[asterisk-users] long distance ethernet & Asterisk

[kaze0010 at umn.edu]

Light the fiber to get to that 2000ft mark, then use directional antennas 
to cover the last 2000 ft via wireless. If necessary, you could even use 
unlicensed 900 mhz gear that runs 802.11g speeds (search for the Ubiquiti 
SR9), http://www.wlanparts.com/c=*/product/SR9 has it for $149 when in 
stock.

Your best bet may be to try wireless the whole way and then try using the 
fiber if wireless isn't going to cut it. If you end up needing repeater 
stations, remember to factor in solar panel and battery costs sufficient to 
last the maximum number of sunless or minimal sun days.
