1. A device manager system for granting access, comprising:
- a detection device comprising a short range wireless transceiver, a first wireless local area network transceiver, a processor and a memory containing instructions that, when executed by the processor, cause the short range wireless transceiver to receive a short range radio signal transmitted by a mobile cellular voice communications device, the short range radio signal containing an identifier of the mobile cellular voice communications device, the instructions further causing the first wireless local area network transceiver to transmit via a local area network, in response to receiving the short range radio signal, a message containing information on a time difference of arrival of the short range radio signal as received by the detection device, an identifier of the detection device and the identifier of the mobile cellular voice communications device;
a device manager in the local area network comprising a second wireless local area network transceiver, a processor and a memory, the memory containing instructions that, when executed by the processor, cause the processor to receive the message via the second wireless local area network transceiver and to perform a detection task, the detection task comprising determining a location of the mobile cellular voice communications device using the information contained in the message, determining a location of a second mobile cellular voice communications device using a second message, and granting to a user of the mobile cellular voice communications device access to a physical area based on proximities of both the mobile cellular voice communications device and the second mobile cellular voice communications device to the detection device.

10. A method for granting access using a location of a mobile cellular voice communications device, comprising:
-
receiving, at a detection device, a short range wireless signal containing an identity of a first mobile cellular voice communications device, the short range wireless signal originating from a short range wireless transceiver of the first mobile cellular voice communications device; determining a proximity of the first mobile cellular voice communications device to the detection device based on a time difference of arrival of the short range signal; in response to receiving the short range signal, transmitting, by a wireless local area network transceiver of the detection device, a message containing the first mobile cellular voice communications device identity and the proximity of the first mobile cellular voice communications device to the detection device; transmitting from the detection device through the wireless local area network transceiver, a message containing a second mobile cellular voice communications device identity and a proximity of a second mobile cellular voice communications device to the detection device; and granting to a user of the first mobile cellular voice communications device access to a physical area based on the proximities to the detection device of both the first mobile cellular voice communications device and the second mobile cellular voice communications device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
