What is the history and popularity of mobile phones in China?

The era of simulated mobile phones in China can be roughly counted from the beginning of China Mobile Communications Group Company's operation of 1987 simulating mobile telephone service at 900MHz to the end of June 30, 2006 when China Mobile Communications Group Company completely stopped the international and domestic roaming business of simulated mobile phone network customers. Analog mobile phone system mainly adopts analog and frequency division multiple access (FDMA) technology, which belongs to the first generation of mobile communication technology. Any mobile phone with a number beginning with "9" belongs to an analog network. The analog cellular phone signal transmitted by radio waves simulates the fluctuation of human voice, so this communication mode is called "analog mode". The quality of analog mobile phone system can be comparable to that of fixed telephone, so that both parties can clearly hear each other's voice. However, compared with digital mobile communication, analog mobile communication has poor confidentiality and is easy to be stolen by parallel computers. Only voice services can be realized, and colorful value-added services cannot be provided; Small network coverage and poor roaming function; Analog mobile phones are bulky, heavy and outdated. Mobile phone suppliers have long stopped producing analog mobile phones, which seriously restricts the maintenance and update of analog mobile phones. China Mobile Communications Group will close the analog mobile phone network and stop operating the analog mobile telephone service after 200 1 12 3 1. In 1980s, the global mobile telephone service developed very rapidly. In the late 1980s, the annual growth rate of users using wireless telephone terminals worldwide was 40%, far exceeding the annual growth rate of wired telephone users in the same period. In the first few years of 1990s, the annual growth rate of wireless paging users was 30%-40%, that of cordless telephone users was about 30%, and that of mobile telephone users was as high as 40%-50%. Mobile phones have changed from analog to digital, and digital mobile phones, including GSM and CDMA systems, are developing rapidly all over the world.

Motorola is the first company to enter the mobile phone market in China. Once monopolized the mobile phone market in China with absolute superiority. Most mobile phones in the era of analog mobile phones are Motorola products. I remember watching movies from Hong Kong and Taiwan. There are many big bosses above them, and everyone around them has a mobile phone, which can even be used as a weapon when necessary. The Motorola 3200 next to it probably belongs to this category. Looking at its huge fuselage and long antenna, I simply feel that this is not a mobile phone, it is simply a killing weapon.

The first flip phone: Motorola 8900

Motorola 8900 is commonly known as "big brick". In the late 1980s, mobile communication began to enter the China market. In China, it is called "Mobile Phone" and can also be used for self-defense. The highest price reached 30,000-40,000 yuan. Although ugly, don't underestimate it. It is the first flip phone. Because it has a flip cover, it won't turn on and send a signal because you accidentally touch a button in your pocket. It's very safe! Later, Motorola introduced 9900, the successor of 8900, in the early 1990s. Because of its small size, light weight and durability, it used to be the exclusive pet of white-collar women. But it is the same as the 8900 model, using a nickel-chromium battery, and the power is too small. 1995 has always led the fashion of mobile phones, and the highest price has reached about 20,000 yuan.

In the era of analog mobile phone, the function of mobile phone is often limited to the call function, which is limited by technology, materials and other aspects. The style is quite single and lacks change, which is called the prehistoric era of mobile phones. China's GSM digital network can probably start from 1994 when the first GSM communication network was built in China, and the analog network will be switched to the network in 200 1 year. GSM digital network has completely replaced the coexistence of analog and GSM networks, and has developed to this day. At present, GSM technology, which is widely used in China, adopts narrow-band TDMA, allowing eight groups of calls to be made at the same time on one radio frequency (that is, "cellular"). GSM digital network also has the advantages of strong confidentiality and anti-interference, clear sound quality, stable call, large capacity, high frequency resource utilization, open interface and powerful functions. No one can compete with Motorola in the era of analog mobile phones. 8900 and 9900 mobile phones are called "mobile phones" and once became synonymous with mobile phones in China. In the post-GSM era, all mobile phone manufacturers are optimistic about this new opportunity and scrambling to expand their share in this market. Motorola refused to give up its existing site and locked in the analog network, which made it unable to adjust its market strategy in time and its dominant position declined rapidly. At the same time, Nokia, Ericsson and other manufacturers came from behind and called them the three overlords.

