Aaron Jiang, President of Huawei's SRAN Product Line, launched the GreenSite and PowerStar2.0 solutions to help operators build green, low-carbon 5G networks in Dubai.
According to a press release, the GreenSite solution integrates innovative architecture, site construction, and algorithms with leading-edge software and hardware, improving energy efficiency by 20 times.
The PowerStar2.0 solution introduces new intelligent energy-saving features to base stations and networks to reduce energy consumption by over 25% through multi-dimensional coordination under typical configurations.
According to the release, Huawei's MetaAAU uses ultra-massive antenna arrays to significantly increase antenna gains. Compared with traditional AAU modules, it reduces power consumption by about 30% while providing the same DL coverage.
Huawei ultra-wideband RRU uses ultra-wideband power amplifiers, hardware units, and advanced algorithms to integrate multiple single-band devices into a single box with an ultra-compact form factor. This enables more bands to be supported with the same level of power consumption.
Meanwhile, the air conditioning in equipment rooms constitutes 30–40% of a site's total energy consumption. Huawei offers a new outdoor cabinet APM5950 to help operators simplify site construction. It allows operators to deploy sites outdoors without using equipment rooms and air conditioners (AC), increasing E2E energy efficiency from 60% to 90% while saving 30% of site energy consumption. It also uses solar power and high-cycle lithium batteries to replace diesel generators, further reducing carbon emissions.
Based on a hardware design that favors maximized energy saving, PowerStar2.0 supports shutdown in milliseconds based on service load, helping extend energy-saving periods from off-peak hours to the entire day, it said. It further adapts deep shutdown to the estimated speeds required for network services to improve energy-saving precision. This helps further prolong energy-saving periods while also meeting user experience requirements.
In PowerStar2.0, power control is further used as the fourth dimension of energy-saving beyond the symbol, channel, and carrier levels. The enhancement enables RF modules to transmit less power by increasing scheduling resources, helping ensure user experience, and taking network energy saving to new heights, said the release.
