Coquettish Rebirth

.

I don't know if I don't contact the spn. I was shocked when I contacted. In February of 98, Ericsson had already contacted 2 manufacturers for cooperation. The three manufacturers were Toshiba, BM and Intel.With the presence of these three houses, the whole class will be upgraded as the old man said yyng!Suddenly, there is a feeling that the industry giants formed a small group to form a patent pool!

However, after Jia Hongjian contacted Ericsson with a consortium such as ms plus Huaxia Hi-Tech, and expressed the intention of these two manufacturers to join, within a full week, a manufacturer like Ericsson They didn't call at all, and it was a week later that they sent a message lightly, saying that the grade and technical level of ms and Huaxia Hi-Tech might not meet the standards for joining the bluetooth technology team of several of their manufacturers for the time being. According to the standard of the group, manufacturers like Nokia may enter...

Although I originally considered that the weight on my side might be a bit light, but when the other party said so clearly, the other party didn't even give me a chance to meet, so I wrote it so clearly on an official letter by fax. This is really a bit of a slap in the face!

After receiving such a fax, Jia Hongjian's face turned green at that time. He has grown up so much, and he has never been slapped in the face like this before!Just when Jia Hongjian was losing face, he heard the old man Olsen lose his temper. This old man was obviously more arrogant than Jia Hongjian. If Jia Hongjian couldn't bear it, could he bear it?At that time, the old man lost his temper, "Isn't it just a broken Bluetooth? What's the big deal. It's something similar to 24ghz, what's the point? They can be applied to earphones, just as if we can't do it? Develop a In 5 years, we can also do 24ghz in the headset!"

Hearing what the old man said, Jia Hongjian's attention was attracted at that time, "What? We can also make this into earphones? Can it be made into wired earphones?" I'm familiar with it, but I think the high-end earphones for mobile phones are bluetooth earphones. Have you ever heard of any 24ghz earphones? [

But at this moment, I only heard the old man say. "What's wrong? It doesn't matter if it's music or something. To put it bluntly, isn't it just a wire signal? As long as the information capacity we transmit is large enough, it can be transmitted! Even if it is large enough, let alone music, even video is still transmitted by wire! Our 24ghz has an overall transmission capacity of 2mbps, which is 256kb per second if calculated as the capacity standard on a computer. Can’t a piece of music be transmitted at such a rate?”

Hey.According to what the old man said, the speed of 2mbps is the speed of Little B.It is not yyng with the big b standard on the computer standard.This small b standard is basically used in places other than computer storage, such as the telecommunications network of later generations, which are all in small b units!So this 2mbps speed is also the speed of the 2 megabit broadband of Telecom SL in later generations!This 2 megabytes of broadband, when just downloading, is indeed a speed of more than 200 kb, which is the speed of a big b. Such a speed is really not to mention mp3, it is enough to watch videos such as Tudou Youku online !

With the broadband speed of two megabytes, watching ultra-clear videos on the so-called Youku website is 720p, and the bit rate is only 1mbps1!So at this 2mbps speed, you can really watch 720p online streaming video!In this way, the 24ghz technology in the future can really last for 10 years without being outdated!After thinking of this, Jia Hongjian almost wanted to hug and kiss old man Olsen. How could this old man develop such amazing technology?It sounds like it’s much better than Bluetooth, at least it’s not a disadvantage, right?

"Hey, old man, what's the difference between Bluetooth technology and our technology?" Jia Hongjian asked casually subconsciously. "How do I know the difference? I haven't read their technical documents... But I guess it's basically a thing that uses the 24ghz frequency band. After all, I researched and researched, and finally the 24ghz frequency band is more suitable. To put it bluntly, at best, they are developing at the same pace as our 24GHz technology, which is basically the same thing..." The old man replied.

Hearing what the old man said, Jia Hongjian thought for a while, that's right, a giant developed bluetooth, and this bluetooth stuff has been used more in earphones in later generations, isn't it?At most, it is useful for the interconnection of smartphones, what else is there?At most, such a bluetooth stuff does not need a receiver!But something like a receiver can be made built-in!In general, everyone started together. What is the decisive and revolutionary performance gap?Their group of people are giants in research and development, and Huaxia Hi-Tech and MS are considered regional potential stocks, so they can't develop their own things?Is their 24ghz worse than bluetooth?

Ericsson, bm, and Intel felt that Huaxia Hi-Tech was inferior to Nokia, and that Huaxia Hi-Tech Jia Hongjian was not good enough, so Jia Hongjian and the others would make something to compete with their bluetooth!Let everyone see what level he is Jia Hongjian, Huaxia Hi-Tech, and ms!

