This paper evaluates MIMO radio channel measurements at 3.8 GHz, conducted in various urban microcellular environments in the city of Louvain-la-Neuve, Belgium. Large-scale parameters, such as shadow fading, delay and angular spreads as well as dense multipath power are extracted and compared with values provided by existing models. A joint specular-dense multipath cluster-based model is then parametrized from the experimental data, detailing cluster spread and correlation properties.
