Abstract: As a real-time application, the VoIP phone technology based on IEEE 802.11 wireless LAN has its special needs. By analyzing the MAC process of WLAN and the technologies related VoIP, transmission delay, jitter and drop rate are also the main respects influencing the MOS of VoIP on WLAN. In addition, the problems which exist on WLAN about VoIP and the answers to these, such as QoS and mobility are analyzed in this paper.
