Let’s talk about the communication industry I have worked with this article with everyone. Recently, the proliferation of information in all aspects, including chatting with Huawei’s classmates, really feels a lot of emotions. Think about my own undergraduate majoring in communication projects, graduate posting information and communication engineering, and have studied history and professional courses in communication from undergraduate. Later, after the school recruited communication companies Essence Well, talk about it! In fact, at this time at this time, looking at China’s communication industry, in fact, it is really not bad. At least the 5G era is in a leading state. Our communication industry has gone through decades of development and changes. Many people may not know much about the development history of the road and the story of a generation of communications from generation to generation, which is also about to be explained below. It the earliest time to talk about Chinese communications, of course, the era of fixed -term passwords, that is, the age -control switch era mentioned in the course of communication engineering. Because during this period, all the communication equipment used in China depends on imports. After all, the key core technologies are controlled in the hands of developed countries such as the United States, Europe, and Japan. Therefore, in the 1980s, a concept of popular communication industry at that time was called “seven nations and eight systems”. Fujitsu, the United States’ Langxun, Nortel for Canada, Ericsson in Sweden, Siemens in Germany, Belgium BTM, and Alcatel in France, and ZTE and Huawei have only sprouted and established in Shenzhen in the mid -to -late 1980s. It today, our parents should remember it. How can it be installed in my home in the 1980s and 1990s, because it only costs tens of thousands of yuan to install only one fixed -line. The reason for the cost is that all communication equipment at that time relying on imported, high installation costs and communication tariffs, it was a very luxurious thing to have a family fixed phone call. This situation continued until 1990. The first digital switch ZX500 developed by ZTE in my country was gradually breaking the technological monopoly and barriers of Western in the West. The remembers to participate in the company’s training after recruiting the job at that time, and I have heard some fun things. For example, on a communication device we bought from others at the time, a piece of iron was broken and we needed to be replaced, and we needed to spend dozens of dollars to others. To bid abroad, our Chinese communications company has made a variety of exquisite PPT films to tell customers the business, technology and services provided by our Chinese communications companies. The PPT film shows a world map and the map full of small red flags that indicate their products … This is the age when our communication industry is divided! The so -called 1G era is what we call the “Big Brother era”, which occurred in the late 1980s and early 1990s. The so -called 1G communication is practical to simulate communication technology, and the communication rate is very low. In this era, our mobile communication industry was almost in a blank stage. It was not until November 1987 that Guangdong opened the first mobile communication network in the country. Only for the first time in the Chinese mainland market, there was a brick -size mobile call terminal. Also known as “Big Brother”. It was not until mid -2001 that the simulation network transferred network was launched across the country before officially closed the 1G simulation mobile phone network. In the next 2007, we opened a new 2G digital communication era. Then someone will ask: From the 1G prelude of 1987 to the opening of the 2G era in 2007, for 20 years? Didn’t the product iterate? That is because there are various transition products and stages between 1G and 2G, including but not limited to the paging machine around 1998, IC phone calls around 2002, and small Lingtong around 2004. The communication protocols in the 2G era are mainly divided into two types, namely European GSM and the United States CMDA, and the communication rate is about tens of Kbps. Therefore, the 2G era is just Europe and the United States. Of course, China in this era has also begun to follow the trend of the world. is worth mentioning that the most well -known communications giant in this era is the beginning of Europe and Ericsson. After just ten years, Nokia became the world’s largest communication equipment dealer. I don’t know if you still remember it. At that time, there were almost all mobile phones in the streets and alleys. Communication, the third generation has more stable and faster transmission, and the diversification of services began to gradually present. In the 3G era, it can “compare” images and music quickly, but the main is the era of the picture. Between 144kbps-2Mbps. The 3G era Europe, the United States, and the middle and three parties, everyone noticed, China gradually began to participate in the standard formulation and obtained breakthroughs. European WCDMA, the US CDMA 2000, and China’s TD-SCDMA have become three main systems of 3G. Of course, the most important technology in the 3G era is CDMA, which holds a technology patent in Qualcomm. The CDMA shows huge advantages with the characteristics of large system capacity, high frequency utilization rate, strong anti -interference capacity, and soft capacity, soft switching. The end of 2008 in our country began to issue 3G licenses, but it was not popular until 3G terminals around 2010. At that time, we used mobile