"Lin, I think we might develop a new way of transmitting data between the portable device and the computer," Moros put down the tablet in his hand and said to Lin Zheng in distress: "Now this method of using infrared rays to transmit data is too inconvenient. ”

"Oh? What are your thoughts? Lin Zheng put down the book in his hand and asked Moros with a smile.

Since he came to the United States, according to his previous promise to Moros, of course Lin Zheng has to take this troublesome little girl with him, but fortunately, this little girl is not troublesome, as long as Lin Zheng keeps himself by his side, Lin Zheng should be busy with whatever he wants.

For the distress of Moros, Lin Zheng naturally knows that the infrared transmission system is the most widely used transmission / receiving device for many mobile devices today, from high-end function calculators to mobile phones, personal portable electronic assistant products and other devices can be seen in the infrared transmission equipment, and the Apple Newton tablet computer that Molos is now using is modified by itself and has applied the micro linux system improved by Molos, which also has an infrared transmission and reception system.

But the limitations of infrared are very large, to put it simply, this thing is a directional transmission system, and the maximum allowable deviation angle between two infrared sen/receive devices is very small, and omnidirectional transmission cannot be realized, which is too cumbersome for many applications.

"I think we can develop a short-range wireless communication technology that can be easily applied to mobile phones, PDAs, laptops and even wireless headphones, and can easily exchange data between these devices. What do you think of this idea? Moros tilted her head and asked Lin Zheng expectantly, "I think the market prospect of this thing should be very good." ”

Isn't it just good, it's simply an inseparable part of the personal portable mobility system in the future, right? Lin Zheng has nothing left in his heart except shock: according to this girl's description, the technology she said is Bluetooth technology at all, is it good?

"Hey. Are you talking? After waiting for a while, she didn't wait for Lin Zheng's reply, and Moros, who was looking down and thinking about how to deal with it, was a little unhappy, and what made her even more unhappy was that she originally thought that Lin Zheng was thinking about her words, but when she looked up, she found that Lin Zheng was in a daze, and the little girl became more and more unhappy!

A thirteen or fourteen-year-old girl is a sensitive girl who not only craves recognition. I hope that the whole world will pay attention to me, but now that my adoptive father has shown such a careless attitude, how can the little girl accept it? In an instant, his eyes turned red. His big eyes were full of tears, his small mouth was deflated, and he was about to cry out after two snorts.

"Huh? Oh...... Hey? What happened to you? In less than a second, Lin Zheng's mood experienced three changes: dazed, calm and surprised, and in the end. Look at Moros's little face that almost cried. Boss Lin was a little at a loss: Why did you cry just now? Fortunately, his 20-year-old body contained a soul in his forties and fifties, and his reaction was not slow at all, and after a short period of shock, he immediately reacted to what the problem was, and touched Moros's head with a smile: "Silly girl, what do you think?" I'm thinking about this thing you said, I seem to have heard it somewhere. ”

"Really?" Hearing Lin Zheng say that he was not perfunctory, the little girl stopped crying, and her big eyes were filled with tears. He snorted and asked Lin Zheng.

"Absolutely!" Lin Zheng nodded with great affirmation, and at the same time comforted himself in his heart: Bluetooth technology. I have not only heard of it, but also used it, of course, I am not perfunctory to this little girl.

But this guy definitely underestimated the sensitive Cheng dù of the girl in front of him, and the little girl asked reluctantly: "Then where did you hear about it?" ”

"I'm ...... You make me think about it...... Well, come to think of it, I heard them talk about it after the last time I negotiated with Ericsson, and it seems that they started working on the technology you mentioned in '94. ”

"They started working on this technology in '94?" Thinking that this idea was his original Morosis, his eyes suddenly darkened: "Then I guess they even applied for a patent, right?" I thought ......"

"That's not true, listen to what they mean, it seems that there are too many technical links involved in this research, and they can't handle it with Ericsson, they have encountered too many technical difficulties, and there is little progress, so they are ready to seek partners externally." At the same time, Lin Zheng began to recall the development process of Bluetooth technology, Ericsson, which began to study Bluetooth transmission technology in 1994, encountered unimaginable difficulties in the research process, which was so great that it would have to stop if it did not seek the help of its partners.

