Rebirth My boss is too rich!

The next day, Su Zhe stayed at his hometown. He did not go to Tang Mo, but began to study the 2G GSM network architecture.

He is ready to transform theory into practice.

This is also his top priority for the next month.

In fact, Alipay, stores, Dianka, Taobao, etc. are all being done by people. Su Zhe only needs to be responsible for the overall operation route; but only for the architecture and research and development of the 2G network, he must complete the preliminary work alone.

Because this is the reward of the system!

Su Zhe obviously would not share this kind of thing with others.

As for all the principles of this 2G, the system transferred almost all knowledge points into Su Zhe’s mind, just like experience, which was as magical as a chip implant.

In other words, his current understanding of 2G second-generation mobile communications is absolutely master-level.

“The GSM network is actually similar to radiating wired networks to every corner of the world through wireless networks!”

This may be a bit difficult to understand.

But in fact, this sentence has been compiled by Su Zhe. It is the easiest for people to understand the working principle of 2G network.

For those born in 1999, it may be difficult to understand.

Because routers and wireless The Internet is not yet popular, and is even… only used in some universities and large companies in the United States.

But in 2020, if you ask anyone on the street what a wireless network is, they will tell you – wifi!

Yes, It’s wifi!

In fact, the 2G network can be seen as a huge wifi network.

The mobile base station is the huge signal tower, which is the wifi transmitter. It is responsible for transmitting a signal to all mobile phone users in the area. A network that receives signals.

In other words, a signal tower base station can be regarded as a huge router.

But the complexity of this router is countless times more complicated than an ordinary home router. An ordinary home router is actually just a Gateways transmit data based on IP addresses; base stations require countless gateways, controllers, transceivers, etc.

But right now, Su Zhe only needs to build a simple base station.

Small base stations are based on routers On the Internet, make some modifications to transmit the computer network, that is, the bandwidth network, so that mobile devices can receive it.

This first step of the 2G network is considered a success.

It sounds simple, but in fact… it is that simple.

It’s a base station with modified routing!

Bang!

Su Zhe took out a Cisco GS purchased in the United States. This machine can be regarded as the world’s first wireless transmitting router. It is also a symbol of the rise of Cisco.

Now Cisco The market value of Nass is as high as 590 billion U.S. dollars. It is a giant second only to Microsoft. It is definitely world-class in the fields of routers, firewalls, network cards, etc.

What about NETGEAR and PULNET?-LINK、Mercury and others are all younger brothers to him.

Although Cisco almost went bankrupt in later generations, the company’s current position in the field of Internet hardware is definitely at the big brother level. Several of its certifications are still used around the world until 220.

“I jus

t didn’t expect that the world’s first router would actually look like this?”

Su Zhe looked at the rather complicated big thing in his hand. It was like a small microwave oven, square and square.

What he had to do was to take out the machine, connect it to the network at home, and then radiate radiation that would allow anyone to A mobile network where all mobile devices are connected to the Internet.

This kind of network is of course not the wireless network of later generations, but a mobile band network.

Many networks have frequency bands. Su Zhe only needs to modify it, and the computer may not be able to connect. Of course… right now Many laptops do not have wifi at all!

Because it is not popular yet.

So Su Zhe built a small base station, and there is no risk of network theft.

Once the base station is built, 2G will basically be solved.

The principle is the same Yes, it’s just that Su Zhe’s base station is for his own use; while the 2G network is for the whole world.

Crack!

Su Zhe quickly disassembled the Cisco router in his hand and removed it from a big bag next to it. Here, I took out countless parts, which were all bought in Shenzhen Huaqiangbei and in the United States. They were not big items, but they were quite practical.

Infinite receiver and receiver!

This is to generate and modulate radio frequency current and transmit radio waves. The equipment that is emitted. It is composed of oscillation, modulation and power amplification.

Needless to say, the antenna.

The signal processing equipment, which processes the signal strength… Of course, the real base station also requires cell controller and voice channel control. transmitter, signaling channel controller, etc., but Su Zhe omitted them all.

These things will not be used until large-scale base stations are built in the future.

Small base stations only need to transmit wireless signals to indicate success.

Finally, it is a modem , that is, the”cat” thing, can translate the digital signal of the server into an analog signal that can be transmitted along an ordinary telephone line, and these analog signals can be received by another modem at the other end of the line and translated into a computer-readable language that everyone understands.

This is for the telephone network. Su Zhe wants to change it to a special”cat” for mobile phones.”！

……

In the bedroom, Su Zhe was busy renovating it.

As long as this small base station is completed, he will have reason to convince the Qinghua school to build a real base station at Qinghua school. By then, all students in Qinghua will be able to accept the convenience of mobile networks.

This is the second step Su Zhe needs to take!

If this step is successful, then the next 2G announcement will be a matter of course and logical!

The final”Fortune” forum is when Su Zhe actually launches the 2G mobile network. He will build a large base station in Shanghai in advance so that everyone attending the meeting can appreciate the magic of mobile networks.

That’s why the current small base station is so important… Its success will affect all Su Zhe’s future layouts.
