What kinds of mobile communication base stations have you seen?

I believe you can often see all kinds of mobile communication base stations on the roof or roadside. Some are directly installed with antenna poles, some are communication poles, and some are large iron frames covered with antennas. Besides these, are there other types of base stations? Today, Bian Xiao will show you the common base station antennas in life.

Base station definition

A mobile communication base station refers to a base station that sends wireless signals through radio waves. The base station plays a very important role in the mobile communication network and is an important part of the mobile communication system. At present, the mobile communication system consists of core switching network subsystem (NSS), radio base station subsystem (BSS) and mobile terminal (MS). A radio base station subsystem (BSS) usually consists of a base station (BTS) that receives and sends radio signals and a base station controller (BSC) that is connected to one side of a switch. We often say that the base station belongs to BTS, and the simple structure can refer to the following figure:

Part of the base station BTS

The base station BTS is composed of radio frequency transmitting and receiving equipment and antenna feed system, which is equivalent to a radio demodulator and is responsible for transmitting and receiving signals. Generally, multiple base stations BTS can form a cellular system, and send and receive signals to each other through the base station controller BSC, thus completing the expansion of mobile communication signals. Our common antenna belongs to the antenna feed system of a base station. The equipment is installed in the computer room of 10 square meters and connected with the antenna through the RF coaxial line.

Base station antennas are generally installed at a height of 20-60 meters, and then cover floors and street areas downward. In first-and second-tier cities, floors in most areas are relatively high, and direct installation on the roof will also have an impact on the appearance of the building. In addition, the directly exposed antenna will also give people a psychological shadow of radiation, so the three major operators are trying their best to develop various beautification antennas. In addition to the common base station antennas, let's take a look at what types of beautification antennas are available:

1, beautify the exhaust pipe antenna. This antenna is like a PVC exhaust pipe. Its height is 3-4 meters, but its diameter is larger than that of ordinary sewer pipes. Generally installed in the four corners of the roof. According to the installation method of operators, there are generally more than three (according to the statistics of one operator). Another obvious feature is that there will be several feeders under the exhaust pipe. Beautify hidden effect: 4 stars

Beautify square column antenna. This antenna is a square column about 600*600*(3/4/5 meters high). It has various colors according to the owner's requirements, usually white. The obvious feature is that there will be several feeders under the square column. Beautify hidden effect: 3 stars

Beautify the antenna of the air conditioner cover. This kind of antenna is generally installed on the outer wall of the roof or wall, which is larger than that of ordinary air conditioners. 1 The antenna size of the beautified air conditioner cover is equivalent to that of two ordinary air conditioners. Because the shape is consistent with ordinary air conditioners, it is difficult to be found. Beautify hidden effect: 4 stars

Beautify the antenna of water tower. Nowadays, more and more families use solar energy, and solar energy systems usually install a water tower on the floor. Operators also follow this approach, installing water tower-shaped antennas on the roof. The obvious feature is that the water tower will be relatively high, generally more than 6 meters high, and the feeder will go down to the computer room along the iron frame.

Beautify tree antenna. This type of antenna is generally easy to find, mostly installed in tourist attractions and parks with trees, but several antennas on the trees are still obvious. In addition, the height of the base station is 30-50 meters, which is higher than the surrounding trees. Beautify hidden effect: 2 stars

Beautify spotlight antenna. This is a small beautification antenna installed on the balcony or roof of residential buildings, which is mainly used for deep coverage of residential buildings. The obvious feature is that there is no light inside the spotlight antenna, and its outside is a layer of white plastic material, while ordinary spotlights are transparent glass. In addition, the feeder will be thicker than ordinary cables. But because the antenna is small, it is difficult to find it downstairs. Beautify hidden effect: 4 stars

In addition to the normal exposed antennas and the above-mentioned common beautification antennas, operators also have antennas in other special scenes according to the requirements of different places and properties, with the main purpose of achieving a beautification effect and reducing the public's dislike of operators' antennas. In fact, the inside is the same as the ordinary antenna, except that a different shell is added outside. It should be noted that the location of the operator's base station will only be built after the owner's permission and signing the relevant lease contract, and it is also approved by the relevant industry and information departments and protected by law.

According to the criminal law of our country, the crime of destroying radio and television facilities and public telecommunication facilities refers to the act of deliberately destroying radio and television facilities and public telecommunication facilities in use and endangering public safety. Be sentenced to fixed-term imprisonment of not less than three years but not more than seven years; If serious consequences are caused, he shall be sentenced to fixed-term imprisonment of not less than seven years. Whoever negligently commits the crime mentioned in the preceding paragraph shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years; If the circumstances are minor, they shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention.

Therefore, in the face of antenna disputes of operators, we should communicate with relevant departments and operators by legal and reasonable means, and have the right to ask operators to provide radiation test safety reports to safeguard their own rights and interests.
