Abstract:
1. A system for granting access, comprising: a mobile communications device comprising a cellular communications network transceiver, a first short range wireless transceiver, a processor and a memory, the memory containing instructions that, when executed by the processor, cause the first short range wireless transceiver to transmit a short range signal containing an identifier of the mobile communications device; a hands-free voice communications device comprising a second short range wireless transceiver, a processor and a memory, the memory containing instructions that, when executed by the processor, cause the second short range wireless transceiver to transmit and receive voice communications between the mobile communications device and the hands-free communications device; a detection device comprising a third short range wireless transceiver, a wireless local area network transceiver, a processor and a memory, the memory containing instructions that, when executed by the processor, cause the third short range wireless transceiver to receive the short range signal from the first short range wireless transceiver of the mobile communications device, and further cause the wireless local area network transceiver to transmit to a local area network, in response to receiving the short range signal, a message containing information on a signal strength of the short range signal as received by the detection device, an identifier of the detection device and the identifier of the mobile communications device; a device manager in the local area network comprising a processor and a memory, the memory containing instructions that, when executed by the processor, cause the processor to receive transmitted data from the detection device including the identifier of the mobile communications device, the identifier of the detection device, and the information on the signal strength of the short range signal as received by the detection device, and to perform a detection task; wherein the detection task includes determining a location of the mobile communications device using the transmitted data, determining a location of a second mobile communication device using second transmitted data, and granting to a user of the mobile communications device access to a physical area based on proximities of both the mobile communications device and the second mobile communication device to the detection device.
