article description
An indoor propagation prediction for personal communication systems is demanded for modern wireless services. There are two main general approaches for indoor propagation modeling: empirical and deterministic. Both of them have their advantages and disadvantages. Novel semi-deterministic approach to modeling of propagation of electromagnetic waves inside buildings, which combines both deterministic and empirical approaches is introduced. It is based on ray-launching technique, Monte Carlo method and statistics. The model is very fast and requires only easy to obtain inputs. The model is capable of wide-band parameters prediction as well. A description of the new approach together with firs results of the model implementation and its evaluation by measurements are presented.
