Comparison of measurements and simulations in indoor environments for wireless local networks at 60 GHz

Abstract

Indoor wireless local networks (WLAN) development in the millimetre band gives new perspectives, which are very promising in terms of announced data rate and offered services. Nevertheless strong free space attenuation as well as pieces of furniture and wall attenuations result in difficult propagation conditions. A French research project (RNRT COMMINDOR) has been set up to study and design new high data rate (155 Mbit/s) radiocommunication systems at 60 GHz in an indoor environment. SIRADEL takes part in this project by modelling the propagation phenomenon thanks to a ray-tracing tool associated to the Uniform Theory of Diffraction (UTD). Simulations are then compared to measurements realised within the framework of this project by the LCST Laboratory of INSA Rennes. The good behaviour of the propagation model is analysed for LOS and NLOS situations.
