- High Capacity Data Radio
High Capacity Data Radio (HCDR) is a development of the
NTDRfor the UK Government as a part of the Bowman Communication System. [citeweb|title=Bowman Hits the Mark|url=http://www.afcea.org/signal/articles/templates/SIGNAL_Article_Template.asp?articleid=503&zoneid=111 SIGNAL Magazine|publisher=afcea.org|accessdate=2008-02-20] It is a secure wideband 225 - 450 MHz UHFradio system that provides a self managing IP based Internet backbonecapability without the need for other infrastructure communications (mobile phone, fixed communications).
There is also an Export version that incorporates AES encryption rather and UK Government Type 1
Crypto. The radio offers a link throughput(terminal to terminal) of 500 kbit/s. A deployment of 200+ HCDR equipped military vehicles can automatically configure and self manage into a fully connected autonomous mesh networkintercommunicating using MANET protocols. The radio is an IPv4compliant 3 port routerhaving a radio port, Ethernetport and PPP serial port. The 20 watt radio has adaptive transmit power and adaptive forward error correctionand can optimally achieve ground ranges up to 15 km with omni-directional antennas. A maritime version allows radio LANoperation within flotillas of naval ships up to 20 km apart. The radio features coded modulationwith internal wide band or narrow band radio data modems.
