Voice over Wireless Data Networks
G. Adam Covington,
Abstract
As wireless technology becomes increasingly available it only makes
sense that applications like Voice over IP (VoIP) would be
implemented. The merging of two areas, VoIP and wireless networks,
has created Voice over WiFI (VoWiFi). Problems with VoIP are not
only ported to wireless networks, they are also magnified. Mobility
is an issue with wired networks, however wireless networks require
mobility on a much larger scale. This paper focuses on some
underlying issues of VoIP and VoWiFi. It also presets some
background on protocols and codecs used with telephony data.
