This paper presents and compares two candidate large-scale propagation path\nloss models, the alpha-beta-gamma (ABG) model and the close-in (CI) free space\nreference distance model, for the design of fifth generation (5G) wireless\ncommunication systems in urban micro- and macro-cellular scenarios. Comparisons\nare made using the data obtained from 20 propagation measurement campaigns or\nray-tracing studies from 2 GHz to 73.5 GHz over distances ranging from 5 m to\n1429 m. The results show that the one-parameter CI model has a very similar\ngoodness of fit (i.e., the shadow fading standard deviation) in both\nline-of-sight and non-line-of-sight environments, while offering substantial\nsimplicity and more stable behavior across frequencies and distances, as\ncompared to the three-parameter ABG model. Additionally, the CI model needs\nonly one very subtle and simple modification to the existing 3GPP\nfloating-intercept path loss model (replacing a constant with a close-in free\nspace reference value) in order to provide greater simulation accuracy, more\nsimplicity, better repeatability across experiments, and higher stability\nacross a vast range of frequencies.\n
