Wi-Fi, short for Wireless Fidelity, is a technology that allows electronic devices to connect to the internet or communicate with each other wirelessly using radio waves. Wi-Fi is widely used to provide internet connectivity to computers, smartphones, tablets, smart TVs, and many other devices. Wi-Fi routers create a wireless local network that allows devices to access the internet and communicate with each other within a certain coverage area and are the main alternative to using mobile hotspots.

In everyday life, Wi-Fi is essential for many activities. For example, in a modern home, Wi-Fi allows all family members to connect to the internet. In offices and workspaces, Wi-Fi facilitates connectivity between computers, printers, and other devices, supporting a productive and flexible working environment. Public places such as cafes, airports, and libraries also have Wi-Fi networks available to provide customers and visitors with internet access. IoT (Internet of Things) devices like smart thermostats, security cameras, and voice assistants use Wi-Fi to function and communicate.

In Switzerland, Wi-Fi is widely spread in both private homes and public spaces. Swiss internet providers offer Wi-Fi routers and advanced network solutions to ensure stable and fast coverage. Additionally, many public places, including restaurants, hotels, train stations, and shopping centers, offer free or paid Wi-Fi access to enhance the visitor experience. Swiss schools and universities widely use Wi-Fi to support digital learning and research. The availability of high-quality Wi-Fi networks is supported by a robust network infrastructure, enabling residents and visitors to enjoy reliable connectivity wherever they are.
