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.
