During the 2021QQ Mobile Broadband Forum, Huawei officially unveiled a full range of innovative solutions for the 5Gigaverse. At a time when the Metaverse has become a hotly debated concept, Huawei threw out the 5Gigaverse concept, aiming to build a ubiquitous network by integrating 5G, Giga, and Universe. gigabit experience network.

“The next decade is a decade of continuous innovation in 5G, and if 5G development is to succeed, it should be built in a deep and thick way in the construction of the infrastructure network. To use.

The first results of “road and other cars”: demand drives technology development


The technology evolution of the mobile communication industry, ten years a generation, from the establishment of standards to commercial use, in the context of countries rush 5G, the overall development of 5G has gradually entered a good place, driving QQ mobile Internet booming development.


In the midst of this, as the “vanguard” of 5G construction, two years after licensing, with the joint efforts of all parties in the industry, the scale of 5G base stations in China has exceeded one million, covering all prefecture-level cities, more than 95% of counties and 35% of towns, and achieving full commercialization of 5G independent group network architecture, the number of 5G base stations is expected to exceed 1.4 million by the end of the year, and 5G The number of 5G base stations is expected to exceed 1.4 million by the end of the year, and 5G coverage will be further extended to more areas. From January to August, 168 million 5G cell phones were shipped in the domestic market, up 79.7% year-on-year, accounting for 74.1% of cell phone shipments in the same period, solidly advancing into the “no man’s land”.

At the same time, as 5G continues to penetrate, changes in user behavior and industry digital transformation needs to go deeper are putting higher demands on 5G.


The Tokyo Olympics, which came to an end a few days ago, was a true “Olympics on the cloud” as the Olympics were broadcast for the first time using QQ cloud due to the impact of the epidemic. Broad Access) users grew faster than wired, and 5G DOU also grew 3 times compared to 4G under the development of video service.


Related data points out that future mobile network traffic will rise exponentially, it is expected that in 2030 the cellular network user DOU will exceed 600GB, FWA user growth will reach 10 times the growth rate of wired broadband users, the cellular network will carry more than 50% of the Internet traffic, it can be seen that by 2030, mobile network traffic may exceed wired, become the main bearer of user Internet traffic.


In terms of toB, QQ5GtoB industry exploration has also been fruitful, in China 5GtoB applications have entered more than 20 industries, application AL more than 10,000, project contract amount of more than 40 billion yuan, to port, mining, power, steel, manufacturing, medical and other industry applications have also opened scale replication, 5G business value to further enhance.

However, the success of every generation of mobile technology cannot be achieved overnight, and 5G, which is tasked with enabling the digital transformation of thousands of industries, has a long way to go. As 5G standards continue to evolve, the products and technologies that go with them need to be constantly updated to meet the rigid demands of the digital era.

5Gigaverse “three primary colors”: comprehensive coverage, gigabit experience, green and low-carbon

The basic requirement of 5G design is to meet the demand of network data traffic growth in the next decade, and the advantage of the network depends on the scale and coverage of the network, although China’s 5G network has a certain scale, but there is still a large gap compared to 4G, in the context of high energy consumption and high cost of 5G, how to help operators to deploy high-quality network at low cost has become a major issue.


In my opinion, the launch of 5Gigaverse full series of innovative solutions is an insight into the deployment pain points of operators, around the “comprehensive coverage, gigabit experience, green low-carbon” three aspects through the “macro pole micro” three-dimensional networking mode, to build A 5G network with continuous coverage.


As Yang Chaobin, president of Huawei’s wireless network product line, pointed out, the goal of 5Gigaverse is to build a ubiquitous gigabit experience network, from hotspot coverage to full-scene coverage, from one person’s gigabit to everyone’s gigabit, from the first industry scenario to the whole industry digitalization.


Specifically, the operator’s network construction investment, macro station investment accounted for up to 45%, how to ZD enhance macro station capacity and coverage has become a key proposition. Currently, multi-antenna and ultra-broadband technology has become the choice of most operators in QQ, and for the different characteristics of operators’ FDD spectrum and TDD spectrum, 5Gigaverse makes station value ZD by building a wide pipeline infrastructure network with continuous coverage.


As we all know, TDD spectrum has high bandwidth and large capacity, but the coverage capacity is weaker than low frequency, and needs to improve coverage; FDD spectrum coverage has advantages, but the spectrum is fragmented, and needs to improve capacity. For TDD continuous large bandwidth spectrum, Huawei launched the industry ZD bandwidth 400MHz Massive MIMO products, enabling the minimal deployment of fragmented spectrum scenarios, while in the space-constrained scenario for the sky, Huawei BladeAAU to simplify the integration of Sub-3G and Massive MIMO, to achieve the full frequency active-passive unity below 6GHz, to achieve It achieves the minimalist deployment of 5G Massive MIMO in a single sky plane.


