Radio channel propagation measurements using a multiband agile chirp sounder

A newly developed multi-band FMCW channel sounder at Durham University was used to perform measurements in the ISM bands in three test beds and on-body measurements in the 60 GHz band. The sounder uses an agile frequency synthesiser to sweep across its bandwidth which enables real time measurements in comparison to the Vector Network Analyser. In this paper we present the estimated rms delay spread for the on body configuration and in the test bed environments. We also present estimated path loss coefficients in an office environment and a semi-shielded environment.
