As wireless communication continues to evolve, the next generation 7G wireless communication promises to deliver even faster data speeds, lower latency, and higher capacity than 5G and 6G. The development of 7G networks is expected to leverage advancements in terahertz waves, massive MIMO, and artificial intelligence to provide an even more seamless and efficient wireless communication experience. This paper provides an overview of the current state of research on 7G wireless communication technology including potential areas, benefits and challenges. Furthermore, we explore the possible applications of 7G technology in various industries, such as healthcare, transportation, and entertainment. Finally, this paper discusses the potential societal and environmental impact of 7G technology, as well as the regulatory and ethical considerations that must be addressed in its development.
