| Abstract | Telecommunication systems continue to grow tremendously in the past few decades. This growth was driven by the massive amounts of capacity required for exploiting mobile traffic. Despite the increase in performance and Quality of Service (QoS) provided by mobile telecommunication systems during the past decade, mobile operators competitively kept upgrading cellular networks' architectures and technologies. Hence, following the deployment of the Third Generation Partnership Project Long-Term Evolution (3GPP LTE) as Release 8, the work started on the development of fourth-generation (4G) systems. Thus, LTE systems recently swept the market in order to provide even more integrated services, such as High Definition (HD) video streaming, videoconferencing, and many other end-to-end services. Since 2010 the 3GPP's efforts have been devoted to the standardization of LTE-Advanced (also known as LTE-A) system, including releases 10, 11, and 12 in the objective to meet all the International Mobile Telecommunications-Advanced (IMT Advanced) requirements set by the International Telecommunications Union (ITU). However, more advanced technologies are still needed. Therefore, research on the fifth-generation (5G) systems has recently started while believing that the new overpowering mobile generation 5G will enable not only people but also any device to be connected at all times and places with a better Quality of Experience (QoE) for end users. With 5G researchers aim to fulfill the dream of ubiquitous wireless connectivity by ensuring the concept of the Internet of Things (IoT) that will convert our homes and cities into smart ones. This generation is required to have Reconfigurable core network, integrating a Multitechnology convergent core including services based on an All-IP Platform that supports an important number of simultaneous connections. The objective of this chapter is to provide an overview of all new telecommunications technologies, assess their importance, particularly their derived uses, and analyze the technical and technoeconomic constraints related to their deployment. This chapter provides a comprehension discussion on the key enabling technologies for 4G and 5G systems in the first section by giving an overview about the current and future emerging cellular network evolution. The chapter is organized as follows. Section 2 describes briefly the LTE and the LTE-A features. Handover management is then studied in the third section. Finally yet importantly, Section 4 discusses an emerging concept, which is "smart city" in the context of LTE systems. Finally, Section 5 concludes the paper and discusses future work. © 2016 Elsevier Inc. |
