中文摘要
隨著時代與科技不斷的進步,智慧型手機變成了生活之中的必需品,無論在戶外還室內,使用手機就需要有基地台的建置,且使用者須在涵蓋範圍內接受基地台提供之服務,從早期3G時代的語音通話、流量較少的網路服務,到4G時代無線網路服務、高速網路,至今已發展至5G時代,追求著無延遲、高傳輸的服務。
在台灣電信業界中,5G行動基地台數量及涵蓋稍嫌不足,五間電信皆還在建置期,且5G高頻特性,波長較短、電波衰減大、容易受干擾、涵蓋範圍較小的影響,5G基地台的密集度需要大於4G基地台密集度,所以該如何對基地台做天線調整、訊號優化是各大電信業中最需要探討的環節。
本篇論文主要探討基地台訊號及天線優化部分,提升基地台訊號品質,解決訊號不良處。本論文研究天線優化前後之路測量測之差異,研究結果證實,調整方位角、機械角(Mechanical Tilt)、電子角(Electrical Tilt)後,使該區域訊號品質及客訴有所改善。
Abstract
With the continuous advancement of the times and technology, smart phones have become a necessity in life, whether outdoor or indoor, the use of mobile phones need to have the construction of base stations, and users must accept the services provided by base stations within the scope of coverage, from voice calls in the early 3G era, network services with less traffic, to wireless network services in the 4G era, high-speed networks, and have developed into the 5G era, pursuing latency-free, high-transmission services.
In Taiwan's telecommunications industry, the number and coverage of 5G mobile base stations is slightly insufficient, the five telecoms are still in the construction period, and the 5G high-frequency characteristics, short wavelength, large radio wave attenuation, easy to be affected by interference, small coverage, the density of 5G base stations needs to be greater than the density of 4G base stations, so how to do antenna adjustment and signal optimization for base stations is the most important link in the major telecommunications industry.
This paper mainly discusses the optimization of base station signal and antenna, improves the signal quality of base station, and solves the bad signal. This paper studies the difference between the road measurements before and after the optimization of the antenna, and the results of the study confirm that after adjusting the azimuth angle, mechanical tilt, and electrical angle, the signal quality and customer complaints in the area have been improved.
