Comparison of heterogeneous communication systems for M2M environment

This paper presents BER, FER performance comparison, especially on PHY mode of IEEE 802.15.4g and IEEE 802.11 under AWGN channel through a simulation, which is communication method using identical frequency bandwidth in M2M environment. This considers suitable communication method of required parameter. It is advantageous that FSK method is used in situations where the system requires low complexity and inexpensive structure. When the high throughput and various traffic characteristics of the system are required, the method of IEEE 802.11 OFDM PHY mode can be considered.
