The development of ADSL technology is not very difficult, at least for Alice. In fact, she invented this technology as early as before she graduated from Sant'Anto Primary School, that is, not long after Cisco was founded. It's just that in a short period of time, there is no need to put it in front of the stage at all.

After all, ADSL is such a thing, it is difficult for her not to think of it when she was developing routers, and the term broadband home is familiar to all Chinese. Make a phone call, and there will be an errand worker with the contract and router to report the installation, but it is a real part of daily life.

This technology is complex and complex, and it does take a lot of time and effort for someone who is starting from scratch, that is, the historical Bell Labs, to explore the experiment step by step. But it's simple and simple, and when Alice doesn't hesitate to use the telekinesis to assist in hardware modification, it is still easy to achieve the level of "patenting".

ADSL stands for Asymmetric Digital Subscriber Line, which is part of the DSL family, that is, the Digital Subscriber Line, which was developed by Bell Labs in 1989 for the video-on-demand service, using copper twisted pair to transmit high-speed data. It's a pity that the video-on-demand business failed to emerge at this time, so DSL technology was temporarily abandoned. On the contrary, after the great development of the Internet in the 90s, due to the low cost of copper stranded wire, ADSL was restarted, making it easy for ordinary users to achieve high-speed networking.

This technology itself is not difficult, because its basic principle is really nothing more than three channels for twisted pairs. As long as someone has the right goal to develop it, a small laboratory can register a patent in a few months, not more than a year. It's a pity that since Alice aimed at this concept as early as 84, there is no more to do with Bell Labs.

Technology research and development is not difficult, but what really takes time is the process of operators laying relevant infrastructure and finally realizing broadband to home.

For a long time, from the perspective of communication users, the whole process is that the user's telephone is connected to the community and even the town exchange bureau through the user line of the ordinary twisted copper wire, and enters the communication network of public exchange, until the other party's telephone is connected, so as to realize the call between the two phone users.

This is the frequency band provided by broadband for traditional analog telephones, and its frequency is between 300~3400Hz, which is actually a very low speed level, and 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 rate, so that the rate can be as high as 33kn/s to 56kb/s data signals, and the data communication with each other can be realized through analog audio tapes.

In other words, before the advent of ADSL technology, the data transfer speed of Internet users was limited to that. In the early years, this method of using phone lines was able to adapt to demand, but as even this low-level technology became more popular, the demand for higher-end technology naturally increased.

The transmission rate of copper stranded wire can be very high, but the switches in the communication network have limitations. It has only one frequency band for telephone communication, so when the user's Internet access data is transmitted, it can only treat it as telephone communication data. Therefore, because the copper stranded wire itself does not limit data transmission, as long as it can avoid narrowband switches, users can transmit Internet data to the communication network at high speed, which is the core purpose of DSL series technology.

Well, in fact, when she learned about the whole cause and effect, Alice also knew that it was Cisco's problem. Whether it's Cisco or any company that makes switches, it's good that you can develop a switch and sell it for money, specifically to improve the speed of the public's Internet and make the product digitally distinguishable?

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

"It's a very large business, but there is no doubt that it will be effective in promoting the development of a whole society. In this regard, Cisco can provide relevant technical support, such as the licensing of DSL-related technologies and the licensing of interface patents in infrastructure network transformation...... Yes, Mr. Locke, this technology, as I explained to you, is not too technical, but it is very difficult to popularize, so we even need to establish a standard for this, you say?"

The meeting is still ongoing, and Alice, who has been prepared for the early stage, has also distributed DSL technology-related materials. At this time, all the shareholders in the audience had finished reading, and Barton Locke, as the representative CEO, was lost in thought.

"It's a very promising blueprint. After a moment of silence, he let out a long breath and said, "But please let me discuss it with the board members." Miss Wang, and His Royal Highness the Crown Prince, it's not early yet, how about we go to the restaurant downstairs for lunch first?"

