6G Wireless Communication Networks: Challenges and Potential Solution

Introduction

The fifth-generation networks (5G) are under construction commercially soon launched in most countries worldwide. It is predicted that 4G may arrive at the bottleneck before 2020, and 5G might be 2030. However, the upcoming wireless network system is being evolved based on recent advances in wireless and networking systems such as software-defined networking and virtualization in 5G and Artificial Intelligence (AI), Internet of Thing (IoT), Internet of Everything (IoE) and Virtual Reality need high reliability, low latency and ultra-high-speed for the uploading and downloading in 6G(Ahmad & Afzal, 2020)(Almrezeq et al., 2022). 5G has higher bit rates with more than 10 gigabits per second than previous technologies, more capacity, and low latency. This is a strong point for the one thousand million attached devices regarding the Internet of Things. Moreover, there are exceptional services available in the age of 5G like blockchain-based facilities, Unmanned Aerial Vehicle (UAV), data networking, fog computing, vehicle–to–vehicle communication, smart grid and smart parking etc. The up-gradation work of 5G networks has been finished and is now ready for deployment worldwide with its full features for commercialization.

The significant drawbacks of 5G wireless communication are less able to deliver a fully cybernetic and expert system that provides all kinds of service with an altogether fascinating experience (Nawaz et al., 2019). Even though the 5G mobile technology will be started coming week with new facilities over the established systems, but cannot resist completing the needs of the next-generation system after ten years (Md. Alimul Haque, Anil Kumar Sinha, 2017). The 5G technology will provide significant advancement and give high quality of service (QoS) compared to previous technologies (Shafi et al., 2017). However, the rapid development of automatic and data-centric systems can transcend 5G wireless communication’s properties. Some technologies, like the virtual reality (VR) system, needed to go beyond 5G (B5G) because it requires a minimum rate of 10 Gbps data rate (Mumtaz et al., 2017). So, in 2030 5G has no scope to sustain itself in the technology sector due to limitations. Drawbacks and limitations of 5G and the emerging revolutionary technologies drive the development of next-generation called 6G networks (Zong et al., 2019).

To overcome constraints of 5G, the transition from radio to sub terahertz (sub-THz) and optical spectra supporting explosive 6G applications with new features that are attractive(Whig et al., 2022). The significant attributes of 6G will be the convergence of all the prior attributes, such as excellent connectivity and reliability, low power intake, network densification and higher throughput using security. Even the 6G wireless network would likewise continue the rate of these past generations, which contained services, which included new services with new technologies. Sensible wearables devices, Artificial Intelligence, autonomous automobiles, computing reality devices, enhancements, sensor and 3D mapping (Elsayed & Erol-Kantarci, 2019) will undoubtedly be popular and new services in 6G. Managing a huge volume of data and fast connectivity of each device would be the primary and vital challenges in 6G wireless networks. Even though the 5G arrange time has not yet wholly shown up, the obstacles of 5G innovation mean we should start researching the 6G network now.

Be that as it may, what is a 6G network? Also, by what method will it be different from 5G systems? Up until now, the 6G network has no standard capacities or particulars, just numerous prospects. A few expert users fight that 6G systems should be something other than a quicker form of a 5G technology; actually, the advancement in 5G connectivity in different ways. For instance, inclusion will not be constrained to the bottom level, like the 5G system. Instead, it would have complete undersea surface region inclusion.
