HitchHike: Practical Backscatter Using Commodity WiFi (2016, methodology): “Further, recent work such as Passive WiFi also requires twice the spectrum compared to other approaches such as BackFi, since they generate the RF excitation tone signal on the center of two WiFi channels and the backscatter tag frequency shifts and reﬂects the excitation signal on both the two…”
Inter-Technology Backscatter: Towards Internet Connectivity for Implanted Devices (2016, background): “While recent work on passive Wi-Fi [28] signiﬁcantly reduces the power consumption of Wi-Fi transmissions using backscatter com-Figure munication, it requires infrastructure support in the form of specialized hardware that can generate the continuous wave RF signal needed for backscattering Wi-Fi…”

Cooperative Ambient Backscatter Communications for Green Internet-of-Things (2018, background): “A passive WiFi system is proposed in [8] which requires a dedicated device to transmit RF sinusoidal carrier at a frequency that lies outside the desired WiFi channel, such that the WiFi receiver can suppress the resulting out-of-band (direct-link) carrier interference.”
Modulation in the Air: Backscatter Communication Over Ambient OFDM Carrier (2017, methodology): “A passive WiFi system is proposed in [13], which requires a dedicated device to transmit RF sinusoidal carrier at a frequency that lies outside the desired WiFi channel, such that the WiFi receiver can suppress the resulting out-of-band (direct-link) carrier interference.”
