Thank you for your comments. I look forward to that discussion in San

Rich,
I agree with you that time should be set aside in San Francisco for some
real discussions on possible scenarios and strategies that the IEEE 802
should consider regarding the TV white space.
For example, if 802.11 begins a project on TVWS, the question of
coexistence dealt with by 802.19 gets even more relevant. The
discussions
that we have in 802.19 on the different coexistence schemes (TDM, FDM
and
CDM) are very useful. TDM is obviously the scheme that provides the
best
isolation between systems in near-far situations where the
desired-to-undesired signal differential can become very large, but this
requires systems synchronization. The isolation available from FDM is
limited by the filter performance and the flexible bandwidth systems
would
only work if a number of SAW filters at IF was available to provide the
needed rejection for the different bandwidths to avoid saturating the
ADC
in a near-far situation. CDM just does not provide for sufficient
isolation from different systems if the power is not centrally
controlled.
The item that was raised by Joe Kwak during the last 802.22
teleconference
with respect to a synchronized mode for 802.11 proposed by AT&T opens
interesting avenues, especially that synchronization of 802.22 and
802.16
systems seems to be possible for coexistence because of their 10 ms and
5
ms frames. Adding 802.11 to this synchronized structure would have
promises, especially that quiet periods could then be synchronized for
incumbent sensing.
With respect to 802.22, we have reached the stage of second WG ballot
and
we are starting the second round of comments resolution in San
Francisco. The Draft has improved considerably and this has allowed
more
focused comments leading to quicker resolution. Work will continue on
improving the Draft towards sponsor ballot. I can indicate that the
rumors
that you heard on a major architectural change are not founded.
However,
802.22 will be considering the extension of its standard to
personal/portable applications for full interoperability between the
different fixed/mobile/portable 802.22 applications. The 802.22 PHY
layer
already allows it. This extension had been opposed by the broadcasters
earlier but now that the rules have been established by the FCC, such
opposition no longer seems to exist. The plan, if the WG agrees, is to
re-submit the 802.22a PAR updated to avoid procedural difficulties to
the
EC in November.
