Novel Approach to Indoor Propagation Modeling

Abstract

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.
