摘要

無線傳感器網路快速發展，開啟了物聯網，生活水平也跟著提高，智慧家庭、智能學習、運輸、遠程監控等，物聯網而設立高度的隱私性、完整的覆蓋範圍、可靠性、低延遲，這些都是通往物聯網重視的課題。
目前行動物聯網以LPWAN為主，具有長距離、省電特性，技術分別有NB-IoT、LoRa及Sigfox，三種技術各有長短，因此可以互相共存，未來新技術的發展，將取決這三個技術的截長補短。
物聯網技術，感測技術、網路通訊技術、雲端服務技術，使產品不再是透過使用者或作業人員被動連結產品關係，而是產品與產品間主動的聯結溝通協調。
無線傳輸技術，5G行動通訊主張低延遲性、低耗能、高傳輸率，傳輸率透過密集的基地台、增加頻寬以及使用MIMO技術來提升傳輸率，使用蜂巢式網路、
集中式網路架構來達成更優異的無線傳輸。
在功率轉換領域方面，由於矽基技術發展已到盡頭，寬带隙半導體需要更加的解決方案，因此氮化鎵和碳化矽正在快速發展，它們都能實現更多積體電路、表現更高頻率及承受更高電壓，因此，與矽元件相比，氮化鎵及碳化矽元件在整個電子市場越來越被廣泛使用。
國內行動物聯網傳輸技術的專利，主要偏重在生活應用層面，大體上為「車輛物聯」及「傳輸方法改善」兩類，持續在這兩類應用推動國內物聯產業。

Wireless sensor networks are growing rapidly, opening up the Internet of Things,
living standards have also improved, intelligent family, intelligent learning, transportation, remote monitoring and so on. The Internet of Things (IoT) has a high degree of privacy, complete coverage, reliability, and low latency, all of which are important issues leading to the Internet of Things.
At present, the mobile Internet of Things to LPWAN-based, with long-distance, power-saving characteristics, LPWAN technology is LoRa, Sigfox and NB-IoT, those three technology have different characteristics. Mutual cooperation between those three technology is high efficiency to lead the future development.
Internet of Things technology, sensing technology, network communication technology, cloud service technology, the product is no longer through the user or operator passively linked product relations, but the product and product actively linked communication and coordination.
Wireless transmission technology, 5G mobile communication advocates low latency, low energy consumption, high transmission rate, transmission rate through high density base stations, increase bandwidth and the use of MIMO technology to improve transmission rates, the use of cellular networks, A centralized network architecture for better wireless transmission.
In the field of power conversion, the development of silicon-based technology has come to an end, nitride technology is accelerating, nitride and silicon carbide are broadband gap semiconductor solutions, they can withstand higher voltages, higher frequencies and achieve more integrated circuits than silicon components, so silicon carbide and nitride components are widely used throughout the electronic market.
Domestic action Internet of Things transmission technology patents, mainly focused on the life application level, generally for the "vehicle property" and "transmission method improvement", continue to promote the technology and application of the industry forward.
