Radio network modeling and performance evaluation for UMTS,ng point for the subsequent developments. We first outline the general structure of cellular wireless communication networks and the special nature of the radio channel in Sec. 2.1. In Sec. 2.2, we explain the principles upon which communication over the . radio interface is built, as well as their

Interference-coupling complementarity systems,ct dimension and have a built-in notion of soft capacity and load control. With the new models and methods, we can evaluate all relevant indicators of network performance for a given snapshot at low computational cost.

SKIFF

Expected-interference-coupling estimates for network performance,n the expected performance for random snapshots. The coupling matrices thus have to be considered random variables subject to a probability distribution induced by the distribution on snapshots, and we are interested in the stochastics of the performance indicators.

Conclusion,ntinuously to current traffic and conditions, there is no simple formula to determine the performance of a network configuration. Already a rough dimensioning requires detailed information on user location, traffic characteristics, channel models, and equipment. Only time-consuming simulation can gi
