Digital Channel COFDM Wireless Video Transmitter For Quad Rotor / Six Rotor / Eight Rotor For UAV Traffic Street Shot

 

COFDM Video transmitter Anti-electromagnetic interference performance:
It has superior performance against frequency selective fading or narrow bandwidth interference and signal waveform interference. It has strong anti-fading ability, through each subcarrier joint coding. In single carrier system(digital microwave, spread spectrum system, etc), single decline or interference will result in all communication link failure. But in multiple carrier COFDM system, only a few subcarriers will be interfered What’s more, these sub-channel can adopt ECC to correct error, to guarantee the transmission low error rate.

COFDM Video transmitter Anti-multipath fading:
It can confront signal waveform interference effectively; suitable for multi-path environment and fading channel high-speed data transmission. When the frequency selective fading appear in the channel because of multi-path transmission, only the sub-carrier, which fell over the band depression, and the information carried will be affected. Other sub-carriers will not be affected. Thus, the system total error rate performance will be much better.

 

The C654 transmitter is a mini COFDM video transmitter from Wireless LinkAV, designed specifically for UAV/ Drones video transmission applications.

With proven LinkAV COFDM technology and H.264 encoder technology at its core, the C654 transmitter enables viewers high definition images ideal for establishing rugged wireless video links in all environments including mobile and urban environments.

The small size and ultra-low power consumption make the C654 transmitter ideal for UAV installations, enabling true long range HD quality transmission from these increasingly popular devices for the first time. Optional lightweight, low power consumption amplifiers are also available for even greater range capability.
