The aim of the study was to examine the factors influencing call-drops among wireless cellular network users in Ghana. A total of 1109 wireless cellular network users participated in the study. Exploratory and confirmatory factor analyses were used to find out the latent factors influencing the call-drops among wireless cellular network users in Ghana. The results of the exploratory and confirmatory factor analyses revealed eight-factor constructs. Among these factors, limited cell towers, cell tower overload, and general power problems were found to be the highest contributory factors. The combined three factors accounted for almost 57% of the total variance. The study's results reveal that network factors play a major role among the factors influencing call-drops in Ghana. This implies that in dealing with call-drop problems in Ghana, policymakers, regulators, and stakeholders should pay attention to the network factors of wireless cellular networks.

The increasing rate of call-drop among wireless cellular networks has become a headache for subscribers of mobile voice networks in Ghana. Despite the many studies that have been carried out on call-drop, most of them have failed to examine call-drop probability rates, a key metric of tackling the issue of call-drop. This study combines the probability distribution function of call-drop and maximum likelihood estimator to estimate call-drop probability rates among the wireless cellular networks in Ghana. The call-drop of the networks was, first of all, fitted to a probability distribution. The call-drop probability rate was then estimated using the maximum likelihood estimator of the fitted distribution. The call-drop probability distribution of Airtel-Tigo, Vodafone, and Glo follow the Geometric probability distribution, while that of MNT follows the Negative Binomial probability distribution. The call-drop probability rate of MTN is 7.6%, Vodafone is 3.3%, Airtel-Tigo, and Glo is 3.0%. These call-drop rates are found to be outside the prescribed NCA's acceptable limit of less than 3 %.
