"Continue testing, now the distance is about four miles, and there is still a sound" In the department, there was a hint of a female voice with a murmur, which was the four women in spring, summer, autumn and winter talking through the walkie-talkie The success of the walkie-talkie greatly boosted the confidence of everyone in the department, but at the same time, they also wanted to know where the limit of the walkie-talkie was Even if everyone already knows that the walkie-talkie is just a test product for the front station, it is still necessary to figure out its limits When the distance between the two places was raised to more than four miles, a murmur had already begun to come from the intercom However, in the end, he persisted until his early seven miles, and some staccato sounds could still be heard, but that's all. \ In the end, he continued, but he never exceeded seven miles, and when he was close to seven miles, there was no signal at all, and he could no longer hear the other party's voice "About seven miles, converted into kilometers, more than three kilometers is enough" Lin Zifan couldn't help but smile slightly.
Even if it is a modern walkie-talkie, if there is no other auxiliary equipment, the communication range is only about three kilometers.
This test, spring, summer, autumn and winter are all in Chang'an City, many buildings are lined up, the terrain is complex, in this case it can reach more than three kilometers, the walkie-talkie is undoubtedly successful "Then it's time for the next stage of development and testing."
After returning from spring, summer, autumn and winter, Lin Zifan directly announced that he would begin to develop a radio station for long-distance communication The time of the task is only one month, which is not too long, not to mention, after more than a month, Lin Zifan will marry the empress, and he will inevitably be busy for a while.
In other words, Lin Zifan must get all this done within a month, so as not to make the rest of the time seem too busy.
"However, this pair of walkie-talkies is not completely useless" Looking at the walkie-talkie in his hand, Lin Zifan's mind turned and he thought of the use.
Now, the empress's bedroom has really moved to a high-altitude villa The empress can fly now, but there is no problem, she can fly directly and fluttering, but Lin Zifan cannot If the empress is not there, if Lin Zifan wants to go up, he can only climb Even if he later used the ability of the wood system to make the branches entangle together to form a wooden ladder, which went straight to the sky like a ladder, it still hurt a little to climb thousands of meters.
It's a bit of a waste of time.
It's not just Lin Zifan, such as Tsing Yi and Ziyi, or civil and military officials, if you want to find the empress now, it will be a little troublesome The civil and military officials are slightly better, and they are not good at climbing the tree directly, if they have something to find the empress, they will call under the tree, to put it bluntly, it is to call under the subordinates Tsing Yi and purple clothes are different, they also have to shoulder the task of delivering meals to the empress, climbing up and down every day, it is a little troublesome, and it is not very convenient to notify the empress to come down.
You can't just shout down there every time you get to the meal, which is too damaging to your image If there is this pair of walkie-talkies, one for the empress and one for Tsing Yi and purple, wouldn't it be enough?
Of course, the best thing to do is to have one on the tree and the next on the tree In this way, no matter who goes under the tree, if the empress is in the tree, she can communicate directly through the walkie-talkie, without so much trouble, and there is no need to shout to affect the image In the evening, when Lin Zifan put the walkie-talkie and turned it on, the call of Tsing Yi and purple clothes suddenly came from the walkie-talkie, which looked like a brick, and the empress was instantly stunned.
"This is" "Walkie-talkie, it can talk to people under the tree normally, Your Majesty try" Lin Zifan said with a smile.
The empress nodded slowly, very curious and puzzled, but still said softly: "Tsing Yi Ziyi, can you hear my voice?"
"Your Majesty" On the walkie-talkie, the two women cheered in surprise and excitement: "I can really hear His Majesty's voice, our sisters thought that Lin Shangshu was blowing their foreheads" "However, this pair of walkie-talkies is really so magical" "There's such a thing" The empress was completely surprised Clearly separated by thousands of meters, but they can have a normal conversation as if they were face-to-face, this method is really too unbelievable in the eyes of people in this era.
Even if she is as strong as the empress, she was surprised when she saw the walkie-talkie for the first time.
"How did you come up with it?"
"I had an idea, I thought we needed something like this, and I came up with it."
Lin Zifan coughed dryly and lied.
This kind of thing must not be told the truth, otherwise, there will be too many problems in the future, and it will be difficult to explain in one word "Is that so?"
The empress looked at Lin Zifan's gaze, a little strange, but in the end she didn't say anything, but asked an extremely important question: "This walkie-talkie, how far away, can talk normally" The empress asked directly to the point.
Obviously, it is impossible for two such small things to talk normally in the north and south, which is simply impossible However, the empress never thought that the communication distance of the walkie-talkie was infinite As long as it can cover all parts of Datang, the role and value that walkie-talkies can produce are immeasurable "At the moment, there are less than seven miles of land."
Lin Zifan smiled: "However, within a month, it should be possible to increase the communication range to the point where you can talk normally from Chang'an to Asan Province."
"It can cover Datang and Asan" The empress said: "It can really be done" Although she had thought so before, the empress was ready to be disappointed, but she didn't expect that Lin Zifan would give a more perfect answer than she imagined It can not only cover the entire Datang, but also cover the three provinces If that's the case, it's too big The empress instantly saw the importance of the walkie-talkie With the existence of this thing, Datang is too much more convenient From now on, whether it is military scheduling, business development, or policy announcements, you can completely cancel the previous time-consuming and laborious means such as messengers and cloud eagles, and turn to the direct use of walkie-talkies The speed of this thing's conversation is like two people talking face-to-face, much faster than using messengers and sending books to Yunying or something When that day comes, Datang's military command and combat effectiveness will improve in a straight line Regardless of the others, this alone is enough to illustrate the importance and value of walkie-talkies At this moment, in the eyes of the empress, the value of the walkie-talkie is not a priceless treasure, or in other words, the value is immeasurable xb1806091:
