I've setup a fairly large wireless system. The event was at a conference for about 10K of people. I the test setup went well at my work location. It did not perform well at the event. Later, I found out that human bodies absorb signals. You might want to read up on that.

In many cases it's been clear that the person setting things up did not understand the effects of many computers in a small area.. Well, I now have a chance to show that I can do a better job. I believe I have a good handle on managing the RF side of things (set the access points to low power, use directional antennas to get coverage of the rooms without overlapping other access points, I have a wifi spectrum analyser to be able to measure coverage and the effect of the walls, etc) However, I can't think of anything particularly special on the IP side of things that I need to do. I can rate limit individual connections, use something like packetfence to watch for machines that look like they are infected and try and isolate them. I can police the vendor area with the scanner and ask booths that bring up their own access points to disable them (a major problem in past years) The access points available are a combination of 3com 7760 and WRT54GL (changing the firmware on the WRT APs is an option), I may buy a couple more, possibly picking up a couple N capible devices (not for the speed, but for the extra channels to try and releive the RF congestion) Should I try and put smarts in the APs? or just let them be a flat net with one SSID and do everything at the gateway/DHCP server? So what am I not thinking of?
