摘要： 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.

摘要： The present invention discloses a distributed base station system as well as its networking method and base band unit. In this system, the base band unit (BBU) and RF unit (RFU) of the base station are separated, and the RFU is equipped with base band RF interfaces for interconnecting the BBU and transmitting data information, thereby forming the base station. Based on the separation of the BBU from the RFU, the BBU capacity is further divided at the same time, and every unit is also arranged independently. The BBU networking and capacity expansion may be achieved with capacity expansion interfaces and base band RF interfaces provided by BBU interface units in flexible and convenient ways.
