Use of third party ultra wideband devices to establish geo-positional data
First Claim
1. A method for determining a location of a wireless device, comprising:
- transmitting an initial request to wireless devices having known locations for positioning information for determining a location of a first wireless device having an undetermined location, wherein wireless devices having known locations that receive the initial request transmit positioning information to the first wireless device;
if positioning information from less than a sufficient number of wireless devices of known location is received by the first mobile wireless device, transmitting an additional request for responses from other wireless devices that may derive their own location from even more distant known-location wireless devices;
receiving responses to the request from one or more of these responding other wireless devices;
communicating with at least a portion of the responding other wireless devices to obtain information relating to the distance between the first wireless device and the at least a portion of the responding other wireless devices; and
estimating a location of the first wireless device using the information obtained from the at least a portion of the responding other wireless device and the positioning information received from the less than sufficient number of wireless devices having known locations.

Abstract
A system, method and article of manufacture are provided for determining a location of a wireless device in a wireless communication system. In general, an initial request is transmitted to wireless devices having known locations for positioning information so that a location can be determined for a first wireless device having an undetermined location. Those wireless devices with known locations that receive the initial request in turn transmit positioning information to the first wireless device. If positioning information from less than a sufficient number of wireless devices with known location is received by the first mobile wireless device, an additional request is then transmitted for responses from these responding other wireless devices. After responses to the request from one or more of these responding other wireless devices are received, communication then occurs with at least a portion of the responding wireless devices to obtain information relating to the distance between the first wireless device and the responding wireless devices it is communicating with. Next, a location of the first wireless device is estimated using the information obtained from these responding other wireless devices and the positioning information received from the wireless devices with known locations.
