[TriLUG] wireless bridge?

[Greg Brown]

Beam through trees: no
Beam through trees with leaves: even more no
Beam through water: no
Beam through buildings: depends
	bricks: sorta
	wet bricks/block/cement: nope
Beam through roofs: yeah - depending on what they are made out of


Remember - you MUST have a line of sight connection to make a reliable 
point-to-point connection between two facilities using 802.11 and even 
though you might have a line of sight now it could change in the 
future.  Establishing a real link is harder than you might think at 
times.  My last wireless job I had to try to find a line of sight 
between a pier and a US military base in Korea.  Turns out a line of 
sight was impossible so I had to propose a bank shot off a hill.

Anyway, in the end neither one would work (the hill was 'owned' by 
Korea Telecom) so there was no wireless connection to be had.
