above ground

4. sg-whitespace-09/0019r0 Submission January 2009 Steve Shellhammer, QualcommSlide 4 FCC Report and Order 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

5. sg-whitespace-09/0019r0 Submission January 2009 Steve Shellhammer, QualcommSlide 5 FCC Report and Order 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 –Must be supported in all devices –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

6. sg-whitespace-09/0019r0 Submission January 2009 Steve Shellhammer, QualcommSlide 6 Impact on IEEE 802 The VHF and UHF frequencies offer significantly better propagation characteristics than the 2.4 GHz and 5 GHz frequency bands IEEE 802.22 is addressing the Fixed-to-fixed network topology There may be interest in these frequencies for longer-range operation –Longer range WLAN –Longer range WPAN (Smart Utility Networks) –Other?

7. sg-whitespace-09/0019r0 Submission January 2009 Steve Shellhammer, QualcommSlide 7 Impact on IEEE 802 To utilize these frequencies certain capabilities must be provided –Internet access (often available in current networks) –Location awareness –Network Quieting for Spectrum Sensing –Spectrum Sensing Techniques –Improved Spectral Mask IEEE 802 should consider coexistence of multiple technologies all utilizing these frequencies
