Xiang Fang, Corporate Vice President and President of Wireless Network Solution of Huawei, unveiling innovation breakthroughs for new communications networks
With booming intelligent devices and services, new devices, traffic, and applications are taking shape in the mobile industry. The new devices are expanding network connectivity from people to things and agents, increasing the number of connections by 100 times. Device-cloud synergy for intelligent services calls for stronger uplink capabilities to support training and inference, shifting network focus from downlink dominance to both uplink and downlink. With new applications, come a diversity of new interaction modes, calling for higher standards in experience and driving networks to support ubiquitous steady ultra-low latency with a high reliability.
As the world steps into an intelligent era, the value of connectivity is not only about quantity—it's more about quality. This has been inspiring Huawei to convert cutting-edge breakthroughs into the commercial practices of new communications networks by focusing on root technologies for ubiquitous experience, simplified and green networks, and superior spectral efficiency.
Pioneering ubiquitous experience
RetinaMIMO is a new pioneering technology designed to solve the challenge of concurrent ultra-high bandwidth and ubiquitous coverage. It features the industry's first Retina scanning system that allows RF link topologies to be reconstructed to eliminate coverage collapse in the vertical direction. It also adopts a reconstructed antenna array architecture to address the diminishing marginal gains as array elements (AEs) increase.
Based on RetinaMIMO, Huawei has launched the world's first commercial U6 GHz device VitaAAU. Compared with similar products with 1024 AEs, VitaAAU widens coverage by about 30%, enabling U6 GHz to match C-band in both horizontal and vertical directions. This enables operators to deliver U6 GHz coverage for new communications networks on their C-band sites, minimizing overall TCO. To date, VitaAAU has seen commercial adoption in the UAE and other markets, with peak downlink speeds exceeding 10 Gbps, making ubiquitous premium experience a reality.
Pioneering simplified, green networks
Huawei's pioneering EP power amplifier (PA) architecture capitalizes on new materials and technologies to solve the problem of energy efficiency decline on higher frequency bands, maximizing energy conversion efficiency. The industry's first-ever multimode dielectric filters allow antennas to have small dimensions and low power consumption on multi-channel networks with high frequency bands. Powered by new materials, technologies, and architectures, VitaAAU antenna is reduced to 1.5 m in diameter while supporting "0 Bit 0 Watt 0 Loss", delivering superior energy saving efficiency. These innovations enable Huawei's GigaGreen Plus series products to achieve significant reductions in dimensions, weight, and power consumption, better positioned to power simplified and green networks.
Pioneering superior spectral efficiency
Multi-band, multi-cell, and multi-user interference is a major restrictive factor of capacity. The time scaling of the Tau (τ) law is introduced to base stations for the first time to realize optimal dynamic resource scheduling across all domains based on the OSCAR solution. With low-latency bus and high-speed interconnect technology, a high-speed architecture is built to enable the real-time exchange of massive data. Thanks to software and hardware synergy, new UBBPi series products improve average user experience by 1.3 times while reducing power consumption by approximately 40%, further improving spectral and energy efficiency.
Pioneering open-source autonomous networks
Autonomous networks have emerged as an inevitable choice to deal with the growing AI services and increasing network complexity. RANSpirit is another industry first from Huawei, implementing single-domain network autonomy based on the telecom foundation model and digital twins. To date, RANSpirit is serving more than 1.2 million cells across 25 networks around the world, providing assistance to more than 2,000 engineers.
Extensive agent collaboration relies on an open, win-win ecosystem. This galvanizes Huawei to join industry partners to develop ecosystem standards, communities, and industry alliances. In terms of standards, Huawei adapts to the TM Forum, building a cross-agent foundation on the A2A-T standard and framework agreed upon by the industry. In terms of communities, Huawei jointly promotes neutral open-source communities and donates open-source agent components to the Linux Foundation, driving global collaboration and innovation. With regard to industry alliances, Huawei has taken the initiative to pool ecosystem strengths to accelerate business implementation based on the GSMA industry platform.
Fang concluded with the reiteration of Huawei's unswerving pursuit of dual-drive innovation to promote new breakthroughs in mobile networks and work with partners from around the world to deepen the OpenAN ecosystem, advancing new communications networks through technological innovation and open collaboration.
FAQs
Q1: Why is it challenging to balance ultra-high bandwidth and ubiquitous coverage?
Ultra-high bandwidth depends on higher frequency bands. As we know, a higher frequency leads to a greater propagation loss of electromagnetic waves and a weaker ability for them to penetrate obstacles, because high-frequency signals attenuate fast and have short coverage distances, while ubiquitous coverage requires signals to travel a long distance in complex environments. Inherently, the two priorities pull in sharply opposite directions.
