國軍通信骨幹系統為國軍C^4ISR指管系統情資傳遞主要傳輸平臺，近來發現國軍現用系統因設備本身頻寬與傳輸功能限制及消失性商源等問題，難以滿足未來數位化戰場高流量的情傳負荷。本次研究目的即藉由文獻探討及分析各國5G行動網路技術發展及其軍事應用，藉以提出我國運用5G行動網路強化國軍通信骨幹系統效能之建議策略，全球先進國家如美國、南韓及中國大陸等，均紛紛投入大量資源以強化5G行動網路在各領域的發展運用，我國亦持續推動5G行動專用網路建置，其專網具有獨立運作，不易受公共網路壅塞影響等特性，相對於我軍事通信運用之保密要求，更加凸顯有其發展的必要，5G行動網路所帶來之傳輸速率與穩定效應，能獲得對戰場態勢的高度感知能力。建構低延遲、高效能及以IP應用服務為主體的5G行動通信網路，正可成為國軍現有實體骨幹系統「多元」及「備援」之傳輸手段。

The R.O.C Forces backbone communication system is the main platform for transmitting the tri-service's C^4ISR information. Recently, it has been found that the current system is difficult to meet the high-traffic transmission load of the future digital battlefield due to the limitations of the bandwidth and transmission functions of the equipment itself, as well as the disappearance of commercial sources. The purpose of the study is to discuss and analyze the development of 5G mobile network technology and its military applications in various countries through literature, so as to propose strategies for the R.O.C to use 5G mobile networks to strengthen the performance of the R.O.C Forces' communication backbone system. The world's advanced countries such as the United States, South Korea and Mainland China and other countries have invested a lot of resources to strengthen the development and application of 5G mobile networks in various fields. The R.O.C has also continued to promote the construction of a 5G mobile private network. Its private network has the characteristics of independent operation and is not easily affected by public network congestion. Compared with the confidentiality requirements of the R.O.C Forces communication applications, it is more necessary to develop. The transmission rate and stability effect brought by the 5G mobile network can obtain a high degree of awareness of the battlefield situation. The construction of a low-latency, high-efficiency 5G mobile communication network with IP application services as the mainstay can become one of the “multiple” and “backup” transmission methods for the existing backbone systems of the R.O.C Forces.
