What do 1G, 2G, 3G and 4G mean? With the advent of the 5G era, what changes will happen to our lives?

From 1G to 5G, this refers to the upgrade of mobile communication technology, and the upcoming 5G is the fifth generation. The first generation of communication technology from 1986 marks that we have officially entered the era of mobile communication. After just over 30 years of rapid development, our way of life has undergone tremendous changes, which not only provides us with convenient communication, but also brings us a variety of entertainment methods. Let's review the development of mobile communication.

First, the 1G era, the mobile era. The earliest cellular telephone system standard in the United States adopts analog modulation technology, which can only make voice calls, and the calls are easily disturbed and eavesdropped.

Second, the 2G era, the digital telephone era. There are two main standards, GSM and CDMA. The biggest difference between them and 1G is that they use digital signal modulation technology, which makes the call stable and not easily disturbed, improves security, and introduces short message function.

Later, GPRS data service was developed on the basis of GSM communication system, which allowed us to surf the Internet on mobile phones, but most of them chatted with QQ on mobile phones, and only a few words and pictures could be transmitted. At that time, 5 yuan per month was enough for most people to spend 5 meters on traffic.

Third, 3G era, mobile multimedia era. There are mainly three standards: TD-SCDMA, WCDMA and CDMA2000, which support greater access bandwidth and capacity. The popularity of smart phones has also brought us into the era of mobile multimedia. We can not only make phone calls and send text messages, but also browse various websites directly on mobile phones, and many computer applications are gradually transferred to mobile phones.

Fourth, the 4G era, the era of high-speed Internet access. There are mainly TD-LTE and FDD-LTE standards. The biggest difference with 3G is that the network speed is obviously faster, about dozens of times that of 3G. Thanks to the rapid increase of network speed, various mobile media platforms are also developing at a high speed. Everyone can become the media, and online celebrities with mobile phones can be seen everywhere.

Fifth, the 5G era, the era of Internet of Everything. The 5G network has ultra-high network speed and lower delay, which provides a foundation for VR/AR technology and various cloud services. These industries will all shine in the coming 5G era. In addition, the business scope of operators in the 5G era is not limited to traditional voice and data services, but will extend like various Internet of Things industries, such as manual driving and telemedicine, which will become possible in the 5G era.

To sum up, every upgrade of mobile communication technology has brought great changes to our lives, affecting our food, clothing, housing and transportation. At present, the real 5G era has not yet arrived. As for what changes will be brought to our lives after the large-scale popularization of 5G, it is still unknown. Let's look forward to it!

1G, 2G, 3G and 4G are all followed by a letter g, where the letter g indicates which generation. 1G is the first generation and can only make voice calls. 2G is the second generation, which adds the function of sending messages. 3G is the third generation, and its biggest feature is high-speed data download. In addition, the video call function is also realized. 4G is the fourth generation, which is what we use now. The transition from 2G to 3G is the most remarkable, which has a great impact on people's lives and thoughts.

With the advent of the 5G era, our lifestyle and some habits will be subverted. There will be too many changes in detail. Let me talk about those that are closely related to our lives.

With the advent of the 5G era, our mobile phones should be updated once. In the past, the update of mobile phone depends on mobile phone, but this time it depends on the update of network. Although the shape of the 5G mobile phone will not be different from that used now, it will still be replaced with a 5G mobile phone. In the 5G era, the network speed will be greatly improved, and the tariff will be greatly reduced. There is no problem of insufficient traffic.

4G network is the video age, and 5G network is the Internet of Everything. If the 4G network is a cube, then the 5G network is a complete cube. Inquiring about the express logistics information in the 4G era, you can only see where it went. The 5G era will be more specific, and you can see the real thing when you leave the library.

Before the concept of 5G, it is not difficult to find that everything is moving towards intelligence and interconnection. 5G is more like an implementer, implementing the concepts put forward by people in the 4G era. Make what 4G does more perfect and sustainable.

At present, we live in the 4G era, and we don't feel the great changes between generations. Nokia came out in the 2G era, Apple came out in the 3G era, and Xiaomi came out in the 4G era. The competition in the 5G era is still strong. Whoever can grasp the current enthusiasm and launch innovative products will become the king of the 5G era. We just need to remember this: no matter how technology changes, it is always formulated around people.

Before we know 1G, 2G, 3G, 4G and 5G, we need to know "g" first. "G" is the abbreviation of generation, which means "generation". From 1G to 5G, it refers to the upgrade of mobile communication technology, an iterative process.

