Sprintlink 2W 1.4Ghz 80km Long Range Wireless Video-Data-RC Link w/ SprintTracker

Sprintlink 2W is built especially for the scenario where the communication range is above 50km. With a 16dpi antenna panel and Sprinttracker on the ground, its communication range is over 80km, even much more. Also with re-transmission and adaptive frequency hopping, the module secures the transmission quality steadily.

Sprintlink 2w adopts private COFDM protocol, features long range transmission, high sensitivity and high throughput.

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

Features:

• TDD bi-directional link with video/telemetry/RC
• Receiving diversity and dynamic antenna switching
• H.264 & H.265 video compression & decompression
• Low level re-transmission and adaptive frequency hopping
• AES128 & AES 256 encryption implemented on FPGA

Software Defined Radio (SDR)

The realization of modifiability of the communication underlying protocol gives the system the ability to continuously evolve and optimize;

Fully and effectively verify the improvement of chipization, and greatly reduce the risk of tape-out;

Flexible customization to improve design-win capabilities

Orthogonal Frequency Division Multiplexing (OFDM)

Effectively eliminate multipath interference under long-distance transmission

Low Density Check Code (LDPC)

The self-optimized design of QC-LDPC gives the system excellent error correction performance and greatly improves the receiving performance.

Private Communication Protocol

Optimized design for video transmission, optimized frame format and pilot frequency greatly improve the receiving performance of video transmission.
