Research of Sixth Generation (Sixth Generation (6G)) has been started in late 2019 to early 2020 in various sectors like academics, industries, and all. It is expected to be developed and released by the early 2030s by following a pattern of new-generation wireless technological network development every decade with innovative capabilities and improved connectivity. This research paper focused on some in-depth analysis of what 6G network requires and the challenges depend on various aspects with some suggestive solutions upon them. The paper also holds some future directions on satellite networks, terahertz technology, AI powered intelligent surface, emerging technologies, edge computing and AI-driven network optimization, artificial intelligence, blockchain etc. The paper highlights key performances for 6G network in comparison to Fifth Generation (5G) network where the development of network with digital twins to work as a sensor capability to increase the intelligence power of network as well as the capabilities of sensing.
