Building madman

January 1, 2002, ten o'clock in the morning.

The upgrade of the Zigbee network is over, and the stagnant and silent world seems to come alive.

In communities, squares, and streets, countless display devices are instantly filled with colors.

Public welfare videos, commercial advertisements, decorative images, gorgeous projections...

Accompanied by BGM with different styles, it outlines the prosperity that a gorgeous metropolis should have.

only……

"Grass, don't you need money for this ad?"

"Grab a red envelope. I have listened to the promotion for five minutes. The ghost knows how many I can remember."

"This is not called advertising!"

"What's that called?"

"Ad bombing!"

"..."

"Hey, I heard no, hundreds of thousands of users jointly reported the online shopping system to the Supreme Administration of Industrial Information."

"I'm going, what hate?"

"The activity is too strong, I can't stop it when I buy it softly. In the end... the savings are spent before I react."

"..."

"Also, Tiancheng Chamber of Commerce puts too many advertisements, which seriously disrupted the market order. The leader of industrial information asked Ge Lao Er for tea."

"Will Zigbee Network be blocked?"

"The possibility is unlikely. It is estimated that the fee model will be opened according to the questionnaire, increase revenue, reduce advertising volume, and balance losses."

"Charge? Traffic is expensive."

"Yeah, I don't know if I can afford it in the future."

"By the way, what did you choose?"

"It's free, fools will choose to charge."

"what about you?"

"It's definitely free."

"Then who chose to charge?"

"The ghost knows..."

Zigbee Network is different from the wireless router that was born in 1998 and developed slowly in North America. It was eventually acquired by Huo Dun’s wireless router from Xuezang. It is also different from the traffic packets of 2G and 3G modes provided by communication operators. Satellite network, SG server and international network, construct a'semi-shared' network service.

The reason for bringing a half-character is because the user must use SG equipment and smart card.

In fact, if the Zigbee network is disconnected from the international network, that is, the Internet, it can still operate.

This involves knowledge of local area networks, metropolitan area networks, and wide area networks.

Make an analogy.

Jishi Tianheng Automobile Trade Group builds an enterprise local area network so that its employees can freely access the data stored in the enterprise server.

One day, Jishi Tianheng employees want to access the Jishi Tiancheng real estate server, so the two companies must install a switch to exchange data between the two enterprise servers.

In the same way, Jishi Tianrong, Jishi Tianwei, Jishi Longtian Technology, Jishi Sun Paper, Jishi Wanshi Technology, etc., have also joined.

There are more people, more companies, and more data, but the servers are too scattered and there are too many switches, which seriously affects the speed of data exchange.

Boss Ge decided to increase investment, install Shiguangji servers, set up a'three-layer switch' to speed up internal data exchange, and open up permissions to promote this'local area network' to Jishi, so that the masses can also participate.

Thus, this is the metropolitan area network.

One day, the people in Jishi wanted to learn about Zaoshi New Town, but found that there was no information about the other party on the Internet.

Boss Ge immediately patted the table: connecting the Jishi Metropolitan Area Network and the Zaoshi Metropolitan Area Network.

The city and the city are the same, so the "Internet" was born.

The information that occurs every day in the two cities is transmitted to their own servers through optical fibers, or to a large shared server, and then to every user who visits, thus creating the information age.

Of course, both online users and corporate websites need to have their own access address and user name to avoid logical differences and cause network crashes.

So the question is, what is the difference between Zigbee Network and traditional Internet?

fast!

quickly!

This fast is not a comparison of the future, but the present.

The download speed of the mobile terminal is 300K, far exceeding the 20K of the 2G network, and the download speed of the Internet cafe is 2M, far exceeding the 50K of the telephone line mode.

In addition, SG equipment adopts the manufacturing method of integrating information into the equipment, such as large-scale 3D game Shenlong comprehension, fast file reading, fast network data exchange, and reduced delay, which brings smooth operation like a cloud.

Pokemon, online shopping platforms, advertising, etc., are also the same reason.

Of course, the low latency of the Zigbee network is only relative to commercial operations, and it is still too high for industry and military.

However, with the network upgrade, the delay problem has been greatly improved.

In summary, it is not difficult to see that the Zigbee network system was developed from the Tiancheng LAN, and the external connection is completed by the Shiguang machine of the Tiancheng Aerospace Department that constantly absorbs external information.

As for switches, optical fibers, optical cables, base stations, etc., they are all handed over to Weihua, who is authorized by SG equipment, which is equivalent to project exchange.

Therefore, the Zigbee network is owned by God.

Zigbee replaces telephone communication services. In addition to cooperating with Tiancheng to provide new mobile 2G cellular data networks and digital mobile office services, several other communication operators have already withdrawn from Dongshan.

As Tiancheng marched into Nanhe, Xishan, Beihe and other places, some leaders were not happy.

Calls are charged by the minute, so who is willing to take such a big cake by Tiancheng's free internet?

Therefore, the big leader of industrial information really invites someone to drink tea.

After all, Tiancheng has no communication authorization and no relevant license.

For Ge Xiaotian, this is not a crisis.

One is that there is another Shiguangji server on the Nine Institute, which is a large database, and information security is not a problem.

The second is that Zigbee popularizes the industrial field, and the big leader of industrial information cannot just care about information and ignore industry.

The third is that the Ninth Institute has produced visible light communication technology, which means that the military will also use Zigbee.

Therefore, what Ge Xiaotian considered was whether he could drink the'benefits' of this tea.

Zigbee Network has always adopted a free model, but it is not without revenue. On the contrary, it is more profitable than the fee model.

With the popularization of SG equipment and smart all-in-one cards, unlimited traffic, leading to a trend of Internet access for all people, the three brands of'high, middle and low' in the online shopping system can easily enter the public's view.

The value contained in this can no longer be measured by money. At least millions of shops, large and small, can be exchanged for N Zigbee network systems based on the annual advertising fee and profit paid by the online shopping platform traffic.

But after two years, the brand was built, and people have begun to get tired of advertising bombing, which is bound to adjust the operating model.

Qinggang.

International Tourism City, Gold East Coast.

The twelve large characters written by Vice Dong's hand were driven by twelve rainbow hot air balloons across the golden sand beach, beautiful and shocking.

Although the rear villa area has not yet been completed, supporting facilities matching the beach culture have been laid on the coast.

Lighthouses, stone sails, wooden boats, ancient ships, beach huts magnified by N times, rows of marine sculptures...

As an important project of the same level as Jishi Canal Development Zone, Zaoshi New City, Jinxiuchuan University Town, Neoblas, the future magic capital Wuzhou Avenue, and Xiangjiang Sea Racecourse, there are five cement boats and one A small real aircraft, a marquee-style ground-effect aircraft landmark, and the underwater world that may be built in the future...

Ge Xiaotian took the tua to the airport, while enjoying the scenery along the way, thinking about the new mode of Zigbee network again and again.

Fees on time, monthly traffic, exclusive membership, VIP acceleration, personalized recommendation...

"If you make these, will you be struck by lightning?"

"Boss, here it is."

"Ok."

Ge Xiaotian walked off the tua and looked around in a wild thought. He was stunned to find that all the flights that stopped at the airport had not been here for a few days and all had been painted.

'Brain and kidney fluid!'

This is not important. The important thing is that the person holding the small brown bottle with a straw in his mouth looks exactly like him.
