Abstract
A wireless local area network (LAN), and a method of operating the same, prevents unauthorized users from accessing the wireless LAN. A signal strength of a station attempting to access the wireless LAN is measured. If the signal strength is less than a predetermined threshold value, the system concludes that the station is outside of an authorized geographical area. Such a station attempting to establish a connection is characterized as an unauthorized station, and access to the wireless LAN is denied. The system may also periodically verify that authorized stations remain within the authorized geographical area. A station that has moved outside of the authorized geographical area can be notified or denied further access to the wireless LAN.
