The handheld self-organizing mesh network radio is small in size, light in weight, and equipped with a removable lithium battery. It can be held in hand or carried on a individual soldier shoulder or back.Fast network access and automatic multi-hop relay can provide voice group calls, video backhaul, relay transmission and other multimedia communication services for individual soldiers, tactical teams and tactical police dogs, achieving efficient collaboration. It has both GPS and Beidou positioning functions, and also supports wifi coverage, and can cooperate with smart terminals with wifi functions for various communications. The system adopts the same frequency networking and multi-hop relay, and supports any network topology, such as point-to-point, point-to-multipoint, chain relay, mesh network and hybrid network topology. The self-organizing mesh network algorithm with strong robustness is embedded, and no central gateway is required. Any one of them can realize the self-organizing network function. In practical applications, mesh network design can be adopted without worrying about network disconnection. It can provide wireless broadband communication for emergency response, anti-terrorism and riot prevention, covert reconnaissance, special operations, disaster relief, daily patrol and other "peace and war" tasks in the first time. Transmission distance: more than 5km in open ground environment, 300~500m in blocked environment (depending on the blocking environment), and more than 20km from air to ground.
