¿µ¹®³»¿ë¿ä¾à This standard defines method of two-way long distance wireless communication protocol for RF wireless power transmission by using backscatter modulation of ISM band frequency signals between STA(Station) and SSN(Smart Sensor Node, including IoT, sensors, tags, wearable devices) device. There are three required components for two-way long distance wireless communication protocol by using backscatter modulation of ISM band signals. First one is a STA device which transmit the wireless power and data packets to SSN device by forming a ISM bnad signal channel between HIE AP. And second one is a batteryless SSN device which change the signal level sensitivity by channel backscatter modulation after received signal from STA device. And last one is a HIE AP device which decode the received changed channel level from ISM band signal backscatter modulation of SSN into digital signal 0 or 1. And this standard defines a back scattering parasitic communication protocol among the three components with applying the CSI(Channel State Information) or RSSI(Received Siganl Strength Indication) detection method of ISM bnad communication. And this proposed standard provides a communication protocol for RF wireless power transmission with a maximum dozens of kbps data rate under the below 1m distance in theory.
