KENNEWICK, Wash.--(BUSINESS WIRE)--April 20, 2000

Electronic Systems Technology, Inc. (EST) (OTCBB:ELST), a manufacturer of wireless communications hardware, today announced the contract award for the ESTeem Mobile Data Computer (MDC) system for Police and Fire Departments of Gainesville, Texas.

The MDC system will provide an affordable wireless mobile data network allowing real-time wireless access to local and state databases for the City of Gainesville and selected portions of Cooke County.

"We are excited that this is the first installation to integrate both police and fire department vehicles into the same system at start-up," states Capt. Frederic Anderson (ret), EST's MDC Systems Manager. "We hope this is a trend that continues for future sites."

The ESTeem MDC system provides agencies an alternative to proprietary data networks such as CDPD, where agencies incur monthly service fees. The ESTeem MDC system allows agencies to establish a private Radio Area Network (RAN), free of monthly service fees, transmitting data at 19,200 bps, utilizing the 450 to 470 MHz UHF business radio spectrum.

The foundation of the ESTeem MDC system is the ESTeem Model 192 wireless modem. The Esteem Model 192 boasts a radio frequency (RF) data rate twice as fast as current technology, while adding a wireless infrared programming port for ease of diagnostics and maintenance. The narrow band, packet burst transceiver allows networking of 253 devices on a single frequency using the industry standard RS-232, RS-422, or RS-485 asynchronous, full duplex interfaces.
