The Goddess Shines on America

Everything is a matter of course.

The development of ADSL technology is not very difficult, at least for Alice. In fact, she invented this technology by taking advantage of the trend of routers before she graduated from San Anto Elementary School, that is, when Cisco was founded not long ago. It's just that in a short period of time, there is no need to put it on stage at all.

After all, ADSL is such a thing, it is hard not to let her think of it when developing routers, and the term broadband access is familiar to all Chinese people. Make a phone call, and there will be an errand worker with a contract and a router to come to the door to install it, but it is a real part of daily life.

This technology is very complicated. For those who start research from scratch, that is, Bell Labs in history, it really takes a lot of time and energy to explore the experiment step by step. But it is simple and simple. When Alice is not stingy with using telekinesis to assist in hardware modification, it is still very easy to achieve the level of "obtaining a patent".

The full name of ADSL is Asymmetric Digital Subscriber Line, which is a part of the DSL family, that is, Digital Subscriber Line. This is a technology developed by Bell Labs for video-on-demand services in 1989, using twisted-pair copper cables to transmit high-speed data. It's a pity that the video-on-demand service failed to rise at this time, so the DSL technology was temporarily abandoned. On the contrary, after the great development of the Internet in the 1990s, due to the low cost and low cost based on copper twisted wires, ADSL was restarted, making it easy for ordinary users to achieve high-speed networks.

This technology itself is not difficult, because its basic principle is really just to separate three channels for the twisted pair. As long as someone with a heart finds the target and develops it, a small laboratory can register a patent in as little as a few months, even in the early years of a year. It's a pity that since Alice aimed at this concept as early as 1984, it has nothing to do with Bell Labs.

Technology research and development is not difficult. What really takes time is the process of operators completing the laying of relevant infrastructure and finally realizing broadband access to households.

For a long time, from the perspective of communication users, the whole process is that the user's telephone is connected to the community or even the town switching office through the ordinary twisted copper subscriber line, and then enters the public switched communication network until it is connected to the other party's telephone. Phone, so as to realize the conversation between two phone users.

This is the frequency band that broadband provides for traditional analog phones. Its frequency is between 300 and 3400 Hz. This is actually a very low speed. It is not difficult to understand the hardware standard of Lenovo's world's first telephone. Therefore, in order to better adapt to the needs of modernization, operators provide users with modems to increase the speed, so that the data signal speed can be as high as 33kn/S to 56kb/s, and can realize data communication with the other party through the analog voice band.

In other words, before the arrival of ADSL technology, the data transmission speed of Internet users is limited to this. This method of accessing the Internet that occupies a telephone line can still meet the needs in the early years, but with the continuous popularization of even this low-level technology, people's demand for higher-end technology will naturally rise.

The transmission rate of the copper twisted wire can be very high, but the switches in the communication network are limited. It only has one frequency band for telephone communication, so when the user's Internet data comes, it can only treat it as telephone communication data. Therefore, since the copper twisted wire itself does not limit data transmission, as long as the narrowband switch can be avoided, the user can transmit the Internet data to the communication network at high speed, and this is the core purpose of the DSL series technology.

Well, in fact, after understanding the whole cause and effect, Alice also knew that this was Cisco's problem. Regardless of whether it is Cisco or any company that produces switches, it is considered good if everyone can develop switches and sell them for money. To improve the Internet speed of the public, the products can distinguish digital information? Why are you all so idle?

Therefore, this project still has to be solved by the network provider.

"This is a business with a very large workload, but there is no doubt that it will efficiently promote the development of the entire society. In this regard, Cisco can provide relevant technical support, such as the authorization of DSL-related technologies, and infrastructure network transformation. Interface patent authorization... Yes, Mr. Locke, this technology, as I explained to you, is not too technically advanced, but very difficult to popularize, so it is even necessary for us to establish a standard for this , what do you say?"

The meeting was still going on, and Alice, who was well prepared, had already distributed the materials related to DSL technology. At this time, all the shareholders in the audience had finished reading, and the representative CEO Barton Locke fell into deep thought.

"This is indeed a blueprint with outstanding prospects." After a moment of silence, he took a long breath and said, "But please let me discuss it carefully with the board members. Miss Wang, and His Royal Highness, it is getting late How about we go to the restaurant downstairs for lunch?"

