Chapter 708 Visible Light Communication and Zigbee Network Upgrade

In the field of scientific research on the parent star,'quantum computer theory' is not a secret. What is valuable is the application of quantum states, quantum entanglement technology, and numerous quantum tunneling experimental data.

Nine Institutes got these and returned to the Beijing Aerospace Department to retreat.

Ge Xiaotian brought Dao eleven and others back to Dongshan.

……………

On the flight to Qinggang.

"Sir, what to drink?"

"Oh, the girl is so beautiful."

"Thank you."

"Are there any codes for polar natural ice and ice town."

"This... it's winter. I suggest you drink something warm?"

"No code? Then some Nanwa Fruit Orange."

"Sorry sir, how about a coke?"

"Coke? Forget it, let it be cool."

"Ok."

"Sister, do you know why your three major airlines have lost money so much that they are selling iron?"

"..."

"Because it didn't maximize the commercial elements."

Ge Xiaotian took the water glass handed by the stewardess, "It looks tall, but in essence it is a ticket-selling business, like this airplane shell, sprayed with XBA basketball stars, or Sancha Cup football stars holding high code advertisements, and occasionally giving the ball. The team issued another batch of free air tickets, which not only has advertising benefits, but also attracts popularity. And on the back of this seat, there is no Qingshan Traditional Chinese Medicine Hospital, or the words Zijinhua, Fuwa, Infertility, Quick-acting Jiuxin Pill, I It feels like you have no business minds. Especially this blanket, what a good advertising space, hot springs, hotels, Dabaojian, Mamasang...

"..."

Dao eleven, who was sitting next to him, couldn't stand it anymore, "Boss, you can sleep."

"Sister, remember, go back and tell your chairman, if you don’t follow what I said, you will have to lose next year. In 2002, your superiors decided to open up the private aviation sector. If you are acquired by me, what a beautiful girl, wearing black silk? Moving bricks will definitely look great."

"..."

Dao Eleven waved his hand secretly and signaled the stewardess to go busy, "Boss, what should we do about the network upgrade?"

"This time I communicated with the nine institutes. The biggest benefit is not to send out quantum computer theory, nor to get visible light communication technology, but to activate the receiver that integrates Zigbee technology and visible light communication."

Longtian Zigbee technology is not backward, but too much sharing, resulting in too slow network speed, if the sharing is adjusted to exclusive, 30M network speed, it can be used to the 5G era.

But network speed is network speed, bandwidth is bandwidth, and delay is delay. They should not be confused.

Make an analogy.

It takes 10 seconds to fill a ten cubic water tank, and the speed is: 1 cubic s, which is the network speed.

Bandwidth is how many cubic meters of water can pass through the pipe per second.

The delay is...

After laying the water pipe, you need to notify the pump administrator to start, and the administrator receives a message that the well water flows into the tank. How long is the delay at this stage.

The farther the water tank is from the pump, the longer the water pipe, or there is a message relay station, the higher the delay.

In addition, consider the response time of the administrator, and whether the water outlet at the end of the water pipe is smooth, that is, whether the computer or server has a virus, and whether the hardware performance is excellent.

If a car suddenly squeezes the water pipe halfway, it is called the network cable being pulled out...

Of course, this is just a metaphor.

What's more, optical fibers with the same bandwidth and different materials can withstand different optical powers.

Just like the water flow speed in a water pipe, the material is good, and the water pressure is strong, and the flow rate is fast; if the material is poor, the water pressure exceeds the limit, the pipe will burst, or the water pressure is not strong, and the water is soft...

After listening to these, Dao Eleven, the main research material, was thoughtful, "Integrate ZigBee, complement each other, arrange two communication modes according to the environment, and gradually update SG equipment and only one card."

"Correct!"

Ge Xiaotian took out SGpad and found a set of data, "Just like Tiancheng Square in Jishi, the passenger flow is 50,000 person-times on weekdays and 100,000 person-times during holidays. One optical fiber serves 100 people. There are 1,000 optical fibers and 1,000 A base station, how? It looks like a lot, but for a CBD with an area of ​​200,000 square meters and a construction area of ​​800,000 square meters, it’s too small. Why do you have to pull 10,000 optical fibers or rely on cables to set up super Base station."