The first GSM mobile phone to enter Chinese mainland: Ericsson GH337

In the era of analog network, GH337 is the first GSM mobile phone to land in Chinese mainland. At that time, the GSM network in Guangdong Province had just been opened. As a digital mobile phone, GH337 is much better than an analog mobile phone in all aspects, so everyone can buy it. GH337 weighs 220g, and its circumference is 130×49×24 mm, which is suitable for 900MHz GSM network. Compared with analog mobile phones of the same generation, it has the characteristics of fast line grabbing and sensitive signal receiving.

The first mobile phone supporting ringtones: Ericsson GH398

I don't know why this pure black mobile phone always reminds me of Panda 5 18. Its square figure is really not cute. GH398 introduced by Ericsson 1995, net weight 170g, measurements 130× 49× 23mm, equipped with 650mA Ni-MH battery. It is not because it is handsome, but because it is the first mobile phone that can make its own ringtones. But at that time, GSM mobile phone was still a high-end consumer product, and many mobile phone users used music ringtones to avoid being mistaken for toy mobile phones. But it is precisely because of the guidance of Ericsson that the ringtone of 1999 will shine brilliantly.

The first mobile phone without antenna: Hanojia CH977 1

This CH977 1 with mechanical control and ergonomic S-shape design introduced by Hanojia is the first mobile phone with built-in antenna, although the cold lines make people feel lack of affinity. CH977 1 weight168g, available in grey, black and red. Although the response of this mobile phone in China market is not great, the design of the built-in antenna has been adopted by Nokia, Siemens and other companies, and it has achieved great success in the mobile phone market.

The first mobile phone with built-in games: Nokia chameleon 6 1 10.

Nokia, which has been focusing on the youth market, is the pioneer of mobile games. Later, it was imitated by other brands of mobile phones, and there are more and more types of games. However, Nokia's first mobile phone with built-in games is 6 1 10, which contains three games: snake, memory and logical guessing. Among them, the "snake" has spread to this day and has become a traditional project of Nokia mobile phones. 6 1 10 weight 142g, measurements 129× 47× 28mm. There are three colors available: blue, gray and purple.

The first folding mobile phone: Motorola palm treasure 328C

Motorola Palm 328C can be regarded as a classic in the past, and this invention of Motorola made the folding mobile phone develop from now on. The weight of 328C is only 95g, which can be called lightweight in that year. Especially the flip design surprised Ericsson fans at that time.

The first dual-screen mobile phone: Samsung SGH-A288

Folding mobile phones are very popular, but it is not convenient to see whose phone or clock it is every time you open the phone. In order to solve this problem, many manufacturers have launched their own dual-display folding mobile phones. Walking in the front is Samsung SGH-A288. SGH-A288 follows the ultra-small and ultra-light design of folding mobile phone, with a volume of only 79X38X23 and a weight of only 77g. As for colors, there are three choices: champagne gold, pearl white and silver gray.

The first dual-band mobile phone: Nokia 6 150

Dual-band system is actually the application of GSM technology in different frequency bands (900Hz and 1800MHz), that is, the GSM 1800 (also called DCS 1800) system with the same standard is superimposed on the original GSM900MHz system to form a dual-band system, which can theoretically double the number of users. In appearance, 6 150 is similar to 6 1 10, but its dual-frequency characteristics were unique at that time. 6 150 weight 142g, perimeter 129× 47× 28mm. Suitable for GSM900MHz/DCS 1800MHz network, available in blue and red.

