Building a Smarter World with 5G-A and U6GHz: Insights from Yang Chaobin of Huawei

Introduction
In a landscape where artificial intelligence (AI) is revolutionizing industries and enhancing consumer experiences at a remarkable pace, Yang Chaobin, CEO of Huawei's ICT Business Group, recently addressed the industry during the Mobile World Congress (MWC) in Barcelona, sharing his vision for advancing 5G-A and the U6GHz spectrum. His call to action reflects the urgent need for the ICT sector to ensure equitable access to emerging AI technologies, emphasizing that 5G-A is pivotal in bridging generational gaps and unlocking the full potential of intelligent connectivity.

Networking Demands in the AI Age

Yang highlighted the exponential increase in global token consumption over the past two years, which has surged nearly 300 times. "The intelligent era is rapidly approaching. Every day brings forth new AI applications, and it is crucial for the industry to unite and leverage the potential of 5G-A effectively," he stated. He pointed out that with the introduction of new frequency bands, such as U6 GHz, the time is ripe to create significant value within the industry and pave the way for the evolution towards 6G.

He argued that connectivity models must evolve from a downlink-focused approach to providing ultra-high throughput for both uplink and downlink communications. Such advancements will facilitate multimodal data exchange between devices and cloud systems for AI applications. Yang emphasized that networks must deliver secure, reliable, and ultra-low latency communications to support real-time AI collaboration and intelligent decision-making.

Closing the Generational Gap through 5G-A

The rapid evolution of AI is significantly reducing the gaps in network capabilities linked to mobile communication between generations. Yang noted that 5G-A serves not only as a connection bridge across different generations but also adapts its capabilities to meet the dynamic market needs. Huawei's commitment to laying the groundwork for 6G technology is evident in its collaborative efforts towards achieving consensus on 6G definitions, use cases, and potential technologies, all set against the backdrop of 6G standards expected by 2029.

As the next five years are critical for the development of mobile AI services, Yang stressed, "AI will not wait for us. It is our primary responsibility to determine how to leverage 5G-A networks to meet rapidly evolving demands." He outlined essential objectives that include achieving user-facing throughput of 10 Gb/s and uplink speeds of 1 Gb/s, compared to the current 4G uplink capacities. Furthermore, he highlighted the introduction of new IoT technologies like RedCap and passive IoT, raising pertinent questions about ensuring fair returns for network investors.

Collaboration for Future Innovations

Looking ahead, Yang urged for collaborative efforts within the industry to meet the surging demands brought on by AI advancements. As boundaries of technology are explored, it is also vital to address global disparities in development. He underscored that approximately 300 million people are still without mobile network access, anxious about a growing digital divide that could widen with the accelerating pace of AI.

Addressing this challenge requires continuous innovation, including diverse frequency portfolios and designing cost-effective solutions. Huawei’s RuralStar initiative, which has been deployed in over 80 countries, has successfully connected 170 million individuals to the internet, facilitating digital education in Kenya through DigiTruck classrooms, providing financial services to rural areas in Bangladesh, and enabling remote medical care in Argentina.

Implementing 5G-A Solutions with U6GHz

The implementation of 5G-A technology has been realized across more than 300 cities globally, positioning the technology for its next development phase. With limited access to C-band resources in various regions, the U6 GHz band is becoming central to enhancing network bandwidth, now acknowledged as the principal frequency band for future mobile communication as per WRC conclusions, and already supported by mature 5G-A device chips and industry infrastructure.

"The pace of the intelligent era is accelerating. In the next five years, we must work together to meet the demands for AI services by commercializing 5G-A on a grand scale," Yang concluded.
