Long range cofdm module low latency HD 1080P wireless video transmitter module

I am currently budgeting a new project I kindly ask you to provide me with more OEM modules for our drones.

—— Karpovets

We have conducted test on air indoor and in strong multipath area with many wifi interferences and also a cellular repeater inside the buiding. Fortunately your system COFDM TDD IP radio with our new amplifier run fine and better than we have expected.

—— Ducasse

I've made transmition test with the 1080p emitter you send us last year and it works perfectly. Now we have the project to send a 4k video at 500m with a ground to ground transmission, please give us some solutions.

Long range cofdm module low latency HD 1080P wireless video transmitter module



Product description


SK-530 (70mm*50mm) H.264 FHD COFDM transmitter module and SK-620(120mm*65mm)receiver module are belongs to industrial-grade miniaturization full high-definition wireless video transmission module,which support full-functional interface (SDI, HDMI, CVBS ), low latency (200ms) end to end transmission, using military-grade 128-bit dynamic non-standard AES encryption, and transparent serial data transmission can easily loading GPS data, sensor data collection, small size and low power consumption.



Using the support of non line of sight (NLOS) transmission and COFDM multi-carrier modulation technology, with low latency and high efficiency H.264 compression coding method, to improve the coding efficiency and reduce the coding delay, optimization algorithm, anti error rate and further improve the image quality,at the lowest rate to achieve the best image compression. Using advanced video pre-processing technology and efficient video coding algorithm, to provide high quality and low rate of broadcast audio and video signal transmission for high-definition digital television broadcasting system, mobile TV system, IPTV system, making it easy to manage the network expansion problems, greatly enhance the utilization of the available bandwidth, effectively save transmission costs for operators.
