Mobile Digital Wireless Transmitter Introduction:

This is an exclusive design COFDM émetteur et le récepteur. Has a character of low power, and a 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 (multiplexage par répartition orthogonale de la fréquence codée) modulation with 4 channel receiver, provide a high quality of picture in revolution 720*576, with short latency.

This specially designed system is for UAV long-range distance transmission, it is also popular to use in other fields for live broadcast video audio transmission.
