為改善前述狀況，爰即辦理三重端出土段至A3高架段及A2車站無線電訊號補強工程，改善訊號不良情形。除於A2站內新設1組基地台，強化站內無線電收訊品質，並於車站屋突/軌旁增設2部室外天線，分別往A1 ~ A2出土段及A2~A3高架區域方向發射訊號；另於A2站至A1站出土段間之2轉彎處，增設2部平板天線強化該路段之訊號品質。本標業於107年3月5日完成設備安裝後，陸續進行SIT、SAT，並於107年3月12日共同確認已改善完成。
The signal transmitted by the radio base station in New Taipei Industrial Park Station (A3) covers the turning area of the daylighting section of Sanchong Station (A2) and the section from Taipei Main Station (A1) to Sanchong Station (A2). With the rapid development of the city, the front of the base station launching antenna in New Taipei Industrial Park Station (A3) is blocked by new high-rise buildings, resulting in the blockage of reception at the turning area of the daylighting section of Sanchong Station (A2) and the section from Taipei Main Station (A1) to Sanchong Station (A2). In addition, after the completion of the Y19 Station construction of the Circular Line, the signal blockage is bound to become more serious.Therefore, an additional base station will be installed in A2 Station under the existing system structure.
In order to improve the situation mentioned above, we will deal with the unreliable signal from the Sanchong daylighting section to the elevated section of the New Taipei Industrial Park Station (A3) and also the Sanchong Station (A2) with a radio signal reinforcement project. Aside from setting a new base station in Sanchong Station (A2) to strengthen in-station radio reception quality, 2 sets of outdoor antennas will be installed at station roof protrusions and wayside to respectively launch signals to “Taipei Main Station (A1) to Sanchong Station (A2) daylighting section” and “Sanchong Station (A2) to New Taipei Industrial Park Station (A3) elevated section”. Additionally, for the 2 turning areas from Sanchong Station (A2) to Taipei Main Station (A1) daylighting section, 2 plate antennas will be added to strengthen the signal quality of this section. This equipment installation of project has been completed by Mar. 5, 2018. Followed by SIT and SAT tests, the project improvement has confirmed to be completed by Mar. 12, 2018.
