摘要： The present invention discloses a base station system, including an indoor part and a remote RF subsystem (RRS). The indoor part includes a RIU, a CCU, a BBU, a GPSU and a local interface unit. The RRS includes a remote interface unit, a RF transceiver unit (TRU) and an antenna. The local interface unit and the remote interface unit are for signal intercommunicating between the indoor part of the base station and the RSS. The TRU is a RF transceiver module of the conventional RFU, for amplifying an analog RF signal from the remote interface unit and transmitting the signal to the antenna. By flexibly selecting between an optical cable and an If cable, the interface unit of the present invention provides a digital baseband remote manner and an IF remote manner. According to the structure of the base station of the present invention, the number of the base station sites and the network operating cost decreases; on the other side, since one base station may cover a cell by smart antenna with only one optical cable or IF cable, the difficulty in mounting is reduced.
