distribution.

To 802.16 member,
It has come to my attention that several members of 802.16 wish to preserve
full backward compatibility
between 802.16-2004 and 802.16e. I will be submitting a simple letter to
Nescom that request that the
revised PAR of 802.16e be changed to maintain full backward compatibility.
If you agree with this position, please send me an E-mail confirming your
position, and I will add your name to the letter.
Best Regards,
J. Pierre Lamoureux

Dear NesCom Members,
We are writing as members of the 802.16 in response to the letter from the
Chair of the 802.20 working group asking to reject the proposed 802.16e PAR
modifications.
While we do not agree with all the assertions of the 802.20 letter, we do
agree that the main differentiator between the two groups is that 802.16e
mobile WMAN standard must maintain backward compatibility to the previous
fixed WMAN standard defined in 802.16-2004.
The 802.16e standard must clearly establish a mechanism for backward
compatibility so that subscriber units of 802.16e systems can interoperate
with 802.16-2004 base stations
using the same modulation scheme (SCa, OFDM, or OFDMA) and vice versa.
Scalable FFT size should not be an impediment to backward compatibility.
We think that the current wording of the revised PAR does not address
backward compatibility in sufficient detail and should be modified before
being approved.
Sincerely,
Pierre Lamoureux,
.....
