In recent decades, science and technology have developed explosively, and some previously unimaginable technologies have appeared in life and spread to the public.

The emergence of smart phones has also changed our way of life.

Nowadays, we can learn about the world, taste delicious food, buy food and so on without leaving home. At the same time, all the software that can facilitate life is installed on the smartphone. When we go out, we can navigate to our destination without paying for it and asking for directions. All these conveniences show the progress of the times.

But in fact, this life didn't last long.

Many people are curious, when did smartphones become popular?

Let's look at the development of mobile phones. Come and have a look with me.

Mobile communication has a history of forty or fifty years. In recent decades, the mobile network has changed greatly from 1G to the current 5G. So how did the mobile phone become like this step by step? We started with the first generation of mobile networks.

1, first generation mobile communication (1G)

Mobile communication technology appeared as early as the beginning of the last century, and has been developing and progressing since then. It was not until the 1970s that the International Radio Congress approved the frequency allocation scheme for the 800/900MH band of mobile phones that the first generation of mobile communication (1G) officially entered the development period.

1in April, 973, marty cooper, a technician of the famous American Motorola Company, invented the world's first mobile phone for civilian use. It can use any radio frequency band to make calls.

1987, the first mobile phone entered the China market, the model was Motorola 3200. That is, everyone's mobile phones are extremely expensive, and a mobile phone may cost tens of thousands of yuan.

The first generation of mobile communication only transmits analog signals between mobile phones and base stations, which can only be used for making phone calls, and its security and anti-interference ability are relatively poor, so it cannot roam internationally.

At this point, the first generation of mobile communication has entered the life of the general public. Of course, because of its high price, only a few people can afford it, and it has not yet reached the point of popularization.

2. Second Generation Mobile Communication (2G)

In the 1G era, Motorola dominated the field of mobile communication, and then the arrival of the 2G era ended this situation. The 2G system is a GSM system in Europe and a CDMA system in North America. It is more secure than 1G, and its function is not limited to calling.

199 1 year 2G was officially commercialized, and 1995 really spread to all countries in the world.

Ericsson, Nokia and other brands are also rising, which is the era of rapid development of mobile phones.

Among them, Nokia mobile phone is deeply rooted in people's hearts, and its built-in snake game is a childhood memory of many people.

Around 2000, brands came up with various types in order to improve their competitiveness, such as flip phones, color screen phones, slide phones, dual-screen phones and so on.

This stage lasted for a long time, and mobile communication gradually took root in people's hearts.

3. The Third Generation Mobile Communication (3G)

3G came into being in 2002, but it was not until 2009 that our Ministry issued a 3G license that China officially entered the 3G era. The 3G standards used in China are WCDMA, CDMA2000 and TD-SCDMA.

Compared with 2G, 3G communication technology has been greatly improved, which can provide more advanced service functions, higher network capacity, faster transmission speed and realize wireless broadband access.

This era has to mention a brand that changes the situation, that is, Apple mobile phone.

In 2008, Apple's iPhone 3G came out, which opened the era of mobile Internet smart phones, and the contribution made by Apple's mobile phones was unprecedented.

In the same year, the first Android phone HIC G 1 was released, and two smart phone camps, Apple and Android, appeared.

Nokia and Motorola, which are unwilling to change, have been defeated by the times and the general trend has gone. More and more people begin to use smart phones, which has reached the level of popularization.

4, the fourth generation of mobile communication (4G)

2065 438+00 4G technology began to be put into large-scale construction. The transmission speed of 4G is faster, and it can answer language, data and streaming media "anytime, anywhere". Everyone can have a better and more stable video chat.

In 20 13, the Ministry of Industry and Information Technology officially issued 4G licenses to the three major operators, which means that China has entered the 4G era.

At the beginning of 20 14, the three major operators opened their 4G services to the public one after another, and the "4G" era came quickly. At this point, smartphones have become popular and cheaper.

The 4G era is an era of rapid development of smart phones. The rise of various domestic brands and the development of more black technologies have improved the user experience. At the same time, the rapid development of various application software has also changed everyone's lifestyle.

It can be said that by 20 13, smartphones have basically become popular and can be applied to every scene in life.

5. Fifth Generation Mobile Communication (5G)

20 19 10, the Ministry of Industry and Information Technology announced the official launch of 5G commercialization, and the three major operators also announced 5G commercial packages, which are much more expensive than 4G packages.

The speed of 5G network is more than ten times that of 4G network, and it also has the characteristics of low delay and high capacity. If the promotion is successful, the scene of the Internet of Everything can be realized.

Everyone must be familiar with it at this stage.

However, due to various reasons, 5G communication technology has not been popularized to the whole people, but globally, China's 5G has been at the forefront of the world, and we have mastered more core technologies!

It is believed that in the near future, 5G communication technology will be popularized in China for the first time.

It has been more than forty years since the first mobile phone was developed, which is summarized as follows:

1G era: since 1973, sound transmission has been realized through analog signals. Motorola is the market leader. It is called mobile phone in China.

2G era: 1995 is popular all over the world, and brands such as Nokia and Ericsson are rising. The functions of mobile phones are not limited to talking, but also digital.

3G era: China formally applied in 2009, and two fronts, Apple and Android, appeared, which means the rise of mobile Internet.

4G era: 20 13 China launched 4G, and smart phones began to spread to the public, which is characterized by faster and more stable connection between people and information.

5G era: From 2065438 to 2009, 5G technology was officially commercialized in China, which was more than 10 times faster than 4G, and could realize the interconnection of everything.

Smartphones have been popularized in China since 2009, and operators are vigorously promoting them, and the prices have also dropped a lot. During this period, not only adults but also children began to use them. By 20 13, 4G will be launched, which will basically spread to people of all ages in China.