1G is the first generation. 1G adopts analog communication technology to solve the problem of voice transmission, but it can only talk and has poor anti-interference performance. The typical representative is the mobile phone. 2G is the second generation, which adopts digital communication technology. Due to the progress of technology, the anti-interference ability of 2G is greatly improved compared with that of 1G, which makes the mobile phone not only support making phone calls, but also send text messages, surf the Internet and so on. However, the network speed is relatively slow, and the representative company in the 2G era is Nokia. 3G is the third generation, with CDMA as the mainstream, which expands the spectrum, improves the spectrum utilization rate and makes mobile phones surf the Internet faster. Humans began to enter the era of mobile internet, and smart phones began to become popular. 4G is the fourth generation, and the biggest difference from 3G is that the network speed is obviously faster, which is about dozens of times that of 3 G. It has entered the era of high-speed internet access, which has spawned emerging industries such as live broadcast and self-media. Scanning code payment has become popular, and people's lives are increasingly inseparable from mobile phones.

5G is the fifth generation, which has the characteristics of ultra-high network speed, lower delay and ubiquitous access. These characteristics of 5G network will provide high-speed network support for VR/AR technology, which will undoubtedly promote the development of VR/AR ecology and make manual driving and telemedicine possible. In addition, with the popularity of 5G, it will promote the development of smart homes, truly enter the homes of ordinary people, and make our lives more convenient. 5G realizes the communication between people, things and things, and realizes the interconnection of everything.

2. 1G is an analog communication technology to solve the problem of voice transmission; The 2G era is a digital communication technology, which solves the problem of text transmission. The arrival of 3G represents a brand-new era. Mobile communication has become the carrier and infrastructure of the Internet, and human beings have begun to enter the era of mobile Internet. E-commerce and various new economic models began to emerge one after another. In the 4G era, the transmission rate of mobile communication has been greatly improved, which has brought the video era and changed the whole economic form and everyone's communication mode. 5G represents the arrival of the Internet of Things era, and it also represents that human beings have officially entered the digital era. 5G solves the problem of data transmission between things, which is the era of Internet of Everything. Mobile payment is the primary application of the Internet of Things. In the future, almost all products will be connected to the database through sensors. To exaggerate, if you buy clothes without paying taxes, you can't wear them on the street, because you will be reported to the tax bureau immediately to arrest you! The United States has surpassed 5G to develop 6G, which has solved the problem of data transmission between people and things and communication satellites (satellite networking). In fact, satellite networking is nothing new. GPS has been realized for a long time, but it was used in the vertical field before!

3.4G has changed the economic form, 5G has changed the social form and 6G has changed the lifestyle. The significance of mobile communication technology iteration to society is not only the improvement of network speed, but the arrival of artificial intelligence era. The future is the era of the Internet of Everything. Smart cities, driverless cars, digital commerce and even interstellar travel will all become a reality, which requires links between people and things or between things, and to realize them, stronger wireless data networks are needed as support.

Modern people can't live without mobile communication. From the era of 1G voice, the era of 2G characters, the era of 3G pictures, the current era of 4G video and the coming era of 5G, it is a magnificent communication history.

1G is the first generation mobile communication system, which adopts analog communication technology and comes from American aerospace and national defense applications. The masterpiece is the mobile phone in Hong Kong movies in the early 1990s.

The representative company of 1G era was Motorola, which was the leader of analog communication technology at that time. Unfortunately, a generation of giants failed to follow the market transformation and eventually collapsed.

1G adopts analog communication, which has some defects such as serial number and stolen number.

The second generation mobile communication system 2G changed from analog communication to digital communication, which solved the problems of confidentiality and signal instability of analog communication.

There are two standards in the 2G era, GSM in the European Union and CDMA in Qualcomm. Because the first generation of communication technology standards were in the hands of Americans represented by Motorola, the European Union was unwilling to lag behind the United States, and finally came up with the GSM standard, which completely surpassed the United States in the 2G era. At that time, Qualcomm had CDMA standard, but few countries supported it.

The representative company in the 2G era is Nokia, which can browse the content of WAP website with its own browser, mostly text content.

3G is the third generation mobile communication system. Compared with other countries, China entered the 3G era relatively late, and the 3G era only stayed in China for a short time. 3G network can increase communication frequency, transmit more data and support video calling.

There are three standards in 3G era, WCDMA, CDMA2000 and TD-SCDMA, among which WCDMA is the most mature and widely used. China's independent TD-SCDMA has some problems, but it is of great significance. China has more say in mobile communication standards.

The representative companies in the 3G era are the rise of Apple and the popularity of smart phones. On June 9th, 2007, 65438+1October 9th, Jobs released the first generation iphone, which cancelled the traditional keyboard, used multi-touch and creatively used the app store.

