无线射频反向散射的现状、问题及发展趋势OA

Wireless radio frequency backscatter is characterized by shared spectrum,low power consumption,and low cost,and it has important application value in the terminal devices and repeater markets of communication and sensing.Mobile communication technology has always been a hotspot of development.The transition from 5G to 6G is not only about speed but also about evolving from the Internet of things to the Internet of intelligent things.Both mobile communi-cation technology and Internet of things technology face the problem of spectrum scarcity,there is also demand for low-power energy-saving design,creating intersections with wireless radio frequency backscatter communication.Firstly,by exploring research hotspots such as mobile communication and Internet of things technologies,the wireless radio fre-quency backscatter communication was introduced in this study.Secondly,through reviewing seminal papers on the envi-ronmental backscatter communication,recent research,and fundamental principles,a clear developmental trajectory was mapped out and the current state was categorized across different dimensions.Then,based on this developmental trajectory and classification,existing issues and partial solutions were identified.Finally,combining the analysis of the full text,the next phase of development trends were predicted in this study.
