3. 802.11af Status before March Meeting
Comment resolution going on…
Group had telcos on Jan 31, Feb 7, 14 and 21, March 6th.
Reviewed Ofcom requirements and discussed possible implications to 11af spec. Representation of device identification and type, antenna map and WSM are main issues. The requirements can have impact on TGaf schedule. TGaf needs to decide if we shall wait to address Ofcom requirements before the LB.
Plan for March meeting:
Approve meeting and teleconference minutes
Review the results of LB171
Approve the LB171 comment spreadsheet in 11-11/277r27
Approve speculative draft D1.06 as the working draft
Review the progress since January

Current af Status
Approved comment spreadsheet (277r27) and speculative draft 1.06 as working draft.
Did not complete LB171 comment resolution this week, instead laying the ground work for a Clause 23, TGaf PHY submission in May. All PHY comments (197) still need to be resolved.
Document 424 (Broadcom and Qualcomm) : Presentation providing status of down-clocking options for 6MHz and 8MHz channels.
For 6 MHz TV channels: Propose to consider 5 MHz (down-clocking of 4 or 8) or 6 MHz channelization (down-clocking of 3.3 or 6.6). Good support in SP.
For 8 MHz TV channels: Propose to down-clocking of 5 to have 8MHz or 6 to have slightly less than 8MHz channel BW. Good support in SP.
Strong support for defining non-contiguous operation of the minimum channel width per regulatory domain
