RE: stds-802-16: Published: Development Plan for 802.16.3 Air Interface Standard

Dear Roger,

I have read the 802.16.1 MAC document and I have serious doubts that it is
to dot3 FRD. On the other side, this MAC successfully fulfils its

Trying to modify it in order to support dot3 requirements will actually stop
the 802.16.1
 project. According to my opinion, the two groups are focused on different
 with different bandwidth availability, that require different MACs. It will
take probably
one year to dot3 group to agree on MAC mechanisms, and you can expect some
them as being antagonist to the dot1 MAC mechanisms and philosophy.

Please consider to focus 802.16.1 MAC drafting process to the "above 10GHz"
only. It was a difficult process to reach this stage of the unified MAC
specification, it
will be very risky to invite the negative votes of many of the dot3 members.

I have no doubts that the dot3 group will try to adopt the 802.16.1 positive
elements, as
 part of its work.

Best Regards,

Title: Development Plan for 802.16.3 Air Interface Standard -
        Task Group Revision

Document Number: IEEE 802.16.3-00/03r2

I feel the need to comment on this one, because I think this plan is 
too slow. With people breathing down our necks in this area, I don't 
think we have the luxury of waiting until next March to hear our 
first proposals. If this standard is going to make an impact, we need 
to get going. I think that TG3 should be looking at PHY proposals 
this November, or January at the latest.

On the MAC side, remember that everyone in 802.16 is going to be 
balloting on 802.16.1. There is every opportunity to make sure that 
this MAC fits all of our needs. Once it does, TG3 can focus on 
driving to a PHY draft.
