Frequency shifting in low power devices

Abstract

Methods, systems, and devices for wireless communications are described. A radio frequency identification (RFID) tag may receive, from a first wireless device, a continuous wave via a first set of frequency resources and in accordance with a set of transmission parameters. In some examples, the continuous wave may include a continuous waveform for activation of the RFID tag. Based on receiving the continuous waveform for activation, the RFID tag may modulate the continuous wave with data and send, via a second set of frequency resources, a backscattered signal of the continuous wave based on modulating the continuous wave with data, where the second set of frequency resources may be shifted in frequency relative to the first set of frequency resources. In some examples, the backscattered signal may be sent to the first wireless device. In some other examples, the backscattered signal may be sent to a third wireless device.
