"Yes, Xu Hui has something to say quickly. My husband has been busy for several days and drank so much today. He needs to rest early, otherwise his body will not be able to bear it!" Wu Yi said.
"My husband has been busy since he came back. Normally, he would be busy until early in the morning. Today is another happy day, so I can finally rest early!" Su Mei continued.
The other three people also told Li Min to rest early.
Ji Ruxue also said: "If you don't want to say it now, how about we wait until tomorrow? There's no rush now."
Xu Hui then said: "Okay, okay, I'll say it, I'll say it! I'll say it now!"
Everyone was quiet now. They wanted to know what she had to say.
"What's the matter, tell me!"
"Sir! Have you ever thought about combining telegraph and telephone? If they are combined together, it will be a huge revolution! It will be a huge opportunity for the group in the future!"
When Xu Hui's words came out, Li Min was indeed shocked.
He has been thinking about this question.
I also want to complete it.
But it just couldn't move forward.
Because there are some restrictions.
When Xu Hui said this, everyone realized that the important thing she said was really important.
Regarding the direction she proposed, everyone actually felt very powerful.
Li Min replied:
"I have thought about this! But there are some restrictions, so I have never been able to implement it. The existing telephone relies too much on lines. If there are no lines, the function of the telephone is useless! Although the telegraph is not limited by distance,
However, its timeliness and the content it can bear at one time are limited, and the efficiency of sending and receiving is very low!"
Li Min pointed out the characteristics of the two.
Everyone was shocked. It turned out that Li Min had thought of it a long time ago, so why didn't he order the research? This is a puzzling question.
Li Min thought to himself that in ancient times, unlike in the future, people could complete calls with a mobile phone.
But the premise is that it is based on a large number of base stations.
In the future, the transmission distance starting from 1G will become smaller.
He also checked the information, and the real coverage is as follows:
The maximum coverage radius of a 1G base station is about 100 kilometers.
The coverage radius of 2G base station is about 5-10km
The coverage radius of 3G base station is about 2-5km
The coverage radius of 4G base station is about 1-3km
The coverage radius of 5G base station is about 100-300m
The higher the speed you want to achieve and the more advanced the communication technology, the more base stations you need. On the contrary, slow speed requires very few base stations.
The frequency band used by telegraph is lower than 1G, and the wavelength is longer.
Therefore, ultra-long distance transmission can be achieved.
In ancient times, only you can use the radio frequency, and there will be no interference. You can do whatever you want.
Li Min also thought about merging the two into one, but he didn't have the technology or talent.
As for combining telegraph and telephone, it's not that he doesn't want to realize it, but that currently, there is no way to realize it.
At this time Xu Hui said:
"Sir's worries are nothing to me, because I have found a new way to combine the two into one! Sir, do you want to hear it?"
As soon as these words came out, Li Min was a little shocked. At the same time, she was overjoyed. She came at the right time!
Xu Hui actually has a way.
You know, she previously proposed a method about plastics, but now she has a new method?
Li Min was overjoyed.
This way, you can do more things.
The timeliness of information is even more obvious.
Sometimes, all it takes is a phone call to get someone to take action.
The five women were extremely happy.
In this way, you can indeed do more things.
At the same time, Li Min was thinking that if there was a telephone in Dayu, Nvtang, he could more easily direct Nvtang's development.
It doesn't have to be in the form of a telegram.
Sometimes the sound is better than the message.
In the future, Li Min's view on text messages is to try not to use them.
What he can say with his voice, he will not say through text messages. He will only send text messages when he has no other choice! When the telephone develops, the telegraph will naturally be retained. The two complement each other and serve themselves together!
"Okay, very good. How feasible is this method?"
Li Min asked.
"More than 90%, now is the critical moment!"
"If you need any help, just ask! I will help you to the end!"
"Sir, when the time comes, I need to build a base station..."
"This is simple, you can build as many as you want!"
"Thank you, sir!"
"Any more?"
"Sir, I don't have any at the moment. I just want to share the good news with you." Xu Hui said.
At this time, Ji Ruxue suddenly asked: "As far as I know, the base station is a good idea, but electricity is a big problem. Just imagine what if there is no electricity? You don't have to pull a wire to the base station, right? If the base station
Haili, what should I do?"
Her worries are not unreasonable.
Su Mei said: "Yes, like Nutang, where we are surrounded by the sea, the wires are not reliable at all!"
When Nü Tang was mentioned, everyone became quiet.
Because they know that there is a queen among the female Tang Dynasties called Jianren.
She can also be regarded as Li Min's beauty.
Xu Hui faces everyone's problems.
She responded: "Regarding this, I have thought of three options, one of which is a small thermal power plant that generates steam power! As long as there are people stationed there, it will provide uninterrupted power supply!
The second option is that I am still working on a solar power generation device, but it will take some time! This one does not require human intervention and can provide continuous power! As long as there is electricity!"
The electricity required for telephone calls is weak electricity.
All it takes is some electricity.
Therefore, Xu Hui added: "If you are in a hurry, you can use batteries in the early stage! But its cost is too high and its durability is not high! But it is still an alternative!"
Li Min said: "Solar energy is a good thing! It is a direction and can be realized. If we want to build a base station, I suggest that each of our five bases should have a base station! As for Nutang, hydropower generation will also be used in the future. If possible, the base station can
It is built next to the reservoir, so this is not a problem, as long as Xu Hui can combine the two, that will be fine!"
"Yes, sir, I will not let you down!"
Li Min touched Xu Hui's head and said.
"I have confidence in you! If you need anything, just ask!"
Xu Hui nodded heavily.
"Sir, I don't want anything, I just want you to remember our promise!"
Li Min:......
Women:......
"Okay, it's getting late. Go back and rest quickly. Later, you can give the plan to my seventh brother and let him supervise the construction of these things!" Li Min felt that he had agreed to do something, so he agreed. He wouldn't
Regretful.
"Yes! Sir, I'm leaving then!"
Only then did Xu Hui leave here with satisfaction.
After she left, Li Min also turned off the lights.
The six of them slept until the next morning. As soon as the sun rose, someone came looking for them.
