100KM ultra long distance wireless transmission, excellent non line of sight anti-interference performance.

The ultra-high bandwidth and stream support can easily handle 4K resolution video data streams. The 200ms screen to screen low latency and delay jitter sensitivity control is good, meeting the real-time requirements of video data end-to-end

H265/H264 video compression. Criptografia AES.

The implementation of an adaptive retransmission mechanism at the bottom layer not only greatly outperforms the retransmission mechanism at the application layer in terms of efficiency and latency, but also greatly improves the performance and user experience of the link in interference environments.

The module continuously detects the interference status of all available channels in real-time, and automatically selects and switches to the channel with the lowest interference in the current working channel, ensuring continuous and reliable communication.

The point-to-point system has a flexible and adjustable time slot allocation mechanism, and the time slot positions of each terminal are flexible and adjustable. According to the terminal data flow, the number of time slots allocated to each terminal can be equal or unequal, thus achieving the optimal overall system efficiency.
