Product Details

50km Video And Audio UAV COFDM HD Video Wireless transmits over 100km LOS and 1km to 3km nlos long range audio, video and images.

50km Video And Audio UAV COFDM HD Video Wireless is with COFDM modulation, H.264 mpeg-4video compression and AES encryption .

HD SDI Video input can be added, so that it can be made as a high definition (HD) COFDM wireless video transmitter.

50km Video And Audio UAV COFDM HD Video Wireless is used for long range audio, video transmission, live broadcast and drone video shooting / recording.

COFDM Technique Advantages

Strong interference:COFDM wireless transmitter is effectively against the multipath interference of signal waveform with the COFDM modulation. When the frequency selective fading occurs due to multipath transmission in the channel, only the subcarriers in the band depression and the signal carried by them are affected. The other subcarriers are not affected. Therefore, the overall bit error rate of the system is lower.
Anti-multipath fading: COFDM wireless audio video transmitter is effectively against the interference with the multi-carrier technique (COFDM). Compared to the single carrier, multi-carrier inherently resistant to time delay and has strong multipath capability. With joint coding of subcarriers & frequency diversity of the channel, the system’s performance is improved. Therefore, COFDM wireless system is suitable for multi-path environment and fading channel high-speed audio video data transmission.
LOS & NLOS operation: with strong penetration, strong diffraction & strong anti-interference, COFDM wireless system is suitable for high-speed mobile wireless transmission in NLOS &LOS operation without servo stability control assistance, such as on UAV to mobile vehicle, uav to groun station, UAV to vessle...