Ericsson, who had intended to monopolize the technology, had to bring in new partners after a painful trade-off, and finally contacted a number of device manufacturers in 1997, which sparked their interest, and Bluetooth technology was on the right track...... In other words, the current Ericsson company has not actually made much progress in Bluetooth technology at all?

"Really?" After confirming that Lin Zheng was indeed not perfunctory, but thinking about his words very seriously, the little girl suddenly burst into tears and smiled, snorted, and a bright smile bloomed on her smiling face: "Then can we cooperate with them on this thing?" ”

Partnering with Ericsson on Bluetooth technology? This question, which Lin Zheng had never thought about before, was placed in front of Lin Zheng like this, so that Lin Zheng had to start thinking seriously: Do you want to cooperate with Ericsson? Or rather...... Is Ericsson, a mess with strong technical strength, able to look up to Lianchuang Technology?

Don't look at the "Bluetooth" this little thing is inconspicuous, the future generations need to buy a Bluetooth headset for thirty or forty dollars, but if anyone thinks that this thing has no technical content, it is a big mistake, look at the development of Bluetooth technology, the Bluetooth special interest group initiated by Ericsson has encompassed Ericsson, Nokia, Toshiba, IBM and Intel Corporation, the world's top telecommunications and electronics, software and chip developers, and the giant Intel company of semiconductor chips is responsible for the development of semiconductor chips and transmission software, Ericsson is responsible for the development of radio frequency technology and mobile phone application software, IBM and Toshiba are responsible for the development of notebook interface specifications, and the five giants have joined forces with the sole purpose of enabling Bluetooth technology to become the wireless communication standard of the future.

But that's not the end, in the second half of 1999, Microsoft, Motorola, Samsung, Lucent also participated, and the five companies of the Bluetooth task force jointly initiated the establishment of the Bluetooth technology promotion organization, so far, "Bluetooth" has finally become the climate.

Take a look at these companies involved in the research and development of Bluetooth technology, any one of them is in their own field like a bison rampage no one dares to stop the master, Lianchuang Technology is also a big company in China, but in front of these giants is really not enough, people will not look at themselves at all, want to mix in it?

It's hard!

"That's it......" Hearing Lin Zheng's explanation, Moros was a little disappointed: "Is there no other way?" ”

"Other ways ......" thought for a long time, Lin Zheng finally shook his head with a wry smile, he didn't have the idea of Bluetooth technology at the beginning, but he didn't think it was a good idea to think about it, strictly speaking, Bluetooth technology does not require much investment, but the problem is that there are too many technical difficulties involved, chips, frequencies, software, matching...... With the current R&D strength of Lianchuang Technology, it may be possible to solve one or two of the technical difficulties that are not so difficult, but there is no place that these giants can not ignore, cannot be bypassed, and have to find their own cooperation.

Boss Lin was not arrogant enough to think that after he was reborn, the earth should revolve around him, and patted her head with a smile: "After they get it, let's just buy it and use it, well, by the way, isn't the Wi-Fi technology we are developing now also able to achieve your requirements on a certain number of degrees?" If this technology is further developed, it is not impossible to realize the functions of the short-range wireless communication technology that Ericsson is developing. ”

As early as the development of wireless LAN technology, it has begun to develop Wi-Fi wireless fidelity technology, Lianchuang Technology, has made considerable progress in Wi-Fi technology, although Wi-Fi also has its own limitations, but in Lin Zheng's view, Wi-Fi application is not necessarily worse than Bluetooth technology, perhaps more people just use Wi-Fi only for the purpose of wireless Internet access, in fact, Wi-Fi can achieve many functions, multiple mobile phones, Personal handheld computers and laptops can borrow Wi-Fi technology to easily achieve free networking, compared with Bluetooth, one of the biggest advantages of Wi-Fi is the huge programmability and upgrade potential, with the help of network and Wi-Fi and supporting software, we can even operate electronic devices from a distance of thousands of miles, whether it is one-to-many and many-to-many, or remote operation, these are not available in Bluetooth, compared to the trouble to engage in Bluetooth, On the contrary, Lin Zheng thinks that Moros can think more about Wi-Fi technology.

"That's right!" Lin Zheng's words reminded her, and the little girl who was extremely depressed just now suddenly became excited: "Why did I forget our Wi-Fi technology?" No, I'll go! ”

Looking at Moros, who was hurrying away, Lin Zheng shook his head with a smile. (To be continued......)
