The performance of a mobile network is essentially based on the capacity of its radio access technology. A mobile network is spatially and functionally distributed. Its subsystems are in constant interaction with each other and with their geographic environment. Finding an appropriate approach to evaluate the capacity of a radio access technology with respect to a wide range of parameters (radio signal quality, quality of service, user mobility, and network resources) has become increasingly important in today’s wireless network planning. Traditional mathematical and statistical modeling techniques do not satisfy the requirements of such a complex process where spatial data is of fundamental importance. In this paper, we propose a model-based geo-simulation approach in order to assess the capabilities of the 1xEV-DO radio access technology. Results are expressed in terms of signal quality (C/I and EC/I0) for the requested services and applications.
