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 :)
