# Future Generation 5G Wireless Networks for Smart Grid: A Comprehensive Review
This provides the required system analysis with the needed reliable communication systems, which is an important building block of smart grid visibility. According to the communication standards, different communication technologies [11; 12] can be classified based on either wired and wireless communications. Presently, wireless communications are preferred over wired communications for various reasons and in distinct applications with the reliability of cost at lower rates. This enhances infrastructure and provides readily available connections, even in remote areas. There are diverse factors, such as operational costs, environmental concerns, and availability of resources, to consider when choosing a proper, stable communication system. The voluminous and steady growth of communication technology over past decades is clearly explained in Figure 1. The development of new communication infrastructure with the existing wireless technologies can be more advantageous in smart grids. This provides advanced infrastructure where the need to spend additional cost and time [13] can be avoided. This establishes up-gradation of new wireless communication technologies for future smart grid communication systems [14; 15; 16; 17; 18; 19]. For the past four decades--and marching towards the new wave of the technological era--growth of communication technologies has been an inevitable part of all modes of applications. To address prominent issues for developing new generation cellular communications, certain parameters must be addressed. These include capacity data rate increase with reduced latency and subsequent service quality. In accordance with the report by Navigant research [20], fifth generation (5G) communication networks are found to be more multi-functional and also very flexible. This provides a greater platform to support many critical issues and also solves many problems with respect to cost analysis and power applications. The 5G networks are expected to establish a greater scale upon which to pivot to the fourth industrial revolution. It provides a convergence of pervasive broadband, sensing, and intelligence, which causes greater change in society and industrial markets. Moving into new wireless communication networks can bring the Internet of Things (IoT) into future power markets, providing greater benefits to the utilities and the consumers. Historically, among the public networking

Bringing in 5G networks in a smart grid can establish new business models at the utility side with edge and fog computing along with automation and intelligent control [21; 22; 23; 24]. The 5G technology relies on smaller cell functions for its slicing network, which provide different assets at the distribution and the transmission sides to work on in a ubiquitous manner. This work describes the need for 5G technology in a smart grid and the areas where the new power grid can benefit the access of data. The main aim of this work is to demonstrate 5G architecture in general compared to other wireless technologies and new networks in a smart grid, thus bringing the Internet of energy into the future. Section 2 depicts the overview of wireless communication technologies and the growth of new 5G networks with comparisons. Section 3 shows the complete understanding of 5G architectures and the domains needed. Section 4 gives an overview map of 5G and smart grid road maps, exhibiting the design, the architecture, the challenges, and the future applications. Section 5 shows the future roadmap and the concluding remarks of this new analysis.
