As one of the three thinkers in the digital age, George Gilder pointed out in 1993 that the bandwidth of the backbone network will double every six months in the next 25 years, and its growth rate is three times that of the CPU growth rate predicted by Moore's Law.
This is the famous Gilder's Law (Gilder's Law) , which has been fully confirmed for generation after generation of network evolution. In fact, what promotes network capabilities is not the law itself, nor technology and solution providers, but the most real needs from clients.
With the continuous development of industry digitalization and the gradual deepening of the application of technologies such as VR and AR, the demand for network capabilities has risen to a new level. Downlink 10Gbps and uplink 1Gbps have become a consensus...higher requirements are placed on existing networks.
At Huawei's 20th Global Analyst Conference on April 19, Meng Wanzhou, Huawei's vice chairman, rotating chairman, and CFO, clearly stated, "We will continue to promote the construction of leading digital infrastructure in the 5.5G era and build hundreds of billions of things. The network capability of network connection and 10 Gigabit experience."
5.5G will inevitably become a key step in the evolution of 5G! The evolution from 5G to 5.5G is not only related to the digitization of thousands of industries, but also to each of us.
Build a better intelligent world
As early as November 2020, Huawei first proposed its 5.5G vision at the 11th Mobile Broadband Forum (MBBF). At that time, Huawei called on industry partners to jointly define 5.5G and build a beautiful and intelligent world.
In the following two years, more and more industry partners, as well as global authoritative communication technology organizations including 3GPP, jointly promoted 5.5G, and its standardization work was officially launched and progressed rapidly.
The upgrade and evolution from 5G to 5.5G has become a deterministic industry development trend recognized by the industry. The verification of 5.5G (5G-Advanced) technical standards in various application scenarios means that the tenfold increase in network capabilities will trigger the release of stronger digital productivity in all industries and accelerate the arrival of 5.5G commercial applications .
At this Huawei Global Analyst Conference, Gan Bin, vice president of Huawei's wireless network product line and chief marketing officer, gave a keynote speech on "bringing 5.5G into reality". He believes that with the accelerated maturity of the 5.5G industry chain and the gradual clarity of business scenarios, the accelerated integration of manufacturers and manufacturers will bring 5.5G into reality, which will surely bring new development opportunities to the entire industry.
With the joint efforts of the industry, substantial breakthroughs have been made in several key technologies of 5.5G: innovative technologies such as ultra-large-scale antenna array (ELAA) for wireless networks and virtual large-carrier reconstruction discontinuous spectrum (MBSC) have been used globally. Multiple operators have completed the verification, bringing the 5.5G 10G capability into reality.
We have seen that 5.5G, which has been continuously enhanced in terms of ultra-broadband, intelligence, security, and delay, has brought new capabilities, new products, and new opportunities to many leading operators in the world, and has continuously accelerated the growth of operators' performance. .
Everything is ready, 5.5G is coming soon
There is no doubt that 5G has become the fastest-growing new-generation mobile communication technology in history, but to undertake the important task of enabling the digital transformation of thousands of industries, 5G needs continuous innovation and continuous evolution.
"If a worker wants to do a good job, he must first sharpen his tools." In the face of the roaring intelligent age, all kinds of beautiful blueprints that people imagine in the industrial chain and business scenarios must be built on more powerful network capabilities.
Based on this, the 10 Gigabit capability has become a reality first, and this is one of the important directions of 5.5G. Gan Bin said that 5.5G will bring new breakthroughs and progress to mobile networks, bringing more possibilities for future smart life and digital economy. :
Ready for 10 Gigabit business scenarios: Firstly, the experience of the People’s Association is being upgraded, and consumer mobile services are becoming immersive and interactive; the experience of the Family Association business is also undergoing upgrades, and the large screen of the family is moving towards 3D high-definition...
Obviously, such innovative services and experience changes as above are based on network upgrades. From Experience 1.0 marked by "Ubiquitous Gigabit" to Experience 2.0 marked by 5.5G "10 Gigabit Downlink + Gigabit Uplink + Deterministic Experience" is the only way for future commercial and personal applications and enterprise digitization.
10G ultra-large bandwidth spectrum and chip Ready: For the much-anticipated 10G experience, spectrum and chips are indispensable cornerstones. For example, as the key spectrum for 5.5G, millimeter wave has been allocated in 25 countries, and has the resource guarantee to realize the 10Gbps capability. At the same time, the 5.5G chip supporting 10Gbps has also been officially released.
"The cornerstone of 10 Gigabit experience has been built." Gan Bin said.
10 Gigabit product Ready, ELAA-MM (Extremely Large-Scale Antenna Array M-MIMO) is moving towards the full frequency band: For Sub6GHz TDD spectrum, ELAA-MM is a must for 10 Gigabit continuous coverage, and the 4.9GHz coverage capability is aligned with the 2.6GHz and 6GHz coverage capabilities Aligned to 3.5GHz. For millimeter wave spectrum, ELAA-MM enables millimeter wave to break through the mobility and coverage problems and realize ubiquitous high-speed mobility experience; for Sub3GHz FDD spectrum, ELAA-MM+MBSC enables a more deterministic experience.
Accelerate the 100 billion Internet of Things in an all-round way
People are excited about the changes brought about by 5G, but this is just the beginning. 5.5G, which is ten times the current network capacity, will truly realize 10 Gigabit experience, 100 billion connections and endogenous intelligence in the process of human society moving towards a smart world, and meet rich and diverse innovative business needs.
Gan Bin pointed out that 5.5G has made the acceleration of hundreds of billions of things a reality. The 100-billion IoT industry is being upgraded, from the high-speed and high-value connection (5G NR) of IoT 1.0 to the full-scenario application of IoT 2.0, and the extensive connection of all scenarios, processes, and elements in all walks of life.
As a 5G lightweight technical standard in the 3GPP R17 stage, the industrial chain of RedCap core mold has become increasingly mature. It is reported that by the end of 2023, there will be 50+ commercial terminals on the market. The commercial scale of RedCap is accelerating, and it has begun to be applied in various scenarios such as smart power, smart security, and smart manufacturing.
Passive IoT, which combines cellular networks and passive tag technologies, is also maturing rapidly. Terminal Tag prototypes are ready, and spectrum, product forms, and business models are being defined at an accelerated pace. At that time, Passive IoT will create a full-scenario connection base, which will enable the transparency and visibility of the entire process of factory logistics and production, and can increase production efficiency by 10-30%.
In addition, the integration of communication and perception brought by 5.5G will provide beyond traditional connections and open up new businesses for operators. The sensing capabilities from new frequency millimeter wave to stock spectrum are constantly being explored. At the same time, perception business scenarios are also constantly being explored, from smart transportation to smart oceans, low-altitude synaesthesia and other diverse needs.
