800 people! Wow! I once went to Internet2/Joint Tech meeting and saw
similar sight, but that was about 400 people or so...
John, for that large lecture hall with 250 users, we plan to use Proxim
AP2000 with two radio
I would think you would be safe with 20-30
connections per access point. This could run into quite a bit of money, though
it might still be less costly than that number of ports on managed switches.

If it's a new design/construction I would most certainly wire the classrooms. First off, it's relatively cheap to pull wire and jack 400 locations in a new installation. Even if you don't use the wired connections, you'll have the terminal and most likely the locations for Wireless too.

We are in the process of installing access
point all over campus. We keep telling people that this is a compliment to wired
connections not a replacement.

Excellent message. We had all kinds of problems with users who
want wireless LAN technology but refuse to accept/realize/understand
that the technology is has limitations. Everything from privacy, sufficient
bandwidth for online exams, reserving AP and the associated RF space
for
Arnie - we have a new science building that is just
starting construction. We have two auditoriums with 250 seats each in the
design. The decision was made to pull cable to each seat; as convenient as
wireless is, it still has limitations related to host-to-access

We have been resisting the addition of Wireless to large
classrooms simply due to the user factor. How are you going
to communicate to hundredes of users which access point they
should
High density is a big challenge to wireless deployment. We are
currently facing the same issue. In one of our wireless projects, we
were told that there might be up to 250 simultaneous users ( Even
worse: Did I mention they are all Pocket PCs with wireless cards? ) in
one large lecture hall
I used to be very worried about high density until I started to attend
the IEEE meetings a few years ago where there is close to 800 engineers
with laptops downloading PDFs, PPTs and DOCs. Quite the sight! I wish
there was a way to take pictures but these aren't allowed at IEEE
meetings. Worth
Sean,

Pull 8 circuits and use 8 APs, do not use the 2 bays if you can:
when you use the 2 bays, radios have to be 10 lamdas away (about 1 meter
at 2.4 GHz) which will force you to use antennas...at the same time these
antennas will reach too far and create interferences (unless
John, Philippe, E.J. and all,
Thanks much for the advices!
I love this place!
a 3.5 dbi Omni-directional antenna 50 bucks
a pigtail for proxim radio card 20 bucks
a Proxim AP2000 b/g, 600 bucks
