    Three people said they'd pick "A" but only two voted. Get back in here and do your duty! :x :wink:

    Close enough. The answer is A.

    When you co-locate several access points, you usually are trying to load balance and/or you are servicing a large number of WLAN users located pretty close together. Getting all of them to send their signals through one or even two APs would slow them down to a crawl. Using three within a few feet of each other will enable an office of WLAN users to navagate the network and maintain productive speeds. Of course, if they use the same channel for each of them, the interference will be just as bad as using only one AP. In the US. we are allowed to use channels 1 through 11. The only channels that completely do not overlap (that's not exactly true, but close enough) are 1, 6, and 11. Any channels that are closer will encounter some overlap and thus some interference. Needless to say, three APs all using Channel 1 will result in the greatest amount of interference.

    More tomorrow.
