Wireless LAN (WLAN)
Wireless LAN (WLAN) is a local radio network based on the IEEE 802.11 family of standards, through which devices connect to the network without a cable.
It operates in frequency bands around 2.4, 5 and 6 gigahertz.
Wireless LAN is practical where there is no network cable, for example in shop windows, on pillars or for short-term installations. E-paper signs and many small players rely entirely on radio. In companies, screens should get their own wireless network or network segment, separate from tills, office and guests, secured with current encryption such as WPA2 or WPA3.
Radio is more prone to interference than cable: walls, glass, metal and many neighbouring networks weaken reception, and large downloads take longer. Guest networks with a login page or with devices isolated from one another are usually unsuitable for players. If the wireless password is changed, all screens lose their connection until someone enters the new password on the device. For screens with large videos, a cable is the better choice wherever possible.
