Abstract: A multi-standard indoor mobile radio access network having a centralized device is provided. In one embodiment of the present invention, once an emergency (e.g., 911, etc.) call has been place by a wireless device, an application operating on the device transmits a notification signal to the centralized device (e.g., via a radio head, etc.). In response thereto, the centralized device transmits location information of the wireless device to an emergency responder via a wireless service provider, where the location information is transmitted separately from the emergency call itself.

Abstract: A multi-standard indoor mobile radio access network having a centralized device is provided. In one embodiment of the present invention, a centralized device is configured to transmit a wake-up signal to a wireless device once the wireless device has entered a service area, wherein the wake-up signal triggers the downloading and/or opening of an application on the wireless device configured to determine whether a 911 call has been made. If a 911 call has been made, the application transmits a notification signal to the centralized device. In response thereto, the centralized device transmit location information of the wireless device to an emergency responder. The centralized device also transmits a “ping” to the wireless device during predetermined periods of time in order to keep the application open and/or installed on the wireless device.

Abstract: A multi-standard mobile radio access network for a building having a plurality of radio heads in communication with a centralized device is provided. In one embodiment of the present invention, each radio head is configured to transmit a plurality of test signals and to receive and measure reflections of the same (e.g., off of walls, ceilings, floors, etc.). Data associated with the test signals and the reflections (e.g., radio head IDs, transmittal and reception power levels, transmittal and reception times, angles of arrival, etc.) are then provided to the centralized device, where they are used to determine an RF power level for each radio head that minimizes interference with other radio heads and x-axis, y-axis, and/or z-axis locations of each radio head within the building.

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.
