Survey on backscatter communication for zero-power IoT
Abstract
Although Internet of things (IoT) can enhance the quality of people’s life, but it also brings the problems of energy consumption and network transmission congestion.To solve the above problems, backscatter communication technology for zero-power IoT has been proposed.Thus, it is of great significance to survey the state-of-the-art technologies and study the relevant challenges.Firstly, the basic definition and technical characteristics of zero-power IoT and backscatter communications were presented.Secondly, several typical application scenarios for zero-power backscatter communications in 6G were introduced.Thirdly, the system structure of zero-power backscatter communications was given and the potential key technologies of zero-power backscatter communications for 6G applications were also discussed.Finally, the technical challenges and potential research directions for zero-power backscatter communications were analyzed.Additionally, the proposed overview was of important theoretical significance and practical values for promoting the development of IoT toward full scenes, full spectrum, and many types of services.
