1. A method for adapting a radio network model to conditions of a real radio network comprising the steps of: defining different measuring positions; carrying out measurements of variables at said different measuring positions, thereby generating measured data; providing position-dependent modelling values, using said measured data for said modelling values from the real radio network obtained at said measuring positions; setting a fine grid in a radio cell, defining small area portions, wherein one or more of said modelling values is attributed to each area portion by said radio network model; and setting mathematical operations for modifying said modelling values of all area portions of said fine grid by adapting said modelling values to said measured data, wherein said mathematical operations are for each area portion directly dependent on said measured data and said position of said respective area portion.
