摘要： A plurality of masters continuously receives data through a specific channel to detect whether a slave exists nearby. On the other hand, the slave transmits data for a given period through the specific channel by a trigger specified by a user. A master near the slave receives the data transmitted by the slave and recognizes that the slave exists nearby. After the recognition of the slave, the master performs carrier senses on channels other than the specific channel and transmits data for a given period through a channel on which a carrier does not exist. After the transmission through the specific channel, the slave receives a plurality of channels other than the specific channel to receive the data transmitted by the master.
