Cofdm Mesh Network Drone Radio for Uav Drone Video Data Transmission

Unmanned system self-grouping radio, small size, light weight, can be front-loading or back-loading, easy to install, especially suitable for unmanned aircraft, unmanned vehicles, unmanned boats, robots and other applications with lightweight networking needs. With fast access to the network and automatic multi-hop relay, it can be used with handheld man-portable systems, vehicle systems and peripheral base station network equipment to form an interconnected three-dimensional network and achieve efficient cooperation. Both: Beidou positioning function and also support wifi coverage, which can be used with wifi-enabled intelligent terminals for various communications. The system adopts the same frequency networking, multi-hop relay, and supports any network topology, such as point-to-point, point-to-multipoint, chain relay, mesh network and mixed network topology. It can provide wireless broadband communication for emergency response, anti-riot, rescue and disaster relief, daily patrol, etc. The transmission distance can be more than 10km on the ground in open environment, 300~1000m in blocking environment (depending on the blocking environment), and more than 30km from air to ground.

• Centerless networking: nodes have equal status, i.e. as terminal nodes, relay nodes or central nodes;
   

• Arbitrary structured networking: automatic identification of nodes to select the optimal route for bandwidth data;
   

• Security and confidentiality: AES128/256 support through layers of encryption such as working frequency, carrier bandwidth and scrambling code;
   

• Anti-interference and anti-destruction: COFDM, MIMO, ARQ and other technologies are used to improve data bandwidth and anti-interference performance;
   

• Flexible multi-node networking: automatic calculation of link routing and flexible networking based on channel quality, rate, BER and other indicators;
   

• All-IP network interoperability: support for data transmission, interconnection and interoperability of multiple systems, and real-time interaction of multimedia services;

Wireless Broadband Mesh Unmanned Device Communication System:

Through the unmanned system cluster, it is built into a huge information coverage network, while maintaining interconnection and interoperability among each other, and can collaborate to complete the assigned tasks in a certain formation according to the site situation. At the same time, it is equipped with wireless self-organizing network cluster communication, which is centerless, highly destructive and highly self-healing, and can be dynamically autonomous according to the site, and can quickly self-regulate to supplement the interrupted network once it encounters a failure or accident, so that the whole network system still maintains an efficient and orderly operation.
