> Making APs as low power and "local" as possible is good advice
^ Ignoring this advice is one of the biggest mistakes people make. They th=
ink "Oh, I'll just drown out the noise", but the problem is almost never ho=
w well the clients can see the AP - it's the AP seeing the clients. It's h=
ard to hear anyone talking when you're shouting! ;)
Low power, high AP density, and small channel widths are the way to go. Th=
e smaller channels keep theoretical bandwidth lower, but you end up with hi=
gher throughput in the end.
One other thing specific to the unifi's - they are meant to be ceiling or w=
allmounted. They transmit and receive in a cone. They *DO NOT* work well =
if you set them on a table pointed at the ceiling. I've already seen a hal=
f dozen deployments of them done this way, just slapped on tables, and it *=
does not work*. In one case, moving them from the tables to the walls resu=
lted in a 20x performance increase.
