Abstract
A mesh network communication system includes a plurality of access points connected to a wireless local area network (WLAN) controller where at least one of the plurality access points is a detection access point (DAP) that received reverse link (RL) wireless wide area network (WWAN) signals transmitted from a multi-mode wireless communication device. Based on an intercepted RL WWAN signal, the DAP forwards reverse link (RL) information to the WLAN controller. Based on the RL information, the WLAN controller sends a device proximity message to the WWAN communication system where the device proximity message is based on the proximity of the multi-mode communication device to the mesh network communication network. One or more non-detection access points (NDAPs) of the plurality of access points are capable of providing WLAN service, and may also have the capability to receive RL WWAN signals, but do not send RL information to the WLAN controller.
