15KM 30KM 50KM Ultra Long Distanceimage Link HD Signal Transmission
Designed for scenarios demanding far-reaching visual connectivity, this image link system delivers ultra-long-distance HD signal transmission with three flexible range options: 15KM, 30KM, and 50KM (LOS). It ensures stable, high-definition video and data transfer, maintaining clear signal integrity even in open outdoor environments like aerial surveys, remote inspections, or large-scale industrial monitoring.
Engineered with anti-interference technology, it resists electromagnetic disruptions to keep transmission latency low—critical for real-time operations such as UAV piloting or long-range surveillance. Its versatile range adaptability makes it suitable for both mid-distance tasks (e.g., urban perimeter monitoring) and long-haul missions (e.g., rural infrastructure inspections), meeting diverse professional needs for reliable, long-range visual communication.
Three-in-One Integration: Image, Data & Control: Features a one-way image transmission channel, a two-way digital transmission channel, and a one-way remote control channel, realizing integrated management of visual, data, and control signals.
50KM Ultra-Long-Distance Wireless Transmission: Delivers exceptional connection efficiency for extended-range transmission (for further distance needs, please refer to the high-power 2W module). Ground-to-air field tests have achieved beyond-line-of-sight (BLOS) interconnection up to 20KM; end-to-end devices are free from wired constraints, ensuring high spatial and distance freedom plus mobility.
4K HD Images & Low Latency: Ultra-high bandwidth and bitstream support easily handle 4K resolution video streams. With a screen-to-screen latency as low as 200ms and minimal delay jitter, it enables more responsive control, meeting end-to-end real-time requirements for video data.
Advanced Video Compression & Encryption: Supports H265/H264 video compression standards to optimize bandwidth usage, paired with AES encryption to safeguard data security during transmission.
Flexible Interface Options: Offers three optional interface combinations: HDMI+Ethernet (output via HDMI), HDMI+AV (output via HDMI), and SDI+AV (output via HDMI), adapting to diverse device connection needs.
Efficient Adaptive Retransmission Mechanism: The underlying adaptive retransmission mechanism outperforms application-layer retransmission in both efficiency and latency. It significantly enhances link performance and user experience in interference-prone environments.
Real-Time Channel Interference Detection & Auto-Switching: The module continuously monitors the interference status of all available channels in real time. When the current working channel is interfered with, it automatically selects and switches to the channel with the lowest interference, ensuring uninterrupted and reliable communication.
TechnIcal Advantages
Software Defined Radio (SDR)
Modifying the underlying communication protocol equips the system with the capability for continuous evolution and optimization, allowing it to adapt to evolving application needs and performance requirements over time.
It enables comprehensive and effective verification of chip-based enhancements, significantly mitigating the risks associated with chip tapeout—such as functional errors or performance gaps that could arise during mass production.
With support for flexible customization, the SDR solution enhances the ability to secure design wins, as it can be tailored to meet the unique technical specifications and use-case demands of different customers or industries.
Orthogonal Frequency Division Multiplexing (OFDM)
Orthogonal Frequency Division Multiplexing (OFDM) effectively mitigates multipath interference, ensuring reliable signal transmission even over long distances.
Low Density Check Code (LDPC)
The self-optimized design of QC-LDPC endows the system with exceptional error correction capabilities, significantly enhancing its receiving performance.
Private Communication Protocol
This private communication protocol features an optimized design tailored for video transmission. Its refined frame format and enhanced pilot frequency work in tandem to significantly boost the receiving performance of video transmission, ensuring stable and high-quality visual data delivery.
