通訊使資訊能夠有效傳遞，通訊的穩定、傳輸的距離以及可使用的傳輸速度對於國家及社會之穩定有著重大的影響，而美國CISA（Cybersecurity and Infrastructure Security Agency）更將能源、水、運輸與通訊並列四大 Lifeline sectors，任一元素的缺乏對於國家、社會及家庭的影響將不可估量。而本篇文章所著重的通訊更是尤其重要。試想在國家緊急狀態下，不管是颱風、土石流、地震等自然災害，或者是軍事、國安等人為衝突，又或是2019年的大規模新興傳染病 COVID-19 都非常仰賴通訊的聯通，而若政府單位所發布的資訊或是民眾之間的訊息的交換弱勢無從被得知，後果將不堪設想。
目前全球的通訊網路分佈為地面網路（Terristerial network）以及非地面網路NTN( none-terristerial Network)為主要分界，也就是地與天的分別，Terristerial Network又以4G/5G 配合海底電纜等網路為大宗，而天上的NTN netowrk則以衛星作為傳輸的載體，但由於新一代3GPP 標準以及終端設備的革新，使得通訊的邊界愈加模糊，甚至合而為一。在衛星通訊當中又以高、中、低軌衛星作為主要分界點，從過往的分軌經營慢慢進行到多軌融合，未來也以無邊界軌道作為發展前景。此篇研究將基於波特五力中所使用的既有競爭者之強度、淺在進入者威脅、替代品威脅、買方議價力以及供應商議價力作為基底加上策略群組，整合全球衛星通訊系統的技術、頻譜與產業模式，深入探討全球衛星通訊產業的發展趨勢與技術演進路徑。透過分析全球市場結構、主要業者的技術能力與策略佈局，提供對策略規劃與未來技術融合趨勢的臺灣企業提出深入見解。
再延伸結合衛星通訊中的人工智能自主決策、以及加密通訊等技術發展脈絡將能協助探討未來可能的通訊架構與跨域應用場景，並且基於臺灣衛星通訊相關題材公司於全球市場銷售概況以及終端延伸應用例：人工智能（機器學習）、資安、量子技術與資料中心對產業模式的潛在發展可能性，也同時研究在國家政策下臺灣本地企業如中華電信、工研院、中科院、TASA（Taiwan Space Agency）及私人公司在推動產業自主性與強化韌性通訊方面所扮演的關鍵角色，此篇研究也將著重將衛星通訊的核心：通訊系統平台作為主要比較以及分析的中心，並且推估未來臺灣衛星通訊產業可延伸及擴大的銷售市場。最終回歸波特五力分析各不同商業模式對本土企業在市場中的定位進行評估，並提出具體策略建議，以協助政府與產業界在變動快速的國際太空競局中掌握關鍵先機，建立具前瞻性的發展藍圖。

Communication enables the effective transmission of information. The stability of communication systems, the distance over which information can be transmitted, and the available transmission speed all have profound implications for national and societal stability. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) categorizes energy, water, transportation, and communications as the four core lifeline sectors. The absence or failure of any one of these elements would result in incalculable consequences for nations, societies, and households alike. Among them, communication is of particularly critical importance.
In times of national emergency—whether caused by natural disasters such as typhoons, landslides, and earthquakes; by human-induced crises related to military conflict or national security; or by global public health events such as the large-scale emerging infectious disease outbreak of COVID-19 in 2019—society relies heavily on resilient and continuous communication connectivity. Should information released by government authorities or the exchange of messages among the public become inaccessible or disrupted, the consequences would be catastrophic.
At present, global communication networks can be broadly divided into terrestrial networks and non-terrestrial networks (NTN), representing the distinction between ground-based and space-based infrastructures. Terrestrial networks are primarily composed of 4G/5G mobile systems integrated with submarine cable networks, while NTNs rely on satellites as their primary transmission medium. However, advancements in next-generation 3GPP standards and innovations in user terminal equipment have increasingly blurred the boundaries between these domains, driving convergence toward an integrated communication ecosystem.
Within satellite communications, systems are traditionally categorized into geostationary orbit (GEO), medium Earth orbit (MEO), and low Earth orbit (LEO) satellites. The industry has gradually evolved from segregated, orbit-specific operations toward multi-orbit integration, with future development trending toward a seamless, boundaryless orbital architecture.
This study adopts Porter’s Five Forces framework—examining the intensity of existing competitors, the threat of potential entrants, the threat of substitute products, the bargaining power of buyers, and the bargaining power of suppliers—augmented by strategic group analysis. By integrating technological capabilities, spectrum resources, and industry business models across global satellite communication systems, this research provides an in-depth examination of industry development trends and technological evolution pathways. Through analysis of global market structures, as well as the technological competencies and strategic positioning of major industry players, this study offers insights into strategic planning and future technology convergence trends, with a particular focus on implications for Taiwanese enterprises.
Furthermore, by incorporating developments in artificial intelligence–driven autonomous decision-making and encrypted communications within satellite systems, this research explores potential future communication architectures and cross-domain application scenarios. Based on the global sales performance of satellite communication business in Taiwan–related firms and extended terminal application examples—such as artificial intelligence (machine learning), cybersecurity, quantum technologies, and data centers—the study evaluates the potential evolution of industry business models.
In parallel, this research examines the roles played by Taiwanese public and private organizations—including Chunghwa Telecom, the Industrial Technology Research Institute (ITRI), the National Chung-Shan Institute of Science and Technology (NCSIST), the Taiwan Space Agency (TASA), and private enterprises—in promoting industrial autonomy and strengthening resilient communication capabilities under national policy frameworks. Central to this analysis is the satellite communication system platform, which serves as the primary unit of comparison and evaluation. The study further estimates the potential expansion of sales markets for Taiwan’s satellite communication industry.
Finally, by returning to Porter’s Five Forces framework, this research evaluates how different business models influence the market positioning of domestic enterprises and proposes concrete strategic recommendations. These insights aim to assist both government and industry stakeholders in seizing critical opportunities amid rapidly shifting international space competition and in establishing a forward-looking development blueprint for the future.
