Radio Propagation Measurements and Analysis with Clutter Loss in Urban and Suburban Environments at 3.7 and 4.9 GHz

This work aims to present and analyze clutter loss propagation measurements in 3.7 and 4.9 GHz, which are bands of interest for communications and next-generation networks. The clutter loss model has been widely debated in the International Telecommunication Union (ITU) due to its importance for coexistence studies, and its applicability for bands below 10 GHz in different environments, is currently being discussed. In this work, a narrowband signal measurements campaigns were carried out in dense urban and suburban environments in Rio de Janeiro, Brazil, to calculate the path loss propagation with the aim of clutter loss characterization in these scenarios and evaluate the applicability of the clutter model and its limitations. This information will be useful for the regulatory process, including the evaluation of the prediction models used in Anatel’s coexistence studies.
