This requires professionals and professional equipment to test the base station signal. Some phones have this feature, but not all phones. Generally speaking, with the base station as the center, the signal coverage of the base station is within a radius of 500 meters.
-
According to your description: Strictly speaking, the base station coverage can be very large, but due to the limitation of the number of mobile phones that each base station can serve, the base station coverage is determined by the number of mobile phones in this circle, generally 100 meters to 500 meters in the city, and a few kilometers or even dozens of kilometers in the suburbs. This still needs to be tested by professionals.
-
Do you mean to test the cell phone signal with a number of 189? There's really no way to test this. Only find a specialized department.
But with a PHS before, what a signal is like that. It's a lot worse than Unicom. Hehe.
I'm not speaking ill of telecommunications. It is better to be mobile on a mobile phone carrier.
If you really want to test. It's best to find a car and have your own car. Motorcycles are also good. Watch your phone drive around you for a few kilometers to see how your phone signal looks. Generally, the signal is not good in the countryside.

The radiation range of the base station is generally set to the base station power as the benchmark urban area, with more users, heavier than the signal quality, the general power is smaller, the base station is more, and the coverage radius is 500m in the suburbs of the community, with fewer users, heavier than the signal coverage, and the general power is larger, the base station is less, and the coverage radius is about 10 kilometers.
The above is only an approximate value, because if the location of the base station is very critical. You see that the base stations outside are basically built on high hillsides, and that's for his coverage.
At present, the spacing of base stations in dense urban areas is about 200-500, the general urban leakage area is within 1 km, the suburbs are about 1-2 km, the rural areas are generally covered at 3-5 km, and some areas may have a base station at 10 km.
Due to the late construction of 4G base stations, the current coverage is slightly insufficient, which can probably ensure that the coverage density of large and medium-sized cities and suburbs is close to 2 3G base stations, and the coverage of small city centers is acceptable, and the coverage of the rest of the areas is insufficient.
-
What is the coverage radius of a 5G base station? Mobile phone signals, centimeter waves, and the number of base stations in Shenzhen to achieve full coverage of 5G standalone networking.
-
The base station refers to the radio transceiver station that transmits information between the mobile communication exchange center and the mobile terminal in a certain radio coverage area.
China Unicom also sets up base stations at different locations, but the coverage area of the base station is not a fixed value, and the range is not fixed.
-
The coverage area of the wireless digital TV base station is about 40 kilometers, and the signal coverage is very weak, according to 1 kilometer is equal to 2 miles, it is an ordinary 80 miles, 1 mile is equal to 500 meters, you will know that the coverage of wireless digital TV, it happens to be about 80 miles, I hope it can help you.
-
Depending on the type of base station, if the tower type is also divided into two-way or one-way towers, the general urban area is artificially reduced to 5 kilometers, and the maximum regional base station is 40 kilometers or even 43 kilometers (suitable for rural and mountainous areas).
-
The single signal coverage of the mobile base station signal tower is about 500 meters and 2000 meters, and the radiation distance is 50 meters away from the base station, which has no harm to the human body.
-
A transmitter and receiver are required for the mobile phone signal to be turned on, and a modem is also required for the mobile phone, and the range of the base station that transmits the mobile phone signal is within a radius of 15 kilometers. The world is not equal to mobile phone base stations are divided into macro stations, micro stations, repeaters and so onAt present, the coverage of the largest base station in common equipment can reach a radius of 25km and 35km, and special conditions require the use of enhanced extension equipment, which can reach 55km.
-
The coverage of the base station signal is not the same. The height and size of the base station are different. Its coverage is different, and the plains and mountains are not the same, generally covering thousands of meters to tens of kilometers.
-
The signal coverage of the base station is within a radius of 10 km!
-
The signal coverage of the base station varies from a few thousand meters to tens of kilometers.
-
The range varies in size, with a radius of several kilometers to tens of kilometers.
-
2. Frequency and distance; The higher the frequency of the signal, the worse its diffraction ability, the greater the same loss, the farther the distance, and of course, the greater the loss;
3. The transmitting power of the base station; The greater the transmitting power of the base station, the greater its coverage range;
4. The height of the base station; The higher the height of the base station, the greater the corresponding coverage, so that the greater the gain and the smaller the loss;
5. The height of the mobile phone; The higher the height of the mobile phone, the fewer obstacles the corresponding signal has to pass through, and the less its loss;
-
It depends on what base station you are, what type of land, one kind of plain, one kind of mountainous area, and another kind of space space.
-
The coverage radius is about 10 km.

