Abstract
The popular technologies Wi-Fi and WiMAX for realization of WLAN and WMAN respectively are much
different, but they could compliment each other providing competitive wireless access for voice traffic. The article
develops the idea of WLAN/WMAN (Wi-Fi/WiMAX) integration. WiMAX is offering a backup for the traffic
overflowing from Wi-Fi cells located into the WiMAX cell. Overflow process is improved by proposed
rearrangement control algorithm applied to the Wi-Fi voice calls. There are also proposed analytical models for
system throughput evaluation and verification of the effectiveness using WMAN as a backup for WLAN overflow
traffic and the proposed call rearrangement algorithm as well
