Chapter 221 Test Machine

"Minister Tan, happy New Year, you see, our project has also alarmed you, and I took time out of my busy schedule to come and personally care for us, so that we can be business people, my heart is warm."

In the Second Institute of the Ministry of Posts and Telecommunications in Yanjing, Li Jian greeted Tan Yongsheng, who came to visit, and shook his head angrily at Tan Yongsheng with an exaggerated look.

"You little ghost, what am I busy with during the New Year, it's not for your project, this thing is not something that one of our ministries can decide, your shelf is big enough, let me, the minister, go to various places to lobby you, you can talk about it, how to calculate this remuneration?"

As soon as Tan Yongsheng spoke, the serious expression that had just been put up was completely ruined by the smile on the corner of his mouth, and in the end, he simply smiled and said, Li Jian hurriedly waved his hand,

"I don't dare to talk to a servant of the people like you about remuneration, this is a sugar-coated cannonball, don't give me a charge of eroding state workers, I can even finish the game, and, this cooperation, the benefits of the Ministry of Posts and Telecommunications are much greater than the interests of our Qianghua, we just sell equipment, which is a disposable consumable, but you are selling services, which is a monopoly type of consumption, as long as they want to use it, they have to keep paying, if they are paid, the Ministry of Posts and Telecommunications should pay us."

"You just give me nonsense, I should give you a few hard blows like Tang Yang's father beat him, so that you can be obedient, hurry up and take out the things, let me see the effect."

Tan Yongsheng looked at Li Jian, and he felt like he was looking at his grandson, who was a few years younger than Li Jian. is still in school, but he is not as naughty as Li Jian, in front of his grandfather, who has always been majestic. It's even more restrained like a kitten.

"Order, I'll go get it."

Li Jian trotted to the laboratory of the second institute, he and an engineer named Wang Zhouguang were observing the data of PHS just now, and someone notified Minister Tan Yongsheng to come to inspect, even if he put down his things and ran down, he didn't need Wang Zhouguang to go back to get it at this time, he already knew the way.

The second building is a four-story concave building. There is a small courtyard surrounded by a building on three sides, which looks like a quadrangle, but outside this quadrangle. There is also a fence and a large iron gate.

Li Jian climbed up to the second floor, took down PHS, and handed it to Tan Yongsheng, who looked at the microphone about the size of a teacup. Squinting. Rubbed it with your hand for the exterior with a matte back.

"Isn't this the microphone of your cordless phone?"

"That's a big gap."

Li Jian didn't need Wang Zhouguang to introduce him to Tan Yongsheng, and began to point to the mobile landline he named PHS to explain to Tan Yongsheng.

"This PHS, in terms of volume, is larger than the microphone of a cordless phone, and it is correspondingly heavier, which is not a technical regression, but the reason for the battery. The microphone of a cordless phone is usually near the phone, and it doesn't take too long to leave. Even if you find that the microphone is out of power, you can put it back to charge at any time, but PHS is going to run around for a long time with the individual, and the power must be able to ensure about 20 hours of application, so the battery capacity must be larger than that of a cordless phone. ”

Li Jian opened the back cover, revealing that there was a battery the size of half a box of cigarettes, which was connected to the body through red and blue wires, and the roughness was not much different from the battery connection method of remote control cars in later generations.

But such a thing, in this era, doesn't seem to be a problem.

"This is the antenna, here is the screen, this is the volume adjustment ......"

In addition to being larger, this PHS is similar to the big brother phone that once swept Hong Kong and Taiwan, and other places are basically the same as the PHS of later generations.

Press the button,The green two-inch screen lights up,Under the backlight,The top of the screen is displayed with two words of swiftness composed of black pixels,These two words,It has been set by Li Jian to be changed,And the number of words can also be changed,This is definitely a highlight for some users who like to sell cute。

Imagine a little couple who just joined the work, when they took it out to make a call, they saw that the other party's PHS actually had their own name on it, and the words I love you were embellished behind it, which was definitely moved to the rhythm of crying instantly.

It's just that for Tan Yongsheng, this thing is just a little bit of novelty.

"Well, let me try, how much area can your base station cover?"

Tan Yongsheng raised his head and looked at the iron tower on the top of the four-story building, because of the reason at the top of the building, the iron tower itself is not very high, but standing on the ground, he needs to look up to nearly ninety degrees to see the spire.

The iron blue tower body is brushed with a special protective coating, which looks a little cold.

"The height of our base station is 60 meters, because it is a test, the user is single, that is, the minimum usage and the maximum coverage area, theoretically there should be a coverage area with a radius of 30 kilometers, but if in order to ensure the quality of the call, 25 kilometers should be no problem."

