A Multiplex-Multicast Scheme That Improves System Capacity of Voice-over-IP on Wireless LAN by 100%
Overview Voice-over-IP (VoIP) is an important application on the Internet. With the emergence of WLAN technology and its various advantages compared with the traditional wired LAN, it is fast becoming the "last-mile" of choice for the overall Internet infrastructure. This paper considers the support of VoIP over 802.11b WLAN. It shows that although the raw WLAN capacity can potentially support more than 500 VoIP sessions, various overheads bring this down to only 12 VoIP sessions when using GSM 6.10 codec. A novel multiplexing scheme for VoIP is proposed which exploits multicasting over WLAN for the downlink VoIP traffic.
