Huawei unveiled upgrades to its mobile transport (backhaul) solution aimed at the evolution to 5G-Advanced (5G-A) and 6G at the Mobile World Congress (MWC 2026) in Barcelona, Spain.
On Mar. 2 local time, Huawei said it would advance transport networks around three core values—"green ultra-broadband," "congestion awareness," and "network autonomy"—to meet transport conditions required by new service scenarios.
Huawei cited the surge in traffic driven by the spread of the upper 6GHz (U6G) band as a structural challenge for transport networks. More than 20 countries are currently allocating U6G spectrum to mobile networks, and, with its wide bandwidth and coverage, it supports 5G-A's speed performance and user experience, the company said.
Huawei projected that 5G-A will provide ultrafast connectivity tailored to demand such as mobile XR and cloud-based immersive collaboration, and that user-perceived speeds could reach 10 Gbps or higher.
The problem is the transport network. With service sophistication expected to increase transport network traffic more than tenfold, expanding basic bandwidth capacity is essential, Huawei said. Existing transport networks have complex topologies mixing microwave and optical fiber L.I.N.C and are vulnerable to bandwidth fluctuations due to weather conditions. If localized traffic growth triggers congestion, user experience deteriorates and it negatively affects data usage (DoU), the company said.
As the first solution, Huawei proposed "green ultra-broadband." The new base station router provides 10GE/25GE per site and 100GE on the access ring, and is designed to scale to 400GE. By integrating energy-saving technologies, it said it can cut total cost of ownership (TCO) by 30% and save about 3 million kWh of electricity over three years for 1,000 units.
Second, "congestion awareness" combines SRv6 with the NCE intelligent management and control system to identify congestion points and automatically generate optimization and expansion recommendations. It said this relieves suppressed traffic to improve user experience and helps increase DoU by more than 20%.
Third, "network autonomy" focuses on detecting optical fiber faults within minutes using built-in OTDR and self-diagnosis algorithms, reducing field dispatches and improving operations and maintenance efficiency by 20%.
Huawei said the solution aims to support commercial monetization of 5G-A while protecting long-term investment in preparation for 6G evolution. It plans to continue innovating toward ultra-high bandwidth, ultra-high-precision clocks, and deterministic ultra-low latency, backing the buildout of "agentic MBB."
