Abstract

The invention relates to the technical field of communication, and discloses a distributed base station, comprising a power system, a power supplying device and at least two radio remote units (RRU), wherein one end of the power supplying device is connected to the power system, and the other end thereof is connected to the at least two RRUs; the power supplying device is used for receiving power output by the power system, and providing the power to the at least two RRUs; and the distance between either of the RRUs connected to the power supplying device and the power supplying device is less than the distance between the RRU and the external power system. By adopting the distributed base station, the length of a DC power cable is reduced in laying the DC power cable, and engineering expenses and later protection costs are saved. In addition, the invention further provides a communication system.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a distributed base station and a communication system. Background technique [0002] The wireless communication base station includes a distributed base station. The distributed base station is composed of BBU (BuildingBasebandUnit, baseband processing unit), RRU ((RadioRemoteUnit, radio remote unit) and antenna. When actually building a network, the power supply of the radio remote unit DC power is provided by the remote power system. figure 1 As shown, the remote radio unit is connected to the remote power system through a DC power cable. Usually, the remote power supply system is 40 to 100 meters away from the remote radio unit, or even farther away. [0003] In the construction of a wireless communication network, after the initial construction of a distributed base station, the number of remote radio units will be gradually increased in the next few ...