phones to chat with QQ, send text and pictures. I still remember that I was studying undergraduate at that time. Everyone used the Nokia N series slide mobile phones. Of course, the Android phone also gradually emerged, such as Motorola’s DEFY phone. At that time, the highest -end 3G mobile phone should be the iPhone 3GS released by Apple in 2009. of course, in the 3G era, the Chinese communications industry also began to usher in a breakthrough. The three major operators began to work. In 2009, China issued three 3G licenses, namely China Mobile’s TD-SCDMA, China Unicom’s W-CDMA and China Telecom’s CDMA 2000. Unicom, which is most widely used in the times), also has a trend of movement in the 3G era. It 2014 to enter the 4G era, and the 4G era was unified by LTE. In the 4G era, due to the large market size of the Chinese market, the three major operators (mobile, Unicom, telecommunications) vigorously promoted, creating the world’s largest 4G network. And the implementation speed of 4G is very fast, and the popularity is high. Before we have been looking forward to and brewing, we have used 4G equipment and terminals in our hands. of course, in addition to 4G, there is a 4G , 4G is a new generation of 4G network. It can be said that the upgraded version of the 4G network. The peak of the network speed has increased a lot. 50Mbps. 4G is the mainstream stage we are now. Our mainstream mobile phone supports 4G version. Since 2018, a series of keywords created by artificial intelligence, virtual reality, big videos, the Internet of Things, and other series of keywords. Created a few 5G networks to create and outside the field, and the 5G terminals have also appeared one after another (although the price of 5G terminals has reached the average level of 5 digits). At this time, I couldn’t help but think of a ridiculous paragraph on the Internet: “Ah, the 5G era, I forgot if the mobile phone network will go bankrupt all night.” There are many times of increased rates. The 5G, ZTE and Huawei are still very competitive. They are also the two major Chinese equipment vendors who can lead the outside world and lead the world. So summarized the development of China’s communication industry in the past 30 years. We have gone through the glorious road of 1G blank, 2G followers, 3G breakthroughs, 4G parallel, 5G lead. It’s still amazing and proud! The people think of mobile phones when they hear Huawei and ZTE. Every time there is news, everyone can buy Huawei mobile phones when they shout to support Huawei. It should be said that mobile phones are really just one aspects of ZTE and Huawei business. At best, it can only be regarded as a small part of the terminal business, and this is only the business of ordinary consumers. Compared with mobile phones, Huawei and ZTE have many very large business systems, and the services and solutions provided by various corporate customers, operators and customers, etc. are also numerous. , Light communication, multimedia, cloud computing, virtualization, and even a series of products and services in special industries such as energy. Ip communication equipment and products are actually a highly comprehensive integrated, involving a very long and long industrial chain. Including Huawei ZTE, they have no way to avoid the long industrial chain and dependence on the external parties. This must be a global cooperation to continue to win a win -win situation. Tesla’s innovation is amazing, but many models like the Model series have insufficient production capacity. Why, it is very strong to others; the Samsung Empire is extremely powerful, but if there is no ARM authorization, some chip manufacturing may also be manufactured. It will be affected; even if it is a mid -day Apple company, its advantage is that it is concentrated on the design of the operating system, ecological chain and whole machine products. It is also hindered that some partners estimate that the business will be blocked. There are too many chestnuts that can continue to develop this kind of global cooperation, and it is in one fell swoop. It, like the thing of ZTE, the people who tipped west there estimated that they were unprofessional, or even those who had not engaged in the communications industry at all. After all, any high -tech enterprise cannot be fully covered with upstream and downstream links, so it is necessary to look at this matter objectively and fairly. The people will ask when I communicate with me through the public account: What is the communication industry? Is it the sunset industry? I have signed a contract with ZTE or Hua, should I go? I think so that the communication industry is just that explosive growth period has passed, but it is definitely not a sunset industry. At least the 5G in front of me is very good. Everyone thinks too much. It, from the perspective of the development of the entire communication industry, Huawei and ZTE’s performance in the fierce domestic and foreign competitive environment are obvious to all, and Huawei and ZTE are one of the two worldwide two that can provide “end -to -end”. Solution company. Looking at the world, such as Bell, Bei Electric, Alcatel, Langxun, Motorola, Siemens, etc., where is it now? From a global perspective, Huawei, Nokia, Ericsson, and ZTE have giant communications industry’s multinational companies. It, the technology of communication companies is still very good. You can definitely learn things, whether it is business, technical, or standardized processes and standardized things. Even if it is not good, Huawei and ZTE are very good springboards. If you have made a choice, don’t think about it, work hard, you will definitely have your own sky!
