LOCAL WIRELESS COMMUNICATION SYSTEM AND METHOD FOR ADAPTIVE CHANNEL SELECTION OF SENSOR SYSTEMS

摘要

An apparatus for performing a local wireless communication using a frequency band. At least a part of the frequency band is divided into a plurality of channels. The apparatus includes a plurality of sensors, each sensor scanning each channel to identify whether each channel is used or not, selecting an unused channel as a data transmission channel, and transmitting data through the unused data transmission channel. The apparatus further includes at least one hub receiving and processing the data transmitted from each sensor through each corresponding data transmission channel.
