High-capacity data radio
High-capacity data radio is a development of the Near-Term Digital Radio for the UK government as a part of the Bowman communication system. It is a secure wideband 225–450 MHz UHF radio system that provides a self-managing IP-based Internet backbone capability without the need for other infrastructure communications.
There is also an export version that incorporates Advanced Encryption Standard encryption rather than UK Government Type 1 Crypto. The radio offers a link throughput of 500 kbit/s. A deployment of over 200 HCDR-equipped military vehicles can automatically configure and self manage into a fully connected autonomous mesh network intercommunicating using mobile ad hoc network protocols. The radio is an IPv4-compliant three-port router having a radio port, Ethernet port and PPP serial port. The 20-watt radio has adaptive transmit power and adaptive forward error correction and can optimally achieve ground ranges up to 15 km with omnidirectional antennas. A maritime version allows radio LAN operation within flotillas of naval ships up to 20 km apart. The radio features coded modulation with internal wide-band or narrow band radio data modems.
