WebFully passive wireless networks are an enable for the internet of things. One of the hypothesis for this passive network implementation is to use backscatter radio nodes. Nevertheless, the traditional approach is to use ASK or PSK backscatter solutions that limits the data rate of the sensors, since it transfers only one bit per symbol period.
