5G, how to change our lives ——Foresight on the development trend of the fifth generation mobile communication technology â– Huang Wuxing Duan Qingma Rui Primer Wake up in the morning, the bedroom lights and air conditioners automatically turn on; when you come to the bathroom, the face wash water is automatically adjusted to the appropriate temperature, the digital toothbrush records and uploads the real-time data of the teeth and the mouth; after breakfast, enter a few instructions, the car will take You are driving on the road automatically, you have already opened a teleconference in the car... The above scenes may be the daily life of the 5G era. In November 2016, Huawei's “Polarization Code†program was approved by the International Mobile Communications Standardization Organization. While praising Huawei, everyone feels deeply that the embarrassing 5G era is no longer a distant future, but a time of progress. Meet the "traffic storm" 5G, as its name suggests, is the fifth generation of mobile communication technology. Some people may ask, 4G is fast enough, why do you start to develop 5G now? Although 4G can meet the current network needs, with the rapid development of artificial intelligence, smart home appliances, driverless, production automation, and intelligent services will enter our lives. Personal products, urban infrastructure, and factory machinery will be Connected to the mobile network, the informationization of the whole society will be more thorough and thorough, and the information flow will also explode. According to the prediction of authoritative organizations, by 2020, the network will have to accommodate 200 billion class equipment or machines. Only smart city, intelligent transportation and industrial automation need to connect nearly 30 billion devices. With so many devices inrush, the network capacity must be infinite, and the rate must be high enough to ensure high network reliability. In order to realize these 5G skills, the technology will be "soft and hard". For example, software technology should further explore the spectrum resources, similar to “changing small water pipes into large water pipesâ€, and develop ultra-high frequency to obtain more bandwidth and achieve “hurricane†speed. On the hardware, the low-frequency diffracting ability used in the past is not bad. The influence of hiding in the corner is not big, but the 5G UHF is almost straight-line, and the corner is likely to be a signal dead angle. This requires the traditional macro base station to become a site. More and denser micro base stations. In the 3G and 4G era, we can always be patient, the network speed is slower, etc., the signal is not good, I change the place to call. But in the era of Internet of Things, the machines on the Internet can not have such good patience. Can't the intelligent traffic in the whole city be paralyzed because of the excessive red packets and the surge in traffic during the Spring Festival? Obviously, to achieve the future "traffic storm", the "Gale"-like network speed like 4G is far from enough, and it is necessary to have a "hurricane" to be able to handle it. It is extremely urgent to develop a new generation of mobile communication technologies with higher speed, larger capacity and lower latency. Accurate telemedicine can be provided using 5G networks. What are the magical powers of 5G? Speaking of 5G's ability, everyone must think of its ultra-fast speed. However, if it is only this, it will be too small. In the 5G concept white paper released by China, experts summarized the future development trend of 5G into four aspects: continuous wide-area coverage, hot-spot high-capacity, low-power large connection and low latency and high reliability. A summary of several numbers is 1000 times capacity increase, 100 billion+ connection support, 10 GB/s maximum speed, and 1 millisecond latency. In general terms, it is "anything can communicate" "more people are not afraid" and "unparalleled fast" "the best experience goes hand in hand". Specifically, continuous wide-area coverage means that 5G can enable people to access high-speed Internet in harsh environments such as remote areas and high-speed mobile. Hotspots and high capacity enable 5G to meet the requirements of people who can enjoy extremely high network speeds in areas where personnel are dense and traffic demand is high. The low-power and large-connect feature makes 5G play a role in smart weather, environmental monitoring, intelligent agriculture, forest fire prevention and other applications that target sensing and data acquisition. For areas such as car networking, driverless, and industrial control that have extremely high requirements for delay and reliability, low latency and high reliability may enable 5G to cope with it. The future is no longer far away from us Since 5G contains huge economic and strategic interests, countries such as Europe and the United States hope to occupy the leading position in technical standards and conduct technological research and development and layout. As early as November 2012, the EU has initiated a total investment of 27 million euros to develop 5G technology. The United States, South Korea, Japan, United Nations operators and telecommunications equipment manufacturers have carried out corresponding technical research and industrial layout. On May 31, 2016, at the first global 5G conference held in Beijing, the 5G standards development agencies of all countries disclosed the latest developments in their respective research and development. US telecom operators announced in early December 2016 that they will provide the first 5G trial operation service. One of Japan's goals is to use 5G services during the 2020 Tokyo Olympics. South Korea's 5G commercial process will be based on the 2018 PyeongChang Winter Olympics. Key time node. The emergence of 5G not only provides a powerful new generation communication network technology, but also will trigger a revolution in communication technology of "Internet of Everything". Virtual reality, online games, smart home, smart medical, intelligent education and other industries will Driven by 5G, it will revolutionize our way of life. On the day when 5G is really popular, people may no longer need hard drives and CPUs. They only need one monitor and network card. All background data is processed by the cloud. The high-capacity and high-speed features can bring virtual reality into life and practical applications. in. Due to its low latency, large bandwidth and high link density, 5G is considered by the industry to be a key technology for autopilot and car networking communications. The real-time remote control realized by 5G has high precision and high-speed transient response, which can realize remote driving and even automatic driving of the Internet. The 5G network can also provide a telemedicine platform, and implementing precise remote surgery will no longer be a fantasy. 5G leaves us with too much imagination and expectation, let us wait and see.
