C1332 The Switch of the Base Station

Mobile communications, communications with fixed phone networks, then he would need a Base Station, the function of this Base Station. It's to provide a certain amount of radio coverage, through the mobile communication center. A radio receiver to transmit messages with a mobile phone terminal.

It could be said that the set of equipment Qin Guan brought in in the hotel was a miniature Base Station, and the most common Base Station was the mobile signal transmitter tower outside.

One. The complete Base Station receiver included wireless transmission / receiver, antenna, and all signal processing parts that were unique to all wireless interfaces. The Base Station receiver could be used as a wireless mediator, responsible for receiving and sending signals.

However, any Base Station could cover a certain area. For example, Qin Guan's small-scale Base Station only had a range of five kilometers.

A large Base Station also had a limited range. This way, once it was out of the Base Station's range, a mobile phone would not be able to communicate.

At this time, they would need to form a network, which was within a region. The multiple Base Station and the receiver formed a honeycomb network. Through the control of the signal between the receiver and receiver, they could transmit and receive the signal to reach the transmission of the mobile signal. The region within this region is also the coverage of the network that we often talk about.

Because this type of transmission is very similar to a beehive, it is also called a honeycomb mobile phone network.

This type of transmission is similar to a honeycomb mobile phone network. The network coverage was very extensive, and it could be used to increase the coverage of blind spots.

When the person holding the mobile phone moved, it would involve another problem. The signal he started transmitting in Base Station followed by the signal. The signal was transmitted from another Base Station. When he was moving back and forth between the two Base Station, this signal could not be cut off, or else the quality of the communication would decrease.

The two of them held their phones and made a call. What if the most crucial moment was when the Base Station switched, and they missed it?

For mobile communication, the ability to switch between Base Station was the most important.

There was only a portable and beautiful mobile phone, which was only one of the steps. How to provide high-quality communication was the thing that could move the consumers the most.

Now, Qin Guan had mentioned this aspect, which stunned Carl.

"President Qin, I don't understand what you mean." Carl said.

Don't understand? Qin Guan had a smile on his face. "General Manager Carl, I mean, if you want to test the quality of our system, he said. At least we need to set up a sufficient amount of Base Station in a city. We need to set up a network in order to truly detect it. You want to use this set of equipment to test it. It's not scientific. It's impossible to determine whether it's good or bad."

But that way, the price would be too high! Carl thought to himself. Borrowing this set of equipment... Flower! No! It's over! How much? However, if they were to set up a network in the entire city... That would cost a lot, and it wasn't something that an ordinary company could afford!

Was it worth it to pay so much for such a huge price? He would probably have to invest all the liquid funds in the company.

Carl began to hesitate.

"I knew you wouldn't understand." Qin Guan said, "You are really an amateur in this aspect, but I don't blame you. Other than us, no one else has realized this problem. The Motorola company's handphone has never considered this problem. "

Upon hearing Qin Guan's words, Carl was delighted. He had found a way to defeat Soro!

Carl really trusted Qin Guan's mobile phone. The fact that he could tell ___ about all these technical problems was enough to show that his company's research was very deep. At the same time, his explanation was also reasonable and reasonable. This switching problem should be the most crucial.

Since the Motorola company had never considered it on their mobile phone, it seemed that this was definitely not possible. In the future, when they compared it with the Motorola company, it would have a crushing effect. That's right, that's it!

Carl was very pleased with himself when he thought of this. However, when he thought about Qin Guan saying that he would form a network in the entire city, he was afraid that the cost would be astronomical!

Actually, it was still manageable now. After all, the public did not feel much about the so-called radiation. In the later generations, everyone's expressions changed when they talked about radiation. If they set up an antenna in Base Station at their doorstep, perhaps countless people who were bored and had nothing to do would start to protest.

As long as someone encouraged them, they would protest. Their goal was also very clear. They wanted to let the Base Station leave. They were afraid of getting radiation, but when the Base Station moved away, they would protest that their phone signal was bad.

Now, no one had this idea.

"President Qin, if we set up a network of about 100 kilometers on our intercontinental highway, how many Base Station would we need?" Carl asked Qin Guan.

In the urban area, every inch of land was worth a lot of money. Finding a place to set up an antenna required approval. The procedures were cumbersome. In comparison, it would be much easier to find a place on the intercontinental highway.

Furthermore, that place required mobile phones the most because there were no phones there at all!

Hearing the other party's proposal, Qin Guan also nodded. Indeed, he was the general manager of a communications company. His brain was extremely flexible and he thought of a solution so quickly.

Originally, Qin Guan suppressed it like this because he wanted to directly develop the system in their capital. This way, they would definitely form a network in the country and use their own system in the future. When they leveled up in the future, they would also need help from their own system. That was all. They will completely occupy their market and no one else will be able to interfere.1

But now, the other side had thought of the intercontinental highway. Since that was the case, they might as well agree.

"That's fine." Qin Guan said, "If it's a hundred kilometers, at least five."

One. How far could the Base Station cover? It was a general problem. In the cities in the future, it was rare to see tall iron towers moving the Base Station, because most of the Base Station had become a residential area.

In the urban area, due to the large volume of conversations, there were many cities in the Base Station. In order to prevent interference between the Base Station and the problem of a single Base Station's capacity being saturated, the range of the design was about 100-200 meters, and many of them were directly installed with signal amplifiers in the corridors. (Take a look at the corridors in your own home, and see if there's anything like a mushroom head. That's it. )

In the suburbs, since the volume of conversations was relatively small, a single Base Station covered a longer distance. Generally, it could cover a radius of about 3 kilometers. As for those large iron towers in the Base Station, theoretically, a GSM Base Station could cover 35 kilometers.

Setting up five of them was enough to satisfy the needs.
