1. Richard Kennedy (RIM) is the chair of the group. Chair called meeting to order: 8:05 pm EST

2. Introduction 2.1. Chair welcomed participants to the Task Group teleconference. 2.2. Chair introduced the officers of the group. 2.2.1.Chair: Rich Kennedy (Research In Motion) 2.2.2.Vice-chair and Webex Facilitator: Peter Ecclesine (Cisco) 2.2.3.Recording Secretary: Zhou Lan (NICT) 2.3. Chair reminded participants to record their attendance by sending mails to [email protected] and [email protected].

3. Agenda approved as posted.

4. Administrative items 4.1. Chair reviewed the patent policy and meeting guideline slides. Are there any questions on the slides? None. 4.2. Chair asked: Are there any patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) that the participant believes may be essential for the use of that standard? None.

5. Chair reviewed the PAR Scope and Purpose, Purpose, Principles and Vision/Outcome. 5.1. Wen Gao (Thomson) asked for elaboration of the third bullet of the principles about the backward compatibility. Wen Gao also said that adopting 5/10/20 MHz channels may have an issue of wasting channel bandwidth for European countries where channels are 8 MHz wide. 5.2. Peter Ecclesine (Cisco) answered that because TVWS is a new band, the task group doesn’t have to worry about the existing 802.11 devices operating in that band. Peter Ecclesine said the regulations of European countries are still in process, when the market becomes available, amendments can be made to address the issue. 5.3. Tushar Moorti (Broadcom) raised an observation that lower channel spectrum utilization isn't a great enough reason to complicate the standard (yet). 5.4. Chair raised another observation that the group can spend more than one year to address the efficiency issue and put the commercialization behind by three years, chair preferred to work with the current FCC 6MHz channel and make amendment later for other counties. 5.5. Wen Gao said that efficiency is still an issue even if only 6 MHz channel is considered. 5.6. Peter Ecclesine suggested bringing this discussion to face to face meeting.

6. Chair reviewed the call for proposals document (doc.: IEEE 802.11-09/1048r0) 6.1. Zhou Lan (NICT) suggested to change the deadline for the notification of intend to Feb. 19th. 6.2. Hearing no objections, chair decided to change the deadline for the notification of intent from Feb. 16th to Feb. 19th. 6.3. Padam Kafle (Nokia) asked for clarification of the technical proposals, does it mean draft document or just technical contributions? 6.4. Chair answered that it can be technical presentation or draft text if someone would like to propose; draft text will have to meet the guidelines and will have priority. 6.5. Tuncer Baykas (NICT) said the number of sessions in March may not be enough to present all the proposals. And it gives too less time for preparing the presentation. Having the deadline of submission open till May will not delay the schedule. 6.6. Peter Ecclesine answered we can leave this issue open till the next teleconference and decide based on how many submissions are there and how they align with the principles of the group.

7. Peter Ecclesine reviewed Annexes I and J of 11 mb draft document and document doc.: IEEE 802.11-09/1048r0 to give an overview of what we expect to see in the proposals 7.1. Joe Kwak (InterDigital) asked whether the group will consider the feedback from the regulators. 7.2. Chair answered that the group is closely tracking the feedback from the regulators not only for U.S. but also European countries. 7.3. Yohannes (NICT) asked why Canada needs to be included given the regulation of Canada is not finalized yet. 7.4. Peter Ecclesine responded that the current regulation of Canada already allows the operation in TVWS. 7.5. Steve Shellhammer (Qualcomm) asked that the current 11 OFDM 5MHz waveform doesn’t meet the FCC spectrum mask requirement, how will the group deal with this issue. 7.6. Peter Ecclesine responded the FCC will change the rules; they understand that 55 dBr is not practical for low power devices, unlike the part 101, high power devices it was initially used for. The group will not try to follow current FCC rules which are not reasonable for milliwatt devices. 7.7. The Chair stated that the FCC understands that making regulations that defy commercial feasibility is a mistake. 7.8. Joe Kwak asked there was a discussion on either modifying clauses 17 and 20 or creating a new PHY to not to confuse the band for the backward compatibility. It is not on the agenda. 7.9. Peter Ecclesine responded that if people want to modify clauses 17 and 20, they can come up with text and propose how to solve this fundamental problem. 7.10. Zhou Lan asked whether the modification of PHY parameters that gives performance improvement can be in the scope. 7.11. Peter Ecclesine responded that according to the PAR, there is no requirement of performance improvement, so it will be difficult. 7.12. Joe Kwak asked for confirmation that the group will not modify the fundamental parameters such as SIFS, to extend the range. Chair confirmed that and stated that in order for the IEEE 802 ExCom to approve the PAR it was necessary to specify that this amendment was for wireless local area networking, making it a different project from 802.22. 7.13. Kathyayani Srikanteswara (Intel) commented that the implementation may give longer range, but the group is not targeting the range extension due to the distinct identity of the task group.

8. Chair reviewed the March meeting plane and agenda 8.1. Steve Shellhammer confirmed the joint meeting with 22 and 19 is postponed to May. 8.2. Padam Kafle asked “Don’t we need to decide the selection procedure for the proposals?” Chair responded that it will be discussed at the Orlando meeting. 8.3. Zhou Lan asked what would be the right procedure to adopt the current call for proposals document. 8.4. Chair responded it is up to the chair to decide when to issue a call for proposals and the deadline according to the P&P, but the group needs to agree.

9. Chair asked if there is any other business, hearing none, we are adjourned at 9:30 pm EST.
