Comparative Study of Improvements in the Quality of Radio Links and Call Drop Rates Based on Variations of Empirical Radio Propagation and Number of Base Stations

This study aims to get the best performance of cellular communication based on variations in empirical radio propagation models and the number of base stations (BTS) in urban areas. The model is designed and simulated by using programming software. The observed performance parameters are the quality of the radio link and drop call. Simulation results found that the increase in base stations and mobile stations (MS) antennas height resulted quality increment of the radio link and decrement of drop call rate for all empirical models. Likewise, an increase in the number of BTSs to four in system, exerted quality improvement of radio links and decrement on drop call rate. It was also found that each increase in antenna height for the Hata radio link model produces zero dropped call as the quality of the Hata radio link is above the threshold, even when the antenna height is at the lowest.
