2W COFDM NLOS Backpack Wireless Microwave Mobile Video Transmitter

2W COFDM NLOS Backpack Wireless hd transmitter Microwave Mobile Video cofdm Transmitter 0



The Linkav-C321 series are based on MPEG-II and H.264 encoding technology, the HD digital wireless video transmission equipment was first developed in 2011. The system uses 300-900MHz frequency, advanced COFDM, QPSK, QAM modulation technology, highly improves the transmission, disturbance and the combination of the image quality , the high transmission specifically comes to more than 5KM .

  • Low latency
  • Working frequency and RF bandwidth self-adapted within specified range
  • Separately workable and also compatible with external power amplifier
  • Low power consumption, small size and portable usage
  • IP camera compatible
  • Reliable Military Components
  • External lithium battery, easy operation and battery replacement
  • Mostly applied to Surveillance Systems for Security Departments


Product Features:


The system is suitable for HD on live of sporting events, cultural activities, important events as well as aerial photography and so on. 

H.264 encoder makes a very fruitful refinement and improvement in the efficiency of encoding, reducing coding delay, algorithm optimization, anti-error rate and further improvement of the picture quality.  Achieve the best video compression by the lowest Bit rate. Use the advanced video pre-processing technology and efficient video coding algorithm to provide high-quality, low-rate broadcast audio and video signals for digital television broadcasting system, mobile TV systems, IPTV system. Large output power (0.5W-- 2W), adjustable on site,  long distance of transmission, good diffraction ability. The video is clear and stable, can be converted to seamless HD, has no mosaic or drag phenomenon.
