FAQ

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

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

• Pag-uplink (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 sa 6000 MHz
• RX (downlink): User configurable from 170 MHz sa 860 MHz
• For RX frequencies over 860 MHz, isang karagdagang 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?

A: This system combines the best features of FD (Frequency Division Duplex) at TD (Dibisyon ng Oras Duplex) 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, awtomatikong pagpili ng dalas, adaptive bitrate, Awtomatikong pag -retra, 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: Sinusuportahan ng hanggang 200 km air-to-ground range and up to 16 Mbps bandwidth, allowing you to transmit clear HD video while simultaneously sending telemetry and control data in both directions.

Sa simpleng mga termino: 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. Ang FD + TDD hybrid gives you the perfect balance: mababang latency + mataas na kahusayan + malakas na pagganap ng anti-interference, making it ideal for demanding drone applications such as power line inspection, pagtugon sa emergency, aerial surveying, and long-range surveillance.
