ZTE Case Study
ZTE End-to-End Green 5G Solution
To achieve their commitment to “Net Zero” operators are constantly looking for ways to reduce electricity consumption. In response to the significant increase in power consumption of 5G base stations and the urgent demands of operators for lean and efficient energy solution, ZTE has delved deep into the energy full-chain of sites, made end-to-end energy-saving innovations. In China, Italy, Vietnam, Myanmar, Pakistan, South Africa, Ethiopia, and other countries and regions, ZTE has helped more than 20 operators build more than 500,000 high-efficiency green sites.
Full-Chain Energy-Saving Technical Solution
ZTE harnessed its technological experience in the ICT sector over the last 30 years, by applying advanced technologies such as chips, architectures, and AI algorithms to implement end-to-end green 5G solutions. These innovations include; PowerPilot, an intelligent Radio Access network (RAN), a two-phase liquid cooling router, "zero carbon" communication energy network and a data center with evaporation liquid cooling technology etc.
PowerPilot RAN solution
Combined with AI and big data, ZTE's PowerPilot RAN solution achieves real-time and accurate service, with in-depth collaboration of 4G/5G network, thus effectively reducing network energy consumption and improving efficiency. The ZTE PowerPilot RAN solution has been widely put into commercial use in China, Malaysia, South Africa, Indonesia, Thailand, etc. Since 2019 with a cumulative commercial scale of over 300000 cells. It has demonstrated that the overall prediction accuracy rate for commercial use has reached above 90%, and has reduced the energy consumption of the 4G/5G network over 20% per day. By June 2021, ZTE PowerPilot solution has been put into large-scale commercial use in more than 30 networks around the world, exceeding 800000 sites saving the operator almost 1 billion USD as electricity cost.
Two-Phase Liquid-Cooling Core Router
ZTE has innovatively applied the two-phase liquid-cooling technology in large-capacity core communications equipment. According to the experiment data, the two-phase anhydrous liquid-cooling technology can increase the heat dissipation efficiency of core equipment by 2.5 times, while reducing the energy consumption of the machine room by 30% and the noise by 80%. According to the average absorption of carbon dioxide by a tree of about 5.023kg per day, it is calculated that a single set of equipment using the two-phase liquid-cooling technology can reduce 97 tons of carbon emissions/ year, which is equivalent to planting 53 trees.
“Zero carbon" communication energy network
In Pakistan, ZTE and CMPAK adopted green energy and laid out Smart Lithium batteries on a large scale to reduce the single-site fuel consumption by nearly 100%. The de-oiler measure helped each site reduce on average more than 8 tons of carbon dioxide emissions every year. The network energy management system, allows remote management and intelligent operation and maintenance of all sites.
Green Data Center
ZTE is one of the leading suppliers of modular data center solutions. ZTE applied self-developed technologies, advanced equipment, and AI in key links, such as power supply and distribution, HVAC system, and management system, to improve the power usage efficiency (PUE) of data centers through multi-pronged measures.
