I'd like to employ FreeBSD as much as is feasible. This there are LOT of wireless bridges that can do if proper antennas are used. depending of where you are it may be not legal (output power*antenna gain can't be >100mW), like in EU (but nobody usually cares and controls), in US it is legal. Do not use any "afterburners" giving power in watt range. Normal 30-100mW output are OK. Example: Smartbridges 2.4Ghz WiFi radios (they are built to be used externally)+25dB grid antennas - worked at about real 4Mbit/s in 24km over the sea with large operating margin. It was 11Mbps only radios. But there are lot of method to do this. i think something like 50km is achievable. Just use one old rule - 1$ for radio, 1000$ for antenna :)
