"Actually, the most dissatisfied thing with this pager is that it is too small. Fang Chen said slowly.

Small?

Ma Huateng was a little dumbfounded and said: "Isn't miniaturization what electronic products have always pursued?" ”

The development trend of computers, big brothers, and even Motorola pagers is getting smaller and smaller, so how did Mr. Fang come in reverse.

"Big! both good looks and justice!" Fang Chen said categorically.

It is true that general electronic products are getting smaller and smaller, but the display category, or electronic products related to direct viewing by the eyes are not, and they should all be made bigger and bigger.

The most typical example, the screen of the smart phone is getting bigger and bigger, and even the iPhone, which was originally going to hold the 3.5-inch screen to death for the rest of its life, finally didn't honestly make the screen bigger and bigger, and then not only the PLUS version came out, but even the 6.5-inch MAX version came out.

And you must know that the 6.5-inch screen area is three times the area of the 3.5-inch screen, and in front of a larger screen, what grip is not worth mentioning at all.

In addition, why do people care so much about folding screens, isn't it just to have a larger screen without affecting portability?

This trend, Fang Chen believes that even if Jobs is still alive, he can only obey, if he still holds the 3.5-inch screen, then only the iPhone will die, and the development of the world is like this.

So big is appearance, it is justice!

"For example, if you have two 21-inch and 29-inch TVs in front of you, which one would you choose?"

"Twenty-nine inches for sure!" said Ma Huateng without hesitation.

Fools also know that big TV is more enjoyable and comfortable.

"That's not it. Fang Chen said.

Ma Huateng scratched the back of his head, "But this is not a TV, and there is nothing to see." ”

He probably understood what Fang Chen meant, but the pager was really nothing to look at, not to mention that the mainstream pagers are still digital pagers, just a few numbers are displayed on it, even if it is Motorola's Hanxian pager, there is not much content in a message, so it is enough to display eight Chinese characters in one performance, and it is enough to press the page down button twice.

"Today's pagers, there is indeed no need for screens and viewing, but without demand, we can create demand!" Fang Chen's eyes flashed with an inexplicable light.

Ma Huateng covered his forehead, he felt that he had been in college for four years, how could he not understand what Mr. Fang meant!

What is the need for pager to let yourself know who is looking for you, isn't it?

Not to mention the mainstream digital display pager, let's say that the Hanxian pager, Motorola's Hanxian pager, each message can only display a maximum of twenty words, which can only meet the user's need to know who called him, but if each message can display up to seventy words? ”

"For example, what time to pick up the children from school, or go to the vegetable market to sell a pound of potatoes when they come back, and even express their thoughts and love through this message. Fang Chen said slowly.

In 2012, the annual number of mobile text messages sent across the country reached 900 billion, which greatly changed the impact of mobile phones on people's lives.

It's just that after having WeChat, especially middle-aged people, the elderly will use WeChat, and SMS can only helplessly withdraw from the stage of history, after all, everyone is not even too lazy to use SMS to greet the New Year, and the biggest role of SMS has been reduced to receiving verification codes.

But at this time, SMS is still a relatively new feature, and it has not even appeared in the world.

The world's first text message in history, which appeared in December this year, was sent through the GSM network, one of the main standards of 2G.

As for why he wanted to turn on the SMS function for the pager, it was because the pager was too inconvenient.

Of course, compared to the previous era when there were no pagers, pagers did greatly meet people's needs for timely information, but for Fang Chen, a person who was reborn once, it was really troublesome.

After receiving the other party's information, the pager actually doesn't know why the other party is looking for him, and if he wants to know, he must immediately find a way to find a phone call back.

After all, the role of code is still too limited.

And these days, except for those who have a phone in the office and can connect to the Internet, most of them have to run out to find a public phone to call back.

With the current penetration rate of fixed telephones, it is basically necessary to run three to five hundred meters, or even farther, to find a public telephone, and there is a considerable possibility that you need to queue up.

And the person calling also needs to wait honestly next to the phone, as for when the other party will be able to call back, only God knows.

Sometimes it's normal to return a phone call, toss for half an hour, or even longer, and tossing such a circle can kill people.

For Fang Chen, this method is as backward as a primitive society, which is why he directly skipped the pager and bought Big Brother.

Although Big Brother has the problem of being bulky and having a bad signal, he can call out at any time no matter what, no need to wait, and he is not short of money.

And after the SMS function, there is no need to be so troublesome, some unimportant things, such as what he said just now, what time to pick up the child, go home to buy groceries, etc., a text message passes, the other party will know, and there is no need to go so troublesome to call back.

Even to say an extreme thing, the child is sick, the mother asks the father to come over, according to the current way of using the pager, basically the mother needs to wait next to the telephone for dozens of minutes, enduring the anxiety and apprehension in her heart.

But with text messages, you can directly tell the father what the child is sick with, which hospital it is in, what ward it is in, and so on, completely saving these unnecessary anxiety and waiting.

And he also believes that people need to use pagers to deliver more information, or they wouldn't have invented codes like those in Digital Love.

For example, 3155530 - it's all about I miss you, 570 - I'm angry with you, 000 is kissing or something.

Ma Huateng was stunned for a moment, Fang Chen's words seemed to open a new door for him, the pager could still play like this, but why did he feel a little fanciful, or unreliable?

After thinking carefully about his understanding of the wireless paging system in the past few years, especially in the past few months of research, he felt that Fang Chen's idea was very good, but it was unrealistic to realize.

In other words, it really can't be done with existing technology.

At present, the Chinese pager system adopts a manual connection method, relying on each paging receiver through ROM, that is, semiconductor memory, to establish a simple Chinese character library inside the pager.

