Patrick, ditto on the 3650 band. However the reality is that self and external
interference in the UL world is all too common. You say UL bands or at
least VL doesn't need GPS capability because of so much capacity. If
you want I can get you a list of wifi/trango/etc.-to-Canopy 'converts'
that will tell you otherwise.
Licensed carriers use GPS to greatly diminish what we experience as common day
interference problems. IMO I can't blame the FCC for not giving more
spectrum than they have as we've already trashed what we've been given.
Lastly, what Moto did was brought GPS sync to the UL world however as
standard option and in very economical form factor, not expensive
chassis and such. If you haven't already, get your VL guys with your
WIMAX guys and you could have a clear winner down the road! :)

Jon,
For sure I'm all over GPS for all licensed (world of small channels) and
when there is a small amount of spectrum to work with in UL. For
example, in the coming 3650MHz band, GPS should be a must for PMP. Same
with scaled 900 (we offer it there). It is just not needed with VL. What
for? It already gives massive capacity without any re-use. Even with GPS
and re-use I do not think Canopy can get close to the amount of capacity
VL can offer. Frankly, even if we had it for VL no one would buy it.
No argument from me on the scheduled MAC front, except to the extent
that in UL it needs to come with good interference mitigation (not
talking about self-inflicted interference) techniques to make it useful.

Hey Patrick, GPS...there's many reasons and it's not a canopy vs
alvarion debate from my standpoint, more so a scheduled mac(canopy,
wimax, 3G...) vs unscheduled(wifi, VL, currently Trango). I'd predict
that as wisp education progresses, they will realize the power of
scheduled mac and GPS support. By then maybe the rest of the BreezeMAX
code will have made way to the VL engineers and everyone can be happy
:-)

Jon,
Why is that the case? You really think GPS on Canopy is some cool
feature? Canopy must have GPS to function. Without it, it kills itself.
It is all to prevent self-inflicted interference (remember, Canopy does
not even have ATPC) and to allow for channel re-use. Other systems,
like
VL, do not need it. It provides far more capacity than Canopy, so it
does not need to re-use channels and with basic channel planning you
don't have issues with self-interference.
