Roger,
Thank you for the clarifications.
 
I approve.

Jerry,

No, this band is not allocated to IMT-2000. It
has been identified for IMT-2000 applications,
but this doesn't preclude other applications. The
allocations in the ITU Radio Regulations, of
course, are not to standards like IMT-2000 but to
Radiocommunication Services, such as the mobile
service, the fixed service, the mobile satellite
service, etc.

There are currently many service allocations in
the band. The details have been compiled by Joint
Task Group 6/8/9 in Document 6-8-9/6-E. If you
check there, you will find many space as well as
terrestrial services. That's a key reason that
JTG 6-8-9 was created. JTG 6-8-9 is "tasked to
conduct studies of the technical, operational and
regulatory provisions applicable to the use of
the band 2 500-2 690 MHz by space services in
order to facilitate sharing with current and
future terrestrial services..."

I prefer not to delete that sentence. First of
all, it includes specific content on the types of
user devices supported by the standard. Also,
while I agree that the statement is conjectural,
I disagree that we are writing to a standards
body. We are writing to a body preparing an
analysis of future scenarios, and that analysis
needs to be based on assumptions of about those
scenarios. I think that it is appropriate to 802
to take the position that 802.16 will be a
"significant part of future broadband wireless
services." If we didn't believe that, we may as
well close down our work. But I am convinced that
the 266 people already preregistered for our
interim in China next month do believe it.

The entire document was reviewed by the 802.16
WG. The WG unanimously passed this motion on 18
November: "To task the ITU-R Liaison Official,
Josť Costa, working with the ad hoc ITU-R liaison
group active at Session #34, to draft a
contribution to ITU-R JTG 6-8-9 on the topic
described in IEEE L802.1604/14. The WG Chair is
authorized to submit the document to the IEEE 802
Executive Committee for approval by email ballot,
with the intent to submit to ITU-R as an IEEE
contribution." Although I was authorized to
submit the ad hoc's output for EC approval, I
first posted it to the 802.16 reflector for
comments. Comments were accepted and resolved.
The revised version was again posted to the
reflector for comment, but no further comments
were received.
