Huawei’s distributed 5G Massive MIMO technology coordinates with indoor cellular network
In 2021, the Chief Marketing Officer of Huawei’s wireless product line – Gan Bin stated that Huawei will continue to lead in 5G Massive MIMO technology. In the latest development, Huawei is offering to emulate 5G Massive MIMO technology, an evolution of its LampSite Digital Indoor Systems.
Currently, the major mobile operators are busy deploying the 5G Massive MIMO technology to their mobile broadband networks. Meanwhile, Huawei’s distributed 5G Massive MIMO solution coordinates indoor radios to act as one logical cell, a design aimed at conferring multiple benefits and to mimic Massive MIMO’s beefed-up antenna arrays.
The radio units in Huawei’s solution feature 4T4R antenna arrays, but by working in combination, a group of radio units can behave as a “virtual” Massive MIMO array. They mimic the Massive MIMO units deployed in outdoor macrocell networks and leverage the throughput-boosting beamforming capabilities that give Massive MIMO its key value.
According to the information, this 5G solution has already been trialed by multiple operators in various scenarios and submitted the measurable results. The multiple benefits of this technique include:
- Interference mitigation. Addressing the above-mentioned challenge inherent in DISs, there’s less risk of cells interfering with one another when they are more tightly coordinated by a central intelligence function. This gives operators more flexibility in deploying radios and helps the network harness the radios’ combined strength.
- Elastic capacity. Huawei’s solution can increase capacity up to four times that of traditional 4T4R DIS systems, helping operators keep up with increasing 5G capacity demands, including the requirements of new revenue-generating enterprise services.
- Uniform support for AR/VR services. Throughout the service footprint (even at the cell edge, where traditional systems would be vulnerable to interference), users can enjoy data rates above 1 Gbps, enough to support augmented and virtual reality and other applications.
- Reliable data rates. The system’s high data rates are dependable and consistent enough that they can be used for critical, demanding use cases such as the transmission of surveillance videos from several cameras (e.g., for quality control, etc.).
- High availability. The network’s redundancy, from baseband to radio units, helps achieve more than 99.99% availability, needed for critical use cases.
Challenges for operators deploying these indoor networks:
- Operators must tailor their service quality to the distinct needs of different use cases. For example, some use cases require high throughput (e.g., for video) while someplace a higher priority on low latency (e.g., remote-controlled vehicles).
- Capacity needs are ever-rising, and increasing network capacity often requires making changes to on-site infrastructure. Those changes (e.g., feeding new cabling through walls or ceilings) can be costly and difficult for operators, depending in part on the individual attitudes and preferences of each venue owner.
- Compared to 4G, 5G poses more risk of interference between the individual cells created by each solution’s radio unit.
To be mentioned, the operators in five countries have already deployed the 5G Distributed Massive MIMO solution system in a total of more than 1,000 sites including:
- In a Chinese factory, China Mobile found the solution achieved an uplink throughput of 1.2Gbps using 160MHz of spectrum. In addition, when China Mobile used the solution to connect industrial cameras over a 1,000-square-meter area, each camera achieved average uplink throughputs of 80Mbps.
- In a convention center in Dubai, another operator, du, reported downlink throughputs of 2Gbps using 200MHz of the spectrum.
- During China’s National Games in September 2021, China Mobile used Distributed Massive MIMO in the Xi’-an Olympic Sports Center, a 63,000-seat venue. The solution served 400 users and reported throughputs of more than 1Gbps downlink, 82Mbps uplink in effectively one cell.
- That same month, at all nine stations of the Guangzhou Metro train, China Unicom saw single-user peak downlink rates of nearly 1.4 Gbps using Distributed Massive MIMO.

Huawei wants to expand its appearance once again in the consumer industry and the company has announced a new plan to grow in the country by opening 100 new stores within 10 days.
Huawei officially announced the launch of over 100 new stores across China and it will start to happen From March 30, 2023, to April 8, 2023. Within 10 days, Huawei will deploy all of these 100+ stores together.
During a special promo opening offer, Huawei will provide attendees with limited-time discounts and gifts. These stores will also bring new products for the consumers at first hand.
These new stores could derive from Huawei Smart Living Pavilion. This is a new step by Huawei to improve its offline retail stores. It has an ingenious design in terms of environment, display, vision, and smart experience.
