由於無線通訊技術之成熟與相關產品價格之降低，無線區域網路之架設已漸普遍，存取點位置的選擇，對於整體無線區域網路的通訊品質亦較以往將更具影響力。因此本論文即利用個人數位助理（Personal Digital Assistant；PDA）之高度可攜性，配合所研製之軟體，以輔助業界於建構無線區域網路時，進行存取點位置之設定。在本論文中針對業界實際需求，可於PDA上初步繪製架設環境中的位置關係圖，隨後進行存取點與網路配置架構之通訊品質量測，以供工程人員維運及管理之用。另著眼於目前臺灣行動通訊之建設已日臻完備，內建J2ME（Java 2 Micro Edition）的手機必將漸為市場主流，因此本論文亦提出移動式資訊裝置家電系統之控制架構，開發一符合Java語言中之J2ME規格的儀電資訊描述語言，並將其嵌入至電力設備網路中，可有效輔助電力操作人員施行廠區設備之監控，暨有助於電力系統運轉安全之提昇。

Following the advent of wireless technology along with the cost reduction of communication devices, the wireless network is seen more popular than ever, hence increasing the importance of the access points for the layout of the communication structure. In other words, as the wireless networks are extended broadly, the layout quality of access points will be crucial to the overall communication performance. Thanks to the emergence of personal digital assistant (PDA), this device is therefore employed as the aid for the layout of access point in wireless networks for this study. Aimed at meeting the requirements of communication practitioners, the layout map can be sketched in the personal digital assistant via the proposed software. In this way, the engineers can grasp the relationships among access points and wireless-connected devices in anticipating of ensuring a high communication performance. Besides, in view of the well-constructed mobile communications of Taiwan where the Java cell phone will become dominant in the near future, an instrument information meta language (I2ML) developed based on the J2ME specifications is also proposed in this thesis. This proposed software could be embedded within the electric power equipment such that the control and operation of a power system can be better realized. Meanwhile, the supervision quality of industry plant is also significantly improved, enhancing the reliability and security of power system operations.
