SAN RAMON, Calif.-US Wireless Corp. announced it has successfully completed testing its wireless E-911 caller location product, which exceeded the 125-meter range required by a 1996 Federal Communications Commission mandate.
RadioCamera is a Pentium- and Windows NT-based hybrid geolocation system that analyzes the radio pattern or “fingerprint” generated by a caller, including the timing and direction of the pattern. It is designed for installation in cellular, personal communications services and enhanced specialized mobile radio base stations.
RadioCamera product tests were conducted in downtown Oakland, and showed the product has overcome the main hurdles of rough multipath and a lack of line of sight in a high-rise metropolitan setting, thus eliminating the need for triangulation solutions. The company said it expects to deploy commercial quantities of RadioCamera by mid-1998.
