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, robotique, surveillance à distance, et d'autres applications exigeantes. Below is a detailed description of its specifications and features.
Frequency Band and Range
- Supported Frequency Bands: 800 MHz et 1.4 GHz.
- Gamme de fréquences:
- 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
- Type de modulation: OFDM (Orthogonal Frequency Division Multiplexing)
Adjustable bandwidth provides flexibility to balance between data rate and interference resistance. Narrower bandwidth is suitable for long-range, environnements sujets aux interférences, while wider channels deliver higher throughput in clean spectrum conditions.
Transmission Power and Sensitivity
- PIRE: 33 dBm ± 1 dB
- Sensibilité du récepteur: ≤ -95 dBm
The system provides strong transmission power with excellent sensitivity, enabling long-distance stable links.
Range and Data Rate
- Maximum Range: Jusqu'à 80 km (ligne de mire, with appropriate antenna setup)
- Maximum Bitrate: 30 MBPS @ 20 MHz de bande passante
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
- Consommation d'énergie: ≤ 10 W
- Connecteur d'alimentation: XT60
The wide input voltage range ensures compatibility with different UAV and vehicle power systems, while the low consumption extends operational time.
Interfaces
- Connecteurs d'antenne: Dual SMA ports for diversity and stable reception.
- UART (TTL 3.3V):
- Supports UART1 and UART2
- 1 bit de départ, 8 Bits de données, 1 bit d'arrêt, pas de parité
- Taux de bauds par défaut: 115200 points de base (other options: 57600, 38400, 19200, 9600)
- SBUS:
- SBUS_IN and SBUS_OUT for control signal transmission.
- Ports Ethernet: RJ45, 4-épingle, 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
- Bouton: 1 multi-function control button.
- Mode Switch: Dedicated switch for unité d'air et unité au sol configuration.
This simplifies setup, allowing quick adaptation between airborne and ground applications.
Antennas and RF Characteristics
- Air Unit Antenna: Antenne en bâton de colle, 20 cm, 2.5 gain de DBI.
- Ground Station Antenna: High-gain directional antenna, 120 cm, 12 gain de DBI.
- Polarisation: Verticale
- SWR (Rapport d'onde stationnaire): ≤ 2.0
The high-gain ground antenna enhances long-range performance, while the compact air antenna reduces drag and weight for UAV integration.
Performance environnementale
- Température de fonctionnement: -40°C à +70°C
- Température de stockage: -40°C à +85°C
- Humidité: 5–95%, sans condensation
With its industrial-grade design, the system is reliable in harsh environments, making it suitable for outdoor field missions, extreme climates, and professional applications.
Conception mécanique
- Dimensions: 112 × 63.5 × 21 mm
- Poids: 170 g
Its lightweight and compact size ensure easy installation on UAVs and mobile platforms without adding excessive load.
