以5G技術導入企業專網之研究

Abstract

5G發展以來被全球視為關鍵發展要素，我國行政院於108年公告「台灣5G行動計畫」，計畫內5大推動方向中第一條即是推動5G垂直應用場域實證，同時亦規劃與德國、日本與英國等國家同步，將釋出專用頻段提供專網使用，期望落實真正展現5G效能，從而提高產業競爭力，而這也代表著5G專網對於5G發展及國家的重要性。本研究係針對決策者在規劃或推廣5G專網時，主要考量的關鍵要素進行分析與探討，透過文獻資料、研究機構與專家學者之研究，整理出本研究所設定之四大構面及十八大項準則來制定問卷題目，邀請於5G專網具備相關實務經驗之產業界專家共25位進行訪談，並依據專家之背景區分電信產業鏈上中下游不同領域，分別為電性營運商、電信設備商及系統整合商等三組，並經訪談、問卷填寫回收後，再彙整專家的意見，利用分層式決策分析法模型 (HDM) ，計算各構面與準則間相對權重，並進行重要性排序。研究結果發現各群組專家於構面權重排序有所不同，但於5G專網應用場域及5G專網政策這兩項構面均為權重較高的因素。準則部分，於5G專網政策中，頻率使用費為較多專家認為較重要的因素。5G專網應用場域部分三組專家則一致認同智慧工廠會是最重要的關鍵因素。5G development has been regarded as a key development element worldwide. The Executive Yuan officially approved the"Taiwan 5G Action Plan" in 2008, the first of which is to promote 5G vertical application field demonstration. This represents the importance of 5G private networks to the development of 5G and the country. This study analyzes and examines the key factors that decision makers consider when planning or promoting 5G private networks. Total of 25 industry experts with relevant practical experience in 5G private networks were invited to conduct interviews, and according to the background of the experts, different fields in the upper, middle and lower reaches of the telecommunications industry chain. Three groups including telecom equipment vendors, operators and system integrators, and after interviews and questionnaires are filled out and the relative weights of each aspect and criterion are calculated by using the Hierarchical Decision Analysis Model.The results of the study found that experts in each group have different rankings , but 5G private network application field and 5G private network policy are factors with higher weights. In the standard part, in the 5G private network policy, the frequency usage fee is considered by many experts to be a more important factor. The three groups of experts in the 5G private network application field unanimously agreed that smart factories will be the most important key factor.
