Abstract

As one of the core enabling technologies supporting the batteryless Internet of things(IoT)

ambient backscattering communication technology has the characteristics of low power consumption and low cost.Firstly

the basic concept of ambient backscattering communication technology and the research status at home and abroad were introduced.Then

based on an in-depth analysis of the differences between ambient backscattering communication technology and RFID technology

the technical difficulties faced by the ambient backscattering communication system were described in detail

including large detection delay

high bit error rate

low transmission rate and short communication distance.In addition

a series of potential solutions to the challenges were proposed.Finally

the future research directions of ambient backscattering communication were prospected.
