Overview
The COFDM Wireless Video Transmitter is a high-performance, long-range digital transmission system designed for real-time HD video, audio, and data in complex environments.
Using advanced COFDM modulation, the system maintains stable, low-latency video transmission even under NLOS (Non-Line-of-Sight) conditions, high-speed movement, multipath interference, and urban environments.
Its compact design, low delay, and robust anti-interference capability make it ideal for professional applications such as UAVs, robotics, law enforcement, broadcasting, mining, and emergency command systems.
Features
- COFDM Modulation Technology – Strong anti-interference and stable signal in NLOS environments.
- Low Latency Transmission – Supports near real-time HD video (< 30–80 ms depending on model).
- Long Transmission Range – Up to several kilometers air-to-ground / ground-to-ground.
- HD Video Input – HDMI / SDI / AV optional.
- Full-Duplex Data Channel – Supports telemetry, control signals, or serial data through UART/RS232/RS485.
- High Mobility Performance – Works reliably at high speed (UAV, vehicles, robotics).
- Diverse Frequency Options – 300MHz / 800MHz / 1.2GHz / 1.4GHz / 2.4GHz / 5.8GHz etc.
- AES Video Encryption – Ensures secure transmission for government and industrial use.
- Compact, Lightweight Design – Suitable for drones and portable applications.
- Multiple Bandwidth & Power Options – 2/4/6/8 MHz bandwidth; 100mW to 5W transmitter power.
