Wi-Spy and Channelyzer

Many wireless designers thought that the more access points are deployed, the better the signal strength or capacity they have. Well, most designers do think in this way, but most of the time they have omitted one very serious consideration, the overlapping co-channel interference, especially on the 2.4 GHz band.

(Remember the embarrassing Iphone 4 launch day moment, which saw a Wi-Fi connectivity blunder by Mr. Jobs.)

Fear no more :), you can try on Wi-Spy with Channelyzer software to analyze the co-channel interference at the deployed WLAN area.
