DEVICES AND METHODS FOR BACKSCATTER COMMUNICATION USING ONE OR MORE WIRELESS COMMUNICATION PROTOCOLS INCLUDING BLUETOOTH LOW ENERGY EXAMPLES

摘要

Examples described herein include devices and methods that may facilitate interoperability between backscatter devices and wireless communication devices. For example, backscatter devices and methods for backscattering are described that provide a transmitted backscattered signal formatted in accordance with a wireless communication protocol (e.g. Bluetooth Low Energy, WiFi, IEEE 802.11, or IEEE 802.15.4). Such communication may reduce or eliminate any modifications required to wireless communication devices necessary to receive and decode backscattered signals.

1. A device comprising:
an antenna configured to receive an incident signal having a carrier frequency; a modulator; and a symbol generator, wherein the symbol generator is configured to provide a subcarrier frequency, and wherein the symbol generator is further configured to control the modulator to backscatter the incident signal having the carrier frequency using the subcarrier frequency to provide a backscattered signal to the antenna, the backscattered signal including a bandpass signal in a predetermined frequency range.
