Overview

Internet Connection Types

Internet connection types are broadly classified into fiber optic, ADSL, cable television lines, and mobile lines. Each has distinct characteristics in terms of communication speed, stability, installation method, and pricing structure, requiring users to choose the optimal line according to their usage purpose and living environment. In recent years, fiber optic lines have become mainstream while ADSL services are being phased out. Additionally, with the spread of 5G-compatible mobile lines, alternatives to fixed lines are expanding.
