DC Power system in communication base stations

Wireless communication base stations generally consist of the following main components:

1. Antenna feeder system: including antennas and feeders. The antenna is responsible for transmitting and receiving wireless signals, while the feeder is used to connect the antenna to the main equipment of the base station, achieving signal transmission. Different types of antennas are suitable for different coverage scenarios and frequency bands.

2. Base station main equipment: such as baseband unit (BBU), radio frequency unit (RRU), etc. BBU is responsible for baseband processing of signals, while RRU is responsible for transmitting, receiving, and processing RF signals. The two work together to complete functions such as modulation, demodulation, encoding, and decoding of signals.

3. Transmission system: responsible for data transmission between the base station and the core network, commonly using methods such as fiber optics and microwave, to ensure that user data collected by the base station can be accurately transmitted to the core network, while conveying core network instructions to the base station.

4. Power system: including mains power supply, rectification equipment, battery pack, etc. The mains power provides the main power for the base station, and the rectification equipment converts AC power into DC power for equipment use and charges the battery. The battery ensures the continuous operation of the base station during mains power outages.

5. Computer room supporting facilities: such as air conditioning used to regulate the temperature and humidity of the computer room, ensuring that the equipment works in a suitable environment; Firefighting equipment is used for fire prevention and extinguishing in computer rooms; The monitoring system provides real-time monitoring of the computer room environment and equipment status.

DC power systems for telecommunications provide steady energy for telecommunication facilities. They convert alternating current into direct current to prevent interruptions. Reliable power is essential, especially with the increasing demand from 5G networks that require greater efficiency.
