The Mobile Relay Communication System (MRCS) is a rapidly deployable, trailer-mounted communications platform designed to deliver secure, reliable connectivity in demanding environments. Available in MRCS Light and MRCS Heavy configurations, it combines high-capacity line-of-sight microwave radios, MPU5 Mobile Ad Hoc Network (MANET) technology, and integrated perimeter security cameras to extend communications and enhance situational awareness. The lightweight system is optimized for rapid deployment and mobility, while the heavy-duty variant provides greater mast height, payload capacity, and endurance for extended missions. Built with hybrid power and rugged off-road capability, both platforms support military, border security, critical infrastructure, and emergency response operations.
