Abstract

Analytical model and calculations of voice transmission over the wireless IEEE 802.11b/g networks which are using PCF coordination functions are proposed. Using this model, some wireless networks characteristics are unrevealed, like their efficiency to provide voice over IEEE 802.11b/g networks when different voice codecs are used. What is more, wireless network capacity for calls is calculated for different types of voice codecs. These results are compared with the same network parameters but DCF coordination functions implemented. It is found that VoIP calls capacity could be two times bigger with higher network bandwidth compared with the results of lower bandwidth from the references’ calculations. It is because of the usage of PCF coordination function in 802.11b/g WLANs. Ill. 7, bibl. 7 (in English; summaries in English, Russian and Lithuanian).
