Solution for HDMI video telemetry and RC transmitter for 15km range

Solution for HDMI Video, Telemetry, and RC Transmitter for 15Km Range

We understand your requirement for a professional-grade HDMI video, telemetry, and RC transmitter system capable of operating over long distances, specifically around 15 kilometers. Such a system is critical for UAV, drone, and other remote operations where high-quality video transmission, reliable telemetry data, and robust remote control signals are required simultaneously. Below, we provide detailed information about the solution we can offer, including capabilities, limitations, and technical considerations.

1. Solutions for HDMI Video, Telemetry, and RC Transmission at 15Km

Yes, we offer a complete solution that meets your requirements for transmitting HDMI video, telemetry, and RC control signals over a 15-kilometer distance. Our system is specifically designed for UAV and drone applications where high-definition video, real-time control, and telemetry feedback are essential for mission success.

The solution integrates a high-performance wireless video transmitter capable of encoding HDMI video into a robust COFDM or OFDM transmission format. This ensures that even in challenging environments with potential interference, multipath effects, and obstacles, the video signal remains stable and high quality. The transmitter simultaneously supports telemetry data and RC control channels, combining all essential communication links in a single system. This integration reduces the need for multiple separate transmitters, simplifies installation, and minimizes payload weight on UAV platforms.

The system supports high-definition HDMI input, enabling direct connection to cameras, UAV gimbals, or other video sources. The transmitted video maintains Full HD quality, with low latency to ensure real-time situational awareness and precise control for UAV operators. The telemetry link allows for real-time status monitoring of UAV parameters such as GPS coordinates, battery level, altitude, and other sensor data. RC signals are transmitted reliably alongside video and telemetry, maintaining control of the UAV across the full operational range.

2. Non-Line-of-Sight (NLOS) Operation Using Relays

Regarding the NLOS situation, our solution supports one relay in mesh mode, allowing a secondary UAV or relay station to extend the effective communication range and bypass obstacles such as buildings, hills, or trees. In this mode, the primary UAV transmits video, telemetry, and control signals to a relay UAV, which then forwards the signals to the ground control station (GCS).

It is important to note that while one relay is supported, using two or more relays in series may significantly reduce the available data rate due to cumulative signal processing and retransmission delays. Therefore, for long-range operations involving NLOS conditions, we recommend planning the deployment with one relay UAV positioned strategically to maintain line-of-sight to both the primary UAV and the GCS. This configuration ensures a robust and stable connection without significantly compromising video quality or telemetry data rate.

3. Data Rate Performance

Our system is capable of maintaining a data rate greater than 1.2 Mbps at a distance of 15 kilometers, which meets most high-definition video and telemetry requirements. In fact, under optimal conditions, the system can support up to 4 Mbps, providing sufficient bandwidth for Full HD HDMI video, multiple telemetry channels, and RC control data simultaneously.

This high data rate ensures that video streams remain smooth, telemetry data is transmitted in real time, and RC commands are received without delay, even at extended ranges. The system employs advanced FEC (Forward Error Correction) and robust modulation schemes such as COFDM or OFDM to maintain signal integrity, minimize packet loss, and resist interference from other RF sources operating in the same frequency band.
