2.4GHz Radio Channel Overlapping

Dears,

I have 4 to 6 Autonomous APs running in each location (around 65 locations). All APs are configured to select the least congested channel. There many other APs running around our locations which are using the standard non overlapping channels. So our APs end up with some non standard overlapping channels. As shown in the attachment. We are using some game card readers. In a busy day the readers are running very slow. 

These readers work only in 2.4 Ghz. Can anybody suggest an optimum solution?

Statically assign CH1,6 and 11 for your APs

Channel selection depends on the frequencies that are permitted for a particular region. For example, the North American and ETSI 2.4 GHz band permits allocation of three non-overlapping channels (1, 6, and 11), while the 5 GHz band permits 23 channels.

The channels should be allocated to the coverage cells as follows:

  • Overlapping cells should use non-overlapping channels.
  • Where channels must be re-used in multiple cells, those cells should have minimal overlap with each other. Figure 3-13 shows this overlap pattern. In 802.11a/n/ac deployments, adjacent channels should be avoided as overlapping cells.
