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, and other demanding applications. 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 (Multiplexage par répartition orthogonale de la fréquence)

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

• 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 Mbit/s @ 20 Bande passante MHz

This makes the system suitable for real-time HD video transmission and telemetry even over extreme distances.

---

Power Supply and Consumption

• Power Input Range: CC 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 3,3 V):
  • Supports UART1 and UART2
  • 1 peu de démarrage, 8 bits de données, 1 peu d'arrêt, pas de parité
  • Default baud rate: 115200 bps (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 aérienne et unité au sol configuration.

This simplifies setup, allowing quick adaptation between airborne and ground applications.

---

Antennas and RF Characteristics
