1. By Network Topology (群組網方式)

• 點對點 (對等)

  • Direct link between two nodes.

  • 優勢: 簡單的, 低延遲, 高可靠性.

  • Common Use: 無人機至地面站, 遙控車輛.

• 點對多點 (點對多點)

  • One transmitter communicates with multiple receivers.

  • 優勢: Efficient broadcasting to several ground stations or UAVs simultaneously.

  • Common Use: Swarm UAV management, multi-vehicle telemetry.

• 中繼傳輸

  • Data is forwarded through one or more intermediate nodes to extend range or bypass obstacles.

  • 優勢: Overcomes line-of-sight limitations, suitable for long-range or urban operations.

• IP Mesh (自組織, 以節點為中心的網絡)

  • Nodes automatically route data between each other without a central server.

  • 優勢: Highly resilient to node failure, flexible for large-scale UAV or robotic networks.

  • Common Use: Multi-UAV collaborative missions, robotic swarms, disaster recovery scenarios.

2. By Transmission Power (廣播集成 / Output Wattage)

• 0.5 W Wireless Link

  • Short-range, low-power applications.

  • 優勢: Lower energy consumption, suitable for small drones or indoor use.

• 1 W Wireless Link

  • Moderate range, typical for standard UAV-to-ground links.

• 10 W Wireless Link

  • 遠距離, high-performance links for professional UAV operations.

• 20 W Wireless Link

  • Very long-range applications, can penetrate obstacles and cover several kilometers.

  • Often used in industrial, 防禦, or emergency response scenarios.

3. By Application Scenario

• UAV Wireless Data Transmission

  • Real-time telemetry, 飛行控制, 感測器數據, or video streaming from drones to ground stations.

  • 要求: 低延遲, 抗干擾, 高可靠性.

• Ground Robotic Data Transmission (在無人車, Robotic Dogs, Mobile Platforms)

  • 遙測, sensor fusion, remote control signals for autonomous or semi-autonomous robots.

  • 要求: High reliability, long endurance, adaptable to urban or rugged terrain.

---

4. By Data Interface

• TTL (Transistor-Transistor Logic)

  • Simple UART-based communication, common in microcontrollers and lightweight UAV systems.

• RS232

  • Standard serial interface for industrial or professional equipment.

  • 優勢: Reliable over longer cables and noise-prone environments.

• 總線

  • Specialized serial protocol widely used in UAV flight controllers and RC systems.

  • 優勢: Supports multiple channels on a single line for telemetry and control.

5. Optional Customization / 進階功能

• Adjustable Transmission Power

  • Some wireless links allow customers to select PA wattage depending on required range.

• Redundant or Multi-Path Networking

  • For critical missions, links may be configured with relays, mesh nodes, or multiple antennas to improve reliability.

• Modular Interfaces

  • Customers can choose which serial/data interface (TTL, RS232, 總線) to integrate depending on UAV or robot system.
