Datang Telegraph was not a year or two old, Datang Telegraph Company had been established and operated a long time ago.
Not long after the telegraph was invented, Datang Telegraph Company had already built a complete local wired telegraph system along the railway lines and gradually reduced costs.
Up to now, telegraphs have become an indispensable part of people's life in the Tang Dynasty. They used telegraphs to report safety to their families when traveling far away.
And some people in the upper class have more interpersonal interactions, so after getting up every morning, many people not only read the day's newspapers, but also read telegrams and letters.
But at that time, although the Datang Telegraph Company's telegraph network claimed to have a telegraph office in every county, it was still limited to land.
The laying of submarine cables is more difficult than Datang Telegraph Company imagined.
Not only is the investment huge, but the risk is huge, the most important thing is that the technology is not up to par.
But even if the investment is large, the risk is high, and the technology is difficult, it still has to be done. Datang Telegraph Company funded the Royal Institute of Technology to conduct research, and ran to experiment as soon as some results came out.
The submarine cable between Damuan Island and the mainland has been laid three times!
Halfway through the first installation, the cable broke...
The second installation was successful, but it didn't work for a few days, and then it stopped working for no apparent reason.
It wasn't until the third time it was laid that it was considered a success.
Later, Datang Telegraph Company tried to lay a submarine cable from Shanghai to Edo and succeeded.
The Nanyang submarine cable network was also laid.
It mainly connects four regions: Luzon Province, Banten Province, Malacca State, and Australia.
After achieving success, Datang Telegraph Company started to carefully develop Pacific submarine cables and Indian Ocean submarine cables.
The Pacific Cable was also very unlucky when it was laid for the first time and failed to succeed. It was only the second time that it was successfully laid.
The successful laying of the Pacific submarine cable this year officially means that Jinling can obtain real-time communications with the Americas.
From now on, if there is any disturbance in North America, Jinling will know about it.
It is no longer like before, even if a fast communication ship is used, it will take more than half a month to get the news. If the distance is farther, it may even take a month to get the news.
But even so, Li Xuan was actually not satisfied. Wired telegraphy still had major flaws, especially for wired telegraphs with extremely long distances. If anything happened, the cable would be scrapped.
If you want to achieve truly global communications, you must rely on radio communications systems.
Radio, which has been studied for many years, has recently seen its dawn.
Li Xuan has already seen the report of the electromagnetic project team of the Royal Institute of Technology.
They have successfully sent and received electromagnetic signals in experiments, and now they are building a prototype based on the experiments for real testing.
Li Xuan attached great importance to this, even more than he did to the launch of the navy's latest model of battleship.
The navy's battleships are of little use to the current empire except for showing off, but radios are different.
This is Datang’s weapon to build a global empire!
As long as we have this thing, no matter where it is in the Americas or Europe, Jinling will know immediately if something happens, and there is no need to worry about the communication lines being cut off.
Once something happens, Jinling can immediately dispatch troops via radio. Even if the troops are thousands of miles away in the depths of the ocean, they can be directly contacted and dispatched via radio.
Based on the importance of radio, Li Xuan once again went to the Royal Institute of Technology to inspect, and this time he was still accompanied by a large number of important ministers. Even though he was busy with work, he was only thirty years old this year, but he already looked like he was in his forties. Prince Li Hao, who was almost several years old, was also called over by Li Xuan to inspect together.
The father and son got off the carriage and on the way to the laboratory, Li Xuan glanced at Li Hao and sighed in his heart.
This son works too hard and is busy working every day. The wrinkles on his face are more than those on his own...
He immediately said: "Prince, work is very important, but work and rest must also be balanced. The Queen said before that you haven't visited her for a while, so take some time to rest and visit your mother!" "
When Li Hao heard this, he raised his head, with thick dark circles under his eyes like a smoky makeup, and said: "Father, it's not that I don't want to go. The economic integration plan has just been launched recently, and there are really too many affairs. On point!”
Li Xuan said: "Being busy at work is no excuse for not visiting your mother. You can go directly to see her after the inspection is over!"
Li Xuan said this, and Li Hao opened his mouth several times, but did not refute, but said: "I know it, and I canceled the chemical industry development meeting to see my mother!"
Li Xuan nodded slightly: "This is right. Our Tang Dynasty established our country based on filial piety. As the prince, you must set an example!"
Father and son usually don't talk much, so after saying this briefly, they both closed their mouths.
At this time, several chief professors of the Royal Institute of Technology, the Dukes and Marquises of the Kingdom had already come out to greet them. While his father was still receiving them, Li Hao did some recruiting and called his accompanying secretary over: "Instructions, please The afternoon chemical development meeting has been postponed to tomorrow!”
When the camp secretary heard this, he was a little worried: "I'm afraid we won't be able to arrange the time tomorrow!"
Li Hao frowned slightly after hearing this: "Don't you even have time for a meeting?"
The camp secretary directly took out a small notebook, and then said with a bitter look on his face: "There is really no time to arrange this. Early tomorrow morning, Your Highness will represent the royal family in person at the square in front of the palace to watch the sunrise flag-raising ceremony. He also met with the people and announced the royal family’s academic support plan for poor children in the next year.”
"After the flag-raising ceremony, Your Highness will attend the duty meeting in the Royal Study Room. After the duty meeting, it will be around nine o'clock. Your Highness will meet with several education experts and hold an education symposium to discuss solutions to the difficulties of children from poor families in going to school."
"At nine-thirty, Your Highness will meet with the new ambassador of the King of Spain and accept the credentials, and discuss European issues. At ten o'clock, you will meet with the governor of Haidong Province, listen to his report on his work, and discuss the empire's strategy for Central Asia and West Asia.
"At eleven o'clock, we will go to the Naval Headquarters Auditorium to hold a promotion and medal ceremony for this year's meritorious officers of the Navy."
"There are more arrangements tomorrow afternoon, and I can't spare any time... Originally, I could still be free during lunch time, but due to changes in my schedule this morning, a symposium and a textile industry conference originally scheduled for this morning have been moved. Tomorrow at noon."
Li Hao looked a little unhappy: "What about tomorrow night? Move the meeting to dinner time."
When the camp secretary heard this, he hesitated, but still said: "Your Highness, tomorrow night is the time for you and the Crown Princess to go to the theater together. The Crown Princess has already made an appointment half a month in advance..."
"Moreover, this is already the third time the Crown Princess has made an appointment. Ms. Zhou on the Crown Princess's side has already given me an ultimatum, saying that if I dare to change my itinerary and cancel the appointment again, she will make me walk around without food. …”
After saying that, he gritted his teeth and said with a sad face: "Your Highness, there is nothing I can do!"
Li Hao closed his eyes slightly after listening to these words from his camp secretary!
