 直放站提供了一種負擔得起的解決方案，以解決由於建築障礙物引起的信號衰落和衰減而導致的室內信號覆蓋問題。而且它易於安裝和維護，可以幫助運輸公司快速退貨。

中繼器充當BTS和移動台之間的中繼。它通過施主天線從BTS接收最強的信號，將其線性放大，然後通過室內信號分配系統將其重新傳輸到弱/盲區。並且移動信號也被放大並經由相反的方向重發到BTS。

轉發器可以放大自定義頻段內的信號。

The RF Repeater is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality. And its easy installation and maintenance can help carrier get fast return. 

The repeater is working as a relay between the BTS and mobiles. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
