TruePosition Selected by T-Mobile USA for GSM E911 Location Solution

TruePosition's Finder™ U-TDOA Location Solution Provides High Accuracy For Anyphone, AnywhereSM

Bellevue, WA and King of Prussia, PA, July 23, 2003 - T-Mobile USA, Inc. and TruePosition, Inc., a leading provider of location-based technologies, today announced a multi-year agreement to provide TruePosition's enhanced 911 solution to the T-Mobile national wireless network. The T-Mobile USA agreement will bring TruePosition's E911 services to a significant number of wireless users in the United States.

T-Mobile will be deploying TruePosition's Finder™ technology as part of its commitment to meeting the Federal Communication Commission's (FCC) Enhanced 911 (E911) Phase II mandate. The FCC requires all wireless carriers to provide designated public safety agencies with location information for 911 calls. For carriers using network-based technologies, such as TruePosition's, the FCC E911 Phase II mandate calls for wireless carriers to provide accuracy data to 100 meters for 67 percent of calls and 300 meters for 95 percent of calls.

"T-Mobile's agreement with TruePosition is an important step forward in the deployment of E911 location technology for GSM networks. We look forward to working with TruePosition on the rapid deployment of Uplink-Time Difference of Arrival (U-TDOA), and its advanced accuracy abilities, to local public safety agencies that have requested E911 Phase II," said John Pottle, Director, National Location and Emergency Services for T-Mobile.

T-Mobile operates an all-digital, national wireless network based on the globally dominant GSM (Global System for Mobile Communications) technology. TruePosition's E911 solution will provide T-Mobile customers the ability to be located with greater accuracy in accordance with the FCC's E911 Phase II guidelines and will be available nationally based on local public safety agency's requests.

"We are pleased to partner with T-Mobile to provide wireless location solutions to millions of additional wireless users across the country. Anyphone, AnywhereSM. That's our motto. TruePosition's network-based technology works with existing handsets in any environment," said Kent Sander, Chief Operating Officer and President of TruePosition, Inc.

"TruePosition continues to be a leader in the deployment of location technologies in support of the E911 mandate. Our Finder system offers the most comprehensive solution for wireless carriers across the country. The company remains committed to continuous innovation to respond to market needs in all types of environments, producing high accuracy results in urban, rural and suburban markets.

TruePosition's location solution is compatible with all air-interfaces and with all existing and future wireless phones," said Mr. Sander.
