The trend of exchanging information data will continuously increase due to the rapid development of mobile communication networks. The new fifth-generation (5G) technology is designed to support the ever increasing demand for internet traffic volume over wide coverage ranges. This paper focuses on the studies of empirical path loss prediction models for network planning of 5G mobile communication systems. The relationship between path loss and other wireless propagation parameters such as transmitter-receiver antennas separation distance, antenna heights, operating frequency are presented to improve the performance optimisation of wireless networks. The data provided in this paper was analysed in MATLAB computer program to predict signal path loss; estimate radio coverage; avoid interferences; and determine received power level. The results based on the studied model showed that the propagation path loss decreases in accordance with the increase in base station tower antenna height. Okumura model is the most suitable model for short-haul applications in 5G radio network communication.
