2. IEEE Work Plan
Ofcom presentation on the Digital Dividend in the UK and Cognitive Radio
Presentation on license exempt operation in the Netherland Antilles
M.1450 approved by Excom
Meet with TGz chair to discuss 5 GHz operation of DLS
Met with and to finalize the Petition for Reconsideration; to be continued PM2

3. TVWS Petition for Reconsideration
FCC R&O on the unlicensed use of the White Space; published 2/17, comments due by 3/18
We have developed a petition for reconsideration to maximize the usability of this spectrum for Wi-Fi devices
IEEE has a similar petition for their cause
Final petition must be from , so must be agreed to by both .11 and .22
Some members developed a response to the .22 petition – 11-09/239r2
Would like to have full WG support in the negotiations

4. The Issues In agreement The contention
A- Fixed devices (base stations) should be allowed to have multiple fixed client/slave devices
B- Sensing for television signals should not be mandated by the Commission
C- Fixed Base Station Height Should Be Based on HAAT Rather than AGL and not limited to 30m AGL
The contention
D- PSD Limits and Minimum Occupied Bandwidth Should Be Specified; and RF Mask
Three sensing points

5. Situation
hosted the Friday March 6th teleconference discussing 22-09/26r0 and 11-09/239r2
is evolving their position in response to 11-09/239r2
See 22-09/26r1, which takes note of issues raised in 09/239r2
22-09/26 is evolving to become the position

6. Sensing
believes that sensing requirement for personal portable devices limit product feasibility; challenging to battery powered devices that utilize power saving mechanisms
“The sensing threshold for wireless microphones should be -107 dBm rather than -114 dBm” - requires significant battery power and time
“Part 74 devices need to be sensed within 2 seconds, not 60 seconds” – Wake up from sleep mode, etc, makes this difficult
“Synchronized quiet periods are necessary for incumbent sensing” – GPS clock undetectable indoors; others too unstable
We prefer database control of access to spectrum

7. Motion
IEEE WG supports the comments of wng-comments-on input-to petition-for-reconsideration as a formal input to the RR-TAG in their development of a Petition for Reconsideration to the FCC TVWS R&O, FCC
Moved: Rich Kennedy
Seconded: Peter Murray
Vote:
Yes 59
No 0
Abstain 12

8. The Results
At the mid-weel plenary I asked the group to approve our input to the RR-TAG development of a petition for reconsideration to the FCC TVWS R&O
In the PM1 session the group approved their final petition: 18-09/039/r4
Three major points of contention between 11 and 22
22 wanted synchronized quiet periods – rejected
22 wanted 2 sec maximum detect time for microphones – rejected
11 wanted to relieve personal portable devices of sensing requirement – rejected
11 wanted to allow active connection with the database to manage contention - accepted
