Problems solved by technology
Existing wireless communication devices require large power consumption at both the sending end and the receiving end
Even electronic tags in radio frequency technology need a specific reader to send a signal as a driver, which cannot be achieved without additional equipment and energy consumption support
Due to the rapid development of technologies such as the current sensor network, if the existing communication technology is used, how to provide continuous and effective power to the sensors or objects everywhere becomes very important, and there is no proper solution for this.

The invention discloses wireless communication equipment. The wireless communication equipment comprises a signal transmitting device for modulating a target signal into an existing wireless signal in a communication media to form a modulation signal, and transmitting the modulation signal, and a signal receiving device for receiving the modulation signal, filtering the modulation signal and demodulating the filtered modulation signal to obtain the target signal. The invention further provides a corresponding communication method of the wireless communication equipment. In the wireless communication equipment provided by the invention, energy needed in the reception and transmission of signals can be completely supplied by electric energy generated by existing radio signals in the communication media, so that wireless communication requiring no additional electric energy support is realized, and wireless communication of ultralow energy consumption is realized.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless communication device and a wireless communication method. Background technique [0002] Wireless communication is a communication method that uses the characteristics that electromagnetic wave signals can propagate in free space for information exchange. The communication equipment modulates the signal into a specific electromagnetic wave, and then transmits it through the antenna through power amplification, and the receiving equipment receives the signal through the antenna, then detects the original signal and restores the signal. [0003] At present, the existing wireless communication equipment mainly transmits information by modulating the information to be transmitted into a high-frequency electrical signal, and then converting the electrical signal into a specific electromagnetic wave; at the receiving end of the electromagnetic wave, the...
