BACKSCATTER-BASED REMOTE CONTROL DEVICE AND ENVIRONMENTAL INFORMATION ACQUISITION DEVICE

摘要

The present application relates to a backscatter-based remote control device and an electronic device having a remote control function. The backscatter-based remote control device comprises an antenna, a receiver, and a backscatter transmitter; the antenna is used for receiving a radio frequency signal, transmitting the radio frequency signal, and transmitting a backscatter signal; the receiver is used for receiving, by means of the antenna, a carrier CW signal transmitted by an electronic device; and the backscatter transmitter is used for transmitting the backscatter signal to the electronic device on the basis of the CW signal and by means of the antenna, the backscatter signal comprising control information for the electronic device. Embodiments of the present application can provide a remote control device which does not need a power supply.
