LAS VEGAS--(BUSINESS WIRE)--March 22, 2000

- Expands Channel Capacity up to Four Times -

- Provides Wireless Internet Access -

- Open Architecture for Voice and Data Mobile Applications -

At the International Wireless Communications Expo 2000 (IWCE 2000), ElectroCom Systems, Inc. today announced INVADR(TM), its wireless IP voice and data networking solution for the mobile communications market. Recognizing the premium value of radio frequency spectrum, ElectroCom has developed the INVADR system. The new system utilizes ElectroCom's patented Intelligent Diversity Reception(TM) technology combined with VoIP to provide a highly reliable open architecture for IP voice and data communications.

INVADR is a plug-and-play system that is both cost-effective and reliable as a primary communications system, an overlay for expanded capacity or redundancy, or as an analog trunk replacement. INVADR permits near error-free, two-way transmission of high-quality digital voice and high-speed digital data as well as access to the Internet, regardless of vehicle speed.

The system's open architecture simplifies integration with existing mobile communications systems, LANs, WANs, and the Internet. INVADR significantly improves the overall performance of a wireless network while improving its effective bandwidth, expanding the channel capacity of new or existing infrastructures up to four times. INVADR also combines advanced bit interleaving with forward error correction (FEC) to further improve performance.

"INVADR provides ElectroCom's customer base with a seamless migration path to the next generation of IP voice and data networking," according to Phil Madden, ElectroCom's director of marketing and sales. "We recognize that bandwidth is precious, so we employed the most advanced technologies available to create the INVADR solution."

"Our design goal was to offer a system with a low cost of ownership," said Joe Leonardi, chairman and CEO of ElectroCom. "INVADR's plug-and-play design ensures ease of installation and maintenance making the system extremely affordable."

ElectroCom is targeting the mobile communications markets within the Utility, Transportation, Government, and Public Safety sectors as well as SMRs and others needing to optimize valuable bandwidth. With the INVADR system, mobile communications operations can use the Internet to provide access to their mobile IP voice and data system without installing costly microwave links, WANs, or leasing DDS lines. Additionally, INVADR's open architecture opens the door to a wide range of mobile computer and software applications.
