MESH Bidirectional Network Transmission System

The MESH bidirectional network transmission system is an advanced wireless communication solution designed for long-distance, high-speed, and reliable data transmission in both line-of-sight (THE) and non-line-of-sight (NLOS) environments. This self-organizing network system leverages TDD-COFDM (Time Division Duplex – Coded Orthogonal Frequency Division Multiplexing) transfer protocol, providing superior performance in complex and challenging environments. Its design emphasizes robustness, flexibility, and scalability, making it suitable for professional UAV, UGV, USV operations, industrial monitoring, and security applications.

Main Features

1. TDD-COFDM Transfer Protocol – The system adopts a TDD-COFDM protocol, which allows simultaneous bidirectional communication with strong resilience to multipath interference, fading, and signal obstruction. This enables stable video and data transmission even in urban or heavily forested areas.
2. Long-Distance Video Transmission – Designed to transmit images and video over long distances, the system supports distances of up to 1.5 km nlick (non-light-of-sight) and up to 30 km. This ensures real-time monitoring for applications such as drones, industrial facilities, security, and emergency response operations.
3. Mesh Networking Capability – The system supports peer-to-peer and point-to-multipoint communication, forming a dynamic, self-organizing MESH network. Each device functions as a node that can relay signals to extend coverage and maintain connectivity in areas where direct communication is impossible.
4. Flexible Network Architecture – The MESH system allows automatic networking with minimal configuration. Nodes can be added or removed without affecting the overall performance, providing highly adaptable network coverage suitable for mobile platforms such as drones, vehicles, and portable monitoring stations.
5. Web-Based Device Management – A web device management UI allows operators to view, modify, and configure wireless video and data links for UAV IP cameras and other networked devices. Parameters such as frequency, bandwidth, and encryption can be adjusted remotely, providing high operational flexibility.
6. Integrated Video and Data Transmission – The system can transmit HD video, audio, and telemetry data over a single wireless link. It supports HDMI, SDI, and IP camera inputs, with downlink video delivered in real-time to the receiver while simultaneously transmitting uplink control commands, telemetry, or sensor data.
7. Dual RS232 Ports – Each module features two bidirectional RS232 serial ports, allowing seamless integration with existing control systems, PTZ cameras, telemetry equipment, and other serial-based devices.
8. Durable and Weatherproof Design – The system uses waterproof aviation connectors, IP67-rated housing, and wide-temperature components, ensuring continuous operation in harsh environments ranging from -40°C to +85°C. This makes it suitable for outdoor deployments, industrial monitoring, or mobile operations on UAVs, UGVS, and USVs.
9. Lightweight and Compact – Each node measures approximately 180 x 180 x 50 mm and weighs around 2 kg, making it lightweight and easy to integrate into vehicles, drones, or hand-held systems. Despite its compact form factor, it delivers high-performance transmission comparable to larger traditional solutions.
10. High-Speed Automotive Compatibility – Specially optimized for high-speed vehicles, the system maintains stable reception and video quality even when traveling above 160 km/h, ideal for on-road or in-vehicle monitoring.
11. Flexible Frequency and Output Power – The system operates at 2.4 GHz, with an output power of up to 27 dBm, providing strong signal coverage and reliable connectivity across multiple nodes. Bandwidth and modulation schemes, including QPSK with FEC coding, are configurable to match environmental conditions and application requirements.
12. Low Latency – The system maintains ultra-low latency transmission, ensuring real-time video and data flow for UAV control, security monitoring, or live-streaming applications. Latency is optimized even when multiple nodes relay signals within the mesh network.
13. Energy-Efficient Design – Despite its high performance, the maximum power consumption of the receiver is only about 3W, making it suitable for battery-operated mobile deployments or long-term field monitoring.
14. Versatile Applications – The MESH bidirectional network transmission system is suitable for a wide range of industries and scenarios:

• Drone/UAV Operations: Real-time video, telemetry, and control transmission.
• Unmanned Ground and Surface Vehicles (UGV/USV): Reliable long-range communication for exploration, monitoring, or surveillance.
• Industrial and Security Monitoring: Transmission of images from remote or hazardous locations such as factories, warehouses, and forested areas.
• Public Safety and Emergency Response: Enables mobile teams to transmit high-definition video and telemetry data during disaster management or firefighting.
• Internet of Things (IoT) and Smart Infrastructure: Self-organizing network for sensor data and IP camera integration in agriculture, water management, and energy sectors.

15. Demo Videos and Proven Performance – The system has been tested in various scenarios:

• 1.5 km NLOS demonstration indoors and on roads using COFDM-912T.
• UAV to ground video transmission over 65 km using Vcan1702 modules.
• Live HDMI streaming from handheld or vehicle-mounted transmitters.

16. Customizable Standards – The hardware and software of the MESH system can be customized for different applications, including modulation, frequency range, connector type, and data interface, ensuring flexibility for unique project requirements.

In conclusion, the MESH bidirectional network transmission system provides a robust, flexible, and reliable solution for long-distance video and data transmission. Its self-organizing mesh network architecture, bidirectional data ports, IP67 protection, low latency, and wide operating temperature range make it suitable for UAVs, UGVS, USVs, industrial monitoring, security, and other professional applications where high-quality video transmission and network reliability are critical. The system’s combination of COFDM technology, waterproof aviation connectors, and flexible web-based configuration ensures that it can adapt to complex deployment scenarios while maintaining stable, high-quality video and telemetry links.
