Multidimenzional decission function on access technology

Wireless data services, boosted by the massive use of popular Internet-based services such as email, WWW, etc., wireless wideband networks capable of supporting mobile multimedia services have attracted increasing intention in last few years. An important requirement has been postulated for these wideband services — they cannot be substantially more expensive than the voice services offered today. This paper presents analysis of mobile wireless networks: HSPA and WiMAX made in order to compare multidimensional acceptance of investments in these technologies. Based in model in OPNET Modeler, the simulation and testing of different typical signals in these networks are made, where the Core network is taken as the same for both networks in order to neglect its influence on QoS results. The simulation results are than used as one dimension, QoS in multidimensional function of investment process. Also, business analysis of investments into these networks is also done, and 5-year investment value is taken as another dimension. The third dimension is taken as market acceptance of these technologies, which makes them cheaper or faster to implement. The result is multidimensional function which enables the operator to direct its investment process based on the same multidimensional space. It is shown that operator can decide to deploy one or another technologies based on its preferences.
