It has been suggested that this article be merged into Wi-Fi calling. (Discuss) Proposed since May 2024.

Voice over wireless LAN (VoWLAN), also voice over Wi‑Fi (VoWiFi^[1]), is the use of a wireless broadband network according to the IEEE 802.11 standards for the purpose of vocal conversation. In essence, it is voice over IP (VoIP) over a Wi-Fi network. In most cases, the Wi-Fi network and voice components supporting the voice system are privately owned.^{[citation needed]}

VoWLAN can be conducted over any Internet accessible device, including a laptop, PDA or VoWLAN units which look and function like DECT and cellphones. Just like for IP-DECT, the VoWLAN's main advantages^{[citation needed]} to consumers are cheaper local and international calls, free calls to other VoWLAN units and a simplified integrated billing of both phone and Internet service providers.^{[citation needed]}

Although VoWLAN and 3G have certain feature similarities, VoWLAN is different in the sense that it uses a wireless internet network (typically 802.11) rather than a cellular network. Both VoWLAN and 3G are used in different ways, although with a femtocell the two can deliver similar service to users and can be considered alternatives.^{[citation needed]}
