FAQ

Q: Can the uplink and downlink working frequencies be configured by the user?

UN: For standard models, the working frequencies are factory preset and cannot be modified by the user.

• Collegamento in salita (f2): 1.4 GHz
• Downlink (f1): 17 GHz

If your application requires user-adjustable frequencies, we recommend using the FDD transceiver module.

• TX (uplink): User configurable from 170 MHz a 6000 MHz
• RX (downlink): User configurable from 170 MHz a 860 MHz
• For RX frequencies over 860 MHz, un ulteriore down-conversion stage is required.

Please select the appropriate model based on whether fixed or user-configurable frequency operation is needed.

Q: What are the advantages of the FDD + TDD hybrid technology in this video & data transmission system?

UN: This system combines the best features of FDD (Divisione di frequenza duplex) e TDD (Duplex a divisione temporale) to deliver superior performance for professional drone operations.

• Real-time two-way communication with ultra-low latency (FDD advantage): Separate frequencies are used for downlink (video & data to ground) and uplink (control commands from ground). This enables true simultaneous transmission, so you get smooth live video and instant control response without any waiting or switching delays.
• High spectrum efficiency and flexible bandwidth allocation (TDD advantage): The system dynamically adjusts bandwidth between video and control/data as needed. This allows higher overall data rates and makes the best use of available radio spectrum.
• Excellent anti-interference capability and reliability: With real-time interference detection, selezione automatica della frequenza, adaptive bitrate, ritrasmissione automatica, and smart power control, the link remains stable even in complex environments with multipath interference or crowded radio frequencies.
• Long range and high-quality transmission: Supporta fino a 200 km air-to-ground range and up to 16 Mbps la larghezza di banda, allowing you to transmit clear HD video while simultaneously sending telemetry and control data in both directions.

In termini semplici: Pure FDD offers excellent low-latency two-way performance but can be less spectrum-efficient. Pure TDD is very efficient and flexible but may introduce slight delays. Il FDD + TDD hybrid gives you the perfect balance: bassa latenza + high efficiency + forti prestazioni anti-interferenza, making it ideal for demanding drone applications such as power line inspection, risposta all'emergenza, rilevamento aereo, and long-range surveillance.
