In the era of Society 5.0 or Industry 4.0, wireless Internet of Things (IoT) becomes a key technology for the realization of smart factory. To increase the efficiency of frequency usage, we have proposed 5GHz Wi-Fi communication with simplified beam forming system in which Wi-Fi backscatter communication system is introduced to detect the information of sensor nodes (SNs). We reported the Access Point (AP) can detect the clock signal of SN by mixing the received backscatter signal with transmitted Wi-Fi signal in our experiment. In this paper, we analytically describe the operation of AP’s receiver in this system and confirm this operation by MATLAB simulation. The transmit Wi-Fi signal differences between single-carrier and multi-carrier modulations (with/without guard interval) are discussed. |
