WLAN
Definition
Wireless Local Area Network, generally a network based on IEEE 802.11.
Detailed explanation
WLAN means Wireless Local Area Network and generally refers to Wi-Fi networks based on IEEE 802.11 standards. Windows exposes WLAN interfaces through its networking stack while the adapter driver and radio firmware manage scanning, association, encryption, and power. Bands, channels, protocols, and regulatory domains constrain operation. An access point advertises capabilities and security suites, and a client negotiates a subset supported by both sides. Roaming, MLO, WPA authentication, channel width, and power saving involve cooperation between Windows, driver, radio firmware, access point, and regional policy.
Where you are likely to see it
This term is most often visible in adapter properties, wireless settings, connection diagnostics, or a network-driver release note. The definition above gives the short meaning; the detailed explanation describes the term's role in the operating system and hardware stack.
Adapter models, radio standards, and operating-system versions provide the context for interpreting the label. This glossary is informational and does not provide repair, installation, or technical-support services.
