我國電信為特許事業,高鐵沿線的行動通訊品質改善,須由行動通信業者投資辦理。
彰化員林以北高鐵隧道群路段的4G行動通訊品質改善方式係由5家電信業者共同出資採共構方式建置基地台及佈放漏波電纜,為配合臺北市舉辦之世界大學運動會及提升高鐵沿線行動寬頻4G通信品質,目前在行政院科技會報辦公室、交通部、國家通訊傳播委員會等指導下,電信業者全力配合日夜趕工,除臺北至南港地下段已於106年3月完成4G通訊改善外,電信業者預計將於106年7月底前完成新竹以北隧道段之高鐵沿線4G通訊建置,106年12月底前完成高鐵沿線隧道段4G通訊建置,後續再持續進行訊號優化。
至於,彰化以南高架段部分則由各電信業者利用原有的基地台增置設備,或自行增建基地台方式辦理。目前仍需要增加基地台數量,以提高行動寬頻訊號涵蓋比率,行政院科技會報辦公室已持續定期召開會議並協助行動通信業者辦理用地取得後架設通訊站台,行動通信業者亦持續進行訊號優化,將可提升高鐵沿線行動寬頻4G通訊涵蓋率。

As the telecom business in Taiwan is a franchise business, improvement of the mobile communication quality on the HSR must be invested and carried out by the telecom companies in the country. The 4G mobile communication quality improvement plan for HSR tunnel sections north of Yuanlin, Changhua County is jointly invested by five telecom companies to build base stations and lay out leakage cables. In cooperation with the XXIX Summer Universiade that will be held in Taipei City and the promotion of 4G communication quality along the HSR, the telecom operators are fully engaged in day and night operations with the guidance of the Board of Science and Technology of the Executive Yuan, MOTC and National Communications Commission. Besides the 4G communication improvement for the underground section from Taipei to Nangang that has been completed in March, 2017, the 4G communication installation for tunnel sections north of Hsinchu is expected to be completed by end of July, 2017 and the remaining tunnel sections of the entire line is expected to be completed by end of December, 2017. Then, signal optimization will be carried out.
As for the elevated sections south of Changhua, the telecom operators will install additional apparatus based on original base stations or install new base stations respectively. There is still a need to increase the number of base stations to increase mobile broadband coverage ratio. The Board of Science and Technology has been holding meetings on a regular basis and has assisted the mobile operators in setting up communications sites. On the other hand, the telecom companies continue to optimize the signal to enhance the mobile broadband 4G communication coverage along HSR route.
