隨著長期演進通訊技術（LTE）獲得龐大4G市場成就，多樣的技術和應用都渴望能利用到下一代5G電信。然而，頻譜是稀少的自然資源，故政府應根據國家電信政策的方向，針對5G技術和應用分配足夠的頻譜。國際電信聯盟（ITU）已提供了頻譜需求預估模型ITU-R M.2290，然而國際電信聯盟並沒有公開發布基於ITU-R M.2290模型的實作系統，以提供進一步評估、分析及修正。因此，本文提出了模組化頻譜預估系統（MSE），該系統提供使用者導向的介面及模組化功能，依據不同的市場和技術特徵來計算頻譜需求。MSE的貢獻為（1）提供台灣不同的5G頻譜規劃之效果；（2）提供使用者介面，幫助決策者快速找出頻譜預估資訊；（3）提供模組化“隨插隨拔”的系統架構，能協助頻譜政策研究人員簡易實作出欲探討預估頻譜需求的新方法。透過MSE系統的GUI介面設定，計算出臺灣在2020年頻譜需求量，並發現經由不同的城市鄉村區域設定中能供提供政府不同的頻譜規劃效果，有效的增加功能的延伸以及縮小頻譜預估研究的複雜問題。

As Long Term Evolution (LTE) cellular technology acquires enormous 4G market success, various technology and application specifications are eager to utilize the next generation, 5G, telecommunication. Spectrum, however, is a scarce natural resource, so the government should deliberately make efforts to distribute sufficient spectrum to 5G technologies and applications, in accordance with the direction of national telecommunication policies. The International Telecommunication Union (ITU) has provided a spectrum requirement estimation model, ITU-R M.2290. However, ITU did not release an implementation system based on ITU-R M.2290 model for further evaluation, analysis, and modification. This thesis therefore proposes a Modularized Spectrum Estimation System (MSE), which provides a user-friendly interface and modularized functionalities to estimate the spectrum requirement under considering various market and technology characteristics. The contributions of MSE are (1) providing spectrum requirement analysis and offering different 5G spectrum plan alternatives in Taiwan; (2) providing a user-friendly interface, which allows policy makers to access the spectrum estimation information quickly and comprehensively; and (3) providing a modularized “plug-and-play” system architecture, which can help spectrum policy researchers to easily implement their idea and explore new ways on estimating spectrum requirement.
