N2 - In this paper, by using a dual-band channel sounder equipped with omnidirectional antennas, we have measured and investigated the propagation parameters including path loss and shadowing at 1.79 and 4.9 GHz in the typical non-line-of-sight (NLOS) urban macrocell (UMa) scenario. Two different large-scale channel models, the alpha-beta-gamma (ABG) model and the close-in model with a frequency-weighted path loss exponent (CIF), are derived according to the channel measurement data. Finally, we compare the parameter values, shadow fading (SF) standard deviations, and prediction errors of the two models, and evaluate the accuracy and sensitivity with respect to the measurement data. The numerical results show the improvement in the channel fading estimation of the CIF model compared with the ABG model.
