Wide and narrow band channel combined wireless networking method

The invention provides a wireless networking method combining a wide-band channel and a narrow-band channel, which comprises establishing a wireless networking system combining the wide-band channel and the narrow-band channel; wherein the system comprises a narrow-band channel and a wide-band channel, wherein the narrow-band channel is always in a working state and is used for transmitting low-speed data and resource scheduling transmission of the wide-band channel, and the broadband channel is used for transmitting high-speed data and determines whether to work or not according to the service volume and is in a closed state by default. By adopting the method provided by the invention, the average power consumption of the slave node within 1 hour is not more than 200mW (the high-speed data transmission time is not more than 10s), the data rate of a narrowband channel is not less than 5kbps, the data rate of a broadband channel is not less than 12Mbps, and the communication distance is not less than 3km when