"Increase the number of optical fibers and cables, and change the number of shared by 100 people to 10 or five people."

"Yes, I used to worry about too many base stations and parameter microwave interference. Now, with visible light communication technology, such as shopping malls, supermarkets, home appliance stores, furniture stores, especially underground pedestrian streets with poor signals, underground parking lots, etc. The bee was changed to visible light, and the extra Zigbee base station was moved outdoors."

"That said, we don't need to improve the fiber. Even if we continue the old fiber, it can solve the network speed problem."

"Definitely, it would be better to produce dozens of laps around the mother star with excessive production capacity. When the price comes down, the cost will come down. Then it can be connected to various villages to replace telephone lines."

As early as when communicating with Jiu Institute, Ge Xiaotian wanted to understand.

There are many places where China is unable to access the Internet. Instead of competing with North America for Internet speed, it is better to continue to expand the SG series market.

Moreover, as long as the number of fibers is up, Zigbee sharing becomes exclusive, and the download speed can reach 30M.

3G download speed is only 2M, even 4G download speed will not exceed 10M.

We can still maintain the lead.

When the new optical fiber is popularized, it can be upgraded by another gear.

Unless the other party launches 5G, or... more than six thousand satellites are launched.

"Hey?"

Ge Xiaotian blinked, "How many spies remain?"

"More than thirty."

"Let them spread the news, it is said that Long Tian has researched out 20 stars with one arrow and plans to secretly start the network star chain project. By the way, the star chain technology is also handed over to the spies."

"It's better to instigate a few agents. After some agents were arrested, North America has not found out. Exchange this information for grades to help them get promoted and raise their salary... It will definitely be of great use in the future."

"Double agent? It's to my liking! By the way, let Lao Wang hold a press conference and put forward the idea of ​​a "pillar of light falling from the sky", which proves that Long Tian really wants to engage in a network star chain to stimulate and stimulate the science and technology alliance. If you decide to invest in the network star chain every day, it will be a lot of fun."

"But once they do it, we will fall behind."

"Are you stupid? There are more than 6,000 satellites, and the lifetime of a single satellite is calculated according to the highest ten years. If there is another round after ten years, who can handle it? Graphene technology must be used to increase it to twenty years or even more. For a long time, but the question is, do they have graphene?"

"Sell them secretly first, and then raise the price?"

"you are so bad!"

"..."

"The biggest problem now is how to reduce the delay using old fiber."

"Didn't you say, integrate visible light communication into laser guidance and set up a separate communication channel."

"Did I say it?"

"What you told Jiu."

"I'm used to blowing, but I didn't think it would really work."

"..."

"What is the current inventory of optical cables and optical fibers?"

"Weihua and China Mobile are developing business in Xishan, Shaanxi, Heilong, Beihe and other places. The demand is so great that the workshop has never stopped."

"First draw up a batch of inventory, complete the Dongshan industrial chain, and upgrade the Zigbee network to withstand the impact of 3G."

"understand."

"Visible light communication...Bigger is full. When I look back, I will get a batch of LED lamp beads, as well as laser lights and laser lights, and replace all the base stations in our office and Longtian Building."

"Okay, by the way, boss, there are still two days on New Year's Day, do you want to have an event?"

"Forget it, I always show my face. It's not good to be too high-profile. In this way, I can use my elf to make a small video and send a few hundred million red envelopes to the people of the country.

"..."

…………………………

December 29.

Ge Xiaotian rushed to Qinggang overnight.

Tiancheng Electric Industry Group is relatively scattered, partly located in Jishi, partly in Dongshan 15th City, and partly in Dongjiawan Shipyard. After its establishment, its headquarters is located in Zao City.

But in terms of scale, Dongjiawan Shipyard is the largest, occupying almost the entire bay, stretching from the northeast to Golden Beach and southwest to Zhaoshi.

The docks are densely covered along the way, and at a glance, there are all berths.

On the central coast, there are many tower cranes, gantry cranes, conveyor belts, transport vehicles, docks, and floating docks, filling nearly a hundred miles of blank space.

In the future, warehousing, logistics, auto repair, apron...

In the wilderness in the distance, the lights are brightly lit, and countless super large workshops are covered with the earth, which are for the'Tiancheng Electric Industry'.

