4G LTE可以提供高鐵乘客更快更穩定的無線網路品質。4G LTE網路覆蓋規劃是網路建置的過程中非常重要的環節，而鏈路預算(Link Budget)是網路覆蓋的規劃常用的工具。在本篇論文中，除了考量高鐵環境對於網路建置之不可抗因素之外，就網路建置規畫進行訊號強度與TCP效能預測以期可以達到理想的傳輸速率， LTE基站實際建置完成後我們也進行基本的連通測試與效能驗證，從測試結果中，我們可以發現目前各個基站的連通功能均可以正常運作之外，在新竹站南邊細胞的下行TCP效能平均能夠達到約70Mbps。藉此可以提供未來高速移動細胞規劃與佈建一個重要的參考依據。

4G LTE can provide high-speed rail (HSR) passengers the higher and the more stable wirelessnetwork quality. Coverage planning is very essential for deployment of 4G LTE and link budget is the mostcommonly tool. In addition to consider the factors could not resist for HSR environment, in this paper, weperform the predictions of signal strength and TCP performance for cell planning to achieve the desiredtransmission data rate. After the deployment of LTE eNBs are completed, we also perform the basicconnectivity testing and performance verification. From the testing results, we can find that currentattachment of each LTE eNB can work well and the downlink average TCP throughput of southern cell atHsinchu station can achieve about 70Mbps. Thereby providing an important reference of high mobility cellplanning and deployment.
