Correlation of Pathloss in the Okumura-Hata Model with the COST 231 Model in Simulation-Based Cellular Communications

The quality and continuity of communication links via air transmission media are essential in cellular communications in urban, suburban, and rural areas. The magnitude of path loss that occurs along the channel affects the quality and continuity of communication. Therefore, the magnitude of these losses greatly determines the magnitude of the physical parameters, distance, and frequency that will be used in designing a cell. The Okumura-Hata empirical model and the COST 231 model are used to determine the magnitude of losses along the line so that the best position and direction of the antenna for a cell can be determined. These two models are simulated with the software on a computer for various frequencies, antenna heights, and distances. At distances of 1, 2, 3, 4, and 5 km, both models have a linear regression line with a correlation coefficient of 1, indicating a very strong correlation level between the two models.
