Ultra-wideband geographic location system and method

A system for reporting the geographic location of a wireless communications device, comprising:

• logic for emitting an emergency signal from the wireless communication device;
• logic for 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;
• logic for determining a geographic location of the wireless communication device using the geographic locations of the access points;
• and
• logic for transmitting the geographic location of the wireless communication device.

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 an access point;
• transmitting an ultra-wideband signal from the access point to at least two ultra-wideband devices, requesting the ultra-wideband devices transmit their geographic locations;
• receiving the geographic locations of the ultra-wideband devices at the wireless communication device;
• determining a geographic location of the wireless communication device using the geographic locations of the ultra-wideband devices;
• and
• transmitting the geographic location of the wireless communication device.

A method of reporting the geographic location of a wireless communications device, the method comprising steps of:

• means for emitting an emergency signal from the wireless communication device;
• means for receiving the emergency signal at an access point;
• means for transmitting an ultra-wideband signal from the access point to at least two ultra-wideband devices, requesting the ultra-wideband devices transmit their geographic locations;

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 a fixed access point;
• transmitting the emergency signal to at least one other fixed access point,
• transmitting the geographic location of each fixed access point;
• determining a geographic location of the wireless communication device using the geographic locations of the fixed access points;
• and
• transmitting the geographic location of the wireless communication device.
