PRESS RELEASE: AI, as the key driver of technological and industrial advancements, is revolutionizing both lifestyles and production methods across various sectors, including wireless networks.
With the advent of AI-powered networks, wireless infrastructure is also unavoidably evolving to enable higher levels of intelligence. Sites are essential to wireless communications systems, and building digital sites is the first step in building intelligent mobile networks.
Prior to the 2025 Mobile World Congress (MWC) kicking off on March 3 in Barcelona, Huawei’s Ambient Site, a unique full-domain site digitalization solution, was already in commercial use and has been rapidly popularizing globally. Embodying the latest innovations in power supply, transmission, and antenna systems, this solution can facilitate the development of digital sites which constitute the intelligent foundation for wireless networks.
Core Innovation: Bringing AI to Sites
Ambient Site is designed to drive the full digitalization of wireless networks. It links the power supply, transmission, and antenna systems of sites with base station BBUs and RRUs to make sites fully visible, sensible, and controllable. This leads to higher energy efficiency and better user experience, while also accelerating the evolution to Autonomous Network Level 4 (AN L4) to meet diverse service needs in the mobile AI era.
Ambient Site integrates cutting-edge wireless intelligence technologies with digital sites. It upgrades site power systems from mere energy sources to intelligent systems that collaborate across the entire energy chain — from transmission and conversion to storage and base station consumption. This pioneering approach enables unified management of wireless networks and energy solutions, including solar energy and diesel generators. In addition, this solution achieves seamless collaboration among network power systems, base station services, and power grids. This synergy guarantees continuous service availability and quick response within seconds for grid load balancing, supporting intelligent peak shaving and frequency regulation. Huawei has developed Single SitePower, a fully digital power supply solution for sites, and unveiled it at this year’s MWC. This solution aims to help operators build more energy-efficient, resilient, and secure wireless networks.
Intelligent O&M: Maximizing Efficiency with Minimal Costs
As networks scale up, the conventional O&M model falls short of routine needs. Ambient Site provides radio access network (RAN) agents for efficient O&M, built on a full-domain digital, sensible, and controllable foundation and a cloud-based AI-driven telecom foundation model. These agents significantly improve fault prediction accuracy and rectification efficiency, for fewer manual interventions are entailed.
Huawei’s site power supply solution is the first-of-its-kind to offer intelligent tracking of grid power outages. During base station breakdown caused by power outages, the solution intelligently adjusts the charge and discharge of backup batteries, and shuts down non-critical loads when battery capacity is critically low to ensure service continuity, thereby enhancing network resilience.
Value Redefinition: Shifting from Pure Energy Consumption to Energy Prosumer
In addition to technological innovations, Ambient Site unlocks new business value for mobile networks. It slashes energy costs, which are a significant portion of operators’ operational expenditure (OPEX). Single SitePower assists in fluctuation stabilization, peak shaving, and frequency regulation for power grids by coordinating photovoltaics (PV) power systems, highly reliable lithium battery energy storage systems, wireless network loads, and power transmission grids around the world. This results in lower electricity costs, while creating new revenue streams for operators, enabling them to shift from pure energy consumers to both producers and consumers.
Green Energy: Building Sustainable Future Networks
Site power supply is crucial for energy saving. Huawei’s site power system achieves an unparalleled conversion efficiency of 98%, which reduces energy loss by four times compared with older modules with 92% efficiency. It also introduces intelligent voltage boosting to power distribution, reducing the line loss of remote modules by over 10%. The system collaborates with main equipment to intelligently shut down certain modules when the service load is low and promptly wake them up during service bursts, ensuring optimal service experience. Moreover, it supports smooth introduction of PV power, reducing carbon emissions and achieving sustainable target networks.
Success Stories: Unleashing the Power of Innovation Worldwide
Ambient Site has been widely deployed across Asia, Europe, Africa, and America, earning widespread recognition from operators for its innovative technologies. Its digital power supply has been extensively used in China to enable super dormancy and on-demand wakeup of base stations, reducing the energy consumption of an entire site by 10%. In Europe and Africa, Ambient Site has been adopted to cope with power shortages through adaptive power backup, peak staggering, and shaving, increasing site availability from approximately 70% to 99%. In Latin America, iSDUs have been deployed at thousands of sites for adaptive voltage boosting in coordination with services. The modules support future evolution to 5G-A, and reduce delivery costs by eliminating the need for cable changes. In some European countries, including Romania and Finland, operators use the virtual power plant (VPP) solution of digital power supply to lower OPEX and gain extra economic benefits from carbon trading, achieving financial success while fulfilling their social responsibilities.
As the mobile industry embraces AI, operators must prepare their networks for intelligent transformation. In the coming year, more operators will choose Ambient Site to improve user experience, minimize site investments, and lay a cornerstone for intelligent evolution. Huawei will persist in innovation to help operators worldwide expedite their evolution to AN L4, enhance automated O&M, and achieve top-notch network efficiency and user experience.
