Hi Steve.  Stephen and I and a few others were looking into building a  
"community wireless network" .. basically a way to lash together  
several users sharing a T1 or similar broadband wired access.  This is  
pretty sophisticated stuff, with Power Over Ethernet (POE), antennas,  
outside utility boxes with wireless routers and so on.

This is different than simply extending the range of a wireless base  
station, which is likely what you'd find workable.  I've not used a  
repeater, but as I understand it, most wireless base stations can be  
configured to be an intermediate bridge between a client and a base  
station.  The airport express is a small "wall wart" that does this  
rather nicely.  Google "Wireless repeater" for lots of hints.

As mentioned by others, better antennas can help too.  The sudden  
change is often due to foliage and similar environmental things.

Our earlier rigs had roof-top antennas aimed carefully at the land- 
line house which had an omni antenna.  The wireless community network  
was a WAN network, with an ethernet snaked into the house, and which  
also powered the roof-top basestation via POE.  Oddly enough, you'd  
need another wireless basestation if wireless LAN was desired inside  
the house!  Hard to grok.
