"Brigadier Commander, can this thing talk?" Anthocyanin's eyes were full of incredulity: "He doesn't need a phone line to talk?" ”

"yes, that's amazing!" Hua Mulan was also very curious: "It's really unimaginable!" ”

Fang Yu said with a smile: "Hahaha, your expression is the same as when I first saw the research on this topic, but according to the theory and research process provided by the brigade commander, we have really created this kind of mobile phone that can talk remotely and does not need a phone line!" ”

"Hahaha, the technology will be more advanced in the future!" Li Yunlong said very confidently: "In the future, mobile phones can also access the Internet, touch control, and have all kinds of video games...... You can use AR to visually control ......"

Li Yunlong kept talking about the development of mobile phones in the future, and everyone such as anthocyanin, Fang Yu, Hua Mulan and others were stunned for a while, although many of them couldn't understand it, but now they feel unclear.

Looking at everyone's stunned and confused expressions, Li Yunlong smiled faintly and said: "Okay, let's talk about these later, I guess I don't understand it with you now, let's take a look at this mobile phone!" ”

The function of the first generation of mobile phones developed by research and manufacturing is very simple, it can only make calls, and only after entering a specific number can you get through.

Now there are two telephones, the first with a simple number of 000000 and the second with a 111111 number!

Li Yunlong took over the big brother's mobile phone with the number 000000, and then began to dial the phone and enter the 111111, and then a beeping sound could be heard.

In addition, the big brother mobile phone numbered 111111 is in Zhao Gang's hands.

When Zhao Gang pressed the answer button, he immediately started talking to Li Yunlong: "Hey, hello, I'm Zhao Gang, the political commissar of the Eighth Route Army's iron-blooded lion army!" ”

As Zhao Gang's voice fell, it was transmitted to Li Yunlong's mobile phone a moment later!

The quality of the call is still okay, very clear, although a little noisy, but still very clear to hear the other party's voice.

"His grandmother's, Lao Zhao, you still have an official relationship with me, hahaha!" As soon as Li Yunlong heard that this mobile phone could really make calls, he immediately became excited: "Our iron-blooded lion army finally has a mobile phone!" ”

"Yes, Lao Li, you can talk on the spot in the future!" Zhao Gang held the big brother in his hand, and it was self-evident that he was excited.

"In the future, we won't need to use telegram for calls, and it will be safe in real time!" Li Yunlong said: "This is of great significance to the development of our troops!" ”

The telegrams sent by the radio station may be intercepted and revealed, and it is also very easy to be sabotaged and interfered with, because the radio has been around for a long time, and there are many anti-radio stations and radio reconnaissance machines, so there is no security.

However, this mobile phone has just been invented, which can not only make real-time calls, but also be very safe and confidential, avoiding the leakage of information and calls.

The call between Li Yunlong and Zhao Gang can be said to be the call of the century, because it represents the emergence and germination of high-tech products such as mobile phones.

After the two finished talking, Anthocyanin, Hua Mulan and others were very curious about the two big brothers' mobile phones, and then they all tried to talk!

Fang Yu was very satisfied with the effect of such a call, but after hesitating for a moment, he looked at Li Yunlong and said: "Brigade commander, there is still a problem, that is, the distance of this mobile phone is limited, because the communication telegram will be weakened due to the increase or decrease of distance, and in the end, the mobile phone will not be able to talk!" ”

It's very easy to keep calls between mobile phones.

Since radio waves weaken after traveling through the air for a period of time, relay stations are needed to strengthen the signal during long-distance transmission.

When Li Yunlong heard this, he immediately said: "This method is easy to solve.

"Relay towers?" Fang Yu muttered to himself: "This method is good, brigade commander, you are simply a genius!" That's amazing! ”

Fang Yu didn't expect that Li Yunlong, a brave and warlike soldier, could have such profound scientific attainments and skills, which is simply incredible!

"It's amazing, this black brick can really talk!"

"It's amazing, it's so much more convenient than a hand-cranked phone, it's really amazing!"

Anthocyanin and Hua Mulan feel very incredible and excited that such a big brother's mobile phone can talk!

Under the influence of Li Yunlong, it was researched by the Shanghai Research Institute, which is definitely an invention that shocked the world!
