Measurement and modelling of an UWB channel at hospital

Abstract

This paper describes the results of an ultra wideband (UWB) channel measurements and modelling from 3.1 to 6.0 GHz carried out at the Oulu University Hospital. Mainly line-of-sight (LOS) channels were measured having transmitter-receiver separation from 3 to 6 m. The modelling is done in time domain and in frequency domain, and the results are compared with. Channel parameters that are corresponding to the modified Saleh-Valenzuela (SV) model in time domain and autoregressive (AR) model in frequency domain are extracted from the measurement data. Also, delay spreads and path losses are examined. In the study, the effect of the huge frequency diversity over the UWB band on the path loss is pointed out.
