Vim li cas thiaj ua qhov kev ncua deb wireless video transmitters pom zoo cofdm kom zoo dua

COFDM, Coded Orthogonal Frequency Division Multiplexing
1. Requires much narrower bandwidth than analog’s
2. Resistant to multi-path
3. Robust signal in NLOS (uas tsis yog-txoj kab ntawm pom)–Performing inside buildings, through walls, and around corners
4. Error correction & strong encryption
5. High performances on aircraft, vehicles, nkoj
6. Performs well in high-speed moving transmission
