Posted: 29-Mar-2001 [Source: Wireless News Factor]

[The RadioCamera system uses a proprietary location pattern matching technology as opposed to a direct line of site method making it more effective in densely populated areas.]

by J.B. Houck -- "U.S. Wireless Corporation (Nasdaq: USWC - news) has received approval from the United States Patent and Trademark Office (USPTO) for patent claims covering its tracking of wireless devices via location pattern-matching technology. "The patent describes methods for determining the location of a wireless CDMA (code division multiple access) device based on patterns of radio frequency reflections, U.S. Wireless said. The frequency reflections are generated as a signal bounces off obstructions while traveling from a handset to a base station or receiving antenna.