Here is China's largest precision instrument manufacturing plant.

Here is a heavy equipment manufacturing plant with the most complete Chinese style.

Here are China's largest types of electrical equipment manufacturing plants.

Here is China's most advanced technology for on-the-job employees' further education system.

There are also two legions, two fleets, plus Tiancheng Oil Conservation Brigade garrisoned.

Including Dongjiawan's northeast and southwest directions, the number of guide egg silos is unknown.

After Ge Xiaotian arrived, he didn't make a stop, but found a deep-sea town center docked by the sea, and exchanged for electronic components that integrate Zigbee technology and visible light communication technology, also known as lifi.

Then the lifi equipment will be installed and connected to the Dongshan Tiancheng 10G LAN, which is the mother body of the Shiguang machine that constantly absorbs Internet information.

Unlike the Internet, it is limited to Tiancheng's internal use, and the network speed is...10G, 9Gs.

Well, this is military grade.

The scientific researchers got the signal receiver, worked overtime, made new parts, and installed lifi driving computer, photosensitive sensor, stabilized gyroscope, satellite receiving antenna, loaded laser guidance for the huge mechanical leg...

December 30.

early morning.

Ge Xiaotian got into the crotch of the two legs again, put on the'trousers' connected by laser, fixed the waist and abdomen, put on the helmet and put down the goggles.

"Go!"

Kang Dang, Kang Dang...

"start running……"

, ,...

"Success!"

Seeing this scene, the researchers who had been studying for two years threw away their wrenches, screwdrivers and other tools in excitement and cheered.

"No, no, there is still a delay, about 1 second, we need to continue to improve. Moreover, the upper body is still missing."

Ge Xiaotian stretched his right foot forward, bent his left foot, and braked urgently while moving at high speed. The superalloy metal feet fused with graphene rubbed against the concrete floor, sparking lightning all the way...

"Study the upper body, a double-bucket clamp, a hammer, which can hit, dig, and clamp, and the mining efficiency will definitely double in the future."

"Boss, the big black dragon, do you want to modify it?"

"Dongshan LAN only covers Dongshan."

"The server can be set up separately."

"First complete the whole body. That big guy needs five people to drive, and the material is different from this delicate little thing."

"What about Oolong fighters?"

"The speed is too fast, and there is no corresponding airport. If you fly out of Dongshan, the laser guidance will be disconnected. What if you hit the flowers?"

"..."

"However, for the first experience of mecha, although there are only two legs, it feels...tsk, the feeling of driving a tractor is back!"

Ge Xiaotian looked at his two legs beautifully, "Get me a layer of invisible material, the black one."

"Good boss."

At this time, the way to deal with the shares of Nanyang Development Group came back to life.

"Boss, it's done."

"not bad."

Ge Xiaotian didn't ask about the process, and said: "Take a mention of the stocks and market value over there, and then hold an auction at the sea racetrack, sell off the Nanyang Development Group, and start with 200 billion."

"Sell as soon as we bought it?"

"if not?"

"Li's richest man in Beijing sold 90 billion yuan at a super low price. There must be his reason. If we sell 200 billion yuan, someone will buy it?"

"You have to do everything, otherwise the acquisition of Xiangjiang Huada Investment Group will do a lot."

Ge Xiaotian walked out of the operating workshop, "If we spread the news of our acquisition of Nanyang Development Group, what would developers in Taiwan, Hong Kong, Malaysia, Indonesia and other places think?"

"You want to kill it."

"and then?"

"Fear of the Xingyue Bay industrial chain, group together and fight us together."

"Yes, our influence is so great, what about the Xiangjiang Real Estate stock market?"

"Xingyuewan's industrial chain is taking the people-friendly route, and home buyers will wait and see in all likelihood, but if we do not pass, it will cause Xiangjiang Real Estate to enter the off-season and the stock market will fall."

"Only we know about this. Then, can Xiangjiang Huada Investment Group take the opportunity to buy the bottom?"

"Then, if we sell Nanyang Development Group, buyers who cannot buy Xingyue Bay will focus on other properties that have already reduced prices, which will drive housing prices and the stock market up, and Xiangjiang Huada Investment Group will sell again."

"This is just one operation."

"I see, this is called capital operation."

