Li Shimin came to the balcony." Young Master Wang, the phone said there was no signal?”
Wang Zhao beckoned." Come down first."”
Li Shi Min ran down to the passageway.
Wang Zhao explained," It's normal that there's no signal because the signal can't be transmitted there. At most, the signal can be received near the passageway.”
"But what is this signal?”Wei Zheng asked.
"First of all, to make a call and establish a connection, which is to establish a conversation channel, we need the help of something else. This thing is called a base station.
The base station had a service range. When your phone was outside the service range, the phone would alert you that there was no signal.
Therefore, this signal could be understood as the service range of the base station.”
Wei Zheng thought about it carefully.
"I understand. It seems that making a phone call is quite complicated.
Then how is Young Master Wang going to solve the problem of us not having a signal? Do we need to build a base station?"
"That's right."
Soon after.
Wang Zhao went online and ordered a portable base station.
The base station was not big and looked like a household cleaning robot.
Wang Zhao had installed a base station in his house, directly opposite the entrance to the passageway.
The service range of this base station was 500 meters, so the Dew Palace would be covered by the signal.
"Old Li, go make another call.”
Li Shimin ran upstairs again. Not long after, Empress Zhangsun received a call from Li Shimin.
She swiped the green arrow on the screen and the call was connected.
"Hello, Guanyin maid, can you hear me?”
"I can hear you, I can hear you."
"Then I'll hang up first."
After a while, Li Shimin ran down from upstairs.
He said excitedly," With the base station, you can make calls in the Tang Empire.”
“
However, the range of the call was not too wide. It was limited to the palace and its surroundings.
This was because it was impossible to install such portable base stations throughout the Great Tang.
”
Li Shi Min nodded.
"However, I hope that the signal can spread throughout the Great Tang. That way, the soldiers on the border can use a phone to call their families thousands of miles away.”
"If we want the signal to cover the entire Great Tang, we need to build a large base station. Sometimes, we also need the help of communication satellites, which can be understood as an even larger base station.
If we have a large base station or a communication satellite, we won't be able to rely entirely on our side to make calls in the future, because the world here will discover that something is wrong. At that time, the Great Tang will have to establish its own telephone service.
It was clear that the Great Tang was currently incapable of doing so.”
Li Shi Min's eyes were filled with hope.
"Thus, our Great Tang should learn the advanced knowledge of the future world and hope that we can communicate with the entire Great Tang as soon as possible. Of course, there were also various powerful things such as building power stations.”
Li Shi Min cupped his fists and said," I'll have to leave this matter to Young Master Wang."”
"You're welcome. This matter can be discussed easily."
Wei Zheng walked forward." Young Master Wang, if I were to sit at home now, would I be able to call King Tang?”
"That depends on how far your house is from here. The service range of this base station is 500 meters, which is one mile.”
"My house is three miles away from here. It seems that I can't make a call.”
At this moment, Li Shi Min heaved a sigh of relief.
Wei Zheng changed the topic." However, you can install a few base stations between my house and the Dew Hall. I'll pay for it.”
Li Shi Min felt despair again.
Wang Zhao noticed his expression and held back his laughter as he said to Wei Zheng," This matter is easy to resolve. I bought a bunch of base stations.”