It also creates a comfortable and modern experience space. Allowing consumers to experience the smart synchronization between all gadgets in multiple scenarios, and truly feel an “immersive + futuristic” Life.
Huawei promised that there will be more exciting activities inside the stores that will allure the customers.
Smartphones:
Recently, Huawei announced new flagship devices – the Huawei P60 series and Mate X3 foldable phones. Packed with new camera technologies, powerful hardware, and eye-catching design, these smartphones bring an all-around experience.
The demand for the P60 and Mate X3 is hot and Huawei doesn’t want to miss the momentum. Therefore, promoting them offline will increase their reach.
Smart Car:
Huawei is now also a car seller, the company is promoting cars with Huawei smart car technologies and helping them to gain new customers via its consumer devices stores. Interested people can go to the store and take a test drive or talk to the related in charge to know more about the vehicle.
Huawei already has many stores in China including experience centers. These provide various on-site solutions for existing devices and also information about the Huawei smart device ecosystem.
Huawei leader Xu Zhijun brought us the good news that his company has achieved a breakthrough in chipset manufacturing and the company will kick off this journey with a 14nm chip node and above.
According to the information, the hardware development tool development team and the supported domestic partner made it possible to achieve a breakthrough at the root of the technology.
The team has introduced new architecture, released a cloud-native schematic diagram tool, created a high-speed and high-sensitive PCB layout too, and improved the 2D/3D CAD tool for structural design.
Huawei has developed a chip design EDA tool team alongside Chinese EDA companies to jointly create EDA tools required to process 14nanometer and above semiconductors.
The rotating chairman confirmed that the basic requirement of localizing these development EDA tools for 14nm and above will complete its comprehensive verification in 2023. In the past three years, Huawei has focused on three R&D production lines hardware development, software development, and chip development.
The Chinese tech maker has worked hard to build our tools and completed the replacement of 78 software/hardware development tools, ensuring the continuity of R&D operations.
Breakthrough:
Huawei said its software development tool is planning the entire operations since 2018. It moved to create a complete software toolchain from coding, compilation, testing, security, construction, and release to deployment and achieve the strategy of self-development.
Also to deliver joint research and development with partners to solve the tool continuity question. Huawei also has the strong support of over 100000 software engineers to provide external services based on Huawei Cloud to achieve internal and external consistency.
As of today, Huawei and its partners have released 11 product development tools and all of the partners are equally eligible to use the production line.
Currently, over 200,000 software developers and 197,000 hardware developers are using the tools developed by us or jointly developed with our partners every month. At the same time, 203 companies are willing to pay to use our software tools.
Xu Zhijun said that Have has made a lot of breakthroughs in product development tools over the years. However, the company still facing many challenges, and there are many product development tools that are yet to make breakthroughs.
This is amazing information coming from the company. Aside from mid-range and budget devices, Huawei can utilize the 14nm chip in network equipment and other products with low processing nodes.
Still, we have to wait for more inputs on this matter and the company’s plans for future manufacturing of the chipset.

Global consumers are excited about the next Huawei smartphones and the company said it will continue to operate in the global market with smartphones and other new products.
Huawei Consumer Business Group COO, He Gang said that Huawei will keep releasing new smartphones, smartwatches, PCs, audio, and other smart products for global consumers.
The latest comment from the COO came during a media interview after the launch of the Huawei P60 series smartphones. He Gang also said that Huawei launched the latest flagship in Spring, which means its products are returning to normal and it’s good news for everyone.
Delayed in the past:
After the U.S. sanctions, Huawei was restricted from purchasing the required hardware technologies to build new smartphones and other devices. The low yield leads to the market share drop.
That’s why Huawei only launched one flagship, P50 Pro in 2021. The phone made it to the global market 6 months after in the first quarter of 2022. On the other hand, the last year’s Huawei Mate 50 Pro made its way to global consumers within 2 months.
These phones were launched without Google Mobile Services (GMS) and Play Store. Therefore, the sales volume in the overseas market remained invisible due to the GMS requirements. Another factor that hit Huawei phones is 5G connectivity. Still, Huawei managed to fill these downsides with new features and powerful camera technologies.
Aside from smartphones, Hauwei is continuously launching new smartwatches and earbuds devices for global customers and it has only increased.
According to the information, Huawei already announced Huawei P60 series will launch on May 9th in Munich and will be accompanied by Huawei Mate X3 and other products.
