I do not know how the Radwin Sync works. With Canopy, you do not lose
bandwidth unless you do not have the timing the same. You can adjust
settings in such a way as to not step on yourself and still have different
bandwidth profiles with Canopy.
I do not see why sync would lose any bandwidth,
like half.
Does that help?

Going in a different direction...
Can you reuse a given frequency on every sector around a tower (4x or
6x), or are you limited to something less than that? Do you get full
capacity on each sector, or are you limited to some percentage of that
full capacity if you use the same channel all the
With standard FSK Canopy (7/14 Mbps) you can re-use frequencies on
back-to-back sectors only. There is no throughput hit for doing so.
Think about what the GPS sync does- it causes all AP transmission
timeslots to occur simultaneously, and all receive timeslots to be
synchronized. So colocated
and then ALL APs transmit simultaneously, not sequentially, correct?

The biggest problem with your idea will be the fact you're on the ground -
not going to work too well for 2.4 and 5.x. 900 will be better, but not
ideal.
