An RF(Radio Frequency) communication method using channel hopping is provided to conduct communication by automatically changing a communication channel during low-speed RF communication, so as to increase the communication output, thus channel interference is minimized and a communicable range is extended. Plural channels are employed. The first communication device and the second communication device where at least one of the plural channels is set to fundamental channels accord the fundamental channels for mutual communication according to a communication initiate signal, and carry out the first communication by using the accorded fundamental channels. During consecutive communication, the first and second communication devices perform the second communication as moving on the plural channels. |
