Abstract
A multi-standard indoor mobile radio access network is provided. Preferred embodiments of the present invention operate in accordance with a plurality of radio heads and at least one gateway/router. In one embodiment of the present invention, each radio head is configured to use a signal received from a wireless device to detect a corresponding service provider. Each radio is also configured to detect a power level of the signal, as received. Data is then communicated to the gateway/router, including at least radio head identification numbers, z-axis information (e.g., as stored in each radio head, etc.), the channels used, service provider identifiers, and power levels (e.g., as received by each radio head). The gateway/router is then configured to use at least the power levels and z-axis information provided by the plurality of radio heads to determine a location (e.g., z-axis location, or floor) of the wireless device.
