  • Publication number: 20090215493
    Abstract: The present invention discloses a remote radio unit and a base station system. The remote radio unit includes an active part and a passive part, where the active part and the passive part are placed respectively on an active module and a passive module that are independent of each other and the active module and the passive module are connected via a pluggable connecting device. Because the passive part is more reliable and less liable to breakdown than the active part, when the active part needs to be repaired, it is unnecessary to dismantle the entire unit. Therefore, the repair is easier and faster and the repair cost is lower. The operation reliability of the base station system is also improved.

  • Publication number: 20090207094
    Abstract: An antenna is connected to a connector disclosed in the present disclosure, and the connector has a clamping slot adapted to fix a radio remote unit (RRU). A clamping slot tight side may be set on the connector to fasten the RRU, and an RRU fastening hole may be set on the connector to fasten the RRU. An RF apparatus integrated with a connector is also disclosed. According to the present disclosure, the antenna and the RRU are fixed to the connector. This makes it unnecessary to provide additional spaces and supports for installing the RRU. Hence, the RRU can be installed in a proper position and the installation costs can be reduced. In addition, the distance between the antenna and the RRU is shortened. Thus, the cable (when necessary) between the antenna and the RRU is shorter than that in the prior art. This greatly reduces signal transmission losses.
