A Review Of 5G Technology: Architecture, Security and wide Applications

The eventual goal of the forthcoming 5G wireless networking is to have relatively fast data speeds, incredibly low latency, substantial rises in base station’s efficiency and major changes in expected Quality of Service (QoS) for customers relative to the existing 4G LTE networks. In order to deal with state-of-the art technologies and connectivity in the form of smart cell phones, internet of things (IoT) devices, autonomous vehicles, virtual reality devices and smart homes connectivity, the broadband data use has risen at a fast rate. Further, to meet the latest applications, the bandwidth of the system needs to be increased widely. This development will be accomplished by using a modern spectrum with higher data levels. In particular, the fifth generation (5G) mobile network seeks to resolve the shortcomings of previous telecommunication technologies and to be a possible primary enabler for future IoT applications. This paper briefly discusses the architecture of 5G, following by the security associated with the 5G network, 5G as an energy efficient network, various types of efficient antennas developed for 5G and state-of-the-art specifications for IoT applications along with their related communication technologies. We have also outlined the broader usage of 5G and its future impacts on our lives. Furthermore, at the end of each subtopic, the necessary recommendations are given for the future work.即将到来的第五代（5G）无线通信网络的最终目标，相较于现有第四代长期演进（4G LTE）网络，旨在实现相对更快的数据传输速率、极低的延迟、基站效率的大幅提升，以及客户所期望的服务质量（Quality of Service, QoS）的重大变革。为适配智能手机、物联网（Internet of Things, IoT）设备、自动驾驶汽车、虚拟现实设备及智能家居连接等前沿技术与连接场景，宽带数据使用量正以迅猛速度增长。此外，为满足新兴应用需求，系统带宽亟需大幅扩容。上述发展将通过采用具备更高数据承载能力的新型频谱来实现。具体而言，第五代（5G）移动通信网络旨在弥补前代通信技术的短板，并成为未来物联网应用的核心赋能技术之一。本文简要探讨了5G网络架构，随后介绍了5G网络相关的安全问题、作为节能网络的5G技术、专为5G研发的各类高效天线，以及面向物联网应用的前沿技术规范与相关通信技术。本文还概述了5G的广泛应用场景及其对未来人类生活的影响。此外，每个子主题的末尾均给出了未来研究方向的相关建议。
