Narrowband as well as wideband measurements ha,ve been performed in various indoor and outdoor environments in order t o enable the development of reliable prediction models for 60 GHz radio channels. In addition, results of deterministic modelling on the basis of geometric raytracing have been compared with measurement results, showing that simple ray-tracing can be used t o estimate both the narrowband and wideband characteristics of a 60 GHz radio channel. This paper reviews the measurement and modelling activities performed by various research i nst it Utes
