In this paper, a comparative study between different indoor path loss prediction models is conducted. The investigated models include averaged wall loss model (AWM), single slope model (SSM), linear attenuation model (LM), two slope model (TSM), partitioned model (PM), and Motley-Keenan model (MKM). The models were tested in a simulated environment of the 3rd floor of Chesham building, the University of Bradford, a different set of frequencies were used including 28 GHz, 60 GHz, and 73.5 GHz, TSM shows the best performance, both AWM and MKM tend to have a similar performance at millimetrefrequencies, both models’ prediction for corridor and LOS regions are pessimistic while TSM, SSM, and LM have better estimations in these regions.
