Hello everyone！
Today, I'm going to share with you details about the types of Huawei base stations.
What are the types of Huawei base stations?
By series, they can be classified into:
3900 series base stations
BTS3900
BTS3900L
BTS3900A
BTS3900AL
BTS3900C
DBS3900
5900 series base stations
BTS5900
BTS5900L
BTS5900A
BTS5900AL
DBS5900
As mentioned above, many base stations have letters after them. Do you know what these letters mean? Next, I will introduce the naming rules of base stations.

Macro base stations and distributed base stations
Based on application scenarios, base stations can be classified into macro base stations and distributed base stations.
Macro base station
A macro base station is usually a base station installed on a tower. This type of base station is large, carries a large number of users, and covers a wide area. Generally, the base station can reach tens of kilometers.
A macro base station consists of a BBU and an RFU.

The distributed base station divides the traditional macro base station equipment into two functional modules according to functions. The baseband, main control, transmission, and clock functions of the base station are integrated into a module called the baseband unit. The baseband unit is small and the installation position is flexible. Integrates the IF and RF modules, such as the transceiver and power amplifier, on another remote RF module, and installs the remote RF unit at the antenna end. RF units and baseband units are connected through optical fibers to form a new distributed base station solution.
A distributed base station consists of a BBU and RRUs/AAUs.
Comparison between macro base stations and distributed base stations
In general, the performance of distributed base stations is better than that of macro base stations. Compared with macro base stations, distributed base stations have the following advantages:
1. Easy site selection for distributed base stations
In urban network construction, operators face difficulties in site selection and tight equipment room space. Distributed base stations feature low costs, strong environment adaptability, and easy engineering construction.
2. Distributed base stations save more space
Distributed base stations usually use RRUs and require small space. Because the RRU can be remotely installed, the RRU can be installed almost anywhere. In a distributed base station, the BBU and RRU are separated. The indoor BBU processes baseband signals only and does not have RF components, especially the power amplifier module. Therefore, it has the characteristics of small size, light weight, low power consumption, and easy installation. Compared with macro base stations, distributed base stations save equipment room space, reduce network construction costs, and speed up network construction. In addition, the distributed base station uses high-efficiency power amplifiers, which reduces power consumption of other auxiliary facilities such as air conditioners, and is characterized by energy saving and emission reduction. The ports at both ends of the base station are connected by optical fibers, which reduces power consumption.
3. More flexibility
In terms of service development, data services will be characteristic services of mobile communications, and the bandwidth occupied by data services is tens or even hundreds of times that of voice services. This requires more flexible coverage solutions to adapt to service development. For emerging services, because of high transmit power and high network density, operators can use distributed base stations to provide better hardware platforms for data services that require high bandwidth. With the rapid development of mobile network construction, operators' requirements for fast, flexible, and low-cost network deployment make mobile distributed base stations become the trend and mainstream of network construction.
4. Wider application of distributed base stations
Since the 3G network era, distributed base stations have been applied on a large scale. For example, 3G TD-SCDMA, WCDMA, and CDMA2000 have distributed base station products.
5. Cost Savings
In contrast, the macro base station uses 7/8 feeders to connect the RFUs and antennas, and the distance is long. However, 7/8 feeders are expensive and cost relatively high. In distributed base stations, RRUs can be installed remotely. RRUs are connected using 1/2 feeders, which is low in cost. If the RRU is installed on a tower, the length of feeder 1/2 is shorter.
Therefore, most base stations in use today are distributed base stations.
