Performance Evaluation of Wireless IP Telephony (W-IPT) over Wi-Fi Networks

摘要

As one of the fastest growing voice service technologies, IP Telephony is currently the greatest benefactor of IP Convergence. Apart from the cost and management benefits of a converged network, the exciting array of productivity enabling applications such as unified messaging, collaboration, and presence services within an IP Telephony infrastructure are driving this rapid growth. Wi-Fi, on the other hand, is the widest deployed technology for indoor Internet access. It is therefore the default candidate for enabling wireless IP Telephony (W-IPT). The study aims at assessing the performance of W-IPT over Wi-Fi networks. In particular, the paper describes an experiment that was carried out on a running network at a university campus. The results shed some light on the readiness of Wi-Fi networks to embrace this fast emerging technology.
