GRX-8000 is the latest generation NATO Band IV, Dual Mode - High Capacity (HC) mode and Freq. Hopping (FH) mode line-of-sight broadband radio relay system developed by Elbit Systems. Designed to meet present and future tactical communications requirements ,the software-defined radio relay system supports latest IP and legacy communications protocols (G703, EUROCOM and others). The GRX-8000 is Jamming Resistant ECCM RR, enabling interference-free communications. The radio relay systems are battle proven and in use with the Israel Defense Forces and other armed forces around the globe.
High-Capacity – The GRX-8000 is capable of multi-mode, high-speed data transmission. The GRX-8000 In the NATO Band IV (4400 to 5000MHz) frequency range radio link provides data transmission capacity up to 100Mbps. Aggregated data rate is 200 Mbps (100 up + 100 down). The radio also has an extremely high system gain, supporting long distances at line-of-site conditions.
Frequency Hopping – GRX-8000 is capable of Synchronous Full Band Fast Frequency Hopping with coverage of total 600 MHz in NATO Band 4. The GRX-800 has an option to work in a Point-to-3Points configuration.
Multi-interface – The GRX-8000 incorporates a built-in sophisticated multiplexer supporting a wide variety of services ranging from traditional telephony to broadband multimedia for the very latest C4I applications. Its versatility allows the radio to multiplex IP data streams and serial trunk data at different rates simultaneously on the same link. The GRX-8000 includes a wide range of interfaces including Ethernet LAN / IP 100Base-TX ,G.703 E1 (2Mbps,).
Enhanced performance – The GRX-8000s’ high sensitivity, combined with its robust modulation schemes, provides very high link availability. Digital modulation with exceptional signal purity enables operation at congested radio relay nodes.
