On the first drop there were 30 AP on channel 6 (the channel being used) all at 54M and 6 with SSID "ietf". Its definitely a demanding environment. btw- I can't get you any more data in super busy air until next IETF in July. I'd be willing to work more closely with you to collect any data that you need if that helps. Curtis
