人類的日常活動有50 %以上的時間是在室內,故行動電話使用者大部份之話務量將發生在室內。因此,對電信營運商而言,更應該要充份考慮室內用戶的業務面的需求,提升客戶滿意度,開拓出更大量的話務量,進而增加公司營收。台灣目前有很多大型商辦、百貨公司、大型賣場,從2G / 3G時代因話務需求佈建了室內天線分流系統。但因2G/3G行動通訊天線系統並非使用Multiple-Input Multiple-Output (MIMO)之技術,故佈建方式均使用(Single-Input Single-Output) (SISO)方式。本論文將以中華電信為例,提出一種低成本且能提升既有(Single input Single output) (SISO)室內天線分流系統效能之方法,最後將與其他各種改造方法進行比較。

People spend more than 50% of their daily time to stay indoors, which leads to the vast majority mobile data traffic. Therefore, Telecom service providers should fully consider indoor end-user service experience, enhance end-user satisfaction, and increase end-use revenue. Currently there are a lot of large-scale commercial offices, department stores, and shopping malls in Taiwan. Due to the traffic requirement and implementation in 2G/3G cellular systems, indoor distributed antenna system with Single-Input Single-Output (SISO) technology is developed. However, the 4G cellular system, Multiple-Input Multiple-Output (MIMO) technology, is not considered. Accordingly, this thesis uses the Chunghwa Telecom as an example to propose a low-cost capacity improvement scheme via existing 4G SISO distributed antenna systems. Through experimental investigation, the proposed scheme is shown to be cost-efficient compared with other methods.
