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.

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 Langeler Michwave Tech. Patrick Leary wrote: >Jon, > >Why is that the case?
