Long range wireless digital cofdm video transmitter and receiver is a digital NLOS or LOS remote HD COFDM wireless video transmitter with HD COFDM receiver. Wireless digital COFDM video transmitter and receiver SG-HD25 transmits data,including audio video, over a NLOS long range.
Digital Video Transmitter and Receiver is with the core technology 4th generation mobile communication COFDM module and low delay full hd 1080P technique.COFDM video transmitter can transmit high quality and stable image under the condition of fast moving or many buildings as obstacles (NLOS) with carrier velocity greater than 450 km / h.
this is a new COFDM digital transmitter receiver with Frequency-division duplexing (FDD) technology, designed with dual-mode RF transceiver system which operate at different carrier frequencies ideal for long range communication in network solution. The FDD technique uses different frequency bands for video radio sending and receiving with no interference.
