Ad Hoc Network for Real-Time Audio and Video Transmission in Urban Environments

MV43 Vehicle Mesh Radio Specifications-v1.0_compre...

Introduction:

The vehicle mountable wireless video transmitter is the ideal solution for establishing rugged wireless video links in all environments including high-speed motion and urban environments. Especially, the latest technologies of COFDM modulation and MPEG-2/MPEG-4 video compression ensure high quality of NLOS (non line-of-sight) transmission. This system is high-powered and can realize longer transmission range with stable, real-time and high definition images. This product can be mounted in a car or helicopter to transmit real-time audio and video to the commanding center.

Features:

• 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;

Application:

The fleet marching vehicles are equipped with the deployment of wireless MESH vehicle-mounted stations to support dynamic networking in the fleet marching, and the network topology changes quickly when the vehicles enter and exit randomly and the formation keeps changing, without being affected by the constraints of vehicle formation changes, and the workshops can still maintain normal communication. At the same time, the command vehicle node can monitor the video of other vehicles in the vehicle, the vehicle and the road conditions, and can retrieve the vehicle Any video of the fleet can be transferred back to the remote command center through the moving communication satellite system.
