Novel Approach to Indoor Propagation Modeling
Abstract
An indoor propagation prediction for personal communication systems isdemanded for modern wireless services. There are two main generalapproaches for indoor propagation modeling: empirical anddeterministic. Both of them have their advantages and disadvantages.Novel semi-deterministic approach to modeling of propagation ofelectromagnetic waves inside buildings, which combines bothdeterministic and empirical approaches is introduced. It is based onray-launching technique, Monte Carlo method and statistics. The modelis very fast and requires only easy to obtain inputs. The model iscapable of wide-band parameters prediction as well. A description ofthe new approach together with firs results of the model implementationand its evaluation by measurements are presented.