It's getting late indeed, and the reading of materials on ADLS, SDSL and even HDSL under the DSL technology has taken up a good part of the conference's time. Of course Alice was so happy, she patted her belly and said, "Thank you so much, Mr. Locke, I have heard that British Telecom's cafeteria has hired several skilled French chefs, I want to treat myself well .”

Afterwards, everyone walked out of the conference room talking and laughing. When he first walked to the lobby of the floor, Prince Charles seemed to be pacing casually, but he was just right side by side with Barton Locke.

"Oh, Your Royal Highness..."

"AT\u0026T in the United States, and even Bell Atlantic, have a lot of competitive pressure on us." He said calmly: "If you don't choose to cooperate with her, then this girl will definitely choose our competitor. Mr. Locke , when a new industry is booming, who is the number one is very important, I believe you must understand this truth better than me."

"That's nature, that's nature."

Barton Locke and the Crown Prince slowly followed behind the team. Chad, the director of the technical department, had shrewdly entangled Alice. When the two were discussing technical details at the elevator door, the two of them whispered behind the team. talking.

"However, Your Royal Highness, if we really want to implement this plan, transforming the existing network lines is one aspect. We must also buy a huge order from Cisco. Since this technology was proposed by Ms. Wang, her flagship products It will definitely play a key role in this process, so the cost needs to be calculated in two ways.”

There was no time to say more, because the elevator had already opened, and Prince Charles laughed loudly: "Come on, let's go and taste a delicious French meal together, Alice, don't take my share away !"

"So when it comes to setting the standard for the network cable interface... oh yes, Your Highness, I will definitely grab every ounce of lobster on your plate!"

After a friendly pat on the shoulder of technical director Chad, Alice was the first to walk into the elevator.

The executive restaurant is located in a remote corner of the cafeteria. The decoration style here is quite exquisite, and there is a whole glass window that allows people to see the bustling streets of London. As for the whole lunch itself, of course, it is not just for eating. Before waiting for the dishes to be served, some people need to ask Alice a series of questions.

Of course, it will not be a matter of this cooperation for the time being, and it will be mentioned again when the meeting is held in the afternoon.

"Are the rumors true?" Jessica, one of British Telecom's executive shareholders and the CFO's redheaded girl, asked curiously: "There is a report in the financial section of the Times that TESCO is worth 140 million pounds. The market value was taken away, and the biggest transaction was made by you?"

"Ah, TESCO, yes, Jessica." Alice smiled very calmly: "The net profit of 34 million pounds, thanks to its roller coaster a few days ago, I didn't expect to make so much money Woolen cloth."

Prince Charles, who was listening, twitched his eyes.

Jessica undoubtedly raised an eye-catching topic. Seeing Alice's easy answer, another executive asked: "How did you think it would have a roller coaster? God bless, I just happened to be in it. Those who have short positions during the fall will suffer a lot.”

"TESCO...it's the largest supermarket chain in the UK."

Alice looked at the first dish on the table and said: "As of now, it has hundreds of branches in the UK alone? And most of them are concentrated in London. Everyone, London is a financial city, so Do you think, when the stock market crash has left so many people without money, who will hang out in the supermarket?"

"Yeah, so..."

"So it's going to go down right away, but it's going to go up again right away."

Alice smiled and watched the second dish being served: "Because after all, what you buy in the supermarket is daily necessities, and even fresh food. When people are just short of money, they will subconsciously think of going to the supermarket less, but they will really be affected. After all, the impact is only on luxury and consumables, so you don’t go to the supermarket... after all, don’t you want to go?”

Seeing that everyone in the audience was savoring her own words, Alice smiled slowly again and picked up the wine glass.

Normal, after all, for this group of people who watch the financial channel every day, their recent multi-party arbitrage in the global stock market must have attracted countless people's eyes. So when she shared her investment philosophy for a while, even though these adults were at least twice her age, she had to listen obediently.

"Recommend a sector worthy of investment now." When the third dish was served, Alice chuckled, and was satisfied to see the eyes of this group of people lit up: "Game and film industry, yes For people who are unemployed at home, there is nothing cheaper to consume entertainment than this. The more depressed the economy is, the more this type of industry will flourish!"
