In the rescue of major urban disasters and geological disasters, emergency communication, as an important part of the construction of emergency system, is becoming increasingly important. Unexpected events generally have the characteristics of uncertain time and location, etc., and communication requirements usually include audio and video multimedia transmission, sensor data transmission, file transmission, location data transmission and other different types of services. For such application scenarios, we provide a set of emergency communication solutions that can realize in-route communication, field communication and field command based on wireless broadband ad-hoc network technology.
The system consists of MESH base station, MESH relay and hand-held MESH. From storage, transport, load carrying, use, etc., to realize the rapid communication support. After arrived at the scene, the system can quickly deployment in the wild, city buildings, signal shielding places. The communication coverage radius of the private network is no less than 5km, 2km and 800m, which integrates various communication networks and applications to meet the requirements of commanders to obtain on-site situation and give instructions at the first time.
NexFi wireless broadband ad-hoc network emergency communication system can meet the timeliness, safety, convenience and mobility, can be used to deal with emergency rescue and disaster relief, the group unexpected incidents, counter-terrorism and other emergencies, effectively protect the emergency command communication on the scene.
