本篇論文探討低功耗關鍵性基礎建設監控(LECIM)技術之相關議題。首先針對LECIM的緣起、LECIM的應用需求、及制訂中的LECIM相關標準進行簡介，並對LECIM未來可能的發展走向作一闡
述。其次針對LECIM及WSN系統，應用於公共建設、大樓、橋樑等進行監控的論文，作應用案例
探討。最後針對一實際案例大樓跨住戶的無線感測網路(Wireless Sensor Network；WSN)應用之無線訊號傳輸及通訊模組耗電進行探討，期能將此實例的經驗，對於未來LECIM系統的規格制訂及技術發展，提供一個借鏡。

This article introduces the Low Energy Critical Infrastructure Monitoring and its deployment issues. First, we describe the initiation and requirements of LECIM. Then, we overview the on-going LECIM standardization, and do a prediction on it. LECIM and WSN system can be deployed for monitoring the public infrastructure, buildings and bridges, we provide a brief paper study on this area. Finally, a practical case of Wireless Sensor Network(WSN) Application is presented. In this case, a study for the wireless signal transmission and power consumption of wireless modules in building environments is followed. We wish this real case can be a good reference for further standardization of LECIM.
