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

Within a competitive context the wireless local loop is emerging as an alte rnative to the traditional wireline network. This solution is attractive be cause of its low capital cost and its flexible deployment. Nevertheless a p ropagation channel study has to be performed so as to develop specific engi neering tools and propagation models. This paper presents wideband propagat ion measurement results carried out in Mulhouse in a small cell environment at 2.2 GHz and 3.5 GHz. Under different propagation scenarios, the propaga tion channel is characterised in terms of path loss and wideband selectivit y parameters. Because of the experimental setting, the influence of the rec eiving height, the frequency and the receiving antenna pattern on the devia tions of the path loss and the selectivity parameters have been investigate d.
