Huawei unveiled U6GHz full-series 5G-A solutions and open-sourced the A2A-T protocol at MWC 2026, targeting AI-driven network demands and 6G evolution.
Huawei has unveiled its full-series U6GHz 5G-Advanced (5G-A) solutions and launched the open-source A2A-T (Agent-to-Agent for Telecom) protocol at Mobile World Congress 2026 in Barcelona, positioning itself at the forefront of AI-driven network evolution.
The telecommunications giant's latest announcement comes as global mobile networks face unprecedented pressure from the explosive growth of artificial intelligence applications. According to IDC data cited by Huawei, monthly active AI users have surpassed one billion in the past year, with AI smartphones now representing over half of new device shipments. Emerging AI terminals like smart glasses are growing at annual rates exceeding 50%, while token consumption has surged hundreds of times year-over-year.
These developments are fundamentally reshaping network requirements. Multimodal AI interactions are driving uplink demand three to five times higher than traditional applications. Real-time AI decision-making demands ultra-low latency and deterministic performance. Perhaps most critically, ubiquitous intelligent agents require more secure and reliable wide-area connectivity than ever before.
U6GHz: The Critical Spectrum Resource for 5G-A
The U6GHz band (6 GHz spectrum) has emerged as a critical resource for 5G-A deployment and commercialization. Since the World Radiocommunication Conference 2023 (WRC-23), U6GHz has been identified as a key global spectrum band for mobile communications. Countries including China, the UAE, Brazil, and several European markets are actively advancing spectrum identification, allocation, and testing.
On the device side, mainstream customer-premises equipment (CPE) and smartphones supporting U6GHz are expected to enter commercial markets in 2026, paving the way for large-scale adoption. This timeline aligns with Huawei's product launch, suggesting the company is positioning itself to capitalize on the imminent commercial rollout.
Full-Series Product Portfolio
Huawei's newly launched U6GHz full-scenario portfolio spans macro base stations, small cells, and microwave transmission products, forming a comprehensive solution matrix. The lineup is designed to activate the ultra-wide bandwidth advantages of U6GHz and precisely address AI-driven demands for high capacity, low latency, and premium user experience.
For outdoor coverage and capacity enhancement, Huawei introduced a series of AAU (Active Antenna Unit) products. The U6GHz 256TRx AAU leverages ultra-large-scale antenna arrays and hybrid digital-analog intelligent beamforming algorithms to deliver coverage comparable to C-band. With advanced MU-MIMO algorithms and 400 MHz ultra-wide bandwidth, it can achieve downlink speeds of up to 100 Gbps and uplink speeds exceeding 10 Gbps in capacity scenarios, while delivering user experiences of 10 Gbps downlink and 1 Gbps uplink.
The company will also provide flexible AAU configurations with different channel and array combinations to support diverse deployment scenarios, helping operators scale 5G-A networks in the U6GHz band to meet the needs of the mobile AI era.
For indoor high-concurrency and high-capacity AI applications, Huawei launched U6GHz small cell products supporting 400 MHz bandwidth. These solutions integrate U6GHz and Sub-6GHz bands, enabling coordinated full-band operation. With simplified design and streamlined deployment, the system ensures consistent multi-dimensional user experience across indoor and outdoor environments.
On the transport layer, Huawei introduced new microwave products tailored for U6GHz base stations' large-bandwidth transmission requirements. Featuring an industry-unique full-duplex technology, the solution significantly enhances bearer network bandwidth and capacity. It not only meets peak traffic demands in the 5G-A era but also lays a solid foundation for future 6G evolution.
A2A-T Protocol: Standardizing Agent Communication
In parallel with its network hardware innovations, Huawei is advancing industry collaboration in autonomous networks through the A2A-T protocol. On February 6, 2026, global telecom partners jointly released the beta version of the A2A-T protocol (IG1453) and its enhanced prompt meta-model IG1453A at TM Forum Accelerate Week.
The protocol aims to provide a unified interaction framework for multi-agent collaboration, addressing key challenges in automated operations such as collaboration efficiency, reliability, and security. As a standardized agent interaction protocol, A2A-T represents a new stage in telecom-grade agent communication.
Huawei announced it will open source the core supporting software for the A2A-T protocol during MWC 2026. The open-source project will include an A2A-T Protocol SDK for standardized agent interaction, a Registry Center supporting authentication and capability management for multiple agents, and an Orchestration Center that enables low-code or no-code visual workflow orchestration with pre-built high-value solution packages.
The A2A-T protocol delivers three major breakthroughs: dramatically improving integration efficiency by reducing system integration cycles from months to days; enabling complex cross-domain and cross-vendor workflows; and accelerating ecosystem convergence by lowering interconnection barriers through unified standards.
Strategic Implications
Facing the surging wave of AI development, Huawei positions U6GHz as a pivotal lever for both present capacity challenges and future innovation. With commercial-ready U6GHz products and an open, collaborative approach to autonomous networking standards, Huawei aims to create new growth opportunities for operators and build a robust connectivity foundation for the accelerated arrival of the intelligent world.
The timing of this announcement is significant. As operators worldwide prepare for 5G-A commercialization and begin planning for 6G evolution, Huawei is offering a comprehensive solution that addresses both immediate capacity needs and long-term technological transformation. The open-sourcing of the A2A-T protocol also signals Huawei's commitment to industry collaboration, potentially positioning the company as a key enabler of the emerging Agentic Internet era.
For operators, Huawei's U6GHz solutions offer a path to monetize the growing AI traffic while preparing for the next generation of intelligent applications. For the broader industry, the A2A-T protocol could become a foundational standard for multi-agent collaboration in telecom networks, potentially accelerating the development of truly autonomous network operations.
As AI continues to reshape the telecommunications landscape, Huawei's dual approach—combining cutting-edge hardware with open software standards—demonstrates a comprehensive strategy for navigating the transition to AI-native networks. The success of this approach will likely influence how the industry addresses the complex challenges of supporting the next wave of intelligent applications and services.
