My 1982
Chapter 465 Wiisjgkcg
() The main business made by Iisjgkcg is a base station construction and base station equipment. What is the two business do?
This is not necessary to build this base station, it is to build a base station.
The Equipment Of Base Station refers to the device that controls the reception and transmitting radio signals, which constitutes a two-way telephone circuit between the mobile station.
That is, the public mobile communication base station is a form of a radio station, refers to a radio receiving station that transmits information between information between the mobile phone terminal in a certain radio coverage area.
At this time, Japan attaches importance to the technical application that can be converted into product production, and the application type information industry is relatively developed.
IISJGKCG is also relatively developed in terms of base station construction and base station equipment. The main operational objects of this base station equipment are BP.
Many young people in the later generation of BP machines may already have something, but this BP machine does not want it in the 1980s.
The BP machine is called a user receiver in a wireless paging system.
Composed of a superheterodyne receiver, a decoder, a control, and a display.
It selects the useful signal required to receive from the paging signal and interference transmitted by the base station, restores the baseband signal of the original page, and generates a sound (or vibration) and the display number (or letters, Chinese characters) messages.
Li Zhongxin remembers very clear that the Municipal User used in the eighth year is just analog signal BP machine. Users can only accept call signals, and they need to call the temple to query the return number.
From the eighth year of Shanghai, the business of the BP machine began to have a BP machine until eight or four years, and there are no such developed regions to have such a whole year.
At this time, there is no such thing in the Northeast, and the construction of the base station has only the super big city on Shanghai and Guangzhou.
The equipment used in the construction of the base station is basically purchased from Japan's large-scale communications companies.
Li Zhongxin saw the business opportunity that other people could not see.
Base station construction and base station equipment These two things have been great, others do not say, producing products can reach the effects of the result.
Iisjgkcg's construction base station and sales base station equipment in Japan, this is too normal, and Japan's development in communication is more than a few decades higher than China, and Japan does not need such equipment, just exported China's side.
There is nothing to grasp it, but the black province, which is the base station, introduce the base station equipment, so that the black province will make an early step into the mobile communication era or not too much problem.
Li Zhongxin also felt the shortcomings of the mobile phone at this time, at this time, as long as it came from home or from the unit, then others want to find you, just wait for you to reach another position before you can find it. You, if you introduce this kind of business at this time, you will carry out such a business, then, when you want to find anything, that speed will be much faster.
The other side of Shanghai and Guangzhou is the country focusing on the country. They take the lead in having BP chapse business, and the black province has such a business as soon as possible, at least in the province, I want to find a person. Convenient.
Base station construction and base station equipment installation are not a thing, this construction and installation require at least one year and a half years.
It is now in September 19, that is, if you start studying this at this time, IISJGKCG introduces IISJGKCG, then the base station of the black province will soon be able to build.
This is a win-win situation. He now acquires Iisjgkcg, carrying the company's main business to the side of the community, nothing more than the price reduction.
Reducing some prices, although less than a little, but with Iisjgkcg's success in the black province's construction base station, China's other provinces will know that there is a company specializing in this base station in Japan. At that time, Iisjgkcg It will have a long and fast development.
Li Zhongxin remembers very clear that the early BP machine is all imported products, including Motorola, Panasonic, etc.
The BP machine can only receive the radio signal, and the signal cannot be transmitted, so it is a unilateral mobile communication tool.
If a girl dials the number of the tower through the waters, after the phone is connected, she tells the owner to pace the BP machine number and her name and phone number, then hang up. The attendant of the page will automatically send call information to the air immediately below the computer, the transmitter automatically issues call information to the air under the control of the computer.
You may ask, since the radio wave transmitted by the hoping station can cover a certain area, then the BP machine in this area can only receive the call to his own call, and the signal does not receive someone else?
It turns out that all BP machines have their own numbers, stored on the computer of the page. The information sent by the page is with this number, which can only start the corresponding BP machine, and there is no effect on other BP machines. This is like a postman, sending information according to the user's house number, will not be wrong.
After the girl's friend heard the "B-, B-" sound, opened the display switch, and the number requested to return to the screen, so her friend can find a phone nearby, come and call the girl.
China's public page number is 126 and 127, and there are also some professional page, the number is 7-digit or 6 digits. 126 and 127 are all utilities, but the use method is different.
126 units are connected by the operator, it is artificial search, and 127 is controlled by computer, called automatic search.
The above girl is used by artificial search. If you want to pass 127 games, after the phone is turned on, he heard is just a good priority, such as "Continue Dial". Then you have to put the pagraced number through the button of the phone in your hand.
After the computer of the page is accepted, after the check is checked, paging in the wireless channel.
Some paging devices are also associated with a telephone in the home. After the phone is ringing, after a certain time
If no one picks up, the call will automatically go to the hoping station.
The pager is small, lightweight, and is cheap, easy to use, which makes it widely used in various industries.
From the instant communication started from the BP machine, people brought people without time and space, and they can be found at all, which greatly accelerates people's lives, work efficiency.
Later, in the wave of domestic enterprises and Motorola, developed Chinese character BP machines, allowing users to know call content without the streets.
In 1987, when Motorola's mobile phone had just entered the mainland, there was a strange name called "Big Brother". This is actually a homophone of the Guangdong, Guangdong, Hong Kong. It is said that the mobile phone is related to this name and the movie star Hong Jinbao.
At that time, when he was directed in the film, his mobile phone never leaving, and often used the mobile phone number. Hong Jinbao is originally a champion of Hong Kong Movie Master, others respect him for Big Brother.
Because of the photos of his mobile phone, everyone also sighed with "Big Brother" to refer to mobile computers. Regardless of whether this source is true, the information carried by "Big Brother" is clear. In that year, it is a symbol of identity, status and wealth.
For recently, it is considered "upstairs downstairs, the electric light phone" is a Chinese who moves "Xiaokang", and the shock it brings is inevitable. This is not only because of its expensive, but also because of its magical magic.
The emergence of Big Brother means that China has entered the era of mobile communication.
Later, in order to achieve mobile communication with Hong Kong and Macao, Guangdong took the lead in building a 900MHz to simulate mobile phone.
Motorola also established offices in Beijing and promoted mobile phones. This heavyweight mobile phone, thick and cumbersome, like a black brick, and the weight is in one pound.
It does not have other functions in addition to calling, and the quality of the call is not clear and stable, often shouting. In addition, after a large battery is charged, it can only maintain a 30-minute call.
Even so, the big brother is still very tight, and it is difficult to find it. At that year, the big brother public price is about 20,000 yuan, but it is generally to spend 25,000 yuan to buy, the price of the black market has reached 50,000 yuan. This not only makes the general people, it is not much smaller than that of SMEs.
The people in that age are very simple, never hide their admiries to others. Many people quickly opened their own social circles because of the big brother.
For a time, comb your back, wipe the glue, holding big brother, became a lot of people's ideals.
The people in this era must not expect that there will be a small and exquisite mobile phone in the hands of the streets.
Although the rough big brother and its long-day lines have been fixed in the historical long volume, those featuring scenes are still worthy of repeated taste. Because of the big brother who is born in the air, the life of the Chinese people has attracted Chinese people to a new realm.
Li Zhongxin thought excitedly, since Iisjgkcg, since it is doing this business, then he must take a matter of such a thing, the decision made by the three wells, it is too happy.
