Backscatter Communication

Most wireless IoT does not require a high data rate but it consumes a lot of energy.

Because supplying power is difficult job, Bluetooth or Wi-Fi is excessive specification for IoT devices.

  • Reuse the signal resources of existing Wi-Fi infrastructure.
  • Save energy more than 10,000 times by modulating backscattered signal of the existing ambient signal at the tag side.
  • Guarantee communication distance of several tens of meters and a transmission speed in Mbps.

for when many heterogeneous devices communicate at the same time in Wi-Fi backscatter.
