¿µ¹®³»¿ë¿ä¾à | This standard defines relay network protocol based on MFAN. The relay network
can be created to increase MFAN coverage. MFAN is a wireless network that transmits/receives data using magnetic field from low frequency band. The participating devices in MFAN are divided according to their function into MFAN-C, MFAN-N, and MFAN-R. Only one MFAN-C exists within one MFAN, and several MFAN-N devices form a network centered on MFAN-C. MFAN-R creates another network including MFAN-Ns which are not involved in the MFAN created by MFAN-C due to the communication range. MFAN-C manages the connection and release of MFAN-N and MFAN-R. MFAN is based on TDMA(Time Division Multiple Access). MFAN-C manages MFAN, and when MFAN-N and MFAN-R are connected to the MFAN, MFAN-C allocates the wireless resource(time). MFAN-R communicates with MFAN-Ns in the relay network coverage based on the allocated wireless resource from MFAN-C |