When the system is working, the operator of the paging center receives the user information, and then enters the paging operating system verbatim in a concise arrangement with a five-stroke font, and then sends a paging signal with POCSAG encoding.

And then on the user side, that is, on the paging receiver, there are two Hanxian solutions.

One is a code-type Chinese character pager, for example, a common phrase composed of a digital decimal numeric code, such as 254-wife, 255-son, 783-please get up, etc.

The operator enters 255,783 in the paging operating system, and after the pager receives the message, it can display the Chinese message such as please get up on the display screen.

But this is a simple solution, but it eliminates the problem of memorizing and carrying a code book.

The second solution is the real Chinese character pager, which is based on Chinese characters and codes.

For example, Motorola Huaxia's latest consultant-type Chinese pager contains the standard GB-2312-80 simplified Chinese character library.

But the problem is that each Chinese character needs to be represented by 14 bits, and an information codeword is only 20 bits, and in the case of a POCSAG encoding method with only sixteen information codewords, 320 bits, twenty Chinese characters occupy fourteen information codewords, 280 bits, and finally there is an address codeword with an information codeword.

In this way, 20 Chinese characters already occupy 15 information code words, which is equivalent to the entire POCSAG code group.

Therefore, the paging station of the Chinese character pager must limit the paging content, otherwise the paging users that can be accommodated by each channel will be greatly reduced, which is why there is still a code in the second set of solutions.

"I think it's hard because of the way POCSAG is encoded, and you know what a POCSAG code is, right?" said Ma Huateng tactfully but uncertainly.

Fang Chen glanced at Ma Huateng, Ma Huateng had only been engaged in correspondence for a few months before he dared to show off in front of him.

He is a person who has been doing communication for more than 20 years in his previous life, how could he not know the POCSAG code, if he is not afraid of scaring Ma Huateng, he really wants to talk to Ma Huateng about what 5G is, let him open his eyes.

The POCSAG code was successfully researched by the British Post Office and recommended by the CCIR as the international 1 number for wireless paging in 1978, which is a widely used paging code in many countries.

It is also the coding format used in China's public wireless paging system stipulated by the Ministry of Posts and Telecommunications of China's "Wireless Paging Network Technical System", which has the advantages of high coding efficiency, strong error correction ability and large address capacity.

"I know, let's develop my own code. Fang Chen looked at Ma Huateng intently, and said very seriously.

Develop your own coding!

Ma Huateng couldn't help but gasp, he was a little frightened by Fang Chen, how much effort did the British General Post Office make to develop it for the POCSAG code.

Not to mention anything else, from the POCSAG code is now the international wireless paging system coding format, you can see the power of the POCSAG code.

Other countries or companies have not developed other coding formats, but they have all been defeated by POCSAG codes.

"You're not kidding, are you?" said Ma Huateng timidly.

Fang Chen nodded heavily, he was naturally not joking.

The POCSAG code is indeed good, and when it was just developed in 1976, it can indeed be called excellent, which greatly solves the problem of information transmission of the wireless paging system.

But now it is 1992, with the rapid development of the paging industry, the number of users has increased dramatically, and the system using the POCSAG coding system is no longer enough.

Therefore, Motorola developed a new high-speed coding system in 1993 - FLEX, and in 1996, it was selected as a high-speed wireless paging coding format for posts and telecommunications in China.

With FLEX, the problems that Ma Huateng mentioned just now are not a problem.

And what he wants now is for Ma Huateng to research the FLEX code that belongs to Qingtian.

At this time, Ma Huateng really didn't know what to say, he felt that Fang Chen's idea was a bit fantastical, and he developed the code by himself, which was much more difficult than what Fang Chen said 70 words per piece of information.

70 words, he can also think of a way, for example, send 70 words with four pieces of information, but this is really terrible to develop and code by himself.

"Is it difficult?" Fang Chen suddenly asked.

Ma Huateng's head was like pounding garlic, and he nodded again and again, it was difficult to get to his grandmother's house soon.

"But I don't think it's difficult, although the POCSAG code is good, but after all, the technology of 1976, in the past two decades, the world communications industry has changed dramatically, all kinds of new research papers, the results can be described as endless, there must be some good solutions and technologies, all you need is to integrate them and develop a workable set of codes. Fang Chen said seriously.

Hearing this, Ma Huateng couldn't help but squint his eyes, and a flash of inspiration flashed in his mind, although he resisted developing the code by himself, but what Fang Chen said was really right, no matter how powerful the POCSAG code was, it was also a technology in 1976, and it has long been outdated and backward in the modern era of increasingly innovative technology.

Looking at Ma Huateng's appearance, Fang Chen sat up and said faintly: "You don't want the company, as well as your technology, to only stay at the stage of imitation and copycat, right?"

Ma Huateng swallowed and foamed at the mouth and did not speak, but he actually felt that there was nothing wrong with copycat imitation.

"I know it's very difficult, for you, for the company, it's a huge challenge, but as a high-tech company, Qingtian must have its own technology, or unique skills, can contribute to Huaxia and the world, if you can't do it, then I can only say that you are not suitable for Qingtian, Qingtian is destined to be a brave company, in the pursuit of technology, improve the strength of Huaxia's science and technology, Qingtian has no regrets!" Fang Chen stared at Ma Huateng and said word by word.

Fang Chen's words were like a heavy hammer, hitting Ma Huateng's heart fiercely.

For a while, Ma Huateng was struck by lightning and didn't know what to say.

Fang Chen turned his head to look out the window, anyway, he was unwilling to be an imitator, following behind other people's butts, picking up the leftovers of other people's food, otherwise, he would be too unsuccessful to be reborn.

And as Taizu said, prosperity cannot be relied on introduction, and science has never been shortcut!

Hard research and development, hard work, this is the only way for DynaSky, and DynaSky must have its own technology!
