20km Long Range Digital Wireless Video Transmitter and Receiver with Low Latency
Real-time mbile wireless av transmitter Description:
DS-HDT20WG is a powerful COFDM wireless video audio transmitter designed from Ding Shen Technology, it's adopts the latest COFDM modulation and narrow bandwidth at its core, which is enable to transmit 1080P/I full HD video quality in fast moving and NLOS (non-line-of-sight) environment.
With 20 watt high RF power, DS-HDT20WG can easily to transmit 10~15km NLOS long distance wireless video and 1920*1080P high definition broadcast quality image in urban area; and 100km LOS from air to ground.
The frequency, RF power, video input, and the housing of the DS-HDT20WG cofdm video transmitter all can be designed and customized based on user's application and requirement.
