Chapter 1717 (1/2)

Qin Feng refused very firmly.

”Boss, although you are a wise boss, you have to give me an explanation, otherwise I will never agree!” Melissa said angrily.

However, she also knew that Qin Feng was the boss after all. In order to avoid the deadlock between the two sides, she flattered Qin Feng.

Women are as careful as hair and are always good at dealing with all kinds of male bosses.

Qin Feng skimmed his mouth.

”Because 3G is not the future!” Qin Feng said faintly.

”3G is not the future? It's not popular yet. You say it's not the future! ” Melissa exclaimed.

”You should know that in 1985, Qualcomm developed a new technology called” CDMA ”by using the” spread spectrum technology ”lifted by the military. This CDMA is today's 3G! ” Qin Feng said.

The so-called spread spectrum technology actually comes from earlier sources.

In 1940, American actress Heidi Rama proposed a technical concept of spectrum, the so-called spread spectrum technology, which is a communication technology that disperses the spectrum of transmitted signals to a wider bandwidth than its original bandwidth, which is commonly used in the field of wireless communication.

In March 1938 * * officially invaded Austria. Heidi Rama, who lived in Austria, fled to London to stay away from her failed marriage and many * * friends. By the way, she also brought the ”military secrets” of * * wireless communication to the allies. These secrets are mainly ”command guidance” systems based on radio secure communication, which are used to automatically control weapons and accurately attack targets. However, in order to prevent radio commands from being stolen by the enemy, a series of radio communication security technologies need to be developed.

At first, because of her status as an actor and her ex husband's composer, Heidi was able to contact many senior * * officials. Although she is an actress, she is well-educated and knows that this technology is of great value.

So when she was in Austria, she secretly learned her technology. Then return to the motherland and conduct research. Finally, in August 1942, she got a patent from the United States. In the U.S. Patent Office, such a patent was once sealed: the patent for ”secure communication system” with patent No. 2292387. The patent was passed on August 11, 1942 and applied on June 10, 1941. Spread spectrum technology (spread spectrum technology). Filed on the website of the national patent office, the technology patent was originally used for military purposes.

However, at first, this technology was used to deal with the radio wave interference or anti eavesdropping military communication system of * * Germany, so its main function was to be used in the military.

Naturally, with the end of World War II, this technology was dusty.

Until 1985, after the military unsealed. Qualcomm saw the value. Then, there is the 3G network.

Qualcomm, by virtue of this, has grown from an unknown company to a world giant.

It can be said that war is the best catalyst for science and technology.

Among the many dusty technologies in the United States, we never know how many can change the future world.

”Boss, you are familiar with this history. You should be an archaeologist.” Melissa teased.

Qin Feng sent a white eye.

”Don't you understand what I mean! 3G is a technology that came out in 1985. Why hasn't it been popularized yet? ” Qin Feng asked.

”Because the conditions were not allowed!” Melissa said.

”Why are conditions not allowed?” Qin Feng asked.

”Because there was no mobile device to use 3G network.” Melissa said, ”although the technology exists, there are no relevant application conditions. Therefore, it can't be used. Now, the popularity of mobile phones and the growing maturity of mobile phone chips have given its market. That's why we use it. We need joint development. I have settled with the three major operators in the United States. We have invested to jointly build a 3G signal tower, with half of the future profits. ”
