Normis,
Here it is some candidate gps hardware, thanks to the guys that spent time looking into this:
http://www.packetflux.com/ if it works for canopy, it can work for us too
http://www.trimble.com/tmg_acutime2k.shtml it looks very promising
Please try to understand how important channel reuse is for wireless isp that have many subscribers.
This is not something the casual user that set up a link or two will request, that’s for sure.
However, being able to reuse channels on the same site is a must for a carrier grade platform that enables wisp to reach economy of scale connecting hundreads of subscribers on a site.
I’m personally working for a wisp with thousands subcribers, we use mainly mikrotik/nstreme with very good results and we are very satisfied with it.
Unfortunalty, on many sites we are now hitting a wall, we cannot squeezee more subscribers on the AP and there are only a few channels… We cannot even get more sites since they would interfere with each other, not being in synchronized transmission.
Please have a serious look into the feasibility of GPS sync or some other simpler alternative solutions like:
-simple sync: two or three radios in the same board transmitting at the same time. (this could be very easy to do)
-or single radio that transmitts on a channel and receive on another.
-or any other simple solution that avoiding co-location and site-to-site interference enables channel reuse.
