Eldad Perahia, Xiaoming Peng January 2012 Background (1/4) CWPAN mmwave project group approached 802.11ad in July 2010 expressing interest in exchanging information between groups issues to discuss import of 60 GHz test equipment into china 45-50 GHz band only two channels in 60 GHz in China A liaison was established between 802.11 and CWPAN. The chair of CWPAN 60GHz project group was selected as the liaison https://mentor.ieee.org/802.11/dcn/10/11-10-0869-01-0wng-a-liaison-inquiry-to-china-wpan.ppt https://mentor.ieee.org/802.11/dcn/10/11-10-0921-01-00ad-china-wpan-liaison.ppt Eldad Perahia, Xiaoming Peng

Eldad Perahia, Xiaoming Peng January 2012 Background (2/4) Nov 2010, CWPAN requested information regarding copyright permission for CWPAN to modify 802.11ad spec for 45-50 GHz operation https://mentor.ieee.org/802.11/dcn/10/11-10-1332-00-00ad-china-wpan-mmwave-liaison-w-802-11.ppt Jan 2011 presented official response from IEEE staff to CWPAN The IEEE doesn’t normally give other groups permission to modify its standards If China WPAN would like to propose improvements or changes to an IEEE standard we’d be happy to work with you to do that The next step would be to create an IEEE project proposal   – can we work together on that? also requested more regulatory information on 45-50 GHz in China in order to determine whether to start new 802.11 project or modify 802.11ad PAR https://mentor.ieee.org/802.11/dcn/11/11-11-0083-06-00ad-january-report.ppt, slide 18 Eldad Perahia, Xiaoming Peng

Eldad Perahia, Xiaoming Peng January 2012 Background (3/4) March 2011, held a joint meeting between 802.11ad and CWPAN IEEE reaffirmed that IEEE will not give copyright permission to an outside organization to modify an IEEE spec. Modifications need to be done within IEEE CWPAN promised to provide a wish list to 802.11ad in a few months provided 802.11ad tutorial to CWPAN, https://mentor.ieee.org/802.11/dcn/11/11-11-0459-01-00ad-tgad-overview-for-cwpan.pptx July 2011 CWPAN reported that they started a new study group on 40-50 GHz in Sept 2010, and this activity will be separate than their 60 GHz project CWPAN 60 GHz has a functional requirement of 3 logical channels presented proposal to modify TGad protocol to support coexistence between narrow channels and 11ad channels https://mentor.ieee.org/802.11/dcn/11/11-11-1034-00-00ad -china-wpan-mmwave-liaison-w-802-11.pptx Eldad Perahia, Xiaoming Peng

Eldad Perahia, Xiaoming Peng January 2012 Background (4/4) Nov 2011 Bruce presented proposal for working relationship with CWPAN Background: CWPAN wishes to modify the 11ad specification in ways that were not known of by 11ad during its development including such items as China specific spectrum allocations and channelization Summary of proposal: Start a new project to amend 802.11+TGad, e.g. study group, new PAR, new Task Group Mutual exchange of documentation between 802.11 and CWPAN Initial ideas on Task Group meeting locations in Asia, attendance, voting rights New task group led by CWPAN principle Details regarding the operation of the Task Group require work during the study group https://mentor.ieee.org/802.11/dcn/11/11-11-1570-00-0000-cwpan-opportunity.pptx CWPAN response positive and supportive 802.11ad, 802.11 WG, and 802 EC approval of formation China MM-Wave (CMMW) study group Eldad Perahia, Xiaoming Peng

Eldad Perahia, Xiaoming Peng January 2012 Summary from 11/1570 on meeting locations in Asia, attendance, voting rights CWPANad interim meetings could be convened in Beijing or other suitable Asian location. CWPANad voting rights could be maintained on attendance of CWPANad meetings only, or perhaps CWPAN and IEEE 802.11 could agree to provide each other balloting rights. CWPAN response on voting and attendance CWPAN agreed the principle of maintaining the voting rights of CWPANad on attendance of CWPANad meetings only [Obtaining voting right]: It is suggested that participants who attend three CWPANad meetings per year including at least one CWPANad interim meeting will obtain the voting rights of CWPANad [Maintaining voting right]: It is suggested that participants who has obtained the voting right of CWPANad, needs to attend two CWPANad meetings including at least one CWPANad interim meeting to maintain the voting right. [Note 1]: Voting right of CWPANad is not equivalent to the voting right of IEEE 802.11. To obtain the voting right of IEEE 802.11, it needs to follow the existing regulation [Note 2]: We expect CWPANad participants to attend at least one CWPANad interim meeting per year to ensure enough communication and better understanding with Chinese participants Eldad Perahia, Xiaoming Peng

Eldad Perahia, Xiaoming Peng January 2012 Discussion in 802.11ad in Atlanta on meeting locations in Asia, attendance, voting rights Establishing Task group voting rights is the wrong way to go, because it splits voting rights in 802.11. It is better to have the interim CWPANad meetings be adhoc meetings with no implications on voting rights. Request more explanation about the need for having separate meetings in Asia given that more and more mainland Chinese attendees are actually attending these 802.11 meetings. Response: from past experience, many individuals from mainland China have trouble obtaining visa to travel to the US. Holding meetings in Asia will allow easier attendance.
