This paper analyses the signals propagation characteristics and the most important obstacles that encountered these signals when transmitted from outdoor to indoor (O2I) antennas for the college buildings. These buildings consists of several floors and built in the 3D form according to the real dimensions. In this study, we used measurement analysis and a ray-tracing simulation model approach based on the use of the Wireless InSite (WI) software. The use of different frequencies related to the fifth generation (5G) which are 10, 17, 30 and 60 GHz. According to the results that appeared, it is observed the increase in frequency will lead to an increase in path loss, decrease the received signal strength (RSS). There is an inverse relationship between frequency increase and delay spread and an inverse relationship between frequency increase and received power. In addition, we noticed that there is a direct correlation between frequency increase and path loss, where increasing frequency will increase the path loss, decrease delay spread and received power. Finally, the building’s barriers work on obstructing the direction of the signals path and dispersion of the received signal strength (RSS).
