Claim:
An apparatus comprising: at least one antenna configured to send and receive signals; and at least one processor configured to send, receive, and process the signals sent and received by the at least one antenna, wherein the at least one processor is configured to cause the apparatus to: monitor, within a narrow evaluation region, for IEEE 802.11 beacon signals sent by a wireless device, if the IEEE 802.11 beacon signals are not received within the narrow evaluation region, monitor the IEEE 802.11 beacon signals within a wide evaluation region, if the IEEE 802.11 beacon signals are received within the wide evaluation region, reset the monitoring to the narrow evaluation region, and if the IEEE 802.11 beacon signals are not received within the narrow evaluation region after the IEEE 802.11 beacon signals were received within the wide evaluation region at least a predetermined number of times, the predetermined number being greater than one, accept the wide evaluation region.
