Two Way Speaking COFDM Video Transmitter 5km NLOS Wireless AV Sender with Data
Introduction:
This is an exclusive design COFDM transmitter and receiver. Has a character of low power, small dimension on the transmitter, and we provide more adequate considerations to make it more intuitive and natural.Use H.264 coding format and COFDM (coded orthogonal frequency division multiplexing) modulation with 4 channel receiver, provide high quality of picture in resolution 1920*1080P, short latency.
This special designed system is for UAV long range distance transmission , it is also popular to use in other fields for live broadcast video audio transmission.
