I. A. Belozertsev · Proceedings of Telecommunication Universities · 2022
With the increasing demands for mobility and guaranteed quality, new technologies with new capabilities, such as 4G and 5G networks, have appeared to meet the needs of users. Indeed, 4G networks are constantly striving to improve the services offered and guarantee a certain level of quality of service (QoS). The 5G standard promises ultrafast speeds and an end to congestion in mobile networks. This technology is expected to revolutionize mobile networks and create new economic opportunities. In this context, the purpose of this article is a detailed comparison of 4G and 5G technologies. Thus, we outline the various characteristics of 4G systems, that is, their contribution and their behavior in terms of maintaining QoS. We will also evaluate the efficiency of virtualization and mobile edge computing in modern networks.
