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

I would be concerned about over-subscribing the Access Point. Any one
bridge
can only associate with one AP, and bandwidth is limited. Remember that
Wifi
is inherently a shared medium, and even 802.11g has limited bandwidth
compared to a switched, wired network. How many terminals you could
support
would depend on many things, like what other uses are being made of the
Wifi
net, how many APs are in use per unit area etc. With diskless terminals,
the
Sun marketing catchphrase "The network *is* the computer" is even more
true:
you are booting and mounting filesystems (NFS) over the net as well as
running X for your applications. If the net becomes congested, it will not
be
a pleasant experience for your users.
With 802.11g you can only have 3 non-overlapping channels within the same
coverage area. 802.11a has 12 non-overlapping channels, but I don't know
of
any 802.11a bridges (some APs can be used as bridges though). This limits
the
number of Wifi clients you can have within a limited area.
So, plan you Wifi net carefully and overprovision if you can. A good
resource
for Wifi planning and deployment is:
