What technologies can be enabled with 5G? What are the three major technologies of 5G?

The deployment of 5G began in Japan a year ahead of schedule, and the area around 5G, the next-generation mobile communication system, has become busy. Japan has been heading towards 2020, but it has been moving forward for a year, and services will begin in 2019. According to Japanese news reports, the three major operators of NTT Docomo, KDDI and SoftBank will start limited services by lending 5G-compatible terminals and use them on user-owned smartphones from 2020.

NTT Docomo plans to provide free 5G handsets at the Rugby World Cup Japan Championship, which will be held in the fall of 2019, and Rakuten, Rakuten's first career as the fourth airline, is expected to launch 5G services in 2020. By 2020, you can enjoy state-of-the-art 5G services at the Tokyo Olympics venues. It will be released in the United States starting on October 1.

Japan's 5G release was by no means a global early one. In some parts of the U.S., Verizon launched Verizon 5G Home, the world's first commercial 5G service, on October 1. Although it is not a mobile device but a home broadband service, it is surprising to be able to communicate at fiber speeds equivalent to 300Mbps and a maximum of 940Mbps.

Of course, Verizon will eventually start offering mobile services, and other carriers in the United States are preparing for this service. Finally, we completed the development of 5G, which is the successor to 4G, which is currently widely used in Japan, and corresponds to the fifth-generation mobile communication system. Specifications are being considered through an event called the Third Generation Partnership Program, in which standardization organizations from around the world participate.

This became the standard specification for 5G New Radio in June 2018, and the content was finalized. The launch of the 5G service in Japan has also been affected by stricter technical specifications, as well as the fact that the service has started in the United States. The 5G business service is scheduled to be launched in China and South Korea in 2019 and features ultra-high speed, ultra-low latency, and multiple simultaneous connections.

Since 5G is a technology developed from 4G, the communication speed is naturally high. It is an easy-to-understand feature until now, every time I transition from analog type 1G to digital type 2G to 3G, 3G to 4G, the call quality is getting better and better, the audio is getting beautiful, the ** speed of the application is getting faster, and the time is getting faster and faster I am able to experience the effect without being burned. Wireless communication traffic continues to increase due to the increase in mobile subscribers and the increase in services that process large amounts of data.

In order to solve this problem, it is necessary to increase the speed of communication. In fact, the development of mobile communication systems has been focused on this acceleration and large capacity. 5G adds to this requirement for ultra-fast, low latency, and simultaneous connectivity.

The main advantage of 5G networks is that the data transfer rate is much higher than that of previous cellular networks, up to 10Gbits, which is faster than current wired internet and 100 times faster than previous 4G LTE cellular networks. Another advantage is the lower network latency (faster response time) of less than 1 millisecond, compared to 30-70 milliseconds for 4G. Due to faster data transfers, 5G networks will not only serve mobile phones, but will also be general home and office network providers, competing with cable network providers.

One of the major features of 5G is to serve the "Internet of Things", and the development of mobile communication is initially applied to the needs of communication between people, and then to the service application of accessing high-speed networks, which are inseparable from people.

5G has changed the old communication purpose and technology, making the application of the "Internet of Things" more thorough.

Although LTE-V, NB-IoT, and LoRa are widely used IoT technologies, they are not enough to support the "Internet of Vehicles".

5G is the accelerant of the Internet of Vehicles technology, and the large bandwidth, extremely low latency, massive number of connections, and tight coverage are the ignition points of the Internet of Vehicles. The top domain name was also registered.

Although the main application scenario of 5G is for the Internet of Things, it is not completely unusable.

5G is an extension of 4G, and BAI is the fifth-generation DU mobile communication standard, also known as the fifth-generation DU mobile communication technology. 5G has the characteristics of high-speed ZHI, low latency, and large capacity.

In terms of high DAO speeds, 5G's network speed is more than 10 times faster than 4G. In the case of a good 5G network environment, a 1G movie can be finished in 1-3 seconds, and basically it will not exceed 10 seconds.

In terms of low latency, the human blink time is 100 milliseconds, while the latency of 5G has reached the millisecond level, which is only one-tenth of that of 4G.

In terms of large capacity, the 5G network connection capacity is larger, and even if 50 customers are online at the same time in one place, they can experience a speed of more than 100Mbps.

aspects of life. According to the Ministry of Communications, 5G communication technology can greatly reduce energy consumption while increasing data transmission rates, which can increase the battery life of low-power batteries by more than 10 times. That is, in the true sense, the "Internet of Everything" can be realized.

With the increase of transmission speed, the concept of the Internet of Things will gradually enter every home. At that time, it is becoming more and more common for a mobile phone to control everything in the house. After the realization of the Internet of Everything, it will improve people's life and office efficiency qualitatively.

Education and healthcare.

5G communication technology can realize ultra-high-speed processing of massive data, which greatly promotes the in-depth application of artificial intelligence technology. One of the main applications of AI is education and healthcare. Expert Prediction:

With the development of artificial intelligence, 5G will be applied to education and medical care in combination with artificial intelligence. Especially in the early education industry, it is always difficult for the previous robot to respond to the instructions or actions issued in a short time due to the influence of information transmission speed. Similarly, in medical care, the application of artificial intelligence in the 4G era is very limited, and the largest application can only be to take care of the elderly.

