Analysis

With satellite internet, this journey is much longer compared to other types of connections. Here’s why: The biggest reason for high latency in satellite internet is the distance data must travel. Satellites used for internet services are often in geostationary orbit, about 35,000 kilometres above Earth. For data to reach the satellite and return, it covers an enormous distance. This journey results in a delay of around 500-600 milliseconds, even in perfect conditions. By comparison, fibre optic internet has a latency of about 20 milliseconds or less. The speed of light, while incredibly fast, still creates a bottleneck for satellite communication. Even though signals travel at light speed, the sheer distance involved means a noticeable delay. This is not something that can be fixed by improving technology on the ground—it’s a limitation set by physics.
Key Points
- Why satellite internet has high latency lies in long distances, speed of light limitations, and weather dependencies causing unavoidable delays.
- Managing latency effectively involves using latency-tolerant apps, optimising your network, and exploring low Earth orbit (LEO) satellite services.
Actions
Pending intelligence enrichment.
