Comparison: 5G vs. Starlink for Maritime Connectivity

The maritime industry increasingly depends on advanced connectivity solutions to support operations, improve security, and enhance crew welfare. Both 5G and Starlink present significant opportunities, but they differ in their technical implementation, range, and applications.

Coverage

• 5G: Primarily reliant on terrestrial infrastructure, with signal propagation limited by distance and geography. Coastal areas and nearby offshore operations benefit from hybrid 5G networks using satellites and terrestrial stations, such as in South Africa’s Mossel Bay project (22 km offshore range). Inmarsat's trials using mm Wave frequencies for mesh networking aim to push this range but remain constrained compared to satellite coverage.
• Starlink: Utilizes a global network of low-Earth orbit (LEO) satellites, providing virtually universal coverage, including remote and deep-sea regions. Offers connectivity far beyond 5G's reach, making it ideal for mid-ocean voyages and deep-sea research.

Latency and Speed

• 5G: Offers low latency (1 ms to 10 ms) in optimal conditions, critical for applications like real-time data analysis, IoT device synchronization, and augmented reality. Provides ultra-high-speed internet suitable for bandwidth-intensive tasks such as remote diagnostics and video streaming.
• Starlink: Provides low latency (20 ms to 40 ms) for a satellite-based service, but higher compared to 5G due to the distance signals must travel between satellites and Earth. Speeds of up to 250 Mbps are achievable, sufficient for high-definition video calls, navigation, and IoT applications.

Infrastructure Requirements

• 5G: Requires significant infrastructure, including terrestrial towers, underwater cables, and integration with satellite networks for offshore applications. Deployment is cost-intensive but yields exceptional speed and latency in densely populated or industrialized areas.
