How to configure roaming for Wireless LAN clients and how the roaming capabilities can be improved

Resolution

Roaming is a process controlled by the client adapter and is not defined by IEEE standards. This is also vendor-specific since each vendor has its own roaming algorithms. The roaming functionality is based on signal quality, not proximity. When a client's signal quality drops, it roams to another access point.

For the roaming process to occur adjacent access point's coverage cells should overlap to the maximum of 20 - 30 % above which it causes interference.
