VoWiFi - Computer Definition
The transmission of packet voice over an IEEE 802.11 wireless LAN (WLAN). VoWiFi takes advantage of the bandwidth offered by 802.11g (54 Mbps) and 802.11n (108 Mbps) to support voice over Internet Protocol (VoIP) over networks of fast Layer 2 Ethernet switches controlling handoffs among large number of thin access points (APs). Quality of service (QoS) issues were resolved in 802.11e (2005) through a coordination function that provides a station with high priority traffic such as voice with more frequent network access than a station with low priority traffic such as e-mail. Furthermore, the station with the high priority traffic is granted a longer transmit opportunity. See also 802.11, 802.11e, 802.11g, 802.11n, AP, bandwidth, handoff, QoS, thin AP, VoIP, and WLAN.
