  Abstract

mMTC (massive machine type communication) is an important research topic since it is one of the 3 pillar service categories of in 5G (5th Generation) and it can be extended into wireless sensor network system. Recently, an ambient backscatter communication system has attracted very high attention as realization technology of mMTC services. Ambient backscatter is a communication system that uses an ambient RF signal and has the characteristic of very low power consumption. These features are greatly important to realize mMTC. However, communication performance is limited because the ambient RF signal is used. In this paper, link budget analysis is investigated considering the interference signal generated in the ambient backscatter environment. In addition, an analysis method is presented that newly adds a loss term generated in ambient backscatter. As a result of analysis, it is found that the maximum communication distance of ambient backscatter is considerably limited. So, additional margin or more power assignment should be considered to design the real implementation system.
