"→" is a great novel to read.

The communication guard walked in quickly, and saw Li Yunlong and Zhao Gang talking so freely, they didn't know whether to say it or not, they looked hesitant, and they didn't know whether to say it or not!

Seeing this, Li Yunlong looked up and said, "If you have anything to say, just say it, don't have to swallow it!" ”

"Yes!" The communication guard said loudly: "Report to the brigade commander, political commissar, the latest report from the Shanghai Research Institute, a major successful preliminary study has been completed, please go and inspect and watch!" ”

Shanghai Research Institute is a research institute composed of talent associations.

It can be said that the rapid development of commerce, science and technology, industry and so on in the Chinese mainland is inseparable from the Shanghai Research Institute, and the research success of this research institute is to make the world stunned, amazed, and surrendered to the amazing invention research.

At that time, the scientific researchers of the Shanghai Research Institute knew that these technologies and advanced theories were inseparable from one person, that is, Li Yunlong!

Without Li Yunlong, there would be no Shanghai Research Institute, and there would be no various advanced research results of the Shanghai Research Institute.

When Li Yunlong heard this, he looked at Zhao Gang next to him, and said slowly: "Old Zhao, it seems that I have caught up with a good time, let's go, go and see what the situation is!" ”

"Okay!"

Immediately, Li Yunlong, Zhao Gang and others started to go from the headquarters of the Shanghai Iron and Blood Lion Army*

Shanghai Research Institute is located in the most prosperous section of Shanghai.

In order to ensure the safety of the Shanghai Research Institute, a whole predator with a full reinforced battalion is stationed in the research institute to strictly prevent people from entering and exiting, and to ensure the safety of the research personnel of the research institute and the safety of research success!

After several checkpoints, Li Yunlong, Zhao Gang and others walked into the center of the research institute, at this time, an old man wearing a white coat and white hair saw Li Yunlong walk in, and greeted him affectionately and very excitedly: "Brigade commander, our research results have been successful!" ”

This gray-haired old man is the person in charge and leader of this mobile phone project, his name is Fang Yu, and he is an expert in telecommunications!

Prior to this, Li Yunlong passed the relevant research materials of computers and mobile phones to the Shanghai Research Institute, so that they could conduct research on computers and mobile phones, so Fang Yu took the lead in the development of **,

After the efforts of not writing and many experiments, now the mobile phone is finally successfully researched! This made Fang Yu very excited and happy, because such high-tech products are made according to the theory and related development procedures provided by Li Yunlong!

Therefore, as the leader of the research and development of the mobile phone project, Fang admired the theories and knowledge provided by Li Yunlong very much, which was simply an astonishing theory, which made people admire.

Fang Yu looked at Li Yunlong excitedly and said, "Brigade commander, it's successful, our mobile phone has been successfully developed!" ”

Mobile phones are much simpler than computers, so they are relatively quick to develop!

"Great!" Li Yunlong was also very happy when he heard it.

Immediately, Fang Yu and several scientists held two pitch-black bricks in their hands, these bricks are about 30cm long and 10cm wide A rectangular brick, there are a total of 10 button number keys on the bricks, as well as up and down left and right buttons, confirmation keys, and dial keys and hang up keys for telephones.

This piece of the head weighs about 2 kilograms, which is very heavy!

Li Yunlong looked at the two mobile phones in front of him, and the impact on him was the same as that of the big brother in the eighties and nineties, and because of the limitations of materials and technology, the weight and size of this big brother mobile phone are very large.

"Big brother's mobile phone, it looks like it's really the same!" Li Yunlong said with a slight smile: "This mobile phone is almost the same as I imagined!" ”

The mobile phone developed by this generation has a very simple function, which can only make calls, and the way it is pre-allocated is adopted.

Because there is no mobile phone card and network in this era, and there is no satellite, each mobile phone is pre-set with a number, as long as you use other mobile phones to paging and dial this number, then you can get through!

The big brother mobile phone that Fang Yu was holding in his hand was full of tears, and he was very excited to introduce: "This mobile phone is our first generation of products, which can make calls, and the function is relatively simple, that is, to make calls and receive calls!" Because it is a first-generation product, this radio communication may be affected and the call quality may be a little problematic! ”

"But we're improving the phone right now, along with the ideas you provided.

Generally speaking, the communication between mobile phones does not require satellite transmission, and ordinary mobile phone communication is radio communication. Satellite transmission is only required for satellite phones.

Radiocommunication is a communication method that modulates the sound, text, data, images and other electrical signals that need to be transmitted on radio waves to each other through space and the ground, and uses radio-magnetic waves to transmit information in space. A satellite phone is a satellite relay intercom that transmits information based on a satellite communication system.

So now, even if there is no satellite, it is still possible to make a general call, provided that there is a signal.

Zhao Gang, Anthocyanin, Hua Mulan and others all stared at the black in front of them with wide eyes, and it was hard to believe that this black turning head could still talk!
