1. A system for radio network planning, comprising: at least one grid generator, arranged for generating a map of pixels, each pixel representing a radio network area having at least one of a plurality of radio network input parameters, the parameters representing a radio network having at least one cell and at least one user, a Monte Carlo analysis module, comprising i) a snapshot generation module, arranged for generating a plurality of snapshots, each snapshot comprising the map of pixels, wherein for each snapshot and for each pixel a statistical realization is drawn from a distribution function relating to at least one of the input parameters, ii) a snapshot evaluation module, arranged for establishing radio network performance parameters for each pixel of the plurality of snapshots, iii) a sub-snapshot generation module, arranged for generating at least one sub-snapshot for each evaluated snapshot result, wherein a statistical realization is drawn from a distribution function relating to fast fading within the snapshot, and iv) a sub-snapshot evaluation module for establishing high speed downlink packet access (HSDPA) performance parameters based on the sub-snapshot, wherein the sub-snapshot evaluation module comprises a scheduler sub-module, which is arranged for scheduling a user according to a scheduling criterion.
