To tear up the agreement at will, it would have to have this ability, but for Niu Guo, they have no such ability.

After leaving Niu, Han has other countries to choose from. No other countries have it. Qin Guan also has a weapon cemetery. Advanced materials can be exchanged at any time. Therefore, the people of Niu have to tear up the agreement, Qin Guan Don't care.

But now, if Niu Guoren tears up the agreement, Han's corresponding retaliation will also be fierce, but Niu Guoren can't bear it.

Niu Guoren watched Qin Guan making a call in surprise, his eyes fell on his phone, why is the sound quality so clear? What mobile phone is this?

With the continuous development of Hanxin Technology's technology, Han Guo finally has sufficient technical reserves to carry out other research.

Therefore, Qin Guan found a new direction for Ni Gong and others, that is, mobile phones.

Mobile phones are divided into several generations. The first generation of mobile phones, which is the most common analog technology, is now popular in the Western world. The second generation is GSM technology. Qin Guan didn’t care about these technologies and directly targeted them. It is the CDMA technology in the second generation. This technology has the best development prospects and can be transitioned to the third generation mobile phones at any time.

Now, Hanxin Technology has developed rapidly, has overcome related technologies and registered a large number of patents. It can be said that any company who wants to use mobile communication technology in the future will definitely not be able to bypass Hanxin Technology’s technical barriers.

At the same time, mobile communication technology is slowly becoming practical.

They have to conduct tests, so not only on the university campus of Huating, they have also built several base stations in other cities to conduct long-distance data transmission tests to see how effective they are.

It just so happens that Hao Kyung is also a test site for mobile phones, so Qin Guan's mobile phone can be used.

Although mobile phones in the 2G era are obviously much smaller in size, they are technology from the 1990s. Let alone the battery, there is really no suitable battery for it.

This mobile phone, like Motorola, uses 6 cylindrical nickel-cadmium batteries to form a battery pack with an output voltage of 7.5V. This set of batteries determines that the phone at hand is huge, as big as a brick.

At the same time, another disadvantage of this battery is that it takes nearly 10 hours to fully charge, which is simply unbearable.

No way, in this era, there is only this kind of battery, which is full of shortcomings, the battery capacity is low, and the lifespan is also very short. If it is used every day for 500 times, it will be scrapped for at most two years.

Moreover, what is even more unbearable is its memory effect. It must be fully charged each time it is charged, and it can be used again after each use. Otherwise, the battery capacity will be greatly reduced.

(One more thing, I feel that now, the idea that the battery needs to be fully charged for 12 hours for the first use is from the age of nickel-cadmium batteries. Unfortunately, many people still regard it as a classic.)

Moreover, cadmium itself is toxic, this kind of battery is really not easy to use.

However, the current Hanxin Technology Company cannot be involved in all aspects, such as the battery, they really have not invested in research and can only use what is available on the market.

This dragged on until 1989, when the nickel-metal hydride battery came out. The cost of this battery technology did not increase much than the nickel-chromium battery, but the battery capacity has been significantly improved.

Compared with nickel-cadmium batteries, nickel-metal hydride batteries are lighter, thinner, non-toxic and have greater energy density. At the same time, the memory effect of the battery is also reduced a lot, which is a huge leap forward.

Therefore, the current Qin Guan had to endure the defect of this big man, and waited for a few more years.

In later generations, after the advent of lithium batteries, they are truly suitable rechargeable batteries. Even electric vehicles are made of tens of thousands of 18650 batteries in series and parallel.

Now, holding the mobile phone in his hand, after making these two calls, the Niu people in front of him will wilt. They still protest and want to tear up the agreement?

Let you kneel down and beg for mercy in minutes.

"Mr. Qin, your call is really enviable. What kind of call is this?" Niu Guoren saw a bad dish, but now, if they directly let them admit their mistakes, they would be embarrassed. Qin Guantao was close, and then talk about it.

Qin Guan holds the phone in his hand to attract them. After all, the overall domestic economy is not high, and few mobile phones can be used. Therefore, after the development, the idea of ​​selling mobile phones is the right thing to do. way. Especially Western countries.

Now, hearing their question, Qin Guan said: "This is a mobile phone we developed."

"It looks the same as Motorola's." The other party said.

"What's the same? Open your eyes and see." Qin Guan couldn't help but feel a little angry: "Our phone uses digital technology, do you understand? Our signal is sent out after encoding, and there is no possibility of eavesdropping. One of our base stations can accommodate many telephones at the same time. Motorola’s products are pediatrics here."

What is Motorola? They are outdated a long time ago, and their phones are obsolete technology.

In the era of digital technology, the right way is to code and transmit data.

After speaking, Qin Guan put down the phone in his hand and placed it in front of everyone: "This phone is another major project since our breakthrough in electronic computer technology. It is now in the early stage of promotion. If there is a country Willing to cooperate and introduce our mobile communication technology, now it can be promoted at low cost, and the price will be higher in the future, how about it, do you want to try?

Several people were directly related to the communications industry, but they just said that they were frozen, and now they can ease it up. One of the leaders said: "Then this phone, can we use it for a while?"

It's easy to use or not, you'll know after using it.

Qin nodded his head and put down the phone: "Let's use it for a week. The phone bill goes to our company's account. By the way, where did we talk about it?"

"Oh, talking about giving us this phone." The man in the lead answered the phone and said to Qin Guan.

"No, it's the previous one, you said, you want to tear up all the contracts?"

"No, no, we just talk casually, can't take it seriously, Qin, our contract, let's follow the previous contract."

"What about the source code of the program we requested?" Qin Guan asked.

Can you give this? The other party frowned, picked up Qin Guan's phone, and said, "We have to make a call to China, and ask for instructions."
