User perception of QoS and economics for a WiMAX network in a backup scenario

WiMAX and WiFi are considered as complementary technologies for serving broadband users in the last mile, despite their differences in technical terms, regulatory constraints and business models. Therefore the scenario of using WiMAX network as a backup in case of WiFi networks failure is a realistic one. This paper provides an example for evaluating the effects of such scenario by considering two main aspects: user-perceived quality of service and service provider revenue. Both aspects are analyzed using a combination of analytical approach, proposed pricing approach per application and simulations for a sample scenario, providing methodology for further development of backup approaches for coexisting wireless networks.
