Got that right (that it's not an option currently). DSRC may be using a
wifi variant (narrowed 802.11a), but the DSRC usage is not intended to be
the same traffic as "consumer wireless internet" that wifi typically
carries. DSRC has a variety of functions, mostly related to highway traffic
"for the safety of the public". As such, DSRC traffic requires various
priorities, the most stringent demanding lower latency than could be
achievable unless the channels are dedicated to DSRC functionality.
Unlicensed functions for "any" purpose are contemplated to take place on
UNII channels as they are designated for today, and the DSRC channel access
layer for safety functions may be totally different than 802.11 MAC. We
were headed that way when I left that committee's work (it was one of the
few things that I'd contributed to their effort that stuck) and from my
reading of the FCC order, I think it's still that way (discussion of control
channels). As such there's a sensitivity of DSRC members that dual-band
units not be able to operate using standard 802.11 MAC on the DSRC channels
which could put the dedicated DSRC safety functions at risk.

Actually I am able to use the entire 900 MHz band here. Selectivity of
tuners has never been an issue the FCC seems very willing to consider when
adjacent uses are being suggested. As I understand it the systems being
proposed are low power vehicle communications. I am not trying to say I am
all for them having more spectrum. In fact I think that vehicles and WISPs
should be able to add those bands together with the existing UNII bands
and anyone make use of all of it but that is not an option currently. The
proposal, as I remember it, was for vehicles to be allowed to use this
space for low power vehicle communications. Our attorney, Kris Twomey,
told us it is of little to no concern to WISPs. I could not find anything
regarding this that was terribly important to WISPs. If I am wrong then
please tell me how I am wrong and why it is important for WISPs to take a
stand of any kind in this proceeding and then we will consider it. I
promise I have not made my mind up yet on this and I would be glad to take
a stand if one is needed. I welcome others feedback.
Thanks,
Scriv

yep, just like paging's "Just above" the 900 mhz unlicensed bands but
makes
926 and above useless. See ... ?

Actually I was told that this is above the existing UNII band frequencies.
I
was told this has nothing to do with existing frequencies we use for our
networks.

Dawn,
Could you tell us what interest you believe there should be for WISPs
involving this proceeding? I am doubting it as much as I would like to
know your personal thoughts on the subject. Kris Twomey looked into this
for me some time back and told me it is of no concern for WISPs. If you
see something he did not though please forward it along.
Thank you,
Scriv

All,
Below is something WISPA should be paying attention to.
WTB Orders (FCC-06-110)
AMENDMENT OF THE COMMISSION'S RULES REGARDING DEDICATED SHORT-RANGE
COMMUNICATION SERVICES IN THE 5.850-5.925 GHZ BAND (5.9 GHZ BAND),
AMENDMENT OF PARTS 2 AND 90 OF THE COMMISSION'S RULES TO ALLOCATE THE
5.850-5.925 GHZ BAND TO THE MOBILE SERVICE
And here is the link for those of you who would like to look into this
in further detail.
