Terahertz Communication: Merits, Demerits, and Future Challenges Regarding 6G Wireless Networks

Abstract

In today’s era, the Internet is, like food and shelter, a basic necessity of human beings. And in a survey, it has been told that by 2030, the world’s population will reach 8.5 billion. Which is 20% more today compared to 2020 which is 7.8 billion to provide internet for everyone. It has become very important to work on the Channel spectrum. Nowadays, there are very few people who are unaware of the world of the Internet. Most of the people are connected to social media, due to which cybercrime is also increasing and it has become very common to all. So, this paper has been written to reduce cybercrime. And the second thing is that by 2030, the world will be governed by the Internet of Things (IoT). And IoT is aware that those who are its devices need a drastic speed of the Internet. This is the reason why the new generation began 6G, in which Terahertz Communication technology has a very important role where high frequency is used, but working on high frequency will also increase our health issues, which has also been talked about in this paper. Furthermore, in this paper using Terahertz Communication has been explained for 6G and how our system will be safe from using Terahertz Frequency so that no one else can access and control the system.