"It can be repeated several times."

"..."

There was a moment of silence, "Didn't you say, don't you be Soros?"

"Yes, I am Ge Xiaotian."

"..."

"Of course, what I pit is only Nanyang developers, let the common people buy real estate at a low price, and then it can appreciate immediately, is this a good thing?"

"We might as well take the opportunity to incorporate Nanyang Development Group and change it to Nanyang Tiancheng."

"After the Southeast Asian economic crisis, in a short period of time, there is no commercial value. If you build a building, you can earn one-tenth at most. Instead of working hard, we should concentrate on pushing domestically. Besides, our goal is Xiangjiang. After the operation, the Xiangjiang Huada Investment Group was changed to Xiangjiang Tianrong. Together with Chen Feng’s Shangpin International and overseas amusement projects, we also have a firm foothold there."

"The boss is foresight."

"In this way, there are Qinggang, Magic Capital, Jianfu, and Xiangjiang along the coast, and Dongshan, Nanhe, Xishan, Beihe, Shandi, and deserts inland."

"Making dumplings, all in one go, take the Jiangnan, Jiangbei, Southern Capital, Liangguang, Nanyun and other places to dominate China Real Estate... the boss is domineering!"

"Ha ha."

Ge Xiaotian was a little bit complacent, "As the saying goes, the soldiers and horses are not moving, the food and grass go first. Now the important thing is the transition. Waiting for Brother Hao, Shuai Bo, and eldest brothers to join together, then everyone will join forces in Jiangbei..."

"Shoot a battle across the river?"

"good idea!"

…………………………………

'Dip, the network is being upgraded...'

Early morning on New Year's Day.

It is rare for people who have a day of vacation and do not hide in the blankets to sleep in. After getting up early, they find that the smart card that stays all the time has failed.

I can’t see the community mission, I can’t open the door of the community, I can’t buy anything, and I can’t take the bus. Even if I want to find a community shared bicycle, I have to give up because I can’t unlock it...

and.

Because the community display screen cannot receive the network, it has become a bar.

The same is true for advertising screens, projection lamps, various LEDs...

At this moment, the whole world seems to have changed.

People who originally wanted to do something are suddenly a little confused and at a loss...

"Play chess?"

"It's weird. I used to practice morning exercises and play chess. I didn't even notice whether I brought the smart card or not. Even if I put it at home, I always thought of turning my head back. Now, I'm right in front of me, but I feel empty in my heart. ."

"No internet connection."

"Have you complained?"

"There is no internet connection and the customer service network phone cannot be dialed. How can I complain?"

"Fixed."

"The monthly rent for that thing is so expensive, my house has withdrawn early."

"..."

Hu Wei walked out of the unit hall, heard the elders chatting, took out the smart card and looked at it, and was surprised to find that the signal was full.

Not only that, the Pokemon, who was asleep because of no internet connection, even raised a red envelope.

Tap slightly...

'Congratulations, open Boss Ge's red envelope and get 68 red notes.'

'With red envelope: only today, 50% off online purchases.'

'With a red envelope: only today, 20% off the movie ticket.'

'With red envelope: only for today, 10% off car purchase.'

'With red envelopes: only today, 30% off in supermarkets.'

'With red envelope: only today, free viewing.'

'With red envelope...'

'With red envelope...'

Wow...

Dozens of prompts flashed past...

"Damn, so much? Wait, the internet seems to be faster."

The voice did not fall.

Wow...

Pokemon suddenly threw out countless daily necessities...

The kitchen knife only costs two bucks, buy one get one watermelon knife...

The pillow only costs two yuan, and you will get two pillow skins when you place the order...

Cotton mopping only needs one piece and two, and the knitted socks will be given as soon as the order is placed...

The spatula is as bloody as 50% off...

Belt...

"..."

Hu Wei took a closer look at the rapidly beating real-time internet speed, "Free Zigbee, sincerely do not deceive me!"

…………………………

"Boss, since the morning, there have been many customer feedbacks requesting that Zigbee Network be changed to a charging mode."

"Why charge, isn't it good to be free?"

"The number of feedbacks has accounted for 50% of the total users, and it continues to rise, especially the parents of children who have begun to complain about Tianwei..."

"Popular opinion is embarrassing!"
