Abstract

The invention discloses a system for sensing a motion and executing wireless communication, comprising one or more antennas, one or more electric switches, a motion sensing receiver, a transceiver and one or more processors, wherein one or more antennas are used for transmitting and receiving wireless data communication signals and motion detection electromagnetic waves; the one or more electric switches are switched among electric pathways for activating channel scanning, motion sensing, interference detecting and data communicating; the motion sensing receiver is used for receiving the motion detection electromagnetic waves; the transceiver generates modulated RF (Radio Frequency) signals for wireless communication and unmodulated RF signals for motion detection, wherein the unmodulated RF signals bypass a transceiver modulator; and the one or more processors are used for processing motion detection electromagnetic wave data and detected interference signal data, transmitting wireless communication data to the transceiver and processing the wireless communication data from the transceiver, controlling the one or more electric switches and providing commands for the transceiver.

Description

technical field [0001] The invention relates to a wireless data communication system and a system utilizing electromagnetic wave motion sensing. More specifically, the present invention relates to a circuit system that performs the dual functions of wireless data communication and motion sensing in a sequentially timed manner. Background technique [0002] Traditionally, wireless communication devices (eg, a WiFi network access point or adapter in a WiFi network or a portable phone in a cellular communication network) are used only for data or voice communication. Motion detection systems are often implemented individually as stand-alone devices, such as burglar alarm systems and speed radars. [0003] One motion detection technique is based on the Doppler effect. The Doppler effect is the change in wave frequency of an observer moving relative to / away from the wave source. The frequency of the sensed waves is higher when the observer moves closer to the wave source, but ...
