1G, the first generation of wireless cellular technology was born and by 1984. In Path to 5G, 1G facilitated the introduction of the mobile phone to consumers. 2G was created on a digital cellular network standard. 3G standards were required to provide peak data rates of at least 144 Kbps with a maximum of 14 Mbps. 4G offered faster web access and added cloud, gaming, High Definition (HD) videos, and 3D TV to the growing list of amenities devices that it could handle. The 5G technology standard for broadband cellular networks to provide connectivity for cell phones began deploying worldwide in 2019. 6G (Sixth Generation Wireless) the successor to 5G cellular technology, will be able to use higher frequencies than 5G networks and provide substantially higher capacity and much lower latency. One of the goals of the 6G internet is to support one microsecond latency communications. Examples of 6G include e-health for all, precision health care, smart agriculture, earth monitor, digital twins, cobots and robot navigation. 6G networks will operate by using signals at the higher end of the radio spectrum. Primarily, 6G will operate by Making use of free spectrum, Improving the efficiency of the free spectrum, taking advantage of mesh networking, Integrating with the “new IP. Network Security is the security designed to protect the integrity of the network from unauthorized access and threats. Network Security is one of the most important aspects to consider when working over the internet, no matter how small or big your business is. The network Security consists of Protection, Detection, and Reaction. Data Privacy generally means the ability of a person to determine for themselves when, how, and to what extent personal information about them is shared with or communicated to others. Impacts in 6G include Advancing Extended Reality, Artificial Intelligence, Machine Learning, Digital Twinning, and more, 6G Shows Potential to Optimize Communications, Interoperability, and Sustainability. The development of the 6 G network faces many challenges: the technological issues include terahertz waves, peak throughput, higher energy efficiency, connection flexibility, and self-aggregating communications fabric; the non-technical challenges include industry barriers, spectrum allocation and usage rules, and policies and regulations. Security Issues in 6G are Virtualization Security Solution, Automated Management System, Data security using AI, Users’ Privacy-preserving, Post-Quantum Cryptography. Impacts and Challenges of Network Security and Data Privacy in 6G Environment include real-time intelligent edge, distributed AI, intelligent radio, and 3D intercoms. The main security and privacy concerns here relate to authentication, access control, data transmission and encryption.
