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.
