In the field of scientific research on home star, "quantum computer theory" is not a secret. What are precious are the application of quantum states, quantum entanglement technology, and many quantum penetration experimental data.

After receiving these, the Nine Institute returned to the Beijing Aviation and Pacific Department for retreat.

Ge Xiaotian took Dao Eleven and others back to Dongshan.

…………………

On a flight to Qinggang.

"Sir, what to drink?"

"Wow, the girl is so beautiful."

"Thanks."

"Is there any polar natural ice, iced ode?"

"This...it's winter now, I suggest you drink some warm?"

"No ode? Then come some Nanwa fruit oranges."

"Sorry, why don't you come to a cup of Coke?"

"Coke? Forget it, let's just use the cold and simplified air."

"OK."

"Girl, do you know why your three major airlines are losing money to the point of selling their money?"

“…”

"Because the business elements were not brought to the extreme."

Ge Xiaotian took the water cup handed by the flight attendant, "It looks tall and in essence it is a ticket-selling business. Just like the shell of this plane, sprayed with xba basketball stars, or Sancha Cup football stars holding up ODE advertisements, occasionally sending another batch of free air tickets to the team, which is both advertising benefits and attracting popularity. There is also the back of this seat, without Qingshan Traditional Chinese Medicine Hospital, or the words "Purple Golden Flower, Fu Doll, Infertility, and Quick-acting Heart-Saving Pill". I feel that you are not in business. Especially this blanket, what a good advertising space, hot springs, hotels, big swords, Mamasang..."

“…”

Dao Shiyi, who was sitting next to him, couldn't stand it anymore, "Boss, please sleep for a while."

"Girl, remember, go back and tell your chairman. If you don't follow what I said, you will still lose money next year. In 2002, the superiors decided to open the private aviation field. If you are acquired by me, what a delicate girl, wearing black silk to move bricks, it will definitely look good."

“…”

Dao Shiyi waved his hand secretly and signaled the flight attendant to go and work, "Boss, how can we do the Internet upgrade?"

"This time, the biggest benefit of communicating with Jiusuo is not to send out quantum computer theory or obtain visible light communication technology, but to activate the receiver that combines purple bee technology and visible light communication."

Longtian Zifeng technology is not behind, but it only shares too much, resulting in slow internet speed. If sharing is adjusted to exclusive, 30m internet speed can be enough to reach the 5g era.

But the network speed is network speed, bandwidth is bandwidth, and delay is delay, so it cannot be confused.

For example.

It takes 10 seconds to pump a water tank full of ten cubic meters, and the speed is: 1 cubic/s, which is the network speed.

The bandwidth is how many cubic cubic water can pass through the water pipe per second.

The delay is...

After laying the water pipes, you need to notify the pump administrator to start. The administrator receives a message that when the well water flows into the water tank, how much time will take at this stage is the delay.

The further away from the water tank is from the water pump, the longer the water pipe, or there is a message transfer station in the middle, the higher the delay.

In addition, it is necessary to consider the administrator's reaction time, as well as whether the water outlet at the end of the water pipe is smooth, that is, whether there are viruses in the computer or server, and whether the hardware performance is excellent.

If a car suddenly slams the water pipe in the middle of the way, it is called the network cable being pulled out...

Of course, this is just a metaphor.

Also, optical fibers with the same bandwidth, different materials, can withstand different optical powers.

Just like the water flow rate in the water pipe, the material is good and the water pressure is strong, the flow rate will be fast; the material is poor and the water pressure exceeds the limit, the pipe will explode, or the water pressure is not strong, and the water flow will be soft and thump...

After listening to these, Dao Eleven, who mainly studied the materials, was thinking, "Fusing purple bees, complementing each other, arranging two communication modes according to the environment, and gradually updating the SG equipment and only one card."

"right!"

