Sprintlink Pro SPECIFICATIONS
Brand Name: Sprintlink
Origin: Mainland China
Recommend Age: 14+y
This is the newest version of Sprintlink Pro 1.4g 30km video-data-RC link. Sprintlink Pro is with a wireless transmission range over 30km. With the special SprintTracker, its communication range even can be up to 50km. It adopts private COFDM protocol, features long range transmission, high sensitivity and high throughput.
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.
The adaptive retransmission mechanism implemented at the bottom layer is not only much better than the retransmission mechanism of the application layer in terms of efficiency and delay, but also greatly improves the performance and user experience of the link in the interference environment.
Features:
• TDD bi-directional link with video/telemetry/RC
• Receiving diversity and dynamic antenna switching
• 30KM wireless transmission (Support longer distance to 50km)
• 4K HD images with low latency
• 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.
