Ultra-wideband geographic location system and method
First Claim
1. A method of reporting the geographic location of a wireless communications device, the method comprising steps of:
- emitting an emergency signal from the wireless communication device;
receiving the emergency signal at at least two access points, and transmitting at least two ultra-wideband signals in response, the ultra-wideband signals containing information about the geographic locations of the access points;
determining a geographic location of the wireless communication device using the geographic locations of the access points; and
transmitting the geographic location of the wireless communication device.

Abstract
A system, method and article of manufacture are provided for reporting a location of a wireless device. In one embodiment, an emergency signal is transmitted from the wireless device. The emergency signal is received by at least two access points. The two access points transmit at least two ultra-wideband signals in response, the ultra-wideband signals containing information about the geographic locations of the access points. The geographic location of the wireless device is determined using the geographic locations of the access points. The geographic location of the wireless device is then transmitted. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
