6G, LIFI and WIFI Wireless Systems: Challenges, Development and Prospects

Abstract

While 5G is being deployed commercially worldwide, scientists have carried out research for 6G as well as WIFI 6G bands, and LIFI are also tested. Both advantages and disadvantages of these three wireless communication methods are focused and the respective application scenarios are described as well as the difficulties and challenges to be overcome. An integrated network system of space and earth is proposed to provide users with ubiquitous wireless network connection. Technologies and challenges required by three communication methods are sorted out and the way they can be combined and applied are analyzed through extensive research and analysis.