Ge Xiaotian took out the SGPad and found a set of data, "Ji City Tiancheng Plaza, with a daily passenger flow of 50,000 and a holiday passenger flow of 100,000. A fiber optic service for 100,000 people. There are 1,000 fiber optic and 1,000 base stations. How much? It seems a lot, but for a CBD covering an area of ​​200,000 square meters and a building area of ​​800,000 square meters, it is too small. You have to pull 10,000 fiber optics, or set up super base stations by relying on cables."

"Improve the number of optical fibers and optical cables, and change the sharing of hundreds of people to sharing ten people, or five people."

"Yes, I used to worry that there were too many base stations and that the parameters would be microwave interference. Now, with visible light communication technology, such as malls, supermarkets, home appliance cities, furniture cities, especially underground pedestrian streets with poor signal, underground parking lots, etc., Zifeng can be changed to visible light, while the extra Zifeng base stations are moved outdoors."

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

"Absolutely, it is best to create a volume that can wrap around the parent star for dozens of times. After the price, the cost will be reduced, and then it will be connected to the countryside and replace the telephone line."

Ge Xiaotian had figured it out as early as when he was communicating with the Nine Society.

There are many places where China cannot access the Internet. Instead of competing with North America for Internet access speed, it is better to continue to expand the SG series market.

Moreover, as long as the number of optical fibers increases, Zifeng sharing becomes exclusive, and the download speed can reach 30m.

The 3g download speed is only 2m, and even 4g download speed will not exceed 10m.

Our side can still maintain the lead.

As new optical fibers become popular, they can improve their own gear.

Unless the other party produces 5g, or... shoots more than 6,000 satellites.

"Why?"

Ge Xiaotian blinked, "How many agents and spies are left behind?"

“More than thirty.”

"Let them spread the news, just say that Long Tian has developed a shot of twenty stars with one shot, and is preparing to secretly start the Cyber ​​Starlink project. By the way, hand over the Starlink technology to the agents and spies."

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

"Double-sided spies? It's very much my wish! By the way, let Lao Wang hold a press conference first and put forward the idea of ​​"the light column falling from the sky" to prove that Long Tian really wants to build a cyber starlink to stimulate the technology alliance. If they decide to invest in cyber starlink one step ahead of Long Tian, ​​then the fun will be great."

"But once they get it done, we'll be behind."

"Are you stupid? There are more than 6,000 satellites, and a single life span is calculated at the highest ten years. If there is another round in ten years, who can withstand it? It is necessary to use graphene technology to improve it to twenty years, or even longer. But the problem is, do they have graphene?"

"Sold them a batch secretly, and then increase the price?"

"You are so bad!"

“…”

"The biggest problem now is how to reduce latency with old-fashioned fibers."

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

"Have I said it?"

"What you said to Jiu."

"I'm used to blowing, but I didn't expect it to be useful."

“…”

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

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

"First draw a batch of inventory to complete the Dongshan industrial chain, upgrade the Zifeng Network to withstand the impact of 3g."

"clear."

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

"Okay, by the way, the boss, there are two days left in New Year's Day. Do you want to have an event?"

"Forget it, it's not good to always show up in public. It's not good to be too high-profile. In this way, I use my elf to shoot a short video to wish the people of the whole country a New Year, and send hundreds of millions of red envelopes."

“…”

…………………………

December 29th.

Ge Xiaotian arrived at Qinggang overnight.

Tiancheng Electrical Industry Group is relatively scattered, with part located in Ji City, part located in Dongshan Fifteen City, and part located 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, extending to Jinsha Beach in the northeast and to Zhaoshi in the southwest.

There are numerous piers along the way, and at first glance there are berths.

On the central coast, there are tower cranes, gantry cranes, transport belts, transport vehicles, docks, floating docks, filling the blank area near a hundred miles.

Further down, warehousing, logistics, auto repair, tarmac...

In the wilderness in the distance, there are bright lights and countless super-large workshops covered with the earth, which is for the "Tiancheng Electrical Industry".

Here is the largest precision instrument manufacturer in China.

Here is the most complete heavy equipment manufacturing factory in China style.

Here is the most diverse electrical equipment manufacturer in China.
