Bit Mania [Hacking]

Luo Zixin followed Liang Zhang upstairs. Although he called him brother-in-law, he was not related to Du Feixue at all. Luo's father and son in Huanjiang Town went through the most difficult period.

In Zixin's memory, perhaps more from the language fragments spoken by his father, he learned that when he was very young, probably in the early 80s, he and his father were always traveling between multiple cities.At that time, Luo's father was working at a metropolitan dock for a while, but he had an accident at work and was hit by a cargo box that fell from the car. After the treatment, although he was able to stand up and take care of the basic life by himself, The waist can no longer be stressed, and I can't do physical work at all.

He couldn't move heavy objects, and couldn't even stand and walk for a long time. After the dock gave him a medical bill that didn't help, he sent Luo Hui away.As a semi-disabled person, Luo's father had difficulty finding the cheapest job, and the consumption in big cities was high. Facing the rising housing prices, the breadwinner of the family gritted his teeth and brought his youngest son to Huanjiang Town to settle down. Relying on the electrician knowledge I learned before to repair electrical appliances for people to make ends meet.

The people in the town are simple-minded. Neighbors heard that he was injured due to work, and they felt a little bit of admiration in their hearts. In addition, Luo Hui's own electrician skills are good, he has lived in the city, and he understands more advanced things, and the price is cheap. In fact, people were willing to patronize his business and help him, so word spread, and people nearby came here especially if their machines were broken.

In order to take care of Master Luo's physical inconvenience, the townspeople would bring some small and light electrical appliances to Luo's house for repair, but for large household appliances such as TV sets and refrigerators, it is more practical to come to repair them.Originally, according to Luo's father's physical condition, such a business must have more than enough energy, but the turning point happened to the young child next to the man——Luo Zixin.

Since Zixin first came into contact with the knowledge about electrical engineering and electronics from his father, he was immediately fascinated by this magical electronic world. Those electromagnetics, those logics, and those signals are so incredible and ever-changing in his eyes. Human beings use it to make electrical appliances with different functions, which makes people dazzled.

Full of curiosity and amazement, whenever a man sits in front of the workbench to repair electrical appliances, the child will move a small chair and sit beside him, pointing to various components and asking about their principles and functions. Running around or crying begging for toys, for a single father, a child who can sit obediently next to him when he is working is obviously much more worry-free, so Father Luo is also willing to use simple and vivid language. Explain to Xiao Zixin to attract his attention.

His father's subtle influence had a great influence on Zixin.When he started to read and write, the electrician's manual became his enlightenment reading.As his son's astonishing talent gradually revealed, in order to meet the needs of the child, Luo Hui borrowed second-hand teaching materials on electrical engineering from universities in nearby cities and took them home for the children to read.

From there it was out of control.Luo Hui's electrician's reference book had been torn apart, and was moved by Luo Zixin to a high cabinet, and all the contents of the book were deeply engraved into this young head, and the indoctrination of college textbooks made it even more difficult. His theoretical foundation is getting deeper and deeper, because those textbooks are all borrowed from college students in the city. It is very inconvenient for Luo Hui to go to the city, and he has to return it soon. The difficult learning conditions make Zixin's reading speed difficult. Very quickly, I devoured the knowledge in the books every day, and almost never forgot those contents.

As the reputation spread, Luo's father received more and more jobs. Zixin started as a helper at the beginning, and soon let his father with limited physical strength relegate to the second line, and became the leader of the maintenance shop himself.Later, when he was a little older, the boy began to repair large household appliances for people on a bicycle. Compared with the original minor repairs, this kind of work is much more difficult, and the income has also increased. He was not favored, and later gradually became famous.

Although it is very convenient for this big brother to be sent to the Luo family for repairs, there is no need for Luo Zixin to come to the door, but it is obvious that the Du family wants to call Zixin over to Juju.

Zixin didn't have any resistance to this, although the Du family had a god-sister who liked to pinch his face and tease him, but he did treat this family as relatives.

There was the sound of pattering footsteps behind them. The two boys turned their heads and saw Du Feixue following up aggressively: "I want to supervise you!"

Liang and Luo looked at each other, opened the door respectfully, and invited the aunt to enter.

