Wireless Video Transmission System Specifications
This wireless video transmission system is designed for long-range, high-stability communication between airborne platforms and ground stations. Built with advanced OFDM modulation and optimized RF performance, it provides reliable connectivity for UAVs, robotics, remote monitoring, and other demanding applications. Below is a detailed description of its specifications and features.
Frequency Band and Range
- Supported Frequency Bands: 800 MHz and 1.4 GHz.
- Frequency Range:
- 800 MHz: 806 MHz – 825 MHz
- 1.4 GHz: 1427 MHz – 1447 MHz
This dual-band capability allows flexible deployment in different regions and applications, ensuring adaptability to both low-frequency penetration (800 MHz for better NLOS conditions) and higher frequency for increased throughput (1.4 GHz).
Bandwidth and Modulation
- Available Bandwidth Options: 3 MHz / 5 MHz / 10 MHz / 20 MHz
- Modulation Type: OFDM (Orthogonal Frequency Division Multiplexing)
Adjustable bandwidth provides flexibility to balance between data rate and interference resistance. Narrower bandwidth is suitable for long-range, interference-prone environments, while wider channels deliver higher throughput in clean spectrum conditions.
Transmission Power and Sensitivity
- EIRP: 33 dBm ± 1 dB
- Receiver Sensitivity: ≤ -95 dBm
The system provides strong transmission power with excellent sensitivity, enabling long-distance stable links.
Range and Data Rate
- Maximum Range: Up to 80 km (line-of-sight, with appropriate antenna setup)
- Maximum Bitrate: 30 Mbps @ 20 MHz bandwidth
This makes the system suitable for real-time HD video transmission and telemetry even over extreme distances.
Power Supply and Consumption
- Power Input Range: DC 9 V – 28 V
- Power Consumption: ≤ 10 W
- Power Connector: XT60
The wide input voltage range ensures compatibility with different UAV and vehicle power systems, while the low consumption extends operational time.
Interfaces
- Antenna Connectors: Dual SMA ports for diversity and stable reception.
- UART (TTL 3.3V):
- Supports UART1 and UART2
- 1 start bit, 8 data bits, 1 stop bit, no parity
- Default baud rate: 115200 bps (other options: 57600, 38400, 19200, 9600)
- SBUS:
- SBUS_IN and SBUS_OUT for control signal transmission.
- Ethernet Ports: RJ45, 4-pin, and 7-pin (with +12V output for powering external devices).
These versatile interfaces support multiple integration options, from telemetry and control data to Ethernet-based video streaming.
Controls and Switching
- Button: 1 multi-function control button.
- Mode Switch: Dedicated switch for air unit and ground unit configuration.
This simplifies setup, allowing quick adaptation between airborne and ground applications.
Antennas and RF Characteristics
- Air Unit Antenna: Glue-stick antenna, 20 cm, 2.5 dBi gain.
- Ground Station Antenna: High-gain directional antenna, 120 cm, 12 dBi gain.
- Polarization: Vertical
- SWR (Standing Wave Ratio): ≤ 2.0
The high-gain ground antenna enhances long-range performance, while the compact air antenna reduces drag and weight for UAV integration.
Environmental Performance
- Operating Temperature: -40°C to +70°C
- Storage Temperature: -40°C to +85°C
- Humidity: 5–95%, non-condensing
With its industrial-grade design, the system is reliable in harsh environments, making it suitable for outdoor field missions, extreme climates, and professional applications.
Mechanical Design
- Dimensions: 112 × 63.5 × 21 mm
- Weight: 170 g
Its lightweight and compact size ensure easy installation on UAVs and mobile platforms without adding excessive load.
Summary
This wireless video transmission system combines long-range capability (up to 80 km), high throughput (30 Mbps), and robust OFDM modulation with flexible interface options (UART, SBUS, Ethernet). With support for both 800 MHz and 1.4 GHz bands, it provides excellent adaptability for different regions and mission types.
