portable video transmitter AES128 Bits

Application:

  1. Shortwave communication
  2. Audio video (data) signal transmission
  3. Wireless range extender/ NLOS radio relay station

COFDM Technique Advantages

  1. 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.
  2. 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.
  3. 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...

Warranty

  1. Twelve months free warranty for equipment
  2. Three months for components
  3. Replcaement parts will be charged after one year
 
Product Description

DS-HDT20W is a new arrival digital wireless video audio transmitter which adopts the latest technologies of COFDM modulation and H.264 image compression that enables good NLOS (Non line-of -sight) transmission with DVD quality video. The transmitter is compact size with strong power amplifier for longer-range transmission. Good heat resistant with two cooling fans. Be safety with AES128 bits. It works well in fast-moving transmission.
