LinkAV -C650H 1W HD Cofdm Wireless Aircraft Transmitters advantages: Mainly used in UAV video Aerial photography transmission scenario, the device will transmit video signal to the handheld receiver and display video images,can do real-time monitoring. LinkAV -C650H-HD mini portable HD wireless video transmission equipment is new generation of real-time broadcast-quality high-resolution image transmission system. It adopts the current leading COFDM modulation technology and relative narrow-band frequency 1.25/2.5/6/7/8MHz(optional), it has the strong anti-jamming capability, overcomes the reflection and cover caused by transmission multipath simulation technique and conventional modulation techniques, to realize high-speed photography and real-time transmit high quality image in NLOS or complicated working environment. 1. High quality digital video processing 2. COFDM modulation, H.264 coding and encoding 3. Vibration and shock resistant 4. Real-time transmission system, delay time for end-to-end is less than 500ms; 5. Great action ability, can transmit images voice stably in the condition of high speed movement and multi-path interference. 6. Support NLOS (non-line of sight) transmission, strong diffraction capability; 7. Long range transmission distance; 8. Spatial diversity reception ability, support high-speed mobile transmission. 9. Stable signals, image clear and stable, has no mosaic or drag phenomenon. 10. Extreme lightweight and rugged housing ,mini size. Applications: Our main products are COFDM, TDD and 4G wireless video transmitter & receiver, which are widely used in city security, police forces, forest fire prevention surveillance, harbor wharf video surveillance, construction sites surveillance, tunnel, oil field, UAV, automobile surveillance, Fire Services, Port Security, Homeland Security, Traffic Management, Police Technical Support Units, Special Forces, Military Command and Control Posts, Airport, Border Control, Major Incident Support etc. COFDM Video transmitter Anti-electromagnetic interference performance: It has superior performance against frequency selective fading or narrow bandwidth interference and signal waveform interference. It has strong anti-fading ability, through each subcarrier joint coding. In single carrier system(digital microwave, spread spectrum system, etc), single decline or interference will result in all communication link failure. But in multiple carrier COFDM system, only a few subcarriers will be interfered What’s more, these sub-channel can adopt ECC to correct error, to guarantee the transmission low error rate. COFDM Video transmitter Anti-multipath fading: It can confront signal waveform interference effectively; suitable for multi-path environment and fading channel high-speed data transmission. When the frequency selective fading appear in the channel because of multi-path transmission, only the sub-carrier, which fell over the band depression, and the information carried will be affected. Other sub-carriers will not be affected. Thus, the system total error rate performance will be much better.
