Experimental analysis of temporal variations in indoor radio channels at 1.8 GHz

This paper presents the results of a measurement campaign carried out with the aim of analysing the impact of people movement and activities on the indoor radio propagation channel at the frequency of 1.8 GHz. For that, the temporal variations of the channel between fixed terminals are measured in several propagation environments, in which usually different degrees of activity take place, allowing the definition of different canonical environments. From the measured data, the figures and statistical parameters that characterise each of the environments under study are extracted and analysed, in order to be able to associate the results obtained with the density of motion and extrapolate that information to other similar environments. The results can be useful for the design of new systems such as WPANs and for the development of a model that considers both the effects of spatial and temporal variations. © 2002 Wiley Periodicals, Inc.
