HDMI / Composite Video UAV LOS NLOS Long Range Wireless Transmitter 20KM 110g Lightweight
LinkAV was founded in 2005 to provide wireless microwave products for video audio and data transmission based on COFDM/TDDOFDM/MESH/4G technology.
The COFDM with narrow bandwidth (2M-8MHz adjustable) and strong anti-multipath interference ability, different with analog and conventional modulation techniques, We are special for high-speed and real-time high-quality non-line-of-sight images transmission, particularly suitable for using under complex environments.
H.264 standard video coding, 1080P high-definition,clear picture quality, bright colors, smooth image characteristics for high reliable video transmission.
Our wireless video transmission equipment are widely used in government surveillances, law enforcement, UAV &UGV ,broadcasting, security, civil defense, fire, emergency rescue departments,forest fire prevention, transportation, customs, railways, mining, electricity, finance and so on.
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.
