Re: +++802SEC Ballot: Forward 802.16.2 to Sponsor Ballot

On the original Letter Ballot, we had four negative voters (Florea, 
Germon, Lewis, and Roehr) with a total of 17 "Binding" comments among 
them. The comment numbers are 14, 20, 37, 39, 41, 42, 44, 45, 46, 49, 
50, 53, 54, 57, 63, 95, and 97, as documented in IEEE 802.16-01/01 
<>. If you want the 
details, I'm going to request that you open the file and search for 
"Technical, Binding".

In Recirculation Ballot #2a, Florea and Lewis were satisfied with the 
resolutions and voted Approve. Roehr was unsatisfied with the 
resolution and voted Disapprove again. Germon did not vote, although 
he indicated informally that he accepted the resolution. An 
additional voter, Hamilton, objected to one resolution and went 
negative. As a result of this, there were two binding comments 
recorded in Recirculation Ballot #2a (one each from Roehr and 
Hamilton); Germon was still recorded as Disapprove though he was 
unofficially on the Approve side.

Following #2a, we held an interim session and resolved the #2a 
comments. Hamilton accepted the resolution of his comment. Roehr 
could not attend, but we came to agreement by email. Therefore, in 
Recirc Ballot #2b, there were no remaining negatives to circulate. 
The only responses we received on #2b were "Approve with no comments" 
from Hamilton, Roehr, and Germon. That left no Disapproves on record.

You can find the details of the final Roehr and Hamilton comments in 
IEEE 802.16-01/06 <>. 
For your convenience, I have included a summary below.

I hope this helps to answer your question. If you need more 
information, please let me know.


*Roehr's Suggested Change: [In Table 8-1] Change Heading last column 
from "Spacing for acceptable performance"to "Seperation at which 
Coordination is Necessary"

Balloter's Reason: 60 km spacing is NOT "acceptable performance". 
This is the real essence of my NO vote in original round (comment 34) 
but unfortunately I tied it to first place 60 km was mentioned, in 
vain hope that change would ripple through document. It appears that 
did not happen. With this change I will (reluctantly, because I fear 
"tone"is wrong elsewhere) change my NO to an Accept.

Resolution: Change heading of column to "Spacing at which 
interference is below target level (generally 6 dB below receiver 
noise floor)".
Change heading in column 3 of table 4-1 to correspond with this change.

*Hamilton's Suggested Change: D/U =-5dB for adjacent channel; D/U=-20 
dB for second adjacent channel

Balloter's Reason: If the wording of the new text really is intended 
to indicate that the Undesired carrier level is 20 dB stronger than 
the Desired carrier, then the new proposal is a dramatic change from 
the old (although confusing) spec of 0 dB. It is not apparent how the 
proposed -20 dB D/U ratio is justified and it is a major design 

It is not clear how these levels are justitifed as "spillover" and if 
the proposed tolerance has been analyzed, or is intended to apply for 
all modulation types covered under the 802.16.1 proposal (e.g. 64 

Resolution: [This is rather long. See pp. 6-7 of IEEE 802.16-01/06].
