General Dynamics C4 Systems and Lockheed Martin will advance to the next development phase of the Integrated Wireless Network — an IP-based VHF trunked system utilizing advanced encryption standards and built for law enforcement and other first responders — according to the Departments of Justice, Treasury and Homeland Security.

The companies will draft a design-and-implementation plan for a specific region of the country. Once the entire project is completed, the government agencies hope the network will serve as a secure wireless system for voice, data and multimedia applications for local, state and federal officers responding to incidents in the field.
