The increasing demand for high speed data and multimedia services forces indoor radio communications to exploit new, almost fully available bands. Among the possible radio spectrum parts, the 60 GHz band seems to provide a good solution to move on. Thus, the paper deals with mobile radio channel characterization in indoor environment at 60 GHz; this is accomplished by means of an electromagnetic computer model, based on a fully 3D ray tracing approach. The channel has been characterized both in terms of radio coverage and of radio signal statistics, evaluating the best fitting cumulative distributions, the relationship between their parameters and the corresponding environment characteristics and addressing the improvements achievable by means of space diversity techniques.RésuméLa demande croissante de services à haut débit et multimédias oblige les communications radio intraimmeubles à exploiter de nouvelles bandes de fréquences presque inutilisées. Parmi les portions de spectre possibles, la bande 60 GHz semble convenir le mieux. Cet article traite de la caractérisation de la propagation intra-immeuble à 60 GHz en utilisant un algorithme de tracé de rayons tridimensionnel. Le canal radioélectrique a été caractérisé soil par la couverture radio soil par la statistique de I’intensité du signal reçu, en évaluant les distributions cumulatives de meilleur ajustement et les relations entre leurs paramètres et les caractéristiques de I’environnement, et en analysant les avantages réalisables en utilisant des techniques de diversité.
