stds-802-16-tg4: RE: FW: Wireless HUMAN in 5GHz



Roger,
Thank you for the information.  I will work with Jim and his SG to assure
that the WirelessHUMAN standard meets the requirements for coexistence
outlined in its PAR.

David,

Last Thursday, the 802 SEC created an Executive Committee Study Group 
on Coexistence, following the information that you had passed along 
to us at the Closing Plenary.

My understanding is that this group was created to consider how 
coexistence across Working Groups should best be addressed. As a 
Study Group, it is a temporary entity, chartered until the end of the 
July session. It is supposed to make recommendations as to how 802 
should deal with coexistence in the future.

Jim Lansford chairs the Study Group. His note below shows that he is 
taking an open attitude and is not pre-defining output of the group.

I expect that the primary coexistence issues between 802.16 and the 
other 802 Working Groups will be related to our 802.16b 
(WirelessHUMAN) project, since it is our only effort in 
license-exempt spectrum. As the Coexistence Liaison for 802.16's TG4 
(which is leading the 802.16b development), you are the appropriate 
lead contact for 802.16 in this area. I appreciate your agreement, 
last week, to take primary responsibility.

As to how 802 will eventually address coexistence, I don't know. I 
know that the WirelessHUMAN group has been very proactive in staying 
in touch with 802.11 and 802.15 since before its creation as a Study 
Group, even traveling to a joint 802.11/802.15 interim and presenting 
a tutorial at the November 802 Plenary. In spite of all this, the 
existence of the project seems to have escaped some of the 
participants until this week. Perhaps this indicates that 
communications remain the first priority.

I agree with Jim Lansford that it is essential to keep the flames 
down on these issues. Progress is going to take hard work and 
constructive engagement.

Along Jim's suggestion of the discussion forum, I recommend a 
separate reflector. Copying multiple Working Group reflectors can 
lead to too much heat. By the way, I have copied the 802.16 list on 
this message because I want everyone to know of the existence of this 
activity. I think that followups ought to be limited to the TG4 
reflector rather than sent to the whole Working Group.

Regards,

Roger
