On the weekend, I talked with the children at home about the communication tools of the past, and the children came to be interested, so I asked them to introduce them to how the mobile phone evolved step by step to what it is today.
I found some representative mobile phones that I had used at home and arranged them in a row. As soon as this person is old, it is easy to be nostalgic, and friends who have used the previous paragraphs should also be middle-aged.
To understand the evolutionary history of mobile phones, we have to mention the grandfather call machine of mobile phones, also called bp machines, pagers, and scientific names are pagers, as shown in the following figure, Wu Yanzu's movie "Riot Elimination" has this style of pager.
This pager was bought by my father in the nineties, it is said that I originally planned to buy furniture, and then I bought a pager on impulse, don't look at this thing neither can call, nor text, at that time can be compared to buying a new mobile phone with a folding screen at that time, it is more windy than buying a new mobile phone with a folding screen now, don't put it on the trouser belt like a browning, enough to make people who see it awe-inspiring, because maybe only one or two people in ten miles and eight villages have a pager.
The role of the pager is just like its name, if someone is in a hurry to find you, you must first find a landline to dial the call machine number, the number I remember 126-2947955, but now there is no such service. Then you'll get a string of numbers, yes, a landline number, and knowing that someone is looking for you, you'll have to find a landline phone to call the other person back, so that you can pass on a simple paging function.
Later, I slowly had a Chinese pager, that is, I could send a little text, similar to shooting a telegram, but it was precious, and I could not express my literary style, and I must spare words like gold. Those big brothers from Hong Kong did not appear in the inland city where I live, and I am not familiar with it, but it seems that there is a program computer with an antenna like PHS, and when it is used, you need to pull out the arm-length antenna first, because I have not found the actual object and there is no way to introduce it.
After 2000, mobile phones gradually became popular, and the mobile phone I first used in my family was Siemens, with an antenna, which was broken open from behind to insert the calling card and battery, black and white screen, with punctuation marks to send up to 70 characters.
At that time Nokia and Motorola were the absolute industry bosses, Nokia mainly resistant to falling, known to be able to smash walnuts, Motorola V series of the main high-end, at every turn tens of thousands of yuan, at that time this price can buy more than ten square meters of houses in Shenzhen. There is also Japan's Sony Ericsson, the main music mobile phone, South Korea's Samsung, buy mobile phones everything to send, mobile phone manufacturers also began to produce flap, slide, rotary cover and other different types of mobile phones, my family at that time bought a Samsung clamshell machine, but also sent a badminton racket and a bunch of wristbands.
The domestic brand has a waveguide, known as a fighter in the mobile phone, I also bought one, did not feel like a fighter, but also often crashed. Gradually appeared can take pictures of mobile phones, and the pixels are getting higher and higher, around 2010 cottage machine rampant, Huaqiang North one square meter of stalls fried to 3 million, mobile phones began to integrate more and more other electronic products function, indirectly killed many digital cameras and other electronic products. The music playback function of mobile phones indirectly replaced mp3 and mp4, and with mobile games, it indirectly replaced portable game consoles and became indispensable personal items.
But the real mobile phone revolution began with Apple to change the mobile phone to a full screen, gradually replacing the design of the flip cover, slider cover, and rotating cover, and all mobile phone manufacturers adopted the touch design to become what they see now, but the screen size is constantly getting larger.
My two children listened to God because when they were born, the phone was already the way it is now, so they thought it should be the way it was since ancient times. Finally, I said, you are constantly making progress when you look at your mobile phones, do you two also have to continue to learn, keep making progress, and learn the skills to contribute to the construction of the motherland in the future.
