COFDM wireless video  transmitter Applications:

This military backpack system is special for man-portable transmitter enter into the area of the incident to gather information and signal transmission when in the condition of heavy obstacles, such as many building barriers, severe electromagnetic interference, remote mountain town or other harsh environments, which cause command vehicle can’t directly reach the site and forced to parked in vicinity.



Why Use COFDM Technology:


COFDM that is encoded orthogonal frequency division multiplexing, is the world's most advanced and most development potential of the modulation technology. Its practical value is to support the

application of breakthrough line of sight restrictions, noise and interference can have a good immunity, diffraction and penetrating shelter is the core of COFDM technology.