Li Jian gently calculated, according to the expected usage, the city center of a medium-sized city should be the most densely used place in PHS, at this time the base station must not be in accordance with the maximum mode, on the contrary, it should be calculated according to the coverage of the minimum mode and the maximum user usage, if only about five years of development is considered, the city center of three million people, mobile fixed lines should not exceed 10,000, so the coverage only needs to cover about ten kilometers.

"Oh, it's so far, how many test machines do you have now?"

Li Jian stretched out three fingers, because of the tight time, he only rushed out three prototypes for the time being, and all of them were brought to the Second Institute of the Ministry of Posts and Telecommunications.

"Xiao Cui, you mark the number, take it, after you get to the eastern suburbs, call this number, Zhao Yunchuan, come here, take one too, go to the west about twenty-five kilometers, call this number, remember the number, and I will call you when the time comes."

Tan Yongsheng casually beckoned a director who came with him to inspect the second institute, if you look at the level of this experiment, I am afraid it is the highest standard experiment in China.

"Minister Tan, don't be so troublesome, in this way, you can dial the phone that Director Cui took, talk to him all the time, talk with him until the destination, and listen to whether the quality of the call is affected, not more thorough."

Li Jian took the last phone he left, dialed a few numbers directly, and heard the ticking ringtone of a home phone at the door of the second office.

"Li Jian, why do I listen to your pager when there is a message, the voice is much better than this, is this kind of mobile phone not as good as your pager?"

Tan Yongsheng took the phone handed over by Li Jian, and asked strangely, Li Jian stuck out his tongue,

"I'm an experimental product, so I added a lot of novelties, and the ones sold on the market are definitely not so advanced, I'm a black-hearted businessman, and I will charge more money if I add a little function, so this ringtone, until the next generation of products is launched, will be sold at a higher price, so that every time a new product is launched, something new will be added, and users will have more expectations."

"Hell, my mind is full of ideas to make money, and I will give us ideas for the Ministry of Posts and Telecommunications when I go back."

Tan Yongsheng listened to Cui Zhengping's voice from the microphone, ignored Li Jian, and began to talk to Cui Zhengping.

"Give you an idea to the Ministry of Posts and Telecommunications and let you make money, isn't that scolded by the people, if you make money, we ordinary people will have to spend more money."

didn't want Tan Yongsheng to hear this, Tan Yongsheng glared,

"Let you give ideas for the Ministry of Posts and Telecommunications, not to loot the people's money, but to better serve the people, your brain has been influenced by the bourgeoisie too much, and you should be sent to the Central Party School to listen to lectures."

Li Jian hurriedly shut up, the Ministry of Posts and Telecommunications at this time has not been split, it is not a company for profit, but a pure party and government organ, even if it collects money to make profits, it is in accordance with the regulations, and it is handed over to the state treasury after deducting a certain percentage of expenses, which is not the later monopoly enterprise he complained about at all, so Tan Yongsheng reprimanded him, and he could only listen and couldn't refute it.

didn't dare to stay by Tan Yongsheng's side, so Li Jian took this opportunity to hide aside and wanted to talk to the experts in mobile communications of the second institute, but these experts were completely absent-minded because the minister was on the scene, for fear that they would not behave well, and they were all a little uneasy.

Li Jian had to sit on the side, considering the load of the base station once it is commercially operated, if it is a mature communication market, before the establishment of each base station, it is necessary to consider the coverage area of this target area, what is the population density, what is the target customer who uses the base station, what is the peak and valley value, how often is the use, how many roads are in the area, and the customer development expectations in the region in the future for a period of time. Then select the most robust coverage to determine the coverage of the base station.

But at present, everything is starting from scratch, Li Jian does not even have a ready-made model, and he cannot estimate where the target area is, so he must wait for the Ministry of Posts and Telecommunications to pass the verification, and the post and telecommunications bureaus in various places will count these data and propose the development plans of their respective cities.

"You kid, what are you doing hiding here, this call is good, Xiao Cui has already driven to the East Twenty Miles, and it is still the same as what he said just now, let me ask you, this time you kid won't target abroad again, right? The Ministry of Posts and Telecommunications has worked hard to cooperate with you, and if you still have your elbows turned outward, be careful that I will whip you with a belt. ”

Tan Yongsheng turned around, and then found Li Jian in the corner, Li Jian hurriedly waved his hand,

"No, don't wronged me, I can't bear to make money from my own country, I don't always put foreigners' dollars in our own pockets, but this time, there is an opportunity to make money, I don't need to, let's give priority to the development of domestic post and telecommunications industry, how about it, Minister Tan, my consciousness has become higher in a while."

As long as this old man nods, the country will immediately reduce the backwardness gap of ten years in the communications industry, but surpass foreign countries for a few years, Li Jian thinks about how excited he is to realize this matter in his own hands. (To be continued......)
