Transfer: China Business Network
Report of the press in Beijing
By virtue of ultra-high-speed, time-consuming and sea-based connectivity, 5G, while significantly improving mobile Internet users’ experience, has also enabled the digitization of industry landscapes. The industrial vision for 5.5G was more mentioned as the demand for connectivity increased in vertical industries such as industry, health, logistics.
Various industry sources have indicated to the Chinese Empretec correspondent that 5.5G remains 5G in essence. 5G-Advanced (5G expansion and enhancement, i.e. 5.5G) achieved a 10-fold capacity upgrade compared with 5G, which provided the basis for the maturity of the end-to-end industry by achieving the critical technical requirements of the next-camp rate from the core network, the base station to the end. It can be done faster than 5G to support more frequent, more automated and smart.
Innovative search for 6G
Since becoming commercial in 5G in 2019, as a new generation of communication network technologies, industries have been integrated into various industries to facilitate the digitization of industries. Data from the Department of Safety and Security show that the country has built up the largest and most technologically advanced 5G network worldwide, with a cumulative total of 5G base stations of more than 2.64 million by the end of March this year, 5G networks already cover all the country’s hierarchical, district and town areas, 5G mobile telephone users of 202 million and 5G shared base stations of more than 1.5 million.
According to the White Paper on China’s Development and Economic and Social Impacts (2022), published by the Chinese Institute of Commons, 5G will direct overall economic output of $145 million for the whole of 2022, leading directly to an increase of approximately $392.9 billion, 12 per cent and 31 per cent, respectively, over 2021.
“5G development results for three years equal to four G development years.” As the ICT strategy and President Marketing, P. P. P. P. P. P.son, the first group of operators has been commercially successful in 5G. For many consumers, however, the 5G does not in fact produce subversive applications, apart from being quick.
The Chinese Academy of Engineering, the Director of the Future Mobile Communications Forum, greeted, and despite the remarkable achievements of China in the construction of 5G, there was still a slight deficiency at the application level. 5G, while supporting 4K videos, mobile screens are too small to experience differences in resolution 2K/4K, while other consumption areas are still difficult to feel the advantages of a low-time horizon owing to the premature network of vehicles and XR (extended to expand reality). At the end of the B, 5G costs are still high for medium- and large-scale IoT applications, and the existing capacity of 5G to apply in the industrial Internet area remains inadequate.
Thus, in order to better develop and release the 5G network potential, the concept of 5.5G was proposed to address the problems encountered by the 5G business community, along with an innovative search for 6G.
In response, greetings indicate that 5.5 G to 5G has a quantitative upgrading of performance, which can support the trillions of experience and hundreds of millions of connections. From 5G to 5.5G, the bottom line peak was upgraded from 1Gbps to 10Gbps, with the peak rising from 0.1 Gbps to 1Gbps, with a concentration of connectivity rising from 1 million/m3 to tens of thousands/km3 and a positioning accuracy rising from the sub-minus to the cm level.
In fact, 5.5G is not surprising. The evolution of global mobile communication technology standards has always been an intergenerational cycle of 10 years. As early as the transition from 2G to 3G, GPRS (common wireless cluster operations) has been described as 2.5G between 2G GSM (global mobile communications system) and 3G UMTS (universal mobile communication system). Between 3G and 4G, there is also a less visible 3.75 G. Until 5G was not born, there were also 4.5 G in the industry, as in the case of the former 5G. Indeed, the essence of 5.5G is 5G-Advanced.
In April 2021, 3GPP (Third Generation Mobile Communications Standardization Organization) identified 5G entries as 5G-Advanced and initiated the 5.5G standardization process, 3 GPP standards will adopt technical guidelines for the definition of 5.5G in R18, R19, R20, the first topics for R18 have been set up, and the direction for eMBB (Enhanced Mobile Broadband) has continued to be enhanced, and new 5.5G operations and structures will be further explored in the future R19 and R20, marking the movement of 5.5G from a shared vision.
In August 2021, China’s mobile consortia partners issued a White Paper on the technological evolution of the 5G-Advanced network (1.0), which sets out the developmental philosophy and key technologies of the 5G-Advanced network technology. This is the first industry white paper analysing and elaborating on the evolution of the 5G-Advanced network architecture and technological development.
In December 2021, at the 94th plenary meeting of the 3GPP, 28 topics for the R18 network system architecture were successfully launched, marking the formal beginning of the standardization of 5.5G.
Commercialization in 2025
“5.5G will be commercialized in 2025.”
After nearly two years of joint exploration and efforts by the industry, 5.5G has made key progress, and 5.5G has initiated a standardized process that continues to enrich the technical content of 5.5G and has moved from vision to consensus. Most importantly, its key technologies have also been breakthroughs, with superband bandwidth and large-scale antenna array proven to be capable; in addition, the NB-IoT, supported by 5.5G (a narrow band network), the Red Cap (reducing capacity, understood as “minimum scale 5G”) and the Passive IoT (Non-source Network), have advanced technology and has the capacity to assemble all material.
5.5G-related industrial chains and business landscapes have begun to be prepared. The Chinese Vice-President, Chief Marketing Officer, Gansu, who is the wireless product liner, believes that the rumours of 5.5G will bring new breakthroughs and progress to mobile networks, giving more possibilities for future intellectual life and the digital economy.
Gandhi indicated that, as industry chains and business scenes are ready, the network experience has moved from 1.0, marked by “pan-gugs”, to 5.5G, a “bad giga+” line.
