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.

Local wireless communication system and method employing frequency-variable signal detection

An antenna is located at the end of a wireless communication system, or other radio system, and more particularly, a wideband planar antenna with linear and circular polarization uses different polarization for transmission or reception to increase the isolation between the transmission and reception by suggestion and using a type of radiation element. The disclosed antenna is more efficient than other similar antennas that can transmit/receive linear or circular polarization. The disclosed invention makes it possible to pr vide an antenna having dual polarization, which has an orthogonal characteristic in both linear and circular polarization, and which can lower the height of the antenna by embodying a micro strip planar antenna which has linear and circular polarization that has high gain over a wide frequency band, and which transmits/receives linear or circular polarization.
