Wireless communication technology is updated almost every ten years.
At present, global operators are in the midst of 5G commercial deployment. As of November 2018, 182 operators around the world have conducted 5G trials, deployments and investments in 78 countries. China announced that it will start commercial trials in 2019 and promote commercial scale in 2020; South Korea is expected to start commercial scale in 2019; Europe will focus on industrial Internet exploration, and it is expected that individual radical operators will try commercial use in 2019. According to statistics, the first round of commercial use of 5G will cover one third of the world's population.
From the results, 5G will bring about different changes from the past, but most people still have some questions about 5G. These questions mainly come from the following aspects.
Do we need 5G?
In the 3G era, users' needs for mobile Internet have been met, and 4G network allows users to enjoy the convenience brought by mobile Internet anytime and anywhere. So, do we really need 5G?
First of all, China has the world's largest mobile market, and is an important participant and supporter of global 5G technology research and development and industrial innovation. China has always attached great importance to the development of mobile communications. In 2006, the State Council issued the National Medium- and Long-Term Science and Technology Development Plan. The 16 major projects identified include a new generation of mobile wireless special network, which fully supports the development of China's mobile communications. It achieved the breakthrough of 3G, the synchronization of 4G, the initial lead of 5G, and achieved the leading goal in some technologies and business fields, which laid the foundation for building a network power and manufacturing power.
Second, the ICT industry has been driven by supply rather than demand for a long time, but the situation has changed.
According to statistics, by 2025, there will be 100 billion connections worldwide, of which 55% will be concentrated in the commercial sector, such as intelligent production, smart cities, etc. The value lies in improving production efficiency and creating production efficiency. In addition, 45% of the connection applications in the consumer-oriented field of smart home, car networking, wearable devices, etc., will greatly enhance the quality of life of people. The connection of 7 billion people may only account for 10% of the total number of connections, and the vast majority of connections will be the connection of people and things, things and things. That is to say, 99% of the devices have not been connected so far.
With the development of smart cities, more demands are placed on the network, which is based on the number of connections, bandwidth and delay.
Based on this, 5G came into being. Based on the above requirements, 5G should have a number of connections of 100 billion levels, an ultra-low latency of milliseconds, and a communication rate of 10 Gbps compared to existing mobile communication technologies.
“4G changes life, 5G changes society.†Qiu Gang, deputy inspector of the Ministry of Science and Technology, said: “As the most important infrastructure in the Internet age, 5G will improve the quality of all industries and the new digital economy for the traditional economy. Transformation provides a technical premise and is a new kinetic energy for economic development."
5G is coming, where is 4G going?
The future network will be the state of long-term coexistence between 4G LTE and 5G NR. The China Telecom 5G Technology White Paper has an accurate description of 5G network evolution: "An important prerequisite for 5G network evolution is that 4G and 5G networks will coexist for a long time. Existing networks such as 5G, 4G, and WiFi can meet the needs of multiple scenarios to achieve indoor and outdoor network collaboration."
As mentioned before, 4G networks can meet the personal needs of current users, such as video and image transmission. Therefore, the application scenarios of the future 5G are more specific application scenarios such as industrial Internet, manufacturing, and intelligent driving. Both have the characteristics of long-term coexistence and coordinated development.
Zhang Zhiwei, chief marketing officer of Ericsson's Northeast Asia region, said: "You don't have to rely on converting 4G users to 5G users to develop 5G. Even if you don't replace 4G, 5G will find a differentiated place to live."
In addition, there is still a dispute about the market demand in the 5G rate. In fact, in the early 4G era, there were people who questioned the high rate. The facts show that after a period of development, there is no such thing as the relationship between supply and demand. The "waste" problem.
At the same time, it is worth noting that as user traffic demands continue to proliferate, the main challenge for 4G networks is not the speed, but the network capacity. 5G's first standard R15 focused enhanced mobile broadband (eMBB), introducing a wider frequency band and Massive MIMO technology, can make a thick network capacity layer without adding new sites, releasing the squeezed user traffic demand. Huawei's "All Bands Go to 5G" network evolution strategy, 5G deployment is not limited to C-Band and millimeter waves, Sub-3G spectrum also has the ability to evolve to 5G, to smoothly introduce 5G new capabilities, achieve 10 Double network capacity, 10dB coverage enhancement and 10x experience boost.
