Irving, TX – August 14, 2009 – EF Johnson Technologies, Inc. (NASDAQ: EFJI) today introduced Hybrid IP25™, the first Project 25 compliant wide area conventional infrastructure system that will enable first responders to roam between trunked and conventional systems. Hybrid IP25 will be on display at the Association of Public-Safety Communications Officials annual conference and exposition, August 16 – 19 at the Las Vegas Convention Center.

“Our IP25 wide area conventional system is the first true hybrid network, in which first responders will be able to operate and interoperate between the conventional and trunked systems, eliminating the need for dispatchers to manually patch calls between the two systems,” said Michael Jalbert, president and chief executive officer of EF Johnson Technologies, Inc. “This hybrid radio system is based on Voice over Internet Protocol (VoIP) which enables it to gracefully scale to accommodate future expansions. Our Hybrid system is the most cost-effective way to provide wide area coverage and innovative features such as roaming and mobility, which are normally only found on trunked systems that cost millions of dollars more. The distributed architecture of our system makes it scalable and interoperable, so customers can add system users and know they will have excellent coverage.” Hybrid IP25 expands upon the Company’s commitment to both trunked and conventional infrastructure systems, Jalbert added.

Key features of this hybrid system will include:

• Seamless roaming between trunked and conventional systems, which eliminates the need for dispatchers to manually route calls
• Fully distributed switchless architecture that eliminates single point of failure
• Common network management and dispatch between trunked and conventional systems, substantially reducing capital expenses and operating costs
