AP1200 and Least Congested Frequency

Hello Everyone,

Is it every a good idea to allow the APs to be set for "Least Congested Frequency"?   Especially in a hotel type environment?  There were some APs thrown up by another company without a site survey being done.  They choose to set all the APs to this setting for whatever reason.  Our wireless team is going in behind them to straighten this out but since I am still on my learning curve I thought I would ask here.  There are 4 APs on every other floor in an 8 story hotel.  Some are within 50-100 feet of each other.

Thanks in advance!  All replies rated

Hi Angel,

When you configure the AP, Cisco recommends that you disable the option to search for the least-congested channel. Cisco recommends that administrators manually set all RF channels according to the data gathered during the site survey and site survey verification steps. If you use the option to select the least-congested channel, the AP will change to a different channel every time its power is reset, thus leaving no predictability and negating the time and effort spent on the site survey.

The default channel setting for the AP radios is least congested. At startup, the AP scans for and selects the least-congested channel. For the most consistent performance after a site survey however, Cisco recommends that you assign a static channel setting for each AP.

It's too bad you can't replace the APs with 3500i/e.
