[RndTbl] Point to point wireless

[Kevin McGregor]

Where is a good place to order Buffalo wireless equipment? How
important is line-of-sight? Would it be reasonable to get a good
connection across 270 feet (~82m) from inside one house to inside
another, with trees and fences in the way? Two of the homes are 5.5
lots apart (across the backyard - no lane - and down five houses). I'd
rather get a better connection and not blanket the neighbourhood with
our signal if possible, which is why I'm wondering about a directional
antenna.
