초록

본 논문에서는 다중통신용 다중 대역 M2M 게이트웨이 등에 활용할 수 있는 지그비 센서 노드를 구현하였다. 센서 노드용 무선 네트워크 주파수 대역 및 표준은 IEEE 802.15.4-2003로서 지그비 주파수이며 통신기능을 수행할 송 수신소자로서 Ember사의 SoC Type EM357을 사용하였다. M2M 게이트웨이 본체와 센서 노드에 동일 소자를 사용하였으며 운용 프로토콜은 Ember사가 제공하는 EmberZNet Stack 4.5.4을 사용하여 구현하였다. M2M 게이트웨이에 지그비 센서를 장착하여 패킷을 전송시켜 수신모듈의 특성을 측정하였다. 지그비 주파수의 수신감도인 -98 dBm에서 패킷 오류율이 0%임을 나타였으며, 또한 저전력회로 구현으로 지그비 모듈은 우수한 전류특성을 보였다.

This paper describes the implementation of a ZigBee sensor node that can be utilized as a multiband and machine to machine (M2M) communication gateway. The IEEE 802.15.4-2003 standard was used as the wireless network frequency band. Ember's Type EM357 SoC was used as the transmission and reception device to perform the communication function, and it was also used for both the main M2M gateway and the sensor node. For the implementation of the operating protocol, EmberZNet Stack 4.5.4 from the Ember Corporation was used. The measurement of the reception sensitivity in the receiving module and the actual output signal from the reference were obtained from the transmission of a packet, and the packet included the M2M gateway within the attached ZigBee sensor. The packet error rate was measured as 0% with a -98 dBm reception sensitivity at the ZigBee frequency. In addition, excellent current characteristics of the ZigBee modules were shown by the implementation of the low-power circuit.
