Abstract

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 require low complexity and inexpensive structure. And OFDM method is considered for system performance. Further, when the high throughput and various traffic characteristics of the system are required, it can be considered that the method of IEEE 802.11 OFDM PHY mode is used.

본 논문은 다양한 통신 방식이 사용될 수 있는 M2M 환경에서 동일한 주파수 대역을 사용하는 통신 방식인 IEEE 802.15.4g와 IEEE 802.11 방식의 각 PHY Mode를 AWGN 채널 하에서 시뮬레이션을 통해 BER과 FER 성능을 비교한다. 이를 통하여 요구되는 파라미터에 적합한 통신 방식에 대해 고찰한다. IEEE802.15.4g의 경우, 구현의 복잡도와 낮은 가격을 위하여 FSK를 사용하고, 높은 성능이 요구될 경우 OFDM 방식을 사용하는 것이 적절하다. IEEE 802.11의 경우, 시스템의 트래픽 특성이 다양하고 높은 전송률이 요구될 때, 트래픽 특성에 맞는 OFDM PHY mode를 사용하는 것이 적절하다.
