Wireless data links are the backbone of UAV video, telemetri, and control systems. They determine range, keandalan, keluaran, and interoperability with various platforms such as drones, robot darat, or wearable devices. Wireless links can be classified according to topologi jaringan, power amplification, skenario aplikasi, dan antarmuka data.

1. By Network Topology (Modus Jaringan)

• Titik-ke-Titik (P2P)

  • Direct link between two nodes.

  • Keuntungan: Sederhana, latensi rendah, keandalan yang tinggi.

  • Common Use: UAV ke stasiun bumi, remote-controlled vehicles.

• Titik-ke-Multipoint (P2MP)

  • One transmitter communicates with multiple receivers.

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

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

• Transmisi Relai

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

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

• IP Mesh (Pengorganisasian Mandiri, Jaringan Berpusat pada Node)

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

  • Keuntungan: 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 (Integrasi PA / Output Wattage)

• 0.5 W Wireless Link

  • Short-range, low-power applications.

  • Keuntungan: 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

  • Jarak jauh, 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, pertahanan, atau skenario tanggap darurat.

3. By Application Scenario

• UAV Wireless Data Transmission

  • Real-time telemetry, kontrol penerbangan, data sensor, or video streaming from drones to ground stations.

  • Persyaratan: Latensi rendah, anti-interferensi, keandalan yang tinggi.

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

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

  • Persyaratan: 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.

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

• S.Bus

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

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

5. Optional Customization / Fitur Lanjutan

• Adjustable Transmission Power

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

• Redundant or Multi-Path Networking

  • Untuk misi penting, 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.
