BEDMINSTER, NJ — Verizon Wireless and TruePosition, Inc. today announced the successful completion of a field test of the TruePosition Wireless Location System (WLS) in mid-town Manhattan. Verizon Laboratories used the rigorous test plan published by the CDMA Development Group (CDG) to determine the performance of TruePosition's network-based location technology in a challenging urban canyon environment. The WLS demonstrated sub-100 meter location results in a variety of indoor, outdoor, pedestrian, and moving vehicle scenarios.

"This field test was conducted in the most difficult radio frequency environment in the country. Almost half of the test calls were made inside of multi-story buildings, which makes the results even more exciting," said Kent Sander, president of TruePosition. "We believe TruePosition is the first company to demonstrate compliance with the Federal Communications Commission's (FCC) E9-1-1 mandate with a system that is commercially available for both emergency services and commercial wireless location service providers."

Standard CDMA mobile phones were used to make more than 30,000 test calls by both Verizon Labs (formerly GTE Labs) and TruePosition in an area covered by 30 cell sites. A significant advantage of the WLS is the capability to locate existing phones. More than 43 million wireless calls to 9-1-1 are made annually from existing wireless phones. In addition to E9-1-1, the WLS is designed to enable a commercial wireless location service market estimated at several billion dollars.

"We were very pleased with the performance of TruePosition's system in this field test. TruePosition clearly met the expectations of Verizon Wireless," said Ted Hoffman, vice president of Technology Development for Verizon Wireless. "Manhattan proves to be a challenging environment for radio propagation and this trial serves as an important step as we begin preparations to meet the FCC E9-1-1 mandate. ."