So at this point, Jia Hongjian immediately made a decision! "Okay, Ken, let's make this 24ghz, I will give you 3 months to develop, can you make it?" "No problem, I can almost find a place to try it out in a month, and I can directly tape out trial production in 3 months Well, when 3 months have passed, we can directly mass-produce! Let Ericsson bastards see what level we are! Bastards, they actually found bm and they started to look down on us..."

The old man was obviously irritated by the stimulation, so after the big one and the small one were decided, he began to quickly advance to the product design.The 24ghz band designed by the old man is a full-duplex mode transmission, and the anti-interference ability is much stronger than the previous 27mhz line mode.And because of the super anti-interference ability, the receiving distance of this product can be up to about 10 meters!This basically means that if you move the mouse in another room, the computer can also sense it!

Moreover, the 24ghz signal of this line does not use a straight-line receiving mode similar to infrared rays, but a line communication protocol that is very similar to a line network like WF, so even if it is separated by a wall, the signal weakening is not huge. Of course, If there is a distance of seven or eight meters and there is a reinforced concrete wall, the signal is indeed very poor.But as long as the distance is short, as long as it is in a residential building, it can be said that the transmission capacity of this line signal is 27 times that of 400mhz!

When the old man was first in e.The prototype of this product has been basically developed.This is next to work.Jia Hongjian offered the old man a very disgusting proposal, "Old man, if they want to build Bluetooth, they must want to build a patent pool, and then several companies will work together to form the Bluetooth standard. In the end, they will charge licensing fees or something. So since they see Not us. We have to prove our ability again. I think we should simply open up our communication protocol and directly make our 24ghz mode a real free mode! Let them see who Ericsson, bm and Intel are The technology first dominates the market! By the way. On a free basis, we only need to make one request. We don’t charge money, but we need the other party to print our ms and Huaxia Hi-Tech names on the products! It’s like Dolby Laboratories , Their expression will be printed on many film and television works yyng!"

That's right, Jia Hongjian is now barefoot and not afraid to wear shoes!What are the three manufacturers doing for Bluetooth to make money?Okay, I will give the communication protocol for free first!See how you charge for Bluetooth in the future!No wonder the popularization of Bluetooth products in later generations is relatively slow. Emotions are the reason why these three manufacturers collect money behind the scenes!And this 24ghz mouse with various wires is a hot seller. Maybe it’s because the old man in history has been slapped like this once, and he just made the patent public and let the world use it casually!

And on this point, Jia Hongjian obviously had a bad temper with Olsen in history. Since they can't enter the Bluetooth camp, they will be in their own camp, and then the disgusting Bluetooth can't make a penny!Let these sub-tycoons directly and hugely invest in nothing!Who told you giants not to take us to play?If you don't play with us, we'll make trouble for you!

Originally this stuff was developed by the old man, and the band frequency used is almost a free frequency around the world between 2405ghz and 2485ghz. The old man chose the best one that no one is using now, which is less likely to be interfered, and consumes more energy. After the low band, go directly to register and announce the band one by one!In this way, once it is settled first, the Bluetooth standard cannot choose the same frequency!This is a big battle with the GPS of later generations yyng

In later generations, after the United States developed GPS, taking advantage of the fact that no one else in the world had it, of course they chose the band with the least interference and the best effect.Next, Europe said that they wanted to get their Galileo global positioning system.At that time, China was also interested in this stuff, so it contacted Europe, and it turned out that Europe was also willing to let China join.Later, the two groups of people colluded together and wanted to come up with a Galileo system against American GPS.

In the end, I don’t know what happened. The boss of this European has a serious mind, so he regards China as a cash machine. China is not allowed to participate in technology research, and China is allowed to pay. It is said that China paid hundreds of millions of euros in the end, but the technology that can be encountered It's not as good as India, which doesn't spend much money!At this moment, China became very popular, so I just quit the job, and then I got my own Beidou system when I returned home.Originally, China’s Beidou system was developed later than Europe’s Galileo, but I don’t know whether Europe was too fussy or China was too fast. Anyway, China launched the satellite first.Then let’s launch it up first, and occupy the frequency reserved by Galileo in Europe!

That's right, in this frequency band, GPS is the best, and the next is the second best, and the second best choice, and the division of this frequency in the world, that is, whoever uses it first will get it.So when Europe is arguing about going to court with China, the Chinese satellites here have practically used this band!As for the band on this satellite and the 24GHz band yyng, whoever uses it first will be more expensive. Jia Hongjian and the others snatch the good band first. (to be continued...)
