Questions about mobile base stations Yes me, and correct I also give extra points

It is an insulating tape, which can generally be bought at the hardware point.

But you have to buy it at a regular store! The quality there is guaranteed.

If the insulating tape is used improperly, it will produce leakage, endanger personal safety or cause disasters. Nowadays, there are many kinds of insulating tapes, such as power-off and electrical insulating tapes.

There are also thermally conductive insulating tapes.

Insulating tape hardware points can be bought.

Of course, the insulating tape will soften when exposed to heat.

The current quality is generally not very good, and some parallel goods are still very dangerous.

But just buy it at a more regular store.

That's all, do you understand!! 1

Self-adhesive tape, there should be one there that sells electrician's supplies, but it seems that the quality is not as good as others.

The base station is not filled with insulating tape

That thing is mainly anti-high-pressure

Just ask at a place that sells electricians

There are cheap ones and expensive ones

The 3M in the United States is generally used on base stations, but it is quite expensive

The CDU you are talking about should be a combiner unit, and the TRU is a carrier-frequency unit. Is the base station you go to Huawei's BTS equipment? The name of the equipment is different for each manufacturer.

Mobile base stations are generally referred to as BTS. The equipment inside includes high-frequency switching power supply, BTSE equipment, digital distribution frame DDF (some transmission equipment is installed on the digital distribution frame), optical fiber distribution frame ODF, etc.

Now it is very difficult for mobile companies to build base stations in residential areas, haven't you read the reports? In order to build a base station in the community, the mobile company did not hesitate to spend a lot of money to disguise the base station antenna as a big tree. You agree with that!

It's not that I'm criticizing you, the sense of self-protection is too poor. This is a long-term hazard, I stayed in the PHS computer room in the mine for a while and dizzy, they always say that there is no evidence of the harm of wireless radiation to the human body, and it will be too late when there is evidence, why the country's standards in this regard are lower than those of Western countries. The point is that it is easy to install and dismantle, but it is difficult to dismantle, if you stop it yourself, it is a crime of sabotaging national communication equipment, and you can't afford it.

There is another example,Mobile base station radiation caused a family of TV can not watch normally,**Inexplicable noise in the line,This guy knows how to do it,Finally, the mobile company wrapped the wall of his house with a layer of snowflake iron,It is also said to be waterproof。

It must be installed on the roof, the antenna transmission power is quite high, you can't install it in the room. Generally, this kind of small site is installed on the roof of your building, and it has no effect on you, anyway, the antenna should not be facing the room.

Nothing. It's just a signal amplifier.

Fake base station, it is illegal to use fake base station to send fraudulent false information!

Will you fix your phone? : One word is omitted here.

Hello, the mobile base station cannot be built so low, and your downstairs may not be a base station, but a mobile broadband fiber. Rest assured, there is no problem with this, if it is a base station there is radiation, but the base station is built on the roof and other high places, otherwise there is no signal, hehe.

In a cellular mobile communication system, information can be transmitted via fiber optics between all base stations and mobile switching centers.

In a cellular mobile communication system, the signal coverage area is divided into small cells, which are usually hexagonal honeycombs. Each of these zones is assigned multiple frequencies with corresponding base stations. In other zones, duplicate frequencies can be used, but adjacent zones cannot use the same frequencies, which can cause co-channel interference.

Information can be transmitted via fiber optics between all base stations and mobile switching centers.

a、b、c、d

In the Nokia base station, a 2m circuit (coaxial cable) is used from the transmission device to the base station equipment.

The transmission equipment from the base station to the BSC uses a fiber optic connection.

In some places where it is difficult to erect optical fibers, microwaves are used for data transmission.

I haven't seen infrared data transmission, but I've only seen a little information, and there are few applications.
