Crypto . The radio offers a linkthroughput (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 autonomousmesh network intercommunicating using MANET protocols. The radio is anIPv4 compliant 3 portrouter having a radio port,Ethernet port and PPP serial port. The 20 watt radio has adaptive transmit power and adaptiveforward error correction and can optimally achieve ground ranges up to 15 km with omni-directional antennas. A maritime version allows radioLAN operation within flotillas of naval ships up to 20 km apart. The radio features codedmodulation with internal wide band or narrow band radio datamodem s.References
