5G technology is revolutionising the mobile industry, but its realization brings many challenges to the mobile operators. Energy saving, for one, is one of the top priorities. In order to support the green economy, ZTE has developed a new-generation solution that it says can further reduce the power consumption of radio networks, to save up to twice as much energy as the existing energy saving solutions.
Building on its previous innovations in network energy saving, ZTE has developed PowerPilot to bring AI-driven power optimisation to even grander scale of wireless networks. This takes power savings to a new level, moving from single-mode power systems to optimising energy use across both 5G networks and all previous generations (4G, 3G and 2G). What makes this unique is the system can coordinate power consumption among multiple frequency bands and radio access technologies, piloting the traffic to the most suitable layer for optimal energy efficiency across the whole network.
PowerPilot looks at different types of services running over the network and their power requirements and works in real time to choose the most energy-efficient delivery possible. Artificial intelligence and big data are leveraged along with the multi-layer energy-saving technologies across the base stations and O&M system to achieve optimal power consumption without human intervention. This means operators not only save energy, but also free up human resources for core tasks and lower their operating costs at the same time.
ZTE has a long history of commercially deploying network energy solutions, with the following milestones in the past year.
PowerPilot builds on these ZTE innovations to deliver up to twice the energy savings of the existing solutions on the market. Taking an average network configuration of 10,000 sites with 4G and 5G as an example, ZTE estimates that PowerPilot can cut power consumption of 700,000 kWh in a week, equivalent to 550,000 kg of fewer carbon emissions.
ZTE has over 500 patents for environmentally friendly technology, in-house-design chipsets and a new generation of high-efficiency power amplifiers. ZTE’s R&D labs have tested PowerPilot extensively in simulations of multiple types of network, including a variety of frequency bands, traffic loads and other parameters.
