Intelligent Ray Launching Algorithm for Indoor Scenarios

Abstract

This article describes the indoor IRLA (Intelligent Ray Launching Algorithm), which originates from an efficient outdoor propagation prediction model. Implementation and validation are given in detail. An indoor office scenario is selected and simulations via the IRLA model and two other reference models have been performed. Predictions are analysed and recommendations are given. Results show that the indoor IRLA model is suitable for indoor wireless network planning and optimisation process.
