[Dan] While it is important to analyze
potential coexistence issues in every target band, a safe way to
preempt most of these problems is to adopt the same (or more
stringent) emission and susceptibility levels specified
by incumbent wireless technology standards and relevant ITU
Recommendations. Clearly, compliance with such standards is not
enough - in certain deployment cases - to guarantee coexistence and this
is where guidelines are needed. I also support the suggestion to
identify and document the most likely target bands for deployment of
802.20 systems.
1.2.2 Liaison - This should be
definitely left to the Coexistence TG to decide what other entities to
have liaison with. The decision is going to depend, partly, on the
selection of "target bands". I think it would be premature for the CG to
make any recommendation on liaisons other than in the general sense, e.g.
liaison with regulatory authorities, ITU-R, CEPT, etc., which the TG will
most probably have anyways.
[Dan] The
heading of section 1.2.2 was "Rules of the road" and my view is that it
includes: 1) a general outline of the CE work plan, 2) analysis
methodologies, 3) liaison activity within IEEE 802 and with external
standards and regulatory bodies, 4) documents release
plan.

Analysis of what is in the various
documents
2.1 Performance
(mandatory):
[Dan]
I have compiled and adapted the table of contents from the minimum
performance specifications (sections headings in the case of IEEE
802.16.2-2001) of four wireless technologies: GSM, TDMA-136, cdma2000 and
IEEE 802.16. The similarities among the first three are quite evident.
802.16's approach is to make equipment design recommendations, not to set
minimum performance standards. In addition, unlike the other wireless
technologies, 802.16.2-2001 also covers antenna design issues.

All,
We will have our next conference
call as scheduled on October 10th, 1:00 - 2:00 PM EDT. The conference
bridge information will be announced later.
We will be focusing on the items
1 and 2 of the "to do" list prepared at the Singapore meeting. Item 6 is
also related and we'll discuss that if time permits. I repeat these
items here for your reference.
