Abstract—A comparison between the performance of C-band and mmWave band with different range of frequencies has been presented in this paper. These frequencies are included 3.5 and 5.2 GHz for C-band, whereas they involved 38 and 42 GHz for mmWave band. This comparison has been accomplished with two different scenarios including Line-of-Sight (LOS) and non-Line-of-Sight (NLOS). Statistical parameters of channel propagation characteristic including delay spread, path loss and received power are inspected in this paper. Furthermore, the impact of building material on the signal penetration has been considered as function of frequency. A Comparative Study of Wireless Propagation Simulation has been carried out using Wireless InSite software-based Ray tracing model. Using this software, the simulated results have been analyzed. Of particular note is the inverse relation between delay spread and separation distances with values in mmWave are much smaller than that in C-band. In contrast, there is a direct correlation between the path loss and the separation distance has been found, where the path loss value in mmWave is much higher than C-band. A substantial contribution has been proposed to enhance the coverage area of mmWave band as an attempt to make it closer to the C-band performance. This study would be considered for designing and implementation of smart modern buildings. In particular, when technology trends to move toward the next Fifth Generation (5G) communication system with increasing the coverage area of signals particularly for indoor communication aspects.
