鑒於國際之通訊技術發展迅速，各國對5G專網的重視程度與需求日益增強，將5G專網的建設與部署列為重要的發展目標。我國目前開放的頻段於「4.8-4.9 GHz」之間，專門使用在「5G專頻專網」的行動寬頻專用電信網路，由數位發展部負責，主要是由場域主申請執照與設置專網。由於我國5G專頻專網推出之後，企業對於相關內容並不熟悉，因此本研究目的是先分析我國5G專頻專網申請之現況，並探討業者導入5G專頻專網的考量點與面臨的挑戰，接著進行不同產業導入的可行性評估，希冀使我國有更多企業導入5G專頻專網。
本研究採用文獻分析法與專家深度訪談法，透過蒐集國外在應用5G專網所遭遇的種種挑戰，並評估我國現況分析與考量我國的環境與規範後，設計針對受訪者的調查問項，面向分為四種，分別為技術導入面、網路資訊安全面、法規面、財務營運面。根據文獻之現況分析與結合專家訪談的方式，修正出後續的研究成果，綜合探討出我國目前導入5G專頻專網所遭遇到的挑戰，提出產業合適的可行性評估，以支持政府與企業思考導入決策過程與結果。
本研究發現目前國內外多數案例以實驗性質為主，全面導入之企業並不多。且結果顯示我國多數企業導入5G專頻專網時多半仍以財務營運面為首要考量，企業認為導入5G專頻專網的成本太高，許多中小型企業也無法負擔後續的維運成本，並且更看重投資報酬率的成長性。另外企業於導入時也會面臨企業文化、人才、整合服務能力、需求、設備成熟度和補助費用等挑戰，造成我國企業遲遲無法提升導入新技術的意願。根據結果進行可行性評估，研析出導入5G專頻專網可行程度較高的以高科技或大型製造業為主，其他產業仍受限法規、財務與場域等等之限制。

With the rapid development of international communication technology, the importance and demand for 5G non-public network is growing globally. Our country has allocated the 4.8-4.9 GHz band for "5G Dedicated Spectrum Non-Public Network" overseen by the Ministry of Digital Affairs. The primary applicants for licenses and network setup are field operators. Since businesses are not familiar with the 5G dedicated spectrum non-public network, this study aims to analyze the current application status, explore the considerations and challenges faced by operators, and assess the feasibility of adoption across different industries, with the goal of encouraging more enterprises to adopt this network.
This study uses literature analysis and expert in-depth interview. Designed survey questions focusing on technological implementation, network information security, regulations, and financial operations.
The results of this study found that most domestic and international cases are primarily experimental, with few enterprises fully implementing the technology. Financial operations are the main consideration for most enterprises, with high costs being a significant barrier. Small and medium-sized enterprises struggle with maintenance costs and are concerned about return on investment. Additionally, challenges such as organizational culture, talent, service integration capabilities, demand, equipment maturity, and subsidy costs affect adoption. The feasibility assessment suggests that high-tech or large manufacturing industries have a higher likelihood of adopting 5G Dedicated Spectrum Non-Public Network, while other industries face regulatory, financial, and field limitations.
