Investigations on radio propagation channel measurements at 2.2 GHz and 3.5 GHz for the fixed wireless access in an urban area

Abstract

Within a competitive context the wireless local loop is emerging as an alternative to the traditional wireline network. This solution is attractive because of its low capital cost and its flexible deployment. Nevertheless a propagation channel study has to be performed so as to develop specific engineering tools and propagation models. This paper presents wideband propagation measurement results carried out in Mulhouse in a small cell environment at 2.2 GHz and 3.5 GHz. Under different propagation scenarios, the propagation channel is characterised in terms of path loss and wideband selectivity parameters. Because of the experimental setting, the influence of the receiving height, the frequency and the receiving antenna pattern on the deviations of the path loss and the selectivity parameters have been investigated.
