Evaluating the effects on enhanced intersystem connectivity

In English Future mobile terminals will be able to use several types of wireless systems and have the possibility to change between different operators, while maintaining there original connection. This will impact the operators way of conduct business locally as well as globally. The different wireless systems will form hierarchical networks, where the systems have different coverage areas and bandwidth offerings. In this paper a model of hierarchical networks is presented, consisting of different kinds of wireless systems, such as WLAN and UMTS. The analyse of the hierarchical model shows that an increasing coverage area of any of the networks with higher bandwidths, will manifold the usage of these systems. Results from the study also show that as the number of applications and services increase, there will be a distinct shift towards hot spot systems at the expense of the wide area coverage systems. However, this will also dramatically increase the number of intersystem handovers, in both directions.
