7KM Wireless Video Data RC Transmission System – Long-Range Integrated OFDM Solution
Overview
The 7KM Wireless Video Data RC Transmission System is a next-generation long-range wireless communication platform that combines video transmission, data link, and RC control into a single highly integrated solution. Designed for UAVs, robotics, unmanned ground vehicles, public safety systems, industrial monitoring, and military-grade reconnaissance, this system offers both a 7km version and an extended 15km version, providing operators with flexibility depending on mission requirements.
Leveraging advanced OFDM modulation, adaptive bandwidth selection, and multiple frequency band options (800MHz, 1.4GHz, and 2.4GHz), the system ensures robust connectivity with minimal latency. It supports HDMI/SDI/CVBS video inputs on the transmitter, and HDMI/Ethernet outputs on the receiver, enabling seamless integration with cameras, displays, and IP-based systems. With ultra-low latency video encoding (H.264/H.265) and reliable bi-directional data/RC transmission, the platform delivers a complete communication backbone for modern unmanned systems.
Key Advantages
-
Three-in-One Integration
Unlike traditional setups that require separate video, data, and RC transmission modules, this system consolidates all three into a compact lightweight unit. This reduces payload weight, simplifies wiring, and enhances reliability in demanding field applications. -
Flexible Range Options – 7km & 15km
Available in two configurations, users can select the standard 7km system for short-to-medium range operations, or the extended 15km system for long-range UAV missions, border patrol, or beyond-line-of-sight (BLOS) applications. -
Multi-Band Frequency Support
The system supports three distinct frequency ranges:-
800MHz (806~825 MHz) – optimal for penetrating obstacles and ensuring reliable links in urban environments.
-
1.4GHz (1430~1444 MHz) – balanced between penetration and data throughput, suitable for mixed terrain.
-
2.4GHz (2408~2480 MHz) – high-bandwidth performance in open-air conditions, ideal for UAVs and drones.
Operators can configure frequency and output power via software, making it adaptable to different regulatory environments.
-
-
Low Latency Performance
-
Video latency: as low as 250ms for full HD 1080p streams.
-
Data/RC latency: as low as 50ms, ensuring smooth control responsiveness even in long-range conditions.
This makes the system highly suitable for real-time FPV drone piloting, tactical surveillance, and live broadcasting.
-
-
High-Quality Video Transmission
With support for HDMI / CVBS / SDI inputs and output resolutions up to 1080p60, the system delivers broadcast-grade video quality. Adaptive encoding between H.265 and H.264 ensures efficient bandwidth utilization while maintaining clarity. Adjustable bitrates (2–12Mbps) give users control over performance depending on mission priorities. -
Robust Data Link Integration
The system includes UART, SBUS, and CAN bus compatibility, enabling it to carry telemetry, navigation, or custom control data alongside the video stream. This bi-directional data link is critical for UAV command/control, gimbal operation, sensor feedback, and real-time decision-making. -
Durability and Field-Readiness
Built for harsh environments, the system is tested to operate in temperatures from -40°C to +70°C, withstanding high humidity, vibration, and interference. Both transmitter and receiver feature rugged antenna designs optimized for air-to-ground links.
