- Get off the 2.4 GHz range. Move up to 5. As for licensed vs. unlicensed, I'm getting mixed input. I'm fairly certain that if the price is right and the frequency is 5GHz+, it won't be a factor. Also, I'll be very glad to separate the bridge from the client access points so that allows for more options. Every solution at this range can easily do 20+ Mbps so throughput is no longer a factor.
It looks like your fresnel zone is 14ft (according to a previous poster) and you're currently using relatively low power radio waves. Have you considered using something like Free Space Optics? For under $100, you can build yourself a couple of RONJAs[1] and test out what the signal is going to be like - that runs at 10Mbit, and can stay in place as a backup once you then buy a FSO device from a proper manufacturer (MRV make some nice ones) and you're looking at 100Mbit for some money, 1000Mbit for quite a lot of money and 10000Mbit for "it would have been cheaper to lay fiber". I'd heartily recommend giving infra-red FSO a go, no Fresnel zone and it's essentially bridged ethernet - no funky routing required, though I would still set up OSPF or similar with it, to fail back to a slower link such as the RONJA.
