Verizon Wireless and U.S. Wireless Corporation Announce Successful Testing of CDMA Location System for Emergency 911 Caller Location

BEDMINSTER, New Jersey and SAN RAMON, Calif. — Verizon Wireless, the nation's largest wireless carrier, and U.S. Wireless Corporation (Nasdaq: USWC; Frankfurt: USP) today announced the successful completion of technical field trials in Baltimore of U.S. Wireless' cellular location technology, CDMA RadioCamera(TM) system.

The technology trial was conducted over a nine month period and encompassed a comprehensive four-stage field test program that included real-time processing of live AMPS and CDMA callers, covering substantially all of the downtown locations.

U.S. Wireless Chief Executive Officer Dr. Oliver Hilsenrath said, "The Baltimore trial results continue to validate our technology, illustrating that the RadioCamera(TM) system is one of the most accurate, real-time, wireless location systems available today. During trials the RadioCamera(TM) system consistently pinpointed the location of a wireless caller well within the requirements imposed by Phase II of the FCC E-911 Mandate."

Based on thousands of test calls, the location fixes were sufficiently accurate and timely, in both stationary and vehicular applications, to support advanced services including providing subscribers with turn-by-turn directions. Additionally, the system can continuously monitor a caller's location, if desired, a critical safety feature for some E-911 situations and other added value location sensitive services. Further improvements in location accuracy were demonstrated to be achievable with slight increases for call set-up times.

U.S. Wireless' RadioCamera(TM) system provides wireless carriers with continuous real-time location data needed to meet Phase II of the FCC E-911 mandate. Location information provided by the RadioCamera(TM) system also enables other services, including highway traffic control and planning, enhanced directory assistance, localized traffic condition reports and fleet location. The advanced CDMA location capability was enabled through a joint development and cross-licensing agreement between U.S. Wireless and Qualcomm, Inc.

"We were very pleased with the performance of U.S. Wireless' system," said Ted Hoffman, Vice President of Technology Development for Verizon Wireless. "We conducted our testing in Baltimore, a challenging urban radio propagation environment, and the results are encouraging. We will continue to work with U.S. Wireless and are evaluating the company's location offering."

Hilsenrath added, "We are excited to be working with Verizon Wireless, who has taken a leadership role in the CDMA carrier community, investing substantial resources in developing and evaluating location technologies that benefit the entire cellular community. We are very happy that this joint effort resulted in an effective and cost-efficient caller location solution that performs reliably in the most challenging conditions of the Baltimore metro area."

U.S. Wireless Corp. also noted that it will conduct an Operation Readiness trial in Washington, DC to help wireless carriers further evaluate the RadioCamera(TM) network, technology, scalability and commercial readiness to meet the FCC mandate.
