[Asia Economy Reporter Minyoung Cha] Huawei announced on the 3rd that it introduced its new product, the ‘Intelligent RAN (Radio Access Network) Architecture,’ at the Mobile World Congress (MWC) 2022 held in Barcelona, Spain. It also highlighted the latest wireless solutions, including the 3rd generation TDD (Time Division Duplex) Massive MIMO (Massive Multiple Input Multiple Output) products and the Frequency Division Duplex (FDD) ultra-wideband multi-antenna products.

Gan Bin, Vice President of Huawei’s Wireless Network Product Division, said in the keynote speech titled ‘Innovation for a 5G Gigabit Society,’ “While 5G broadband and multi-antenna technologies have brought clear advantages, we are not stopping here and continue to innovate in both areas.” He explained, “Huawei’s 3rd generation Massive MIMO and FDD ultra-wideband multi-antenna portfolio further enhances network performance and energy efficiency, supporting carriers in building high-quality, eco-friendly 5G networks.”

3rd Generation TDD Massive MIMO Series

Huawei’s newly announced 3rd generation TDD Massive MIMO series includes the ‘3rd Generation Meta AAU’ and the ‘Blade AAU Series.’ It is the only one in the industry to double the number of antenna elements from 192 to 384 compared to the previous generation.

The 3rd Generation Meta AAU uses an Extremely Large Antenna Array (ELAA) and Adaptive High Resolution (AHR) turbo beamforming algorithms to improve the performance and energy efficiency of massive MIMO. Internal tests showed that compared to the existing 64T, this product’s coverage improved by 3dB and user experience by 30%. Compared to 32T, coverage improved by 6dB and user experience by 60%.

Based on the same coverage, power consumption is reduced by about 30% compared to existing AAUs. For cases using non-contiguous frequencies or requiring network co-building and sharing, the ultra-wideband product with 400 MHz bandwidth and 400W transmission power facilitates simpler implementation. In situations with limited antenna space, Huawei’s Blade AAU series supports deployment in frequency bands below 6 GHz and operation in all scenarios.

FDD Ultra-Wideband Multi-Antenna Product Line

New solutions in the FDD ultra-wideband multi-antenna product line include the ‘4T4R RRU,’ ‘8T8R,’ ‘EasyMacro 3.0,’ and ‘Book RRU 3.0.’ The 4T4R RRU, which supports the lightest broadband, enables multi-band network deployment at 700?900 MHz, 1.8?2.6 GHz, and 1.4 GHz, allowing dynamic power sharing in all modes. This improves user experience by 30% while reducing power consumption by 30%.

The industry’s first high-power ultra-wideband 8T8R uses a combination of 1.8 GHz and 2.1 GHz to provide coverage equivalent to sub-1 GHz bands, increasing capacity by 1.6 times for 4G and 3 times for 5G networks. The only 8T8R native product equipped with the Hertz platform’s eco-friendly antenna reduces energy consumption by an additional 15%. For high-capacity needs, Huawei also offers the industry’s only commercial FDD massive MIMO that can increase 4G network capacity by 3 times and 5G network capacity by 5 times compared to 4T networks.

Additionally, Huawei announced the launch of the dual-band TDD and FDD ‘EasyMacro 3.0’ and ‘Book RRU 3.0 solutions’ to simplify on-demand deployment in residential areas and major urban centers and quickly fill vacant 5G coverage. Huawei is the only company in the industry to provide distributed massive MIMO that meets indoor space requirements such as train stations and shopping malls, offering 4 times the capacity of 4T and more than 30% improvement in user experience, delivering gigabit experiences anytime and anywhere.

Intelligent RAN Launch

Huawei’s newly launched ‘Intelligent RAN’ is an architecture that operates intelligently across all aspects of wireless networks, including user experience, eco-friendliness, services, and operations and maintenance (O&M). It achieves network autonomy through data, models, and decision-making collaboration between site and network layers using the Mobile Intelligent Engine (MIE). The four characteristics provided by Huawei’s Intelligent RAN architecture are ▲Smart Experience ▲Smart Green ▲Smart Service ▲Smart O&M.

Vice President Gan said, “Huawei’s Intelligent RAN realizes an automated, contactless network with zero latency, enabling autonomous networks characterized by smart services, optimization, eco-friendliness, and simplified maintenance.” He added, “Huawei will continue to do its best to support carriers in exploring new spaces and business opportunities for 5G.”
