How many clients?

[tom at ceisystems.com]

Hello again,

	So, HostAP seems to be limited to somewhere around 15 STAs
(client devices).  This makes me think of a question.  Why can an
Orinoco (Proxim) 2500 AP handle hundreds of users, and HostAP can only
handle 15?  Again, I understand that 11Mbit/sec divided by 100 users is
only 112.64Kbps, but you will never see 100 _simultaneously_ active
users.

	Another thing I was looking at was the code for the HostAPd
system.  Would it not be faster, and more efficient to define a
large(ish) buffer for functions like `handle_read()` to drop data into
instead of defining variables every time those functions are called?
Then, you would only have to pass the address in the buffer between
functinons.  Anyway, just a thought.

Thanks all!
Thomas Cameron

For more users, I'd wager, than a nominal 11Mbits/sec link could happily

support. :-)
