Wireless data links are the backbone of UAV video, Telemetrie, and control systems. They determine range, Zuverlässigkeit, Durchsatz, and interoperability with various platforms such as drones, Bodenroboter, or wearable devices. Wireless links can be classified according to Netzwerktopologie, power amplification, Anwendungsszenario, und Datenschnittstelle.

1. By Network Topology (Netzwerkmodus)

• Punkt-zu-Punkt (P2P)

  • Direct link between two nodes.

  • Vorteil: Einfach, Geringe Latenz, hohe Zuverlässigkeit.

  • Allgemeiner Gebrauch: UAV zur Bodenstation, remote-controlled vehicles.

• Punkt-zu-Multipunkt (P2MP)

  • One transmitter communicates with multiple receivers.

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

  • Allgemeiner Gebrauch: Swarm UAV management, multi-vehicle telemetry.

• Relaisübertragung

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

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

• IP Mesh (Selbstorganisierend, Knotenzentriertes Netzwerk)

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

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

  • Allgemeiner Gebrauch: Multi-UAV collaborative missions, robotic swarms, disaster recovery scenarios.

2. By Transmission Power (PA-Integration / Output Wattage)

• 0.5 W Wireless Link

  • Short-range, Anwendungen mit geringem Stromverbrauch.

  • Vorteil: 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

  • Große Reichweite, 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, Verteidigung, or emergency response scenarios.

3. Nach Anwendungsszenario

• UAV Wireless Data Transmission

  • Real-time telemetry, Flugkontrolle, Sensordaten, or video streaming from drones to ground stations.

  • Requirements: Geringe Latenz, Anti-Interferenz, hohe Zuverlässigkeit.

• Ground Robotic Data Transmission (beim UGV, Robotic Dogs, Mobile Platforms)

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

  • Requirements: Hohe Zuverlässigkeit, lange ausdauer, 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.

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

• S.Bus

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

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

---

5. Optional Customization / Advanced Features

• 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, S.Bus) to integrate depending on UAV or robot system.
