High-capacity data radio (HCDR) is a development of the Near-Term Digital Radio (NTDR) for the UK government as a part of the Bowman communication system.
[1] 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 (mobile phone, fixed communications).
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 (MANET) protocols.
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.
