BEACHWOOD, OHIO — Verizon Wireless, the nation's largest wireless carrier, and Allen Telecom Inc. (NYSE: ALN) announced today the successful completion of a large-scale CDMA field trial of Allen Telecom's Geometrix(TM) E911 Wireless Location Solution. Simultaneously, Allen announced high volume production of Geometrix systems beginning the fourth quarter of 2000 to meet anticipated carrier demand.

Verizon Wireless supervised and conducted the Geometrix trial, utilizing the standardized CDMA Development Group (CDG) wireless E911 verification test plan. Geometrix location system equipment was installed in Verizon Wireless base station cellular sites to cover a land area of over 1,000 square kilometers in and around Lexington, Kentucky. Verizon Wireless conducted more than 4,000 tests in 60 different calling scenarios covering virtually any conceivable emergency calling condition, including inside structures of various composition and moving and stationary vehicles. Trial tests and measurements included urban, suburban, and rural environments. All test calls were made from standard commercially available handsets. The trial area is representative of numerous wireless markets in the United States.

Allen Telecom officials said they were delighted that the positive results of the Verizon Wireless testing were consistent with other trials verifying that the Geometrix system meets FCC Phase II requirements for wireless E911 caller location accuracy.

The Phase II FCC requirements go into effect in 2001, and wireless carriers must inform the FCC as to their location technology choice by November 9 of this year.

Allen Telecom's Grayson Wireless division designs, builds, and markets the Geometrix system, a state-of-the-art, scalable, cost-effective, network overlay solution intended to allow carriers to meet the FCC's stringent requirements for wireless E911 caller location. Geometrix, which works with TDMA, AMPS, and iDEN wireless air interfaces as well as CDMA, supports the vast majority of wireless phones in use in the United States. Geometrix can also provide caller-locating support for a wide variety of location-based value-added services.