Candidates will not be allowed to enter the examination room when the name of the admission exam is wrong, and the announcement of the registration of the teacher qualification certificate will be clearly announced, and once the information is filled in incorrectly, all the consequences will be borne by themselves. The method is as follows: 1. If the name is wrong, it is not because of the wrong filling in when registering, but because of network factors, directly consult the local education bureau for processing.
2. If it is a mistake, contact the Education Bureau to make changes, 3. Or directly**.
-
It depends on what type of base station it is and what it is used for.
-
The base station signal is a wireless signal and can be measured with a spectrum analyzer with an antenna.
According to the national standard, select the appropriate antenna model, measure the signal power through the spectrum analyzer, if the signal reception is not very good, it is usually caused by the signal power that reaches the test point is too low, at this time, you can apply to the operator to build a base station.
If you have any questions about the use and test of the spectrum analyzer, you can contact me.

It can be distinguished from several aspects:
1. From the number of GPS antennas can be distinguished, moving signal towers.
GPS antennas are generally not installed (now in mobile.
The 3G TD station is equipped with 1 GPS antenna). Some of China Unicom's base stations have CDMA equipment in them, so one GPS antenna is installed on the signal tower. The base station of the telecom has CDMA equipment and is equipped with 3 GPS antennas.
2. From the installation position of the TD antenna (a relatively wide rectangular antenna), you can distinguish between the telecom and the mobile tower, and the signal tower of the telecom generally installs the TD antenna to the upper platform. The TD antenna is generally installed on the lower platform.
3. From the station room of the base station, the station room of Telecom is a blue top with a thin yellow bar in the middle. Unicom is a blue top, and there is no yellow bar in the middle.
4. Look at the antenna of the closer, some towers are hung with three layers of antennas, which are generally the common stations of Unicom Telecom, and the mobile ones are generally one to two floors. There are also Unicom antennas, some of which will be very small, I don't know if it has something to do with lack of money.
Generally, the 4 sections of the mobile pole are 12 meters high, and the 6 sections of Unicom are 18 meters, and the mobile RRU is hung on the pole, and Unicom is hung under the pole; There are 9 lines of mobile 3G antennas, and 6 lines of China Unicom 3 bands; A small cross will be installed in the middle of the moving pole.
For RRU), Unicom does not;
China Unicom generally has three layers of antennas in urban areas, with 900 antennas at the top, 1800 at the middle, and 3G at the bottom. If you watch too much, you will feel that you don't have 3G installed on the move
, up to two layers of antennas; In the countryside, in the wild, the roof computer room is beautiful and bright, and the tiles are mobile, and the house is not good or even the open air or iron cage connection;
Unicom feeder. The wiring walks along the pole, and the mobile is equipped with a wire rack; It is said to be a lightning rod for communication and mobility.
It's all different, observe it for yourself.

Let's talk about the simple method of distinguishing the square year, and the mobile base-chain air station antenna has only two sets of antennas at most, (G900
D1800) has three sectors in a group, (the sector is the wrench in the shape of a giant strip that we can see) sometimes it is a group, sometimes it is two groups, depending on the number of users and traffic in the area, if you only see a set of equipment, 80% of it is a mobile base station: then China Unicom has a maximum of three sets of antennas (G900
D1800 also has a C network 800) a group is also a shed with three sectors, but as long as there are three sets of antennas, it must be Unicom's base station antenna.
Another way to distinguish between is that the first sector that moves is facing due south (there are very few sectors that move and very few sectors are facing due north), and the first sector that is connected is facing due north (and there are very few sectors that are also connected and rarely facing due south).
That is, the direction of the three sectors of the movement is: due south.
Northwest. Northeast.
Connected: due north.
Southwest. Southeast.
Hope it helps.

I can't tell the difference, there must be a sign at the door of the Ji Hong station: or Cong that operator.
Equipment in the computer room: Other operators rent a computer room to cover the location of the group, make use of favorable resources, and save costs, so one computer room has several equipment.
Outside the machine room: Under the feeder, the tower enters the entrance of the machine room, and each feeder is marked with the line of the house.
The antenna is so high that it's hard to see with the naked eye, haha.
-
Hello: It can't be seen through the antenna, but there is a logo of the corresponding operator on each base station, and you can check it through the sign.
