Re: [STDS-802-16] The new 802.22 PAR
In addition, I'd like to see any studies, documents and message thread
that the PAR document and responses to .16 comments states to possess to
support the assertion that there is no 802 wireless tech that would
satisfy the perceived requirements.

Ofer,
You have a very nice idea.
Actually we already have in LE Coexistence SG charter to address the
issue
of behavior of 802.16 compliant systems, when primary users are
detected. We
always considered that regulators will provide detection requirements,
as
happened in 5GHz, for radars. Regarding TV bands, may be possible that
802.18 (or 802.22), accumulating already significant knowledge, will
help in
defining these rules. We always considered the detection requirements
being
not part of 802.16 PHY/MAC protocols.
However, 802.18 may try to convince FCC that only 802.22 should be
allowed
in this band, which is similar with some kind of band allocation for a
standard (like GSM, UMTS,etc.). Such a proposal makes sense for improved
co-existence (even if it is not mentioned in 802.22 PAR). Here again,
802.19
and the 802.16 LE Coexistence SG may play a role, to define the
coexistence
between wireless access systems, like 802.16 and 802.22, and for sure,
collaboration is the key word.
I will try to talk with Carl, as 802.22 interim chair, about his views
on
these issues. I hope that we will be able to build a solid collaboration
process.
Another issue may be drafting requirements for PHY/MAC protocols in TV
bands: in spite our opinion, Carl was convinced that 802.16 MAC/PHY do
not
comply with TV bands requirements. We should look in a positive way at
his
views and not exclude that some modifications may be requested for these
bands. Will be very useful if 802.18 SG1 will define "Requirements for
PHY/MAC protocols in TV bands". These will allow us to both assess
compliance with requirements and amend 802.16 standard, if necessary. I
am
not aware of such assessment process in 802.18-SG1, but if actually has
taken place, will be really interesting to see the relevant documents.
Kind Regards,
Marianna

Marianna, Roger,
How about approaching the 802.22 interim chair to join efforts with the
LE
group we have? I read in their reply to 802.16's comments that the
802.18
group was not aware of the relaxation of the lower limit to the
frequency
band, and I would think that coexistence with TV broadcasting is very
much
aligned with coexistence with other LE equipment.
Such approaches for joining efforts had been done in the past by the
group.
I recall we sent such a letter to the "First Mile" group (802.?).
Comments are welcomed.
Ofer
