ABSTRACT:
A WLAN (108) includes a first access point (104) for providing wireless service within a first coverage area, a second access point (106) for providing wireless service within a second coverage area and programmed to transmit probe responses, and a wireless communications unit (102) located within the first coverage area and operating on the wireless service of the first access point (104). The communications unit (102) is programmed to monitor, or passively probe, for the probe responses, or is instructed by the first access point (104) on when to monitor for the probe responses, transmitted by the second access point (106). By executing such passive probing, the communications unit (102) may make handover decisions for switching between the wireless service of the first access point (104) to the wireless service of the second access point (106) based on access point data included in the probe responses.
