WLAN stands for Wireless Local Area Network. It is a local area network that does not rely on wired Ethernet connections. WLAN can be an extension or alternative to an existing wired network.

Because the wireless signal is broadcast so that anyone nearby can share it, several security measures are required to ensure that only authorized users can access your WLAN. This is usually encryption.

A WLAN signal can be broadcast to cover an area of varying size, from a small office to a large one. This is related to the capacity of the modem that distributes the signal or similar devices that emit the signal.
