ADSL

ADSL is a technology for internet connection that utilizes the existing telephone network to transmit high-speed data through copper telephone cables. Unlike dial-up connections that use a fixed telephone line to establish internet access, ADSL provides a constant and always-on connection, allowing users to browse the internet and use online services without dialing a phone number. The main characteristic of ADSL is its asymmetry, which means it offers higher download speeds compared to upload speeds.


In daily life, ADSL was one of the first high-speed internet connection technologies widely adopted by both households and businesses. For example, a family can use an ADSL connection to browse the internet, stream videos, send emails, and download files. Offices can utilize ADSL to access cloud services, send large files, and conduct video conferences. Despite the advent of faster technologies such as fiber optics and 4G/5G, ADSL remains a popular choice in many areas where other high-speed connection options are not available.


In Switzerland, ADSL was initially used to provide high-speed internet connections to residential and commercial users. However, with technological advancements, many areas in Switzerland now have access to faster internet connections such as fiber optics and mobile hotspot connections with 4G/5G, leading to a gradual transition from ADSL to more modern technologies.
