As wireless networks becoming more accessible, Voice over Internet Protocol (VoIP) in Wireless Local Area Network (WLAN) is becoming an interesting application service which can provide low-cost real time voice service to mobile users. VoIP capacity which is the maximum number of simultaneous voice connections that can be supported in an IEEE 802.11 WLAN, is an important issue. The authors analyzed the theoretical capacity of VoIP traffic in IEEE 802.11 WLAN and derived capacity formulations for Constants Bit Rate (CBR) and Variable Bit Rate (VBR) VoIP traffic in no collision situation and collision situation. Using those formulations they computed the voice capacity.
