WLAN, short for Wireless Local Area Network, is a local communication network that uses radio waves to connect devices such as computers, smartphones, tablets, and printers without the use of cables. This technology allows devices to connect to the internet and communicate with each other within a limited area, such as a home, office, or campus. WLANs are based on the IEEE 802.11 network standards, commonly known as Wi-Fi, which define the protocols for wireless data transmission.

In everyday life, WLANs are used to connect a variety of devices wirelessly. For example, in an office, a WLAN allows computers, printers, and VoIP phones to communicate without the need for physical cables, facilitating mobility and flexibility in workspaces. In the home, a WLAN enables family members to access the internet from laptops, tablets, smart TVs, and IoT devices like smart thermostats and security cameras.

In Switzerland, the use of WLAN is extremely widespread due to the country's robust telecommunications infrastructure. Swiss providers such as Swisscom, Sunrise, and Salt offer advanced wireless network solutions for homes, businesses, and educational institutions, ensuring high coverage and speeds.
