The 5G appearance time point has been set, the global standard is expected to be unified

In today's communications industry, the time to enter 5G has been locked in 2020. 5G is not only the evolution of mobile broadband, but also revolutionizes the entire communications industry, and changes the work and lifestyle of each of us, so that human society can fully enter the digital age.

Different 5G era

5G is not only the next generation mobile communication standard, but also the basic architecture of the future digital world. In the 5G era, the single-user rate is expected to reach 10Gbps, the number of connections will reach 100 billion, and the minimum latency will reach 1 millisecond. At the 2014 Global Mobile Broadband Forum (Global MBB Forum2014) held in Shanghai recently, Huawei and various telecom operators, regulatory agencies and universities around the world shared 5G research results, technology trends and development strategies.

Mobile connectivity breaks through the limitations of time and space, making everyone's life and work styles change. Traditional industries also generate new modes of operation. Mobile office, mobile shopping, mobile payment, etc. have penetrated into everyone's work and life. . Mobile Internet of Everything is already the consensus of the whole industry, and it will definitely be the next development trend of mobile broadband.

Yang Chaobin, chief marketing officer of Huawei's wireless network product line, admitted that there are many different opinions about 5G in the industry, but it does not form a unified norm or unified recommendations and unified standards. Therefore, at this year's Global Mobile Broadband Forum, Invited more than 300 operators worldwide and more than 100 potential future 5G application customers, such as the automotive industry, including some partners in other industries of the Internet of Things, through cross-border discussions to discuss what the future of 5G should be Look like?

"5G is not just an upgrade of the entire mobile network. It will be the driver of the entire digital society in the future. The application of 5G will be expanded from the communication of people to the communication of people, things, processes and content. 5G will It will change our way of life, work and entertainment. The more popular applications mentioned in the industry include auto-driving, remote surgery, telemedicine monitoring, etc. In addition, 5G technology will be widely used in agriculture, water conservancy, Manufacturing industry, industry and other fields, so we believe that 5G is the driver of the entire digital society in the future." Yang Chaobin pointed out in the depiction of 5G.

The world is expected to unify the 5G standard

The frequency of 5G is one of the factors that have not yet been determined. Yang Chaobin said that from the number of Huawei mobile base stations in the world in the past three years, the global mobile network is growing at a rate of 60% every year. This also means that mobile communication networks require more frequency resources. Considering the wider application range of 5G and greater capacity and bandwidth, and as the primary channel for digital content distribution such as video, Huawei hopes that future regulatory agencies will be able to allocate more spectrum resources to 5G.

Technically, Huawei believes that the frequency band below 6 GHz is still the main frequency band of 5G. Yang Chaobin said: "With frequency bands below 6G, operators can complete better coverage with fewer stations, which will help improve social and economic benefits and benefit end consumers. In some areas with particularly dense capacity. Some high-end spectrum should be allocated as a supplement to the core spectrum below 6 GHz. Where dense and large-capacity coverage is required, densely connected hotspots can be covered with high-end spectrum around 40 GHz. 5G should also have the available frequencies for convergence. ability."

Technical standards are prerequisites for the deployment of all mobile communication technologies. Currently, the 5G standardization process has not yet started. After reviewing the development history of mobile communication standards, Yang Chaobin said that 5G must achieve the unification of global technical standards.

"The development of mobile communication from 1G to 4G has gradually formed the LTE unified standard, which is of great significance to the development of the global mobile communication industry. It not only solves the global roaming problem of consumers, but also expands the scale of the industry and greatly reduces the terminal cost. In the 5G era, the meaning of global unified standards is even more important, because 5G also needs to carry the connection of things and things, involving the application of different industries in the society. If you make a separate standard for each industry, you cannot form an industrial scale, equipment and Terminal costs are difficult to reduce." Yang Chaobin said.

The 5G global standard includes two aspects: on the one hand, the adoption of uniform standards in different regions of different countries, and on the other hand, the application of 5G will be applied to various industries in the whole society. Huawei hopes that all industries in the world can adopt a unified 5G standard, which will benefit the expansion of the industry and benefit the whole society. To this end, Huawei will strive to become a core technology innovator in the 5G standardization process.

When talking about the timetable for Huawei's 5G development, Yang Chaobin made it clear that Huawei will deploy the 5G experimental network in 2018 and formally commercialize it in 2020.

We can explain several features of the future 5G network from three latitudes.

First, the 5G network connection will reach 100 billion, which means that the number of users that each station can connect at the same time may be very large. It may be enough for each station to have dozens, 20 or even 100 users. However, in the connection of high-density areas, the number of connections per station may reach 1 million, which poses challenges for 5G network design.

Second, with the continuous improvement of communication demands, everyone can enjoy hundreds of K services in 2G, 3G can reach dozens of megabytes, and can enjoy hundreds of megabytes of service when 4G, we hope to be able to Providing a peak rate of 10G, so that everyone can watch video, can play some virtual reality games, and can make some personal data services on the cloud possible. From here, the peak rate of 5G must reach 10Gbps.

Third, the appeal of delay. In these application scenarios, car autopilot is undoubtedly very attractive. Network delay is a very important factor in achieving auto-driving. If the speed of a car reaches 120 kilometers per hour, then the distance that can be moved in 1 millisecond is almost 3 centimeters. In general, in a 3G network, the delay is about 100 milliseconds, the delay of the 4G network is 20 to 30 milliseconds, and the delay of the 5G network can be shortened to 1 millisecond, which is enough to support the auto-driving function of the car.

Yang Chaobin pointed out: "From the perspective of future applications, 5G networks must have the characteristics of these three aspects. The current 2G, 3G, 4G networks can only meet part of the above business requirements, which is why Huawei believes that 5G is the future society. Drivers, not just 4G network upgrades."