4G, the fourth generation mobile communication system, is the era we live in now. It has the characteristics of high speed, flexible communication and high intelligence, so it has spawned many new applications, such as scanning code payment, Tik Tok, Aauto faster and so on.

The era of 4G is the era of smart phones. The coverage of 4G signals is very extensive, and people's lives are increasingly inseparable from smart phones.

5G is the fifth generation mobile communication system, which has the characteristics of high network speed, low delay and ubiquitous access, and has realized the "Internet of Everything".

According to the 5G standard, the theoretical speed of 5G has reached 10 Gbps, and it can reach 1 Gbps in practical application, which is used to develop applications such as autonomous driving, smart cities and industrial Internet.

According to the requirements of the Ministry of Industry and Information Technology, the three major operators will realize the official commercialization of 5G networks in 2020, and it will take more than 1 year for 5G to meet us.

2G has realized the 1G analog era into the digital era, 3G has realized the 2G voice era into the data era, 4G has realized the integrated IP, and the data rate has been greatly improved. 5G realizes the communication between people, things and things, things and things, and realizes the interconnection of everything.

1G and 2G have little difference. When we know "G", it should be 3G, which is the third generation mobile communication technology. It is communication technology.

The earliest 1G was born around 1978 and was first invented by Motorola and Bell Laboratories.

This generation of communication system is an analog communication system with poor anti-interference, poor voice quality and high price, so it has not been widely used.

2G (second generation) stands for the second generation mobile communication technology. Stands for GSM. With digital voice transmission technology as the core.

3G services can simultaneously transmit voice (call) and information (e-mail, real-time communication, etc.). ). The representative feature of 3G is to provide high-speed data services, and the rate is generally above several hundred kbps.

2001April 16, the first 3G telephone in Britain was dialed through Vodafone network.

The download speed of 4g can reach 100Mbps, which is 2000 times faster than the current dial-up Internet access, and the upload speed can reach 20Mbps, which can meet the requirements of almost all users for wireless services.

5G With the development of the times, the Internet and artificial intelligence have been in the development stage. The opening of the 5G era means the rise of artificial intelligence (including smart homes and unmanned aircraft). ), that is, technological life.

G in 1G, 2G, 3G and 4G is the abbreviation of generation, indicating which generation of communication technology. For example, the English full name of 4G is the fourth generation mobile communication technology. The following is a brief introduction to these communication technologies:

I. First Generation Communication Technology (1G) The core of this generation of communication technology is the adoption of analog modulation technology, so the communication network established in this way can only carry out voice calls, telephone signals are easily disturbed, and the call quality is very unstable. At that time, there were only two network standards, namely TACS in Europe and AMPS in the United States. It can be said that the communication standard at this time is in the hands of Europe and America, and the representative product of this period is Motorola 8000X, commonly known as Motorola.

Second, the second generation of communication technology (2G) This generation of communication technology adopts digital signal modulation technology. Compared with 1G technology, the call stability is greatly improved, the communication security is also guaranteed, and it is not easy to be eavesdropped; 2G technology not only supports voice, but also begins to support the function of sending text. During this period, texting has become an important way of communication. On the basis of GSM system, 2G began to develop GPRS data function, that is, Internet access function. I believe that most people started to get in touch with mobile phones to surf the Internet from this period. At that time, the mobile company's monthly traffic package of 30 meters allowed us to use it for a long time. The technical standards in this period mainly include TDMA and CDMA. The representative products in this period are Nokia 7 1 10.

Third, the third generation communication technology (3G) era is also called the mobile multimedia era. 3G communication network can support higher bandwidth and network speed, smart phones have gradually entered people's lives, and mobile Internet has begun to flourish. The technical standards of this era are TD-SCDMA, WCDMA and CDMA2000, but the patents of 3G technology can be said to be monopolized by Qualcomm, and Qualcomm made a lot of money by collecting patent fees. In the 3G era, Apple began to launch the IPhone series, and domestic mobile phone manufacturers Lenovo, Xiaomi and Meizu also began to enter the smart phone market.

Fourth, the fourth generation communication technology (4G) The 4G era has brought the era of high-speed networks. Compared with 3G, the network speed is faster and the traffic is cheaper, resulting in many new industries, such as live broadcast, mobile games and self-media. The technical standards of this era are TD-LTE and FDD-LTE. Up to now, although the mobile phone communication technology has developed for four generations, China has not mastered the relevant standards and patents. We just follow the footsteps of the United States and Europe step by step, while the communication companies in the United States and Europe have made a lot of money from China through standards and patents. Therefore, China also attaches great importance to the development of the next generation communication technology 5G.

