Channel Overlap Question

rx33328 · ‎11-07-2003

We are using Cisco 1200 AP's(802.11b). If I had an area where there is channel overlap, how would I know that it does exits? Is there certain errors to look at on the AP's? I don't see anything in the log to reflect that it could be occuring.

Try using the Radio Diagnosis tool from the Ap1200 config page. It should show you the noise (S/N) on each channel. Trun-off radio port on one of the APs( with the same channel) and check the noise and compare the difference in noise levels.

If there is a channel overlap the client commnunication (packets) would be affected and might be displayed in the client properties page on the AP1200s.

Hello,

the best way is to use e.g. AirSnort (or a SpectrumAnalyzor) and look for all used Channels in your neighborhood. If you see any other Channels the only way is for you : make use of directed antennas.

If you have overlapping Channels in your neighborhood

you can see on the ACU, frequently errors in the statistic menue.
