On the eve of MWC Barcelona 2026, Huawei introduced its 5G-A Mobile Backhaul (MBH) network architecture, purpose-built for the Agentic Mobile Broadband era.
Defined by core capabilities such as 10GE and 25GE to the site, Layer 3 routing to the site, and end-to-end SRv6, the new architecture is designed to strengthen differentiated experience assurance and enable operators to shift toward experience-based monetization models.
Experience Monetization Drives the 5G-A Evolution
While 4G centered on connecting people and traditional 5G expanded into IoT connectivity, 5G-Advanced represents a leap toward an Intelligent Internet of Everything integrated with sensing and communication.
This evolution is transforming operator business models. Instead of focusing purely on traffic growth, operators are increasingly monetizing premium user experiences based on ultra-high bandwidth, strong fault protection and deterministic Service Level Agreement assurance.
To support this shift, Huawei has redefined the mobile backhaul network from a best-effort forwarding model to a deterministic transport architecture that ensures predictable performance for advanced services.
Three Bottlenecks in Traditional Backhaul Networks
As 5G-A scales globally, conventional mobile backhaul networks face three major constraints:
1. Constrained Interface Rates
The rise of Ultra-HD video, 8K streaming and 3D live broadcasting has pushed 5G-A base station peak throughput beyond 8Gbps. Traditional GE-to-site links are becoming bottlenecks, limiting the ability to deliver lossless high-speed backhaul.
2. Inflexible Network Routing
More than half of access devices still rely on Layer 2 switching, forcing cross-site traffic into inefficient routing paths. This architecture struggles to meet ultra-low latency requirements for mission-critical services such as industrial automation and low-altitude economy applications.
3. Limited Differentiated Experience Assurance
Emerging sectors including autonomous driving and low-altitude economy services demand high reliability, flexible scheduling and deterministic transmission. Legacy backhaul networks lack the programmability and reliability needed to guarantee such advanced requirements.
Three Core Capabilities of Huawei’s 5G-A MBH Architecture
To address these challenges, Huawei’s new 5G-A mobile backhaul architecture introduces three transformative capabilities.
10GE and 25GE to the Site
By upgrading access-layer links to 10GE and 25GE, Huawei enables a lossless backhaul pipeline for 5G-A base stations. This unleashes the full 10Gbps potential of the wireless air interface and supports premium services such as HD live streaming, 8K video, XR and AI vision applications.
The enhanced bandwidth capacity allows operators to expand value-added services and drive higher Average Revenue Per User.
L3 to the Site
Deploying Layer 3 routing capabilities directly to the edge enables shortest-path forwarding between base stations. This significantly reduces latency and supports time-sensitive applications.
It also creates new opportunities for B2B services including industrial control systems, edge computing and low-altitude economy use cases, expanding operator revenue streams beyond consumer connectivity.
End-to-End SRv6
End-to-end SRv6 introduces minute-level network traffic scheduling and intelligent congestion management. During traffic surges, the system performs global optimization to release suppressed traffic, helping operators increase Data Over Usage by more than 20 percent.
This capability ensures high-quality service delivery even under heavy network load.
Proven Commercial Deployment
Huawei’s 5G-A mobile backhaul solution has already entered large-scale commercial deployment.
In China, a demonstration zone upgraded from 10GE to 25GE at the access layer, accelerating the rollout of high-quality naked-eye 3D, XR and AI-driven services.
In South Africa, an operator implemented Huawei’s end-to-end SRv6 solution to achieve real-time traffic optimization. By releasing suppressed traffic, Average Revenue Per User increased from $18 to $25, demonstrating the commercial value of experience-based operations.
From Data Pipe to Experience Foundation The evolution to 5G-A backhaul is more than a capacity upgrade. It represents a fundamental transformation from a traditional data transport pipe to a foundational platform for differentiated experience assurance.
