在物聯網中，有許多的智慧物件採用ZigBee通訊協定來達到低耗能通訊的目的。然而，物聯網中的ZigBee網路通訊範圍有限，所以在一些坪數較大環境中，例如：工廠、樓中樓、公司、別墅等，若僅使用一台WiFi AP，則眾多以Zigbee為傳輸標準之物聯網設備，會因為ZigBee傳輸多跳、訊號強度較弱、容易受到干擾、穿透性較弱等缺點，而導致傳輸效能低落，甚至發生有些地方完全無法連線的情況，而相較於物聯網中的Wi-Fi網路訊號，其傳輸範圍廣、訊號強度較強、訊號具穿透性等優點。基於此，本論文擬研發一「具監控機能之多功能IoT基地台」，使其不但能夠延伸物聯網基地台的Wi-Fi訊號，亦能局部連結環境中的ZigBee裝置，將其資料透過Wi-Fi轉送至物聯網基地台，進而提升網路傳輸品質。本論文所研發訊號加強器亦嵌入Camera模組，使其兼具監控能力，並將其監控畫面利用其Wi-Fi傳遞至物聯網基地台，以符合物聯網環境中隨處需要監控的需求。

In internet of things (IoTs), an amount of smart objects based on ZigBee standard are used for achieving the goal of the low power consumption in communication. However, the small communication range of ZigBee devise cannot fully cover the widely region, including factory, mezzanine floor, villa, office, and so on. Therefore, the problems of limit communication range, multi-hop transmission, low signal strength, and interference result in low network performance even if each device cannot communicate with each other. Compared with ZigBee standard, Wi-Fi standard has larger communication range and better signal strength than that of ZigBee standard. Based on the above-mentioned features of Wi-Fi standard, this thesis propose an “Access Point Repeater with Monitoring Functionality” in weak-signal and multi-hop ZigBee environment. As a result, the proposed repeater not only extend the base station signal of Wi-Fi but also connect the nearby ZigBee device in local environment. Overall, the packets via Wi-Fi base station can forward to the proposed repeater and thus enhance the quality of packet transmission. In addition, the repeater is also embedded camera module to monitor the given region. Then, the snapshot of the monitoring area can be transmitted to Android smartphone by Wi-Fi standard. Consequently, the requirement in monitoring functionality for IoTs can be achieved.