If in the 5G era, the speed of information transmission is faster, and the response of robots will be correspondingly faster, which will bring great changes to the education and medical industries.

Transportation. 5G communication technology can realize ultra-high-speed processing of massive data, which greatly promotes the in-depth application of intelligent technology. The same applies to transportation.

I believe that everyone has heard of unmanned technology in the 4G era. However, the efficiency of 4G data processing is really limited, so that unmanned driving technology has not been truly applied. In the 5G era, I believe that through efficient information transmission, there will be more and more unmanned cars on the road, and the incidence of traffic accidents will plummet.

Military aspects. According to relevant military experts, 5G communication technology will likely allow the military to have dedicated frequencies. Because 5G communication technology not only makes full use of existing communication resources, but also expands to millimeter wave communication resources, it is possible for the military to have specialized frequencies.

This will effectively solve the existing problems of overlapping and sharing of frequency bands between military mobile communication systems and civilian mobile communication systems, and mutual interference. More importantly, 5G will promote the interconnection of the most advanced platforms in the whole battlefield. 5G communication technology can enable more users to communicate with the same frequency resource, thereby greatly improving the efficiency of frequency application without increasing the density of base stations.

Although the 5G era is still in the future, we are still very well prepared. I also hope that everyone will join in the construction of the 5G era and contribute their own strength.

5G technology was developed first by South Korea. On May 13, 2013, South Korea's Samsung Electronics announced that it has successfully developed the core technology of the fifth generation of mobile communications (5G). In April 2019, South Korea became the world's first 5G country, and in September of the same year, Huawei officially released the Mate 30 to support 5G.

The fifth-generation mobile communication technology, referred to as 5G, is a new generation of broadband mobile communication technology with high speed, low latency and large connection, and is also the network infrastructure that realizes the interconnection of man-machine mega-abrasives.

5G adopts a full-service design, modular network functions, supports on-demand calls, and realizes function reconstruction. By adopting the service-oriented description, easyMarkets is conducive to the introduction of IT development capabilities and the potential of the network.

In order to support high-speed transmission and better coverage, 5G uses LDPC and large-scale antenna technology with stronger performance. In order to support low latency and high reliability, 5G uses technologies such as short-family bucket frames and multi-layer and multi-site data retransmission.

Operating environment

Brand model: general

System version: General

The three characteristics of 5G are: 1. High speed; 2. Low latency; 3. Wide connection. Fifth-generation mobile technology is the latest generation of cellular mobile communication technology, and the performance goals of 5G are high data rates, reduced latency, energy savings, reduced stove costs, increased system capacity, and large-scale device connectivity.

In June 2018, 3GPP released the first 5G standard (Release-15), which supports 5G standalone networking, focusing on meeting the needs of enhanced mobile broadband services. In June 2020, the RELEASE-16 version of this standard was released, focusing on supporting low-latency and high-reliability services, and realizing support for applications such as 5G Internet of Vehicles and industrial Internet.

Development Background. Mobile communication continues the development of a generation of technologies every decade, and has gone through the development of 1G, 2G, 3G, and 4G. Every generational leap and every technological progress has greatly promoted industrial upgrading and economic and social development.

From 1G to 2G, the transition from analog communication to digital communication has been realized, and mobile communication has entered thousands of households.

From 2G to 3G and 4G, the transformation from voice services to data services has been realized, and the transmission rate has increased by hundreds of times, promoting the popularization and prosperity of mobile Internet applications. At present, mobile networks have been integrated into all aspects of social life, profoundly changing people's communication, communication and even the entire way of life.

With the rapid development of the mobile Internet, new services and new services continue to emerge, and the flow of mobile data services is growing, the 4G mobile communication system is difficult to meet the soaring demand of mobile data traffic in the future, and it is urgent to develop the next generation of mobile communication (5G) system.

The contents of the three major technologies of 5G are as follows:

1. Ultra-dense heterogeneous network. Ultra-dense heterogeneous network technology is an inevitable product of the development of mobile communication to the convergence stage. With the continuous enrichment of mobile communication application scenarios in the future, the requirements for network information transmission will show non-uniform characteristics with time and place.

In the past, the mobile communication network architecture based on macro cells and for the purpose of regional coverage has been difficult to meet the exponentially growing segmentation needs.

2. Self-organizing networks. The purpose of self-planning is to dynamically plan and execute the network while meeting the needs of the system for capacity expansion, service monitoring, or optimization results. The configuration of self-provisioning is the configuration of new network nodes that can be plug-and-play, which has the advantages of low cost and easy installation.

The purpose of self-optimization is to reduce the workload and improve the quality and performance of the network.

3. Content distribution network. A content delivery network is a new layer to a traditional network, an intelligent virtual network. Using the method of big data analysis, the CDN system comprehensively considers the connection status, load situation, user distance and other information of each node, and distributes the relevant content to the CDN server close to the user, so that the user can obtain the required information nearby.
