Estimating the term…
A system for performing a local wireless communication using a predetermined frequency band divided into a plurality of channels. The system includes a hub for scanning each channel to identify available one of the plurality of channels and transmitting data over the available channel. The system further includes a sensor set to start to operate when the sensor detects a signal within the predetermined frequency band. The sensor spectrum-senses the signal of the frequency band for each channel, and analyzes a header of packet data for each channel, and receives and processes the packet data if the signal is identified to have a designated code.
A system for performing a local wireless communication using a predetermined frequency band, the system employing frequency-variable signal detection, wherein at least a part of the predetermined frequency band is divided into a plurality of channels, the system comprising:
A local wireless communication method employing frequency-variable signal detection, in which at least one hub performs local wireless communications with a plurality of sensors at a predetermined frequency band, the method comprising:
