VoWF (Vo-IP over Wi-Fi)
Wireless telephony has become very popular in the past few years. However, the high costs of cellular systems make it necessary to find different technologies that can reduce the prices while keeping the efficiency and mobility. For this reason the authors explored the advantages and disadvantages of VoIP over Wi-Fi (VoWF), which means using wireless networks based on the IP protocol (like internet) to transmit voice. In this paper they tested the performance of VoWF using Skype and X-Lite which are VoIP softwares and demonstrated to have similar behavior.
