Review of the Security Risks and Practical Concerns with Current and Future (6G) Communications Technology

Gradually, the 6th Generation cellular network standard is being adopted (6G). Due to the creative and distinctive features of 6G, such as the capacity to deliver connection even in space and underwater, governments, corporations, and academics are investing a substantial amount of time, money, and effort in this subject. The next generation technology will be effective around the year 2030–2035. The next generation will be able to provide strong connectivity between machines and mobile devices. The speed can reach 1 Gbps in the downlink and 500 Mbps in the uplink. Edge computing, blockchain, advanced IoT and Li-Fi (Light Fidelity) technologies, as well as Artificial Intelligence (AI), are believed to provide the foundation for forthcoming innovations. Further research into the fundamental architecture of 6G is necessary to pinpoint these areas for development. We have examined a variety of concerns that might arise while employing next generation communication technologies, such as security and practical concerns. All of the physical layer's facts, which are crucial for implementation, were taken into account during the study. The conclusion of the study includes all the pertinent information and arguments that researchers might take into account while they work on next generation communication technologies.
