Satellite internet
위성 인터넷
Internet that connects through satellites in the sky instead of base stations on the ground.
Overview
Older satellite internet used a few satellites at a very high altitude, so it was slow and signals arrived late. Today thousands of satellites are placed in low orbit, and your connection switches between whichever ones pass close by. That makes it much faster and more responsive.
The common setup is a small dish antenna at home, and services that connect phones directly to satellites are starting too. SpaceX's Starlink is the best-known example.
An everyday example
Even in the mountains or in the middle of the ocean, where no cable reaches, you can get internet as long as you can see the sky.
Why it matters
It connects places on Earth that the internet never reached, and it stands in when disasters or war cut the communication network. Countries are also racing to have their own satellite networks.
