On the Study of Shadow Correlations of Two Radio Frequencies in an Urban Environment

We present the results of an extensive, high spatial density measurement campaign made for investigating the shadowing correlations on two different frequency bands, namely 485MHz and 2600MHz in an urban propagation environment. In particular, we report results using different analysis procedures and tools. Our results show that the signal detector has only a small impact on the extracted data, given that the fast fading is correctly averaged out. Moreover, we extract the main parameters of shadow correlations. Finally, we report a preliminary comparison between a suburban and an urban propagation environments by comparing the parameters of the fitted variograms.
