frequency hopping

2.4GHz&5.8GHz dual frequency image transmission

Compact layout 65 × 43mm, weighing only 14g, can be integrated into remote control, ground station, or added to form a module with an outer shell

The Sprintlink DUO can automatically switch to the 5.8GHz frequency band, providing strong support for reliability through automatic switching, retransmission, and fast connection.

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.

Mô-đun liên tục phát hiện trạng thái nhiễu của tất cả các kênh khả dụng trong thời gian thực, and automatically selects and switches to the channel with the lowest interference in the current working channel, ensuring continuous and reliable communication.
