Frank, to add to peterE's response and perhaps to address another use of the term "backhaul", WiFi is being used as a backhaul in the way that Peter mentioned, but also to bring bandwidth to remote locations and then distributing with the mesh. to be effective, it really needs to be a multi-radio backhaul architecture (Strix, Belair, MeshDynamics) so that the individual links can be optimized (antenna configs, ack timeouts, etc...). I have one application where bandwidth is being backhauled into a small mountain community from 12 miles away with two hops (first hop is 9 miles, second hop is 3 miles). My longest link on a production network is 15 miles. This is using 400mW 5.8GHz radios with 29dbi parabolic antennas. Throughput is consistently 22Mbps. I'm sure you probably remember some of our earlier conversations where I was asking questions about the ack timeout delay.....obviously the information went to good use:-) BW
