EFJohnson introduced this week the IP25 Trunked Infrastructure System, an encrypted end-to-end digital Project 25-compliant system that uses voice-over-IP technology to integrate repeaters, a digital dispatch console, system management, a secure key management facility for over-the-air re-keying of radios in the field and a portable PDA-based key loader. The system supports AES and DES-OFB encryptions for secure FIPS-compliant communications, according to the company.

One advantage of the system is that it does not require a gateway or network switch to link digital consoles and repeaters, said Michael E. Jalbert, chairman and chief executive officer of EFJohnson parent EFJ, Inc., in a statement. “The advantages for first responders are quick deployments, fewer network elements to own and maintain, and scalability,” he said.
