COFDM Wireless Video Transmitter Transmission

COFDM無線視訊發射機 / Transmission System

Overview

The COFDM無線視訊發射機 是一個高性能的, long-range digital transmission system designed for 即時高清視訊, 聲音的, 和數據 in complex environments.
Using advanced 正交頻分複用調變, the system maintains stable, low-latency video transmission even under NLOS (非視距) 狀況, high-speed movement, 多路徑幹擾, and urban environments.

Its compact design, 低延遲, and robust anti-interference capability make it ideal for professional applications such as 無人機, 機器人技術, 執法, 廣播, 礦業, and emergency command systems.
