Huawei launched new 5G products at MWC 2021, features multi-antenna technology

Published

On June 28, at Mobile World Congress (MWC 2021) in Barcelona, Huawei launched a number of new 5G products and solutions-oriented to the “1+N” 5G target network. These newly launched 5G devices promote multi-antenna technologies to all bands and all scenarios to build a leading 5G network.

Let’s check the new launches one by one:

400 MHz Ultra-Wideband 64T64R Massive MIMO:

This new product supports the entire C-band, enabling operators to deploy their multi-segment spectrum on just one module to reduce the number of devices. It’s the industry’s only massive MIMO product that supports both 64T64R and 400 MHz bandwidth.

Furthermore, this product balances huge bandwidth and high capacity so that one module can be shared by multiple operators. This allows them to overcome the insufficient spectrum that may occur in single-operator cases and greatly improves user experience, while also considerably reducing the footprint and site power consumption of antenna modules compared with separate deployments.

64T64R Massive MIMO:

Huawei’s 64T64R Massive MIMO product is the lightest of its kind, with a single module weighing as little as 19 kg. By continuously innovating in Massive MIMO engineering, Huawei’s new 64T products can be transported and installed with just one person while also delivering on performance, significantly improving construction efficiency.

BladeAAU Pro:

BladeAAU has made it easier for operators in Switzerland to acquire new sites and rapidly deploy 5G networks. By supporting a higher mounting height, BladeAAU has helped operators in China expand coverage and improve the 5G user experience.

Huawei BladeAAU Pro is the only of its kind that is 65T capable while maintaining a high level of A+P integration. The active module is improved with 64 channels over the previous 32 and supports a 320 W transmit power and 200 MHz bandwidth, which provide extra flexibility for operators to meet higher capacity.

The passive module is also improved with port specifications further upgraded to 2L6H to facilitate full sub-3GHz coverage.

BladeRRU Pro:

Huawei’s BladeRRU Pro is the first to integrate three low bands/three medium bands, reducing the required number of FDD RRUs for full-band coverage by two-thirds and making investments in multi-band deployment more efficient.

The low-frequency integration module has been adopted commercially in multiple countries. Huawei provides a SingleCell software solution for BladeRRU Pro to coordinate scheduling between low and medium bands, enabling more resources to serve low-band UEs at cell edges. Commercial use of the solution at multiple sites showed that SingleCell can nearly double the average seen in experience indicators for these UEs.

Industry’s Only Commercial FDD Massive MIMO:

Huawei has launched the industry’s first commercial FDD Massive MIMO products by combining innovative Meta-material array design and ultra-miniature passive intermodulation (PIM)-free filter technology.

The FDD Massive MIMO device is less than 500 mm in width but carries engineering specifications comparable to those of TDD Massive MIMO. Its cell capacity is five to six times higher than 4T4R while providing similar in-depth coverage performance as that of sub-1 GHz bands.

“By launching this series, we aim to bring multi-antenna technology to all scenarios and bands. Several products within the solutions are one-of-a-kind and will help operators efficiently deploy 5G networks and provide a first-rate experience. Huawei will work with global partners to innovate and share 5G benefits with all.” said Yang Chaobin, President of Huawei Wireless Product Line.

Most of Deng Li's smartphones are from the Huawei ecosystem and his first Huawei phone was Ascend Mate 2 (4G). As a tech enthusiast, he keeps exploring new technologies and inspects them closely. Apart from the technology world, he takes care of his garden.

Huawei will continuously solve survival problems: Chairman

Published

Huawei

On September 26, Huawei attended the opening ceremony of STW 2022. At this event, the new rotating chairman of the company – Xu Zhijun delivered a short speech. He described how Huawei needs to make efforts in the field of research and development to solve environmental and survival problems.

Xu Zhijun reports that for confronting the survival problems in an extreme environment and developing a fruitful future, Huawei must continue its research and open innovation. Although, the company is trying its level best to prepare itself for future challenges. Yet, it is necessary to concentrate well on the technical field.

Over the last decade, Huawei has funded more than 845 billion yuan [118 trillion USD] in research and development. Besides, it marked an expenditure of more than 20 billion yuan [2.81 billion USD] in basic research.

However, the Chinese manufacturer managed to establish 86 basic tech labs and 172 joint laboratories for innovation. But, it’s time to focus on the new emerging obstacles that could harm the growth and evolution of the company, if not prevented.

Some major challenges:

Xu believes that even after a lot of achievements, several hurdles are waiting ahead in this evolution journey:

  • Firstly the carbon neutrality goal. Challenges like poor stability in energy generation, low conversion efficiency, high energy storage price, less security, and mismanagement are standing in the mid-way.
  • Global computing power demand is facing 2-3 orders of magnitude in the next coming years. Supply Chain and other essential components require more enhancement.
  • Users are expecting the 5.5G network to exhibit an increase of 5 times in the uplink and downlink rates. What kind of core technology will the 6G network need is still a big question for the company.
  • Artificial Intelligence is still a topic of concern for many operators. Its security, interpretability, small samples, computing data, and more are not easy to handle.

And the list continues to a far distance. Though the company has come up with several things, there is still a lot to move on with. Xu says,

“We need to work together to fully release the productivity of all walks of life, give birth to new industries, new business forms, and new models, and promote the progress of the world.”

Huawei 100W fast charging power

Today, Huawei and some other tech manufacturers have gained fast charging certificates with a certified power of 100W. Apart from the smartphone devices, the certificates have approached some other charging equipment as well.

So far, we only heard that the general charging power of the new technology at the moment is 40W and it will gradually come to the count of 65W. However, the fast-charging certified power for Huawei and other partners is dynamically 100W.

Aside from smartphones, a few fast-charging chips, and charging products have also obtained these certificates. This is a good sign and indicates that soon consumers will experience an advanced way of powering up their devices.

Fast Charging: New Addition to the Technology field

Fast Charging is a new topic in the world of technology. Recently, the China Communications Standard Association and Telecom Terminal Industry jointly conducted a huge fast charging achievement conference in Beijing.

At this event, the cooperation released the first batch of fast charging certificates for 11 high-end products. These products consist of 4 terminals, 5 adapters, and 2 chipsets from 6 companies including Huawei, Oppo, Vivo, and Xiaomi.

As a major part of this event, all four tech giants also delivered a short speech on how this unified fast charging will bring a safer and more secure environment for consumers. Thereafter, the cooperations began the certificate distribution procedure.

New Charging Technology will take time to adapt!

The Chairman of the Telecommunications Terminal Industry Association – Shi Xiaoguang mentioned that the sudden change in the traditional charging technology can give rise to several problems. For instance interoperability issues in interfaces, protocols, cables, and more.

Consequently, these issues will not only harm the user experience but will also risk security. Hence, to maintain the charging ecosystem, the Telecom Association will continue to integrate with China Communications firm to promote and expand the fast charging technology in the field of technical application.
