1. A device for establishing real-time location information about a portable device, the device comprising:
a first communication interface operable to receive wireless communication transmissions from the portable device;
a second communication interface configured for communications with at least one fixed position device separate from the device;
wherein radio channel information is transmitted to the at least one fixed position device via the second communication interface;
wherein the radio channel information is received by the first communication interface from the portable device;
wherein the second communication interface is configured to obtain one or more device signal characteristics relating to a wireless communication received by the fixed position device from the portable device;
wherein the first communication interface includes a wireless interface;
wherein the second communication interface includes a wired interface; and
a controller operably coupled to the first communication interface and the second communication interface, wherein location information about the portable device is determined based on the one or more device signal characteristics.
