Empirical modeling study demonstrates accurate path loss predictions across 2 to 37 GHz in street microcell environments, indicating improved radio network planning for 5G systems.
A path loss model based on the Rec. ITU-R P.1411 model, which can cover the frequency range from microwave to millimeter-wave bands, is presented. The path loss characteristics are analyzed on the basis of measurement results obtained using the 2 to 37 GHz band in street microcell environments. It is clarified that the characteristics depend on distance from transmitter to intersection and frequency dependency. By taking these dependencies into account, the proposed model can decrease the root mean square error of prediction results to within about 5 dB in the 2 to 37 GHz band.
