As soon as these words came out, everyone stared at Fang Chen, this is definitely a problem, after all, even if they have created a more technologically advanced mobile communication system, but in the final analysis, it is also based on Qualcomm's technology.

"That's right, these are Qualcomm technologies, but we can develop our own technologies to exchange patents with Qualcomm!" Fang Chen's eyes flashed with a hint of cunning.

Code division multiple access technology not only involves 2.5G network, but also involves 3G network, its predecessor is actually the American amphibious star, Hedy Lamarr in World War II research spread spectrum technology, is the United States military technology, and Qualcomm is based on spread spectrum technology research code division multiple access technology.

And it is worth mentioning that Bluetooth and WIFI technology are derived from Hedy Lamarr's spread spectrum technology, which has also been inducted into the American Inventors Hall of Fame, and is admired by future generations along with Edison, Watt, Bell, Tesla and others.

"I envision a new generation of mobile communication systems with low-cost short-range wireless connectivity that can establish communication environments for both fixed and mobile devices. ”

"And I don't know if you have noticed the information superhighway plan proposed by the Democratic presidential candidate of the United States, Clinton and his partner Albert Gore, which envisages a high-speed, broadband integrated information highway based on optical fiber trunk lines, supplemented by microwave and coaxial cable distribution systems, so that high-speed transmission of radio, television, telephone, fax, data and other information, which will greatly change the way of life of human beings, not just computers, one day mobile phones can also be connected to such a network through base stations. ”

"Even in the future, we can convert the wired network signal of the home into a wireless signal instead of a base station, and connect the mobile phone to the Internet through the wireless signal at home. ”

Everyone looked at Fang Chen with a confused expression, what the hell, how could they have noticed the plan proposed by a US presidential candidate, and it could even be said that they didn't even know which onion Clinton and Albert Gore were.

And judging by the expressions, even Dr. Xiong Lejiu, the two Stanford doctors who returned from the United States not long ago, don't know who Clinton is.

Fang Chen rubbed his nose, he had a feeling of playing the piano with a cow, and the three technologies he just mentioned were familiar to almost everyone in later generations, in fact, they were Bluetooth, WAP and WIFI.

These three technologies are very important for the mobile network of later generations, especially in the era of smart phones, and these three technologies have only been studied one after another after 1996, so now with his support and guidance, Qingtian Communications is still quite promising to be researched.

But as soon as his thoughts turned, he was relieved, if someone below understood in seconds, he was afraid that he would have to wonder if people were reborn like him.

With these three key technologies, he can play the trick of patent exchange with Qualcomm.

Thinking of this, the corners of Fang Chen's mouth couldn't help but show an inexplicable smile, he thought that when the time came, the expression on the face of Qualcomm's chairman, Owen Jacobs, would definitely be wonderful.

You must know that this kind of patent exchange trick has always been what Qualcomm is best at.

In the previous life, Qualcomm stipulated that no matter which company used his patents, not only should he pay patent fees according to the price of 5% to 10% of the hardware, but also need to unconditionally authorize the communication patents he researched to Qualcomm and Chiguoguo's overlord clause free of charge.

However, after the cards are available, how to play them well is another problem, and these three cards are still a little hard enough compared to Qualcomm's code multi-address technology, Fang Chen couldn't help frowning.

At the very least, neither Bluetooth nor WAP has charged royalties, but is free for the world to use, and WIFI, which was tried to be sold to Apple and Dell, by the father of Wi-Fi, was scoffed at and rejected because of the power problem of WIFI.

In the end, the father of WIFI donated the patent rights to the Commonwealth Scientific and Industrial Research Organization of Australia, and its status in Australia is almost equivalent to that of the Chinese Academy of Sciences in China.

The Institute of Electrical and Electronics Engineers (IEEE) has persuaded the Australian Commonwealth Scientific and Industrial Research Organization to give up ownership of the WIFI patent, but the Australian government has rejected it.

What are you kidding, how can the Australian government take the initiative to give up such a chicken that lays golden eggs on WIFI.

It seems that in the face of money, the requirements of American dads are not easy to make.

With this WIFI patent ownership, Australia collects royalties from almost all electrical and telecommunications companies in the world, including Apple, Intel, Lenovo, Dell, Sony, Microsoft, Huawei, etc.

It can be said that every time we buy an electronic device that contains WiFi technology, the price we pay includes the WiFi royalties handed over to the Australian government.

However, it is worth mentioning that Huaxia is not actually using WIFI, but WAPI, a wireless LAN security technology standard independently developed and with independent intellectual property rights.

