Methods, apparatuses and systems directed to refreshing signal information
in an infrastructure wireless node location mechanism. The wireless node
location mechanism selectively terminates connections with wireless
clients to refresh signal strength information used to compute an
estimated location for the wireless clients. The wireless node location
mechanism terminates the connection between a WLAN and a given wireless
node, causing in typical WLAN protocol implementations, the mobile
station to transmit frames or packets on all available operating channels
in a given band. This allows access points and other WLAN elements,
operating on different frequency channels, to detect frames transmitted
by the mobile station and provide refreshed signal strength information
to a wireless node location mechanism.
