With 200m2 without barriers wireless go easy,
but bandwidth is complicated factor.
basic router 802.11g, (54) does not give good performance for my taste.
you need a really good. but you need a really good wifi-pci with a good
antena too.
cables and a switch works better for now.
may be a wifi N, works better, but its still expensive.

Well... the area is about 200m2 and is without barriers (its a big room)
where will be sit about 10 to 15 computers. The reason to use a wireless
network on this area is that there are no cable going to the switching area
so will be less espensive if we buy some APs... but the use of ltsp on this
area is inevitable.
So for what I understand are you saying that I must use 1 Bridge for every
3 computers OR 1 AP to every 3 computers connect to 1 bridge OR the each AP
can only have a good connection if I dont bind more them 3 bridges to it?
Because for what I was thinking before if we could connect some computers
(or all) to a bridge and them this bridge connected to the AP the problem
was solved... but now you let me some question
lol
