Re: Installing 1000 Series AP's in a dense environment
It would be tricky for 802.11g/b, because only three of the channels are "non-overlapping."
For 35x35, you could probably cover it with only one AP (get it up high to keep line of sight), maybe two in opposing corners ... four is serious overkill in most environments for a room that size.
If you went with two APs, and tweak thepower to the minimum necesary, then you can alternate the odd channel in alternate rooms (i.e., room 1:CH1 & 11, room 2: CH 6 and 1 (with the channel one units farthest apart), room 3: channel 6 and 11 (with the CH 11 units farthest apart .... something like that.
If you can get by with one unit active per room, then every third room would have the same channel assignment.
Have you done a site survey yet? Do you know for sure you need multiple units for coverage? Is the traffic level really going to be high enough to need multiple APs?
Even with fairly heavy traffic, the APs should be able to handle ~15 clients.
If you are / can use 802.11a, then it's not an issue, there's many more non-overlapping channels.
