Information

According to the economic analysis of 5g millimeter wave released by GSMA in 2021, through the comprehensive analysis of the development cost, gain and economic benefits of 5g millimeter wave, it shows that the combination of 5g millimeter wave and if C-band will bring obvious cost optimization and gain to operators in the scenario of high-density urban deployment and fixed wireless access.

According to bi Qi, chief expert of China Telecom, director of the expert committee of the Telecommunications Research Institute and academician of Bell Laboratories, up to now, there are more than 4500 5g vertical industry applications in China, more than 50% of which are applied in industry, 20% in government services, 10% in transportation and 10% in medical industry, and the rest are applied in education, finance and other fields respectively.

"Now, in order to do a good job in the application of the vertical industry, we must pay attention to two challenges: one is how to solve the fragmentation of the vertical industry and make the wireless communication industry chain develop rapidly in the vertical industry; the other is how to better reduce the price of 5g terminals and modules." Beech said that in the future, China Telecom and China Unicom will continue to deploy 5g millimeter wave networks based on 3.5GHz TDD and 2.0GHz FDD networks to meet the needs of various industries.

Ma Hongbing, general manager of science and technology innovation Department of China Unicom, put forward the view that millimeter wave will help operators "have more legs and more ways" in networking. He said that millimeter wave has greater advantages in accurate positioning than other bands, and can achieve centimeter level or even higher precision positioning, which makes the prospect of millimeter wave in VR and other applications widely promising.

However, he also reminded the industry that 5g is a combined technology. Although it has the characteristics of large bandwidth, low delay, high speed and high reliability, it still needs the sinking of edge cloud or UPF to meet the network demand. This means that 5g is not only facing the improvement of base station and bandwidth, but also needs to adjust and cooperate in the network architecture in order to truly support thousands of lines and industries.

At the same time, the launch of the "sailing" action plan of the Ministry of industry and information technology also shows that 5g and industry applications are now moving from the "ice breaking" stage to "deep blue", which is very difficult. Operators' own understanding of the industry is not deep enough. 5g network and vertical industries must form a close consortium before they can continue to move towards deep water.

Of course, like bich, Ma Hongbing also pointed out that it is particularly important to reduce the cost of millimeter wave as soon as possible in order to carry out large-scale promotion.

Ding Haiyu, director of wireless and terminal Technology Research Institute of China Mobile Research Institute, said that China Mobile has built 700000 5g base stations, and has launched an industry-specific network product system of "preferential, exclusive and exclusive" for 18 key industries such as mines, ports, medical treatment and factories since 2020. However, in his opinion, the network performance is not mature enough, the cost is not low enough, the network industry collaboration is not deep enough, and the end-to-end standardization is not fast enough, which are the four most urgent challenges for the application of 5g industry. Millimeter wave has excellent performance improvement in terms of high reliability, high performance and low delay, which can accelerate the high-quality development of the industry.

"When 5g is applied to the automotive industry, we need to pay attention to three major issues: cost, technology maturity and the scale deployment of 5g network. Whether operators can provide a stable, efficient and safe 5g network determines the degree of deep integration between the automotive industry and 5g." Zhang Zhiqiang, senior manager of BAIC Foton automotive IT infrastructure department / information security department, shared his views in combination with the characteristics of the automotive industry.

Lu Qingjun, representative of the medical industry, director of the office of the national telemedicine and Internet Medical Center and director of the Development Office of China Japan Friendship Hospital, pointed out that the demand of "5g + medical" for the network emphasizes certainty and security on the basis of high throughput and low delay, It can also be said that it is a diversified demand for 5g comprehensive attributes (certainty, mobility, security, real-time, rapidity, specificity), etc. It also includes the urgent demand for MEC and AI capabilities. MEC plays an irreplaceable role in supporting medical AI. However, at present, the maturity of AI system is insufficient, and mec resources have not sunk into medical institutions. There is still a long way to go for clinical application.

"Medical treatment is one of the most complex industries. We had in-depth discussions with China Mobile and China Telecom on how to establish a special medical network and made a lot of plans, but none of them satisfied us." Lu Qingjun said that they have made a rough statistics. Considering multiple factors such as safety, performance and cost, at present, no more than 800 of the more than 230000 hospitals above the second level have opened 5g, accounting for less than one third. Even if it is opened for use, it is only some local small scene applications. Under the background that both doctors and patients are not opened, it is difficult to see some rigid and irreplaceable needs.

"Many hospitals in grass-roots and remote areas don't even know what 5g is, and many doctors don't have 5g mobile phones, which brings great inconvenience to work coordination." He stressed that the medical profession is characterized by "no mistake". Compared with the "advanced nature" of technology, hospitals prefer the "mature" network system. Therefore, in the recently concluded medical special research, through the joint efforts with operators, telecom equipment manufacturers and scientific research institutions, 12 categories of more mature applications such as exhibition, remote diagnosis and mobile ward rounds were included.

However, it is noteworthy that "remote operation" is excluded. Lu Qingjun explained that although several hospitals had achieved a 5g delay of only 5 milliseconds, which was a beautiful figure, it was the result of heavy support at a huge cost, and the cost was not replicable; Secondly, the 256 millisecond delay it really brings comes from the terminal, which is unacceptable to the doctor because he is completely unable to control in this process; Third, the cost is still high, so it is difficult to go deep into the clinical application of grass-roots hospitals.

"What urgently needs to be solved now is the breakthrough of 5g applications from 'one to n', and the core reason for choosing 12 categories of application scenarios is that these applications can be rapidly popularized, and will soon produce large-scale effects in large-scale use in the future," Lu Qingjun said.
