Key Features

1. High-Speed 100 Mbps Bidirectional Transmission

The radio provides up to 100 megabits per second (Mbps) of full-duplex wireless bandwidth, supporting real-time video, telemetry, and IP data. Both uplink and downlink channels operate simultaneously, enabling live HD video streaming from multiple racing vehicles while control commands and telemetry data are transmitted back without delay.

2. Optimized for Car Racing and Broadcast Environments

Designed for high-mobility and low-latency operation, the transceiver maintains continuous connectivity with vehicles moving at high speed. It supports rapid link recovery, automatic frequency adaptation, and strong error-correction performance—essential for maintaining smooth live video during fast-changing race conditions.

3. Star Networking with Up to 64 Nodes

This model supports star-topology networking, allowing up to 64 transmitting nodes (cars, cameras, or mobile units) to link to a single ground receiver. Each node can send HD video and data streams simultaneously. The central receiver intelligently manages bandwidth allocation and ensures that each feed remains synchronized and stable.

4. 22 km Line-of-Sight Coverage

With a 22-kilometer air-to-ground communication range, this radio is ideal for large race circuits, off-road events, and open-area broadcasting. The dual-antenna design and 5 W × 2 PA output guarantee robust signal penetration and consistent link quality over long distances.

5. Dual 5 W Power Amplifiers (2×5 W PA)

Each unit integrates two high-efficiency 5 W power amplifiers, delivering a total of 10 watts RF output. The extra power ensures strong signal transmission, enhanced stability in challenging environments, and superior resistance to multipath fading or interference. (2x10WPA or 2x20WPA is optional).

6. Adaptive Modulation and Coding

To optimize performance in dynamic RF conditions, the radio automatically switches between QPSK, 16QAM, and 64QAM modulation modes. This enables continuous operation with the highest possible throughput and minimal packet loss, even when the signal environment deteriorates due to interference or movement.

7. Multi-Interface Design

The transceiver includes multiple hardware interfaces to meet different integration requirements:

• 2 × RJ45 Ethernet Ports – Transparent IP transmission for video, data, or control.

• 2 × UART Serial Ports (TTL, optional RS232) – For telemetry or command signals.

• 1 × SBUS Interface – Compatible with remote-control systems.

• Power Input: 24–32 V DC via XT30PW-M connector.
  This flexible interface design makes it suitable for vehicle-mounted, airborne, or ground-based applications.

8. Dual-Antenna MIMO Technology

The 2T2R MIMO (two-transmit, two-receive) architecture enhances throughput, link stability, and spectral efficiency. The main and auxiliary antennas, connected via SMA ports, allow spatial diversity and better resistance to multipath effects common in race environments with reflective surfaces.

9. Advanced Security and Encryption

To protect valuable live footage and confidential telemetry, the system employs AES-128, SNOW 3G, and ZUC encryption algorithms. These ensure that all transmitted video and data are securely protected against unauthorized access or signal interception.

10. Web UI Configuration and Status Monitoring

Through an Ethernet connection, users can access a built-in Web UI for easy setup and real-time system monitoring. Parameters such as frequency, bandwidth, power level, and node status can be viewed and adjusted instantly. This interface also provides firmware upgrade options and network diagnostics.

11. Compact and Lightweight

The device measures only 113.9 × 83.7 × 24.5 mm and weighs 255 grams, allowing easy integration inside race cars, broadcasting vehicles, or camera rigs. Despite its small size, it delivers enterprise-grade communication performance.

12. Energy Efficient and Reliable

Operating at 24–30 V DC with typical power consumption under 23 W per node, the system offers long-term stability and minimal heat generation. The efficient design ensures reliable operation under continuous load, even in high-temperature environments.

Performance in Real Racing Environments

During a typical racing event, each car is equipped with an onboard camera system connected to the Vcan1806 radio link transceiver. The device transmits real-time HD video, driver audio, and telemetry data directly to a ground receiver located at the control tower or broadcast truck.

Even when cars move at high speed and enter temporary shadow zones, the dual-antenna MIMO design ensures quick link recovery and minimal frame loss. The star-network structure allows every car’s data to be sent to the same central receiver, simplifying synchronization and post-production workflow.

The result is a smooth, low-latency, high-definition broadcast feed, perfectly synchronized with timing and scoring systems—ensuring audiences enjoy seamless live coverage from multiple camera angles.

How to choose the Radio link Default configuration

Our radio link can be configured in two different ways depending on the customer’s priority: high data rate or strong anti-interference.

• Single band configuration (566–678 MHz or 1420–1530 MHz):
  In this mode, the radio uses only one band. It can achieve the maximum throughput of 100 Mbps (50+50 Mbps up/down). This option is best if the main requirement is high speed.

• Dual band configuration (566–678 MHz and 1420–1530 MHz):
  In this mode, the radio supports cross-band frequency hopping. If one band suffers interference, the system automatically switches to the other band. This provides stronger anti-jamming performance, but the maximum data rate is limited to 50 Mbps.

In short:

• Choose single band → up to 100 Mbps, best for high data rate.

• Choose dual band → up to 50 Mbps, best for reliability and interference resistance.
