Chair shared FCC document 47 CFR 101.105 with the task group – Interference Protection Criteria Chair shared FCC document 47 CFR 101.141 with the task group – Microwave Modulation Minimum Payload Capacity 20 MHz 89.4 Mbit/s at 50% loading

Chair reviewed 802.11-05/0340r0 which was submitted in 2005. 802.16 and CSMA-CA

Agenda reviewed from Monday's meeting (11-06/0066r1)

Peter wishes to add an item - status of WG and status of PAR.

Peter providing information about: IEEE SA NESCOM - commented - PAR was weak as approved in November. Grammar issues - needs complete sentences in section 13, Scope.

Item 13 changed to be a complete sentence: “The scope of the proposed project is the application of 802.11 based systems to the 3650-3700 MHz band in the USA.”

Change approved by WG chair and 802 chair. No further SG action needed. No other changes in PAR. Updated PAR will be on server as 802-11y-IEEE-Submitted-PAR as PDF received from NESCOM.

Attendance sheet circulated. Chair requests indicating primary affiliation.

Agenda accepted.

Call for volunteers to chair the task group. Peter is committed to chair the study group.

----Presentations----

11-06/0172r0 - Range in 802.11y and Ramifications on OFDM Symbol Format - Steve Shellhammer, et al.

Discussion - Chair:

Issue of 801.11j didn't deal with GI correctly - 'j' needed 2x the 0.8 usec GI.

Regulatory - what is the PSD really required? Is it really total PSD, or active protocol to support other users of the channel? 25 watt limit - may not need to be contigious in frequency though.

------

Chair noted copy of PAR is on TGy temp folder on file server. 802-11y.pdf, later renamed to as 802-11y-IEEE-Submitted-PAR

Reviewing items in presentation 11-06/0056r0. Email on reflector is encouraged to determine what market, what is our advantage.

Review FCC regs for use of the 3650Mhz band - 47 CFR 90.7. CBP definition Sharing on the band must be fair. Scalable for future equipment. "future proof protocol". Provide reasonable opportunities for other transmitters to operate.

Chair notes CSMA, with tweaks might be able to fit these requirements.

Will regulatory compliance be achieved? (KJR) Review FCC proceedings 04-151 filing, etc.

Discussion of definition of QoS term - The premise is "If you can't control the medium, you can't control QoS". Reviewed 11-05/0340r0 Contention Based Protocol and 802.16 QoS.

Chair recommended using David Allen's approach (presented in Monday’s meeting).

Should SG send comments to FCC? Possibly thru 802.18. Chair notes it may be not worth it. Reviewed part of 11-05/0336r0 – CBP telecom minutes 13 April 2005 [NTIA comments on ETDocket03-108APPENDIXA]

Have to cover US Gov't being primary allocation in 3650MHz band.

Should the SG/TG take on the task of defining an "FCC" level of solution of the regs?

Chair requested items for Future SG/TG work. None submitted at this time.

New Motions for WG? None heard. Telecon dates: Feb/1 Feb/15 Mar/1 Mar/22 – subsequently changed to Feb 8 and Feb 22 (every other wednesday, same telcon info)
