WIRING LAYER
Engl. cabling layer. Cabling is not provided for in the ISO layer model; connectors and interfaces are defined on ISO layer 1, but not cables and lines. In order to nevertheless classify cabling in the model, it is assigned the fictitious "layer 0".
WLAN
Abbreviation for "Wireless LAN", collective term for data networks with data transmission via radio. The most important international representatives are standardized according to IEEE 802.11.
