Estimation of Parameters of 5G Network Dimensioning

1. Introduction

Cellular mobile networks are in service for more than three decades. In the past, these networks were designed for voice communications. Later data communications services were started, but they were supported as value added services (e.g., Internet browsing). However, in Long Term Evolution (LTE) and then in fifth-generation (5G), data communications and high speed streaming are the main trends over the cellular networks (Sharma et al., 2020). In order to make the emerging applications more convenient for the users, a significant shift has taken place in the development of 5G mobile networks (Lien et al., 2017). Third Generation Partnership Projects (3GPP) have developed all these new standards over the last decade. 5G is going to be a hybrid of optical and wireless networks (Sharma et al., 2018). In order to meet the extremely high data rates, high reliability and ubiquitous coverage while maintaining the cost effectiveness, its architecture has to be hybrid. Thus the dimensioning of 5G will be significantly different from the previous generations of mobile communication systems.
