1. A method, used by a system including at least one server, at least one processor, at least one storage device, and at least one network interface, of identifying a location of a user of a wireless device within a physical named location comprising the acts of:

  • storing, in the at least one storage device of the system, information pertaining to;

    (i) a first positional coordinate within the physical named location associated with a first set of transmitter identification data that identifies a first Bluetooth radio transmitter as physically situated within the physical named location, and(ii) a second positional coordinate within the physical named location associated with a second set of transmitter identification data that identifies a second Bluetooth radio transmitter; and

    ,receiving, using the at least one network interface of the system via the Internet, a communication from the wireless device including at least a portion of the first set of transmitter identification data that is selected for inclusion in the communication based upon a relative signal strength reading associated with the first Bluetooth radio transmitter;

    determining, using at least one processor of the system that is configured to compare at least a portion of the stored information with at least a portion of the received communication, that the wireless device is, or was, physically located proximate to the first Bluetooth radio transmitter within the physical named location;

    transmitting the first and second positional coordinates to the wireless device via the Internet using the at least one network interface of the system; and

    ,receiving from the wireless device, using the at least one network interface of the system, a calculated position of the wireless device within the physical named location that is based upon the first and second positional coordinates and the relative signal strength readings of the first Bluetooth radio transmitter and the second Bluetooth radio transmitter.
