Capacity analysis and resource management of an integrated WiMAX & Wi-Fi access system for VoIP

Huanxu Pan; Satoru Yamano; Daisuke Kawasaki; Hideaki Tani

In this paper, we give a quantitative evaluation on the effect of integrating WiMAX and Wi-Fi, as compared to the case of separate WiMAX and Wi-Fi systems, on the system capacity with QoS being considered. We focus particularly on the VoIP traffic aspects of the system. Based on this capacity evaluation, a cost analysis is further presented. We also propose and analyze a resource management scheme on Wi-Fi to WiMAX handover.
