In this paper, we empirically explore voice communication

over IEEE 802.11 networks (VoWiFi). The objective is

to understand the limitations of the current WiFi network for

VoWiFi deployment. Our experiment finds two major problems

of VoWiFi: unstable and excessively long handoffs and unpredictable

occurrence of bursts. We also discuss several other

minor factors that could hinder VoWiFi deployment, such as

network capacity, fairness, and interference susceptibility. Finally,

we describe the scenarios where VoWiFi could be used. We

conclude that VoWiFi is feasible if used moderately, with low

mobility and good signal strength.
