wireless local area network
C1Technical, Business
Definition
Meaning
A network that allows computers and other devices to communicate and share resources without physical cables, within a limited geographical area like a home, office, or building.
A technology standard (most commonly Wi-Fi) for implementing high-speed wireless data communication between devices over short distances, enabling internet access and network connectivity.
Linguistics
Semantic Notes
The term is highly technical and specific. It is almost always abbreviated to 'WLAN' or, more commonly in general use, referred to by its implementation standard 'Wi-Fi'. The full term is used for precision in technical documentation, standards, and formal business contexts.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Both use the full term and the abbreviation 'WLAN'. 'Wi-Fi' is universally dominant in everyday speech. Spelling follows national conventions (e.g., 'centre' vs. 'center' in surrounding text).
Connotations
Neutral and technical in both varieties.
Frequency
The full term is low-frequency in everyday speech in both regions, being overwhelmingly replaced by 'Wi-Fi'. 'WLAN' is slightly more common in technical manuals and enterprise IT contexts.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calquing like '*беспроводная локальная сеть*' in casual conversation; it sounds overly formal and technical. Use 'вай-фай' (Wi-Fi) or 'беспроводная сеть'. The abbreviation 'WLAN' (pronounced 'вэ-лан' or 'дабл-ю-эл-эй-эн') is also used technically.
Common Mistakes
- Using 'wireless local area network' in casual conversation instead of 'Wi-Fi'.
- Confusing WLAN with WWAN (Wireless Wide Area Network, e.g., 4G/5G).
- Incorrectly capitalising every word in the term when not using it as a proper noun.

FAQ
Frequently Asked Questions
Yes, for all practical purposes. 'Wi-Fi' is the trademarked name for the most common set of technical standards (IEEE 802.11) used to create wireless local area networks. In everyday language, they are synonymous.
A LAN (Local Area Network) traditionally uses physical cables (like Ethernet). A WLAN (Wireless Local Area Network) performs the same function but uses radio waves, eliminating the need for cables.
Use the full term or 'WLAN' in formal technical, academic, or business specification documents where precision is required, or when distinguishing it from other types of networks (e.g., WAN, PAN). In all other contexts, 'Wi-Fi' is perfectly acceptable and expected.
Yes. A WLAN allows devices to communicate and share resources (like printers or files) with each other locally. Internet access requires a router connected to an Internet Service Provider (ISP). The WLAN is the local wireless connection to that router.
