2021 is a year for 5g to accelerate its popularization. While rapidly deploying 5g basic network coverage, 5g technology is also making rapid progress, especially the faster 5g millimeter wave technology, which will promote 5g to release its potential in high-performance application scenarios such as high-definition video, AR / VR, industrial Internet, Internet of vehicles, etc.

It is predicted that China will issue 5g millimeter wave license in 2022. It can be predicted that in the next few years, 5g millimeter wave will be an important direction to play and improve 5g network and 5g application.

China's 5g millimeter wave technology has entered the commercial sprint stage

5g millimeter wave application scenarios accelerate landing

In the 2021 MWC world mobile conference held in Shanghai, 5g millimeter wave has become one of the hot spots of many eyes.

At the conference, the 5g millimeter wave exhibition area, sponsored by China Unicom and GSMA and supported by Qualcomm technologies, made a wonderful appearance, fully showing the audience the extreme performance and rich applications of 5g millimeter wave power in all walks of life.

It is understood that in the 2022 Beijing Zhangjiakou Winter Olympic Games, millimeter wave technology has been clearly deployed to enhance the experience of watching the games, which can realize multi angle live broadcast of the games.

According to the staff of China Unicom, although the coverage area of 5g network signal in millimeter wave band is relatively small, its bandwidth is larger, which can realize higher transmission speed and lower delay network, and can meet the demand of high-definition live broadcast of events. On the other hand, the capacity of 5g millimeter wave is higher, which can not only meet the Internet demand of more people, but also more easily solve the network congestion problem when many users use high frequency network at the same time. Therefore, it is more suitable for indoor scenes such as sports venues with dense population.

In the 5g multi view live game show, through the millimeter wave 5g multi view live game program of China Unicom, media reporters can directly view the outfield of Zhangjiakou international cross-country skiing center, and connect UAV, head mounted camera and professional camera with base station communication through wireless network to realize multi view live game, so as to provide diversified experience for spectators.

It can be seen that the application of 5g millimeter wave will fully release 5g potential. Compared with 4G, 5g can use more spectrum resources to meet different kinds of business needs. The biggest characteristic of millimeter wave technology is that the network bandwidth is large and the network speed is fast. Millimeter wave band has a large number of continuously available spectrum resources.

Under the field speed measurement in the Qualcomm exhibition area and the 4 * 200m bandwidth carrier aggregation, the network speed has reached 4.4gbps, far exceeding the 5g network currently widely used.

At present, 5g in China is mainly sub-6ghz and 6GHz. With the improvement of 5g permeability and the rapid expansion of 5g application, the demand for 5g has begun to expand to deeper and more subdivided fields.

The commercial application of 5g network has gradually shifted from low frequency to the mode of low frequency and millimeter wave, so as to achieve the optimal user experience of 5g. Therefore, 5g millimeter wave is bound to become a new direction of 5g development.

5g millimeter wave industry chain is mature

5g millimeter wave industry chain has been basically mature. Huawei, ZTE, Ericsson, CITIC, Nokia bell and other mainstream mobile communication equipment providers have launched base station equipment supporting 5g millimeter wave, and chip and terminal equipment manufacturers have also released a large number of products supporting 5g millimeter wave.

In the 5g millimeter wave exhibition area, a number of manufacturers displayed 5g millimeter wave terminal coverage modules, mobile phones, CPE, PC, AR (augmented reality) and XR (extended reality) devices, live backpacks, robots and other rich categories. Among them, oppo’s 5g millimeter wave CPE shows the charm of high-speed wireless network; vivo brings 5g + 8K ultra high definition video live dynamic display, which fully shows its own 5g millimeter wave R & D technical strength.

In terms of chips, Qualcomm, Hisilicon, Samsung and MediaTek have all deployed millimeter wave chips.

In addition, according to Meng Pu, chairman of China of Qualcomm, at this MWC conference, more than 130 operators around the world are actively investing in millimeter wave technology.

GSMA mentioned in the white paper on 5g millimeter wave technology that the development ecology of 5g millimeter wave industry at home and abroad has been relatively complete, and it has the conditions for deployment and commercialization. At present, the mainstream mobile communication equipment providers have launched 5g millimeter wave base station equipment, and some of them have begun to sell the second or third generation products. Chip manufacturers and terminal equipment manufacturers have also released some 5g millimeter wave products.

In fact, China’s 5g millimeter wave business has long been on the agenda. At the end of August 2020, China Unicom announced its 5g millimeter wave development schedule. According to the plan, the test and scheme evaluation will be completed in March this year, and the millimeter wave end network interoperability test will be completed. In June, we completed the deployment of related sports facilities and the experience deployment of millimeter wave application products. It is generally believed that China will realize 5g millimeter wave commercial use in 2022.

Although 5g millimeter wave is still in the test stage in China, millimeter wave has already been commercialized in other countries and regions in the world. It is reported that the United States, Japan, Southeast Asia and other countries and regions have deployed 5g millimeter wave networks and services. Germany, the United Kingdom, Italy and other European countries, as well as South Korea and Australia will launch millimeter wave commercial deployment this year.

GSMA predicts that 5g millimeter wave, as one of the core enabling technologies in high-speed access, industrial automation, health care, intelligent transportation and virtual reality, will contribute 565 billion US dollars to global GDP by 2035, accounting for one fourth of the total contribution of 5g; by 2034, the economic benefits of using 5g millimeter wave in China will reach about 104 billion US dollars.

In 2021, with the joint efforts of the industrial chain, 5g millimeter wave commercial applications will accelerate the landing, and further promote the development of 5g technology in the direction of higher speed, lower delay and wider application, so that more consumers can feel the new experience brought by 5g. The development of 5g millimeter wave is worth looking forward to.
