Why do long-distance wireless video transmitters recommend cofdm advantage?

COFDM, Coded Orthogonal Frequency Division Multiplexing 1. Requires much narrower bandwidth than analog's 2. Resistant to multi-path 3. Robust signal in NLOS (non-line of sight)--Performing inside buildings, through walls, and around corners 4. Error correction & strong encryption 5. High performances on aircraft, vehicles, ships 6. Performs well in high-speed moving transmission
