隨著全球數據流量需求持續攀升，6 GHz頻段憑藉1200 MHz的寬頻特性，成為各國重點規劃的Wi-Fi免執照通訊頻段。為確保與既有衛星通訊業務共用頻譜並保障其權益，各國發展出室內低功率限制，以及如美國AFC（自動頻率協調）系統等動態頻譜管理機制兩種策略，以促進Wi-Fi技術與應用發展並確保不同業務的和諧共存。
本研究採用文獻分析以及情境分析法，研究結果上，分析了各國6 GHz政策發展及頻譜管理機制，並著重分析美國案例，即現有AFC服務提供商中的三間業者，高通、博通、Wi-Fi聯盟服務。研擬並提出了三間業者目前可能的AFC服務商業模式，並分析其與利害關係人監管機關、用戶、網路設備製造商等。並且透過晶片、Wi-Fi相關設備的市場來深入探討目前AFC服務之市場生態，從消費者視角檢視目前AFC服務營運狀況，並且評估其未來發展與潛力。
再研析美國現有業者之商業模式後，本研究提出AFC服務導入之評估準則，從財務面、監管面、資訊安全三大面向進行評估，供未來監管單位、學術機構衡量AFC服務導入之具體參考依據。針對台灣情境，本研究比較三種AFC服務發展模式：一是由監管單位指派專責機構主導，可確保資安與服務品質但創新速度較慢；二是開放專業機構申請營運，有利市場競爭與技術創新，如美國IC設計大廠透過AFC服務拓展晶片市場；三是不導入AFC服務，可免除相關成本與疑慮，但可能影響國內通訊產業發展。結論則建議主管機關在不同的考量下可以選擇開放業者申請、或是由公部門指派、又或是跟進歐盟的方式採取功率限制，如在資訊安全的考量上，可採取監管單位主導的方案等等。以期望能為未來主管機關、學界提供相關研究之參考。

With the growing global data traffic demands, the 6 GHz band, featuring 1200 MHz bandwidth, has emerged as a crucial spectrum resource for unlicensed Wi-Fi communications. The United States implements AFC (Automated Frequency Coordination) systems to ensure harmonious coexistence among different services.
The research analyzes 6 GHz policy developments across countries, focusing on three U.S. AFC service providers: Qualcomm, Broadcom, and Wi-Fi Alliance. The study examines their business models, stakeholder relationships, and development potential.
This study proposes evaluation criteria for AFC service implementation across three key dimensions: financial, regulatory, and information security, providing concrete reference points for future regulatory bodies and academic institutions. For Taiwan's context, the research compares three AFC service development models: first, regulatory authority-appointed dedicated institution leadership, ensuring information security and service quality but potentially slower innovation; second, opening applications to professional institutions, promoting market competition and technological innovation, as exemplified by U.S. IC design companies expanding chip markets through AFC services; third, non-implementation of AFC services, avoiding associated costs and concerns but potentially impacting domestic communications industry development. The conclusions recommend that authorities may choose between opening provider applications, public sector appointment, or following the EU's power restriction approach based on various considerations, such as implementing regulatory authority-led solutions for information security concerns. This research aims to provide reference for future regulatory authorities and academic institutions.
