PROBLEM TO BE SOLVED: To provide a magnetic field communication method for low-power node management which improves the communication performance and efficiency of a radio network of a magnetic field communication low-requency band.SOLUTION: Though the magnetic field communication method for low-power node management is performed in a radio network of a low-frequency band that is comprised of one MFAN-C and at least one MFAN-N, a physical layer frame is comprised of a preamble, a header, and a payload, and the preamble is comprised of a wake-up bit string and a synchronization bit string. The wake-up bit string is desirably added to only the preamble of the frame that is transmitted from the MFAN-C when the MFAN-N is activated from a power saving mode. The wake-up bit string is desirably modulated using an ASK system, and the synchronization bit string is desirably modulated using a BPSK system. |
