Abstract:
1. A computer-implemented method in a controller of a wireless communication network to deploy multiple access points on multiple communication channels to optimize for optimizing a coverage area while minimizing interference, the method comprising the steps of: collecting RSSI (received signal strength indicator) values for each station heard from each of a plurality of access points; assigning a subset of the plurality of access points to a first communication channel, comprising: determining a best access point per station based on the best access point having a highest RSSI value heard from the station; determining a second best access point per station based on the second best access point having a second highest RSSI value heard from the station; calculating an RSSI difference at each best access point between the highest RSSI value and the second highest RSSI value at a second best access point for each station; identifying a highest RSSI difference for each access point; and assigning access points with the RSSI difference above a predetermined threshold to a current communication channel, wherein the RSSI threshold indicates a lack of redundancy in coverage; assigning a second subset of access points with the RSSI difference below the predetermined threshold to at least a second communication channel, wherein the RSSI difference below the predetermined threshold indicates redundancy in coverage; and sending messages to the plurality of access points with channel assignments; and handing-off a station from an first access point on the first communication channel to a second access point on the second communication channel without requiring reconfiguration to the second access point by the station other than changing channels.
