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.
