Heterogeneous networks that contain overlapping coverage of several wireless access technologies enabling better spectrum efficiency and utilization are becoming common. In this work we focus specifically on WiMAX technology running at the outer cell and Wi-Fi technology applied in the inner cells. We define a system-wise entity that is activated when a user is in an area with over-lapping access technologies and needs to decide what is the best technology to be used, where the entity performs technology selection in order to optimize the overall system performance metric in terms of throughput and capacity limitation. Our simulation results validate the efficiency of our method and show that it is also applicable to other combinations of access technologies.