The traditional solution to improve base station coverage is to increase RF transmit power, but this can only improve downlink coverage, but cannot break through the uplink coverage limit, and increasing transmit power also leads to increased module energy consumption, which contradicts the goal of green energy saving.

According to Yang Chaobin, Huawei MetaAAU improves coverage while enhancing integration through the introduction of ELAA ultra-large scale antenna array and AHR Turbo innovative solution, the former uses 384 antenna arrays compared to the traditional AAU 192 arrays, and also improves integration by introducing ultra-light integrated arrays, SDIF and other technologies; the latter relies on adaptive high-resolution beam assignment algorithm to significantly improve user experience and cell capacity. Compared with traditional 64T AAU, the coverage is improved by 3dB, and compared with traditional 32T AAU, the coverage gain is up to 6dB. At the same time, the base station can be configured with lower transmit power while the coverage index remains unchanged, and the energy consumption is reduced by about 30% compared with traditional AAU.


In response to some markets where TDD large-bandwidth spectrum has not yet been released, Huawei’s ultra-broadband 4T, 8T and Massive MIMO innovative solutions enable the evolution of the stock Sub-3GHz spectrum to 5G to meet future network development requirements; and for residential areas, dense commercial areas and some scenic areas with high environmental protection, relying on the characteristics of small size, light weight and strong scene adaptability, Huawei The pole station series can be deployed on demand, and can quickly make up for the blind heat absorption on the basis of the basic coverage of 5G macro base stations.


It is worth noting that in the 5G era, the frequency band continues to go high and the application scenario expands, with more than 70% of the demand expected to come from indoor, which puts new requirements on the indoor coverage capability of operators. In this regard, Huawei provides the LampSite solution, which can meet the scenario-based and differentiated needs of the ToB industry by combining indoor distributed Massive MIMO solutions to realize indoor ubiquitous Gbps experience and cover key indoor scenarios such as airports, railway stations, shopping malls, etc.

Intelligent Engine: Escorting the 5Gigaverse Society


Admittedly, 5G network is a multi-system, multi-technology and multi-format convergence network, i.e. the mutual integration of FDD and TDD, Sub 6G including 700M and millimeter wave, public network and private network, macro coverage and micro coverage, and special indoor and outdoor scenarios represented by tunnels and underpasses, so as to build a 5G coverage network for all scenes.


In the next decade, multi-frequency and multi-standard will coexist, and operators need to consider macro-pole-micro three-dimensional network construction and operation and maintenance, as well as toC/toB/toH differentiated experience guarantee, and also need to balance network performance and power consumption, etc. Therefore, building 5Gigaverse, there are bound to be many challenges, such as the need to introduce intelligence into wireless networks.


In response to these challenges, Huawei released the Intelligence Engine, covering three major solutions, PowerStar2.0, Capacity Turbo and WTTX Suite, to improve the user experience while significantly reducing the overall energy consumption of the network, driving the network continuously towards autopilot.


Among them, PowerStar2.0 introduces intelligence to base stations and realizes intelligent energy-saving strategies based on factors such as coverage, load and service type through AI. Based on multi-dimensional collaboration, it realizes key capabilities such as full-area energy saving and second-based seeking to guarantee KPI performance; Capacity Turbo solution is to realize macro-pole micro three-dimensional collaboration and full-band full-scene experience ZY through intelligent analysis and decision making such as beam measurement, call map and user rate; 5G WTTx Suite is based on user location for accurate rate evaluation and network change-based user Experience guarantee, enabling extremely fast FWA service issuance and user-level experience guarantee.

The next decade is the decade of 5G, a predictable digital world is accelerating. In my opinion, any YX product or solution from the launch to become a hit, and HX advantage is no different from the accurate satisfaction of the industry to reduce costs and increase efficiency HX demand, and behind this, the same can not be separated from their own around the industry pain points of continuous attack, continuous innovation.


“Innovation is an eternal topic.” As Yang Chaobin pointed out, 5G will continue to evolve and accelerate innovation, but 5G is not only the operator’s 5G, but also the 5G of thousands of industries. The only way to continuously meet user needs and improve usage scenarios and lead the whole industry to digitalization is to work together with the QQ industry chain and continue to innovate around user experience and industry needs.