It is China's first secure access technology standard with independent innovation and intellectual property rights in the field of computer broadband wireless network communication, with a total of more than 4 billion chips with WAPI function shipped globally, and more than 7,000 mobile terminal product models/nearly 600 million units.

However, its underlying protocol still touches the patent rights of WIFI technology.

And for a long time, due to the Ministry of Industry and Information Technology's explicit ban on mobile phones that support the Wi-Fi function from obtaining network access permits in China, foreign brand mobile phones must remove the Wi-Fi module or block the function if they want to enter the mainland market, becoming a castrated version of the mobile phone that many people jokingly call it.

In order to implement WAPI, China and the United States have even held talks at the vice-cabinet level.

At the end of 2003, the General Administration of Quality Supervision, Inspection and Quarantine and the Standardization Administration issued an announcement stating that the WAPI standard would be mandatory from June 1, 2004.

The move was immediately met with resistance from American companies such as Intel and even the US government, which threatened to stop wireless business in China, claiming that Western companies would prefer to adopt their own standards over WAPI standards.

After a lapse of five or six years, WAPI has been unanimously agreed by more than 10 countries such as the United States, the United Kingdom, and France, and will be promoted as an international standard in the form of an independent text, while the Ministry of Industry and Information Technology has issued a policy that when the mobile phone cannot search for WAPI, it can be accessed through Wi-Fi for wireless networking, but pure Wi-Fi mobile phones still cannot be listed such a policy, and the two sides take a step back as the end, which is finally the end of the WIFI and WAPI dispute.

The more he thought about it, the more chaotic his brain became, Fang Chen couldn't help but sigh, it was a little difficult.

There is no way, in the face of a behemoth like Qualcomm, the patent monster, especially in the 2G and 3G eras, wants to challenge its position, or even replace it, this difficulty factor is really too high.

But dreams always have to come true.

After chatting with Xiong Lejiu and them, his specific ideas for Bluetooth, WAP, WIFI and other technologies, Fang Chen suddenly mentioned: "Do you have any clue about the high-speed wireless paging code I mentioned to Ma Huateng before?"

Hearing this, Shen Wei and the others couldn't help but feel their scalps tingle, and even regretted a little, they didn't let Ma Huateng rest at home for ten days and a half a month, but on the fifth day of his return, they kicked him to Russia again and continued to follow up the debugging work of the paging base station.

It's good now, Mr. Fang asked about it, and the pony is not there, so they can only fight the thunder.

Shen Wei laughed twice, "Before Xiaoma left, he had already made contact with professors from some universities in China, but the actual progress should be no, but according to Xiaoma's work report to me, although there are some technical problems, it is not that there is no hope of overcoming them." ”

Fang Chen glanced at Shen Wei expressionlessly, although he was a little disappointed, he could accept it, after all, even if he wanted to make dumplings, he had to make noodles in advance, cut the meat and cut the leeks, take his time, he couldn't be in a hurry.

After a pause, he spoke: "Then let me say two things, this kind of high-speed wireless paging coding should focus on providing the transmission rate, rather than the error check of the code, and the transmission rate can be increased by opening multiple channels." ”

Now, the world's universal, developed by the British General Post Office POCSAG code, the transmission rate is only 512bit/s and 1200bit/s, so the efficiency is relatively low, even according to the rate of 120 0bit/s, a frequency user capacity is about 30,000-40,000, POCSAG code can usually accommodate 2 million users.

Such a number of users is really not enough for tens of millions of users in Huaxia in the future.

The FLEX high-speed paging code developed by Motorola next year has three rates of 1600bit/s, 3200bit/s and 6400bit/s, and the FLEX code is achieved by reusing 1, 2 or 4 1600bit/s communication channels to achieve three rates.

That's why he's confident in creating a high-speed paging code that belongs to DynaSky.

Shen Wei quickly wrote down what Fang Chen said in his notebook.

Seeing this, Fang Chen couldn't help but chuckle, he felt more and more like a product manager today, except for mentioning that the code multi-address was his highlight moment, other times it was like a product manager who randomly asked for requirements, without considering whether he could actually complete it.

Thinking about his words carefully, it was even the same as not saying anything, so Fang Chen was not afraid that these people would spread his words.

There are more people in the world who will put forward their needs, just like there are so many people who can dream, but whether the needs are right or not, whether they can be realized, it depends on the wisdom of the benevolent and the wise, and it can even be said that even if others see these advanced technologies he said, they will not really implement and invest in research and development.

The devil knows whether these technologies can be made, and whether they can be used after they are made, there are too many science and technologies that have been shelved in recent years.

After writing Fang Chen's words, Shen Wei suddenly looked like he wanted to say something, as if he had something to say.
