This work analyzes the voice communication over IEEE 802.11
networks (VoWiFi). It empirically characterizes the transmission
problems of VoWiFi and describes scenarios where
it could be used over the existing network technologies. The
two major problems found were: the excessively long handoffs
and the occurrence of bursts. We conclude that is
feasible to use VoWiFi if, during a voice call, mobility is
kept low, signal strength is high enough and the network
capacity is not exceeded.
