How many 5g base stations can cover the whole country? How many meters can a 5g base station cover

5g what is the maximum coverage area of a base station? In fact, if I give the answer to this question, you may be surprised.

In fact, there are a large number of overlapping coverage areas in the density of base stations in urban central areas and suburbs. Removing these overlapping areas, 5g coverage requires a 5g base station of about 200-300m in urban central areas, a 5g base station of about 500m-1km in suburbs and a 5g base station of 1.5-2.5km in rural areas.

How large can a 5g base station cover

What is the coverage of the base station, that is, the transmission distance of the base station signal? Maybe there are too many factors affecting the coverage of the base station. There is almost no standard answer to this question. It belongs to 'there are 100 Hamlets in the eyes of 100 people'. Whether you ask a communication expert or a network optimization uncle, their answers to you are often different. Here may be several influencing factors for reference, and there may be no correct answer to the specific coverage.

Factors affecting base station coverage:

1. Frequency and distance

We know that the higher the frequency of the signal, the worse its diffraction ability, the greater the same loss and the longer the distance. Of course, the greater the loss. Compared with 4G, the use frequency band of 5g is higher than 4G. Without considering other factors, the coverage of its base station is naturally smaller than that of the base station in 4G period, However, this does not necessarily affect the coverage of the base station

factor.

Only from the current 5g frequency allocation, 5g is in UHF, which is theoretically worse than 4G and 3G, not to mention 2G, so 5g has a smaller coverage.

The typical values of coverage distance of 2G, 3G, 4G and 5g base stations (under the condition of good coverage in theory) are counted below.

The coverage radius of 2G base station is about 5-10km

The coverage radius of 3G base station is about 2-5km

The coverage radius of 4G base stations is about 1-3km

The coverage radius of 5g base station is about 100-300m

2. Transmit power of base station

The greater the transmission power of the base station, the greater the coverage. If 5g uses a larger transmission power, such as the 200W transmission power proposed now, the gap between the coverage and 4G may not be obvious. Simply understand, the louder we speak, the farther the corresponding transmission distance is. That's why your mother often calls you home for dinner at the door, and you can hear it.

3. Height of base station

The higher the height of the base station, the larger the corresponding coverage. The core is that the higher the height of the base station, the greater the gain and the smaller the loss. This is why the macro base stations around us are built so high

4. Height of mobile phone

Customers often complain that they can't hear the signal downstairs. They need to climb upstairs to hear the signal clearly. In fact, it's the same truth. The higher the height of the mobile phone, the fewer obstacles the corresponding signal will pass through and the smaller the loss.

Therefore, if you have to give a coverage range, you can refer to the typical value of coverage distance. The coverage radius of 5g base station is about 100-300m.
