Ericsson is making strides in sustainability by designing a proof-of-concept solar-powered 5G site integrated with Lithium-ion batteries that last up to 24 hours. The site continuously optimizes for the best energy source with a unified intelligent management system and power management, including solar power and Lithium-ion batteries,
This proof-of-concept site, which was deployed in Plano, TX, showcases the latest in hybrid energy management. The site will use batteries when electricity rates are high and recharge the batteries when electricity rates are lower.
“This dynamic strategy allows for multiple daily cycles, ensuring optimal cost efficiency by taking advantage of the most favorable electricity prices,” Ericsson said. “The site highlights Ericsson’s ability to offer a complete solution for an energy-smart network by implementing hybrid energy management, renewable energy sources, and energy savings strategies while enhancing grid resiliency.”
The site includes the mid-band Massive MIMO AIR 6419 TDD radios, which are 20 percent more energy efficient than the previous generation; a RAN processor 6651 along with Enclosure 6160, which comprises a solar shelf 6670, lithium-ion Batteries 6612, and Controller 6610 for hybrid energy operation and control.
The radios at the site are turned off when not in use, using AI/ML software, according to Paul Challoner, Head of New Products, Ericsson North America. “Most of the energy usage at a cell site comes from the radio,” he said.
Phase two of the project will introduce alternative green energy sources, such as hydrogen-based generators. Additionally, the Ericsson Network Manager will have features, such as the policy-based battery saver, that allow operators to switch off specified radio frequencies to reduce energy consumption.