Finally, in the 5G era, the changes brought by this communication technology are revolutionary. Due to the high-speed and low-latency characteristics of 5G network, a large number of new industries will be born, such as driverless, telemedicine, Internet of Things and so on. It will make VR/AR technology no longer stay in words. Therefore, 5G technology will not only be a communication technology, but also an infrastructure, and our life will change accordingly.

Looking back on the development of the fourth generation communication technology, we can find that the development of communication technology is closely related to a country's high-tech industry. It can be said that whoever has mastered the information technology standards and patents will have an advantage in the future development, which is also the fundamental reason for the 5G competition between the United States and China, and Huawei, the representative company of 5G technology China, is undoubtedly the target of key sanctions in the United States.

The most obvious change is the improvement of network speed. We can't underestimate the role of network speed-up. Quantitative change leads to qualitative change. When the network speed reaches the theoretical speed of 5G, our social life will undergo great changes.

After the network speed reaches a certain speed, the application of wireless communication will be more extensive. For example, the construction of smart cities, the Internet of Everything and the development of AR/VR ecology all need the support of high-speed networks.

What directly affects our ordinary life may be smart home. Limited by the network, today's smart home is still at a superficial level. The popularity of 5G will promote the development of smart homes, truly enter the homes of ordinary people, and make our lives more convenient.

Generally speaking, it is the high-speed network that connects people and things and exchanges information. The Internet of Everything is an irresistible trend. Let's get ready to hug it.

We are familiar with 2G, 3G and 4G, representing different communication technologies.

G is Generation, which means "generation" The definition of 1G~5G is mainly from the perspectives of rate, service type, transmission delay and various handover success rates.

1G era is a phonetic era, that is, it can speak and has poor anti-interference performance. At the same time, the frequency reuse and system capacity are not high by simply using FDMA technology. The mobile phone of that year was a typical representative.

The second generation mobile communication technology adds more multiple access technologies, including TDMA and CDMA, and 2G is digital communication, so the anti-interference ability is greatly enhanced. The 2G era is a writing era, which uses digital transmission instead of analog to improve the efficiency of telephone network search.

In the 3G era, data packets including voice, video and other multimedia content can be transmitted through the Internet, which can handle images, music, video and other media, and provide services such as e-commerce and video calling.

At present, 4G is the fastest in all networks. Theoretically, the downlink peak can reach 100Mbps, which can transmit high-quality video images. The main standards are LTE, TD-LTE and FDD-LTE, which have been widely deployed by global operators. And can meet that service demand of people for all wireless services at present.

With low latency, low power consumption and high reliability, 5G is an evolutionary integrated solution for various wired and wireless access technologies. The download speed in the 5G era is faster, which can serve all kinds of applications that need high-speed network.

Next year, 5G will be officially commercialized, and the 5G era will bring great changes to our lives, including key applications such as the Internet of Things, the Internet of Vehicles, driverless, smart medical care, VR/AR, and Industry 4.0. This will make great changes in our lives, and we look forward to the real arrival of the Internet of Everything era.

Recently, the concept of 5G is as hot as artificial intelligence, and it is the fiery of 5G that has created the concepts of 1G, 2G, 3G and 4G. What was not popular in the past was also mentioned.

From 1G to 5G, it refers to communication technology. People should communicate, people should communicate with things, things should communicate with things, and everyone should communicate. Since we want to communicate, we should make some communication equipment and develop communication software. The most common communication equipment is mobile phones, as well as outdoor base stations and computer rooms. Whether these devices or software, we must rely on human wisdom to make. Human wisdom and knowledge is communication technology.

Now it has developed to 5 G. Compared with the previous G and 5G, the communication frequency is better and the communication wavelength is shorter, so the base station needs to be changed and the receiving antenna of the mobile phone needs to be changed.

The changes that 5G has brought to our lives can be imagined. One is the increase of download rate, and the other is that the Internet of Things will usher in greater development.

What improves the speed is the speed of surfing the Internet on mobile phones. On weekdays, the most things we do with mobile phones are watching news, watching videos and listening to music on the Internet. What we are most afraid of is that the internet can't be opened. If we turn around in a small circle, we will know that the internet speed is not good again. 5G will greatly increase the Internet access rate.

In terms of the Internet of Things, the Internet of Everything will be realized in the 5G era. The high speed, many connected devices and wide coverage of 5G network have laid a good infrastructure and technical foundation for the Internet of Things. Maybe it's not a dream for zoo keepers to monitor the health of lovely animals remotely.

Although 5G has not been popularized, we can imagine how much changes the future 5G era will bring to our lives. What do you think, friends?
