Application Introduction
Mainly transfer way: UAV~Car control station~ Control center~Internet to different city control center.
UAV assemble mini devices, transfer air live video signal to the communications station, or a local command centre. Local display monitor, storage command center can direct send the audio and video to real-time monitoring, dispatch. Other video way directly through the metropolitan area network or Wan transfers to the provinces and command center; to access PC browsing management, videos and so on.
COFDM is a great combination of encoding technology and OFDM modulation, which can be widely used and still with great potential in high speed mobile transmission systems as well as many other wireless transmission system applications for UAV, Border Patrol, military administration, Land Surveying, Police Defense or National Public Security, etc.
Because of its multi-carrier and other technical features, COFDM equipment with "non-line-of-sight", "diffraction" transmission advantages in urban areas, mountains, buildings and other inside and outside can not be blocked and the environment, the device can achieve stable video transmission, it is not affected by the environment. The transmitter and receiver ends generally use the omni antenna, so it is not necessary to check the location and orientation of the transmitter and receiver video transmission, video and audio the transmitter and the receiver can be freely operated according to the situation of the scene and the requirements of the director / director. The system is simple, reliable, and flexible.
