What is 5G? Emerging 5G Mobile Services and Network Requirements

Abstract

Abstract:In this paper, emerging 5G mobile services are investigated and categorized from the perspective of not service providers, but end-users. The development of 5G mobile services is based on an intensive analysis of the global trends in mobile services. Additionally, several indispensable service requirements, essential for realizing service scenarios presented, are described. To illustrate the changes in societies and in daily life in the 5G era, five megatrends, including the explosion of mobile data traffic, the rapid increase in connected devices, everything on the cloud, hyper-realistic media for convergence services and knowledge as a service enabled by big-data analysis, are examined. Based on such trends, we classify the new 5G services into five categories in terms of the end-users' experience as follows: immersive 5G services, intelligent 5G services, omnipresent 5G services, autonomous 5G services and public 5G services. Moreover, several 5G service scenarios in each service category are presented, and essential technical requirements for realizing the aforementioned 5G services are suggested, along with a competitiveness analysis on 5G services/devices/network industries and the current condition of 5G technologies.

Physical Layer Security in a Hybrid TPSR Two-Way Half-Duplex Relaying Network over a Rayleigh Fading Channel: Outage and Intercept Probability Analysis

“…In addition, RF signals can provide both information and energy in communication network nodes, using a well-known technique in the communication cooperative network called a wireless powered network (WPNs). Research in WPNs is therefore an important research direction in both academia and industry [1][2][3][4]. Furthermore, WPNs do not require as much charging, servicing, and maintenance as many battery-powered devices, and this is the great advantage of WPNs in comparison with other types of network.…”

“…All the analytical expressions of the OP and IP of the system model were verified by a Monte Carlo simulation in connection with all the main system parameters. In the research results, the analytical and simulation values were in total agreement, demonstrating the correctness of the system performance analysis.Electronics 2020, 9, 428 2 of 16 solution for future applications of technology such as the Internet of Things (IoT) and the Internet of Everything (IoE) [1][2][3][4][5][6][7][8].Security is increasingly considered a key area for further study on improving wireless communications, especially in the physical layer. Studies on information exchange security have already been extensively performed for the upper layers, but recently, the security of the physical layer has gained significant importance.…”

Hybrid protocol for wireless EH network over weibull fading channel: performance analysis

“…However, energy harvesting (EH) and information transmission (IT) processes from the source (S) node to the destination (D) node in the communication network may be interrupted by fading, shadowing, and path loss. For solving this problem, the intermediate helping relay (R) node between the S node and D node is considered as an excellent solution for enhancing the system performance [1][2][3][4]. There are many types of research focused on the WCPN with helping the intermediate relay with perfect and imperfect channel state information (CSI) as investigated in [5][6][7].…”

Sum Utilization of Spectrum with Spectrum Handoff and Imperfect Sensing in Interweave Multi-Channel Cognitive Radio Networks

“…The scope of 5G services is not limited to personal wireless communications but extends to the services associated with mobile gadgets, wearable devices, sensors, actuators, machines, robots, vehicles, and other applications [2]. 5G technology is expected to be a combination of cooperative heterogeneous networks of multi-tier communication systems and different radio access technologies [3,4].…”
