Abstract :
Wireless local area network (WLAN) has been widely deployed in recent several years. Voice over IP over WLAN, or called voice over WLAN (VoWLAN or wi-fi phone), is regarded as one the killer applications for public and private WLANs. However, VoWLAN suffers from a number of technical challenges that make the commercial and large VoWLAN services difficult to provide. In this paper, we brief the current technology status and summarize research challenges of VoWLAN services.