Walking into the room, Luo Zixin saw a black telephone-shaped object, which was stuck on the base and placed safely in the center of the table. It was covered with a thin cloth, and it could be seen that it was carefully cared for by the owner. The first time he saw this thing that he had only seen in the news before, the boy couldn't help swallowing, walked forward cautiously, wiped his hands on his clothes subconsciously, and looked back at the two young men. After getting a positive smile from the other party, he reached out and took the big brother out of the base.

This wireless communication tool is quite heavy, like a big glossy black brick.The Huaguo cellular mobile network, that is, the TACS full-access cellular mobile system was officially put into use in the winter of 1987, and the mobile phone, as a civilian facility, was introduced into Huaguo in batches in the early 90s. Zixin is now The mobile phone in my hand was the MobiraTalkman produced by the world-renowned telecommunications provider Mobira at that time. Perhaps this company is not well known to everyone, but his name later became a household name-Noja!

Speaking of which, his brother-in-law is definitely an avant-garde and capable young man in this era. The reason why the "big brick" in Luo Zixin's hand was called "Big Brother" was because at that time, he had a Such a thing means that you are a genius, just like the "big brother" who is older than the "big brothers" in Hong Kong and Taiwan police movies.

This is not an exaggeration. In the era of 1991, if you owned a big brother, you would take it out and put it in front of you at the banquet or on the negotiating table, and the other party would become polite when talking to you. There are commercial and quantitative.

Luo Zixin took the manual from Liang Zhang and read the introduction. As he continued to deepen, surprise gradually appeared in his eyes. At the same time, his mind was running fast. However, the radio can reach three digits, so he has also dabbled in wireless communication. Combined with the introduction of data such as transmission power and frequency band in the product manual, these parameters that are complicated and difficult to understand in the eyes of ordinary people have become in his hands. The key to unlocking the circuitry of this Big Brother structure.

The general working principle of the machine in his hand quickly took shape in Luo Zixin's mind, while Du Feixue's chirping voices like a bird kept coming from the side.

"Well, this is so high-tech! Dai Xiaoxin, don't you have any electrical appliances that can't be repaired, you should give up now, haha!"

It would be great if it could be disassembled and looked at... Zixin was conceiving the electronic structure of the big brother, when he heard someone talking, he subconsciously looked up at the source of the sound, and opened his big eyes blankly: "ah?"

Even Liang Zhang couldn't help laughing now, and Du Feixue reached out and rubbed Daixin's head viciously, until his hair was messed up.

The touch on his head woke Zi Xin up, and he held his eldest brother in front of the two of them: "Does it look like nothing is wrong, but you just can't receive or make calls?"

"I just said... Huh?" Feixue was taken aback for a moment, and then opened her mouth: "Daixin, how do you know?"

Luo Zixin pointed the big brother's screen at the two of them, and pointed to the word "NOSVC": "This is the abbreviation of 'NOservice', which means that communication is not available now."

Liang Zhang nodded, and directly asked the key point: "Then how can it communicate?"

"It has lost contact with the radio network. There are two possibilities. One is that the reception signal is too weak, and the other is that our current location is not within the service range of the radio network."

After a pause, he continued: "The second situation is impossible. We have set up a complete radio base station and mobile switching center in the west of Huanjiang Town a few years ago, which will definitely cover the place where we are now. , and there are no obstacles such as mountains, so the problem should be in the signal reception."

The other two were stunned for a while: "Then what should we do?"

"What should I do?" Luo Zixin took the mobile phone to the window sill and looked up at the rainy sky: "Just modify the satellite..."

"Crack." A jade hand rubbed his head again: "Reform the satellite? What nonsense are you talking about!"

"...I'm telling the truth." The boy shook his head dejectedly, then suddenly grabbed the big brother's hand and stretched it out of the window.

The other two people in the room turned pale with fright, and rushed forward to stop him: "Hey, don't throw it down in a fit of anger!"

Luo Zixin didn't speak, just stared at the phone screen quietly, and after a while, motioned for the two to look: "The signal in the room is not good, if you stretch it out of the window, you can barely reach the signal strength of two bars, which is enough for calling .”

Du Feixue stomped her feet violently, and stretched her claws towards the boy's innocent ears: "...you bastard, you want to scare me to death! That's 3 yuan! It's not enough to sell you!"
