針對目前市場上現有電信公司提供4G LTE網路系統服務，用戶使用手機上網速率感受度不滿意，來進行網路效能優化的問題分析及改善，強調各電信業者除了一直新增基地台加強區域訊號涵蓋及進行現有頻寬的擴頻，真的就可以達到預期的網路效能最佳化嗎?本論文中將進行說明並提供優化策略來執行驗證，針對在欲改善的區域，新增4G站台的同時，需進一步確保新建站台的建設品質，涵蓋射向有效達到目標區，進一步對此區域所有站台進行優化的調整，以避免訊號涵蓋重疊區域過大，造成站台資源浪費，站台無法發揮最大效能，該網路頻寬無法有效率讓用戶使用，造成用戶於尖峰時段使用手機上網容易壅塞，透過本論文提供的4G LTE 區域優化策略，來有效提升網路效能，改善此問題。

The existing telecommunication company provides the LTE network system, in view of the present market ,the user use handset data speed requirement susceptibility is unsatisfied, carries on the question discussion and the analysis of network optimization effectively, is not always add base station to strengthen the signal coverage signal covering continuously, bandwidth spread spectrum, you can achieve the optimization of network efficiency, must while increase the 4G base station , and further guarantees the newly built base station construction quality to be good. covering to reach the target area effectively, and synchronized to all of the site to cover the optimization adjustment to avoid the signal coverage overlap area too large, resulting in waste of network resources, the network resource can’t provide the maximum efficiency, will not be able to share the bandwidth average users, Users on the data requirement to use peak hour, The use susceptibility is not good, the penetration report will provide the LTE platform region optimization strategy, will come the effective promotion network potency, will improve this question.
