    摘要: 因微波通訊屬無線傳輸,不需靠傳輸介質傳送訊號,因此系統建設的時間較有線傳輸通訊系統快速且花費相對較少,雖傳輸頻寬不如光纖通訊,但運用於非屬幹線網路的中繼線通訊尚稱足夠,因此運用微波通訊佈建中繼基地站實為經濟有效之方式,然現今實務用於評估基地站佈建可行與否,仰賴現場實機測試,但如此需耗費相當多的時間與人力,有需要加以改善及簡化。
    本文設計一套用以評估佈建可行性的模擬流程,並利用實機測試驗證其模擬結果是否正確,目標是取代現行實機測試之實務做法,提高微波中繼基地站的佈建效率。
    The microwave communication is a kind of communication method using wireless transmission, so there is no need to use transmission medium. Owing to the specialty, it takes less time and cost than wire transmission when establishing system. Although the transmission bandwidth is not as good as fiber optical communication-the best wire transmission type used in backbone network, it is sufficient for the communication flow of trunk circuits. Therefore, using microwave communication to establish trunking base station is an economical and efficient method. Nevertheless, the feasibility evaluation of microwave trunking base station establishment in practical depends on an on-site factitious test. This test takes too much time and labor cost to complete the evaluation. So it needs to be improved and simplified.
    This thesis designs a simulation procedure to evaluate the feasibility, and verify the result by on-site factitious test. The goal is replacing the factitious test to increase the establishment efficiency.