The first tri-band mobile phone: Motorola L2000

Motorola L2000 not only supports GSM900/ 1800MHz, but also supports the working frequency of PCS 1800MHz in North America, so that users can truly enjoy the global roaming service of GSM. However, there are very few consumers who can really enjoy the tri-band service, and the role of tri-band can only be said to be "preparing for a rainy day". But it is undeniable that the tri-band function can really facilitate business people who often go to the United States for business trips. L2000 weight 108g, measurements 130× 46× 24.5mm, suitable for GSM 900 MHz/DCS1800 MHz/PCs1900 MHz networks, and available in three colors: Athens black, Galaxy gray and dark blue. In addition, the L2000 also has a built-in modem, which can transmit data, send faxes, e-mails and browse the Internet when connecting to a computer with an external data cable.

China's first mobile phone: Motorola CD928+

When it comes to appearance, I only think of soap. If you don't use CD928+ on the road, but in the bathroom, you will definitely regard it as a piece of Lux soap. CD928+ is a real all-Chinese mobile phone! Not only editing short messages can be input in Chinese; Even the phone book can enter Chinese names. In the process of mobile phone culture, CD928+ is a well-deserved hero. The weight of CD928+ is 2 10g, and the circumference is 122× 54× 22mm. Colors are champagne, Galaxy Grey and Athens Black.

Voice control function can be said to be the most complete in mobile phones. This 6688 is made of popular silver, and the whole machine looks upscale and lively, measuring 105× 42× 17mm, with a weight of only 88g.

The first mobile phone with built-in Bluetooth function: Ericsson T39mc

Bluetooth is a short-distance wireless communication standard jointly developed by mobile communication company and mobile computing company, and its transmission range is about 10 meter. It is used to design and establish small, economical and short-distance wireless links between portable computers, mobile phones and other mobile devices. In order to develop Bluetooth technology, Ericsson initiated a Bluetooth alliance, including Nokia, Ericsson, IBM, Intel and Toshiba. Bluetooth technology operates in a unified frequency band, and the wireless data transmission rate can reach 720bPs to 1Mbps by using this technology. Bluetooth technology contains a complete set of encryption and authentication mechanisms, so it has

Strong security. The transmission distance of Bluetooth determines that it can be used as a small LAN terminal device to exchange data with other indoor or personal wireless devices. Bluetooth has always existed only as an optional accessory for Ericsson mobile phones. However, in August of 20001year, Ericsson finally released the world's first mobile phone T39mc with a built-in Bluetooth chip. This mobile phone is also Ericsson's first mobile phone that supports GSM tri-band and GPRS high-speed Internet access, and has advanced personal information management application (PIM), which is quite powerful. T39mc weighs about 86g, and its appearance is similar to T29. There are three colors: rose white, classic blue and lavender purple.

The first three-proof mobile phone: Ericsson R250PRO

The first WAP mobile phone: Nokia 7 1 10

Do students still remember our knowledge of productivity in Grade Three? It has promoted the development of human society and the continuous progress of science and technology. In fact, the development of mobile phones is also due to the development of productivity. When the mobile phone entered the GSM era from the analog era, the major brands of mobile phones developed rapidly and the competition was fierce, which made the mobile phone develop faster and faster. The 2.5G era and 3G era have also appeared one after another, and now they have gradually jumped into the CDMA era. This system was invented by China, which represents the great progress of science and technology in China. All this confirms what Deng Xiaoping said: Science and technology are the primary productive forces, and scientific and technological progress is the decisive factor of economic development. Productivity is the ultimate decisive force of human activities. Although China's mobile phone brand has not been fully recognized by people, we are confident that we will be able to build a world-class brand through our efforts in the future.

In fact, the history of mobile phone development not only represents the progress of science and technology, but also witnesses the development of human civilization. From analog to GSM, from GSM to GPRS, from single frequency to dual frequency, from English menu to Chinese input, from voice to short message, the development speed of mobile phone is increasing day by day. The above-mentioned mobile phones have played a dividing point in the history of mobile phones, especially in China. The adoption of every new technology has greatly promoted the development of mobile phones, so let us always remember their names.
