Advanced modelling of intelligent walls for indoor smart environments

The paper deals with the modelling of Intelligent Walls, i.e. building walls that are capable of providing real time control of propagation in indoor environments. The Intelligent Wall is a metalized wall equipped with an Intelligent Wall Unit allowing the wall to change its electromagnetic properties in real time. The wall parameters are pre-calculated using CST Microwave Studio and then employed in a radio-wave propagation model based on the modified Ray-Launching method. The crucial part of the algorithm, the interaction between a ray and an Intelligent Wall is explained in detail. The structure of the Intelligent Wall Unit is briefly described and coverage calculations in a sample scenario are presented.
