摘要

第三代(3G)行動通訊的應用服務已在先進國家蓬勃發展，歐盟針對行動數據傳輸的費率訂定上限，因此預期未來歐盟國家消費者對行動上網的資料傳輸需求將大幅成長，以及多元化的應用及服務將整合至寬頻行動網路之中。第四代(4G)行動通信系統將會是由LTE或是WiMAX兩者中哪個技術標準勝出？本研究以產業生態系理論為基礎，建立一個評估LTE和WiMAX形成數位產業優劣態勢的理論框架。本研究結果指出雖然WiMAX在標準與佈建上稍早於LTE，但LTE的優勢是能借力於現有3G生態系的豐沛資源與高市佔率所衍生的規模經濟，將演變成為4G行動通信產業的主流。

The number of Third Generation (3G) mobile telecommunications users started picking up even in the emerging markets. The European Union (EU) anticipated significant growth in the mobile internet market in the European countries as abundant broadband mobile applications and services are becoming available. There have been long debates on the competition between WiMAX and LTE as the mainstream wireless access standard for the Fourth Generation (4G) mobile communications system. Based on the industry ecology theory, this research proposed a theoretical framework to assess the merits and drawbacks of LTE and WiMAX. The results showed that although WiMAX has certain technological advantages than LTE, but that alone can not change the course of the global 3G operators evolving their infrastructures from WCDMA/HSDPA to LTE.
