Analysis of Path Loss in Narrowband for Millimeter-Wave Measurements Over a Frequency Range of 27 GHz to 29 GHz at PUC-Rio Campus, Brazil

Abstract

This paper aims to evaluate the accuracy of Path Loss mathematical models using measurements taken at the Pontifícia Universidade Católica do Rio de Janeiro - PUC-Rio by comparing them with theoretical models such as the CI (Close-In) model and the Alpha-Beta model. Outdoor measurements were conducted with the transmitter installed on the Leme building at the PUC-Rio campus in Brazil. In total, 23 reception points were evaluated for 27−29GHz frequencies. Afterward, Path Loss was plotted as a function of distance for both theoretical models and empirical data. Finally, Root Mean Square Error (RMSE) was calculated to assess the efficiency of theoretical models regarding empirical measures.
