The base station of 2G/3G/4G can be the same, but the equipment in the equipment room is different. The main difference is that the frequency of the antenna is different. Due to the different implementations of 3G/4G by various operators, some antennas are the same as 2G, while others are wider and larger than 2G. However, there are currently shared antennas for 2G/3G/4G, and the difference cannot be seen from the appearance, mainly due to the difference in the internal structure. 2G antennas are usually able to generate one beam, while 3g4g generally use smart antennas to generate multiple beams to track users.

2G base station: GSM: 900/1800MHz; CDMA: 800MHz;

3G base station: CDMA2000&WCDMA: 2100MHz; TD-SCDMA: 1880-1920, 2010-2025, 2320-2370MHz;

4G base station: TDD-LTE: 2320-2370, 2570-2620MHz; FDD-LTE: unknown frequency band plan.

With the same coverage, the ratio of the number of 2G, 3G, and 4G base stations is about 50:10:1. Because the transmit power of 2G, 3G and 4G base stations is gradually increased, so to cover the same range, the number of 4G is much less than that of 2G and 3G.

The base station or public mobile communication base station is a form of radio station, which refers to the radio transceiver station that transmits information with the mobile phone terminal through the mobile communication switching center in a certain radio coverage area. The construction of mobile communication base stations is an important part of the investment of my country's mobile communication operators. The construction of mobile communication base stations is generally carried out around such elements as coverage, call quality, investment efficiency, ease of construction, and ease of maintenance.
