stds-802-16: Re: [802SEC] +++ SEC EMAIL BALLOT +++ Motion: 802.16a to SponsorBallot

Dear SEC:

I understand Stuart's position in voting Disapprove. 802.11, of 
course, has the right to oppose sending a draft to Sponsor Ballot. 
However, I'd like to put the 802.11 discussion into perspective.

While much of 802.16a concerns licensed bands, license-exempt bands 
are also included. 802.16 is concerned about license-exempt 
coexistence and remains willing to address the issues. Please note:

*The section of the 802.11 minutes that Stuart posted makes it clear 
that this was not a technical discussion. Perhaps the strongest 
statement in favor of the directed position was that "they should 
have assured us [coexistence issues] were addressed beforehand." I 
agree that we could have made a more vigorous effort to review our 
coexistence with 802.11 in advance. However, it is neither a rule nor 
a tradition that WGs review coexistence plans with other WGs in 
advance of Sponsor Ballot. We were open to discussion on the issue, 
and our drafts are available using the 802.11 password. We informed 
other WGs in advance of our intent and assumed that they would take 
the initiative to raise their concerns in advance.

*Our primary coexistence mechanism is Dynamic Frequency Selection 
(DFS). Our 802.11 liaison also Chairs 802.11h, which is developing 
802.11's DFS mechanism. He worked on our DFS techniques and assured 
us that they were coordinated and compatible with 802.11h. This 
discussion also took place in January and led to an 802 position 
statement on DFS that was supported by all three WGs.

*Our DFS mechanism was much less clearly specified in Draft 2, to 
which 802.11 had access, than in Draft 3, which we developed in St. 

*The motion on the floor shows that, during WG Letter Ballot, we 
rejected one comment (0221) because it would weaken license-exempt 

*We hope to address any coexistence concerns, including additional 
coexistence mechanisms, during Sponsor Ballot. Several 802.11 and 
802.15 members have enrolled in the Sponsor Ballot Group. Also, Paul 
followed my recommendation to add the 802.11 and 802.15 chairs to the 

If the SEC decides that 802.16a can't go to Sponsor Ballot until 
802.11 accepts its licensed-band coexistence content, then we will 
have an extremely long delay in the progress of 802.16a. This "Just 
Say No, Without Comments" policy and would deal a significant blow to 
cooperation between Working Groups and would be an unfortunate turn 
of events.
