摘要
6G represents the next generation of mobile communication and mobile networking.Following the previous five generations of mobile communication systems(from 1G to 5G),the development of the 6G mobile communication will be a revolution.As a holographic and ubiquitous multidimensional network,6G will present us with the ability to establish full coverage of the“air–space–sea–land”system and to integrate with AI,IoT,and blockchain to form a network ecosystem.Our study addresses and emphasizes the literature that focuses on the technological perspectives of 6G,most specifically,its technological characteristics,key enabling technologies,and potential applications.In addition,a thorough description of the development of the mobile communication system from 1G to 6G is illustrated.This paper plays the important role of introducing a technological view of 6G to practitioners and researchers.
