Vowlan

VoWlan (Voice over Wireless LAN) is the use of a wireless broadband network for the purpose of vocal conversation. In other words, it's just like VOIP but over Wi-Fi.

Vowlan's chief advantages 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.

At this point Vowlan is not popular because of a lack of wireless coverage area. So many vowlan service providers have been distributing mobile phones with dual wireless and GSM mode.

Vowlan is different from 3G in the sense that it uses a wireless internet network (typically 802.11) rather than a mobile phone network .