It's really not early, and the reading of ADLS, SDSL and even HDSL materials under the entire DSL technology occupies a good part of this session. Alice, of course, was so happy, patted her belly and said, "Thank you so much, Mr. Locke, I have heard that the canteen of British Telecom has hired several highly skilled French chefs, and I should treat myself to a good meal." ”

Then, everyone walked out of the conference room with laughter and laughter. As he first reached the floor hall, Prince Charles seemed to be pacing nonchalantly, but he was just right alongside Barton Locke.

"Oh, His Royal Highness the Crown Prince......"

"AT&T in the United States, and even Bell Atlantic, put a lot of competitive pressure on us. He said calmly, "If you don't choose to work with her, then this girl will definitely choose our competitor." Mr. Locke, when a new industry is booming, it is important who is the number one, and I believe you must know this better than I do. ”

"That's nature, that's nature. ”

Barton Locke and the Crown Prince slowly followed the line, Technical Director Chad had shrewdly pestered Alice, and the two of them whispered to the rear of the group as the two discussed technical details at the elevator door.

"However, His Royal Highness the Crown Prince, if we really want to implement this plan, it is one thing to renovate the existing network lines, and we will definitely need to buy a huge order from Cisco. Since this technology was proposed by Ms. Wang, her flagship products will definitely play a key role in this process, so the cost needs to be calculated from two aspects. ”

It was too late to say more, because the elevator had already opened, and Prince Charles laughed loudly: "Come on, let's go and taste a table of exquisite French food together, Alice, don't rob me of my share!"

"So in terms of setting the standard of the network cable interface...... Oh yes, Your Highness, I'm going to snatch every penny of lobster from your plate!"

A friendly pat on the shoulder of Technical Director Chad, Alice was the first to step into the elevator.

Located in a remote corner of the canteen, the Executive Dining Room is exquisitely decorated with glass windows that offer a view of the bustling streets of the city. As for tidying up the lunch itself, of course, it will not be just for the sake of eating, and there are a series of questions that need to be asked of Alice before waiting for the dishes to be served.

Of course, it won't be a matter of cooperation for the time being, and that will be mentioned again in the afternoon.

"Are the rumors true?" Jessica, a redhead from the CFO and one of BT's executive-level shareholders, asked curiously: "The Times has a report in the financial section that Tesco has a market value of 1400 million pounds and you made the biggest deal?"

"Ah, Tesco, yes, Jessica. Alice smiled very calmly: "Thirty-four million pounds of net profit, thanks to its roller coaster a few days ago, I didn't expect to make so much money." ”

Prince Charles, who was listening on the sidelines, twitched the corner of his eye.

Jessica undoubtedly stirred up a high-profile topic, and seeing Alice's easy answer, another executive then asked, "How did you think it was going to be a roller coaster? God forbid, I just happened to be in the middle of it, and I lost a lot." ”

“tesco…… It's the largest supermarket chain in the UK. ”

Alice looked at the first dish and said, "As of now, it has hundreds of outlets in the UK alone, and most of them are in London." Ladies and gentlemen, London is a financial city, so who would go to the supermarket when the stock market crash left so many people starved of money to spend?"

"yes, so ......"

"So it's going to fall right away, but it's going to go up right away. ”

Alice smiled and looked at the second dish 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 indeed subconsciously think of going to the supermarket less, but what will really be affected is only luxury goods and consumables, and go to the supermarket less...... Isn't it going to be there after all?"

Seeing that everyone in the audience was savoring their words, Alice smiled slowly again and raised her glass.

Normal, after all, for these people who watch financial channels every day, their recent multi-party arbitrage in the global stock market must have attracted the covetousness of countless people. So when she shared her investment philosophy a little, she had to listen obediently, regardless of the fact that this group of adults was at least twice her age.

"Let's recommend a sector that is worth investing in now. Alice chuckled as the third course was served, and saw with satisfaction that the eyes of the group lit up: "The game and film industry, for the unemployed at home, there is nothing cheaper than this for consumer entertainment." The more the economy is sluggish, the more developed these industries will be!" )
