Ngano nga ang mga long-distance nga wireless video transmitters nagrekomenda sa kaayohan sa cofdm

COFDM, Gi-code nga Orthogonal Frequency Division Multiplexing
1. Requires much narrower bandwidth than analog’s
2. Resistant to multi-path
3. Robust signal in NLOS (non-linya sa panan-aw)–Performing inside buildings, through walls, and around corners
4. Error correction & strong encryption
5. High performances on aircraft, vehicles, mga barko
6. Performs well in high-speed moving transmission
