It seems that, at least in NYC, hotspots should be replaced with hot-zones, meaning coordinated coverage of an area as Robin-David Hammond pointed out, thus reducing frequency clutter. --- Hans Zaunere President, New York PHP http://www.nyphp.com +1 212 213 1131 -- NYCwireless - http://www.nycwireless.net/ Un/Subscribe: http://lists.nycwireless.net/mailman/listinfo/nycwireless/ Archives: http://lists.nycwireless.net/pipermail/nycwireless/

I've already locked my AP down, based on MAC filtering - so I am the only one on my AP. Prior to locking it down, there would be 10 peer-to-peer clients using my AP within an hour. I guess they really like open APs down here in the LES :) So my other question is this: would adding encryption reduce interference at all? It seems like it wouldn't have a direct effect, but frankly I'm not sure.

Re: [nycwireless] Too Many Aps - Interference
Hi Hans, >From my personal experience I could recommend you to use any 802.11a ap or wireless router and adapter. Since they work on 5GHz and usually have low range (but still good for my whole apartment) they are not succeptable to 2.4GHz interference. They are also not interferring with 2.4GHz wireless phones and the speed decrese of 802.11a (with theoretical bandwith of 54Mbps) is probably just slightly slower in reality than 802.11g (that have theoretical bandwith of 108Mbps). Which is also only going to affect your computer to computer connection since your internet connection is well below any wireless setup available bandwith. 802.11a also has more nonoverlapping channels so that more computers can be connected without dropping connections (I have 11 computers connected in my office and they all work just fine). You could also buy dual band tri mode (802.11a, b, g) pc card for your notebook so that you can connect with 802.11a at your home and with 802.11b, g at your office of any public hot spot.
