Ericsson and PowerLight demonstrate world’s first wireless powered 5G base station

Via Ericsson press room

Oct 4, 2021

As a result of Ericsson’s constant pursuit of new technology to improve the deployment of Radio Access Network (RAN) sites, the company has teamed up with U.S. laser innovator, PowerLight Technologies, to achieve the first safe, fully wireless-powered 5G base station.

The proof-of-concept (PoC) demo milestone was achieved recently in Seattle using optical beaming – a laser-based technology that converts electricity into high-intensity light which is then captured and transformed to electricity at the radio base station.

No wires were connected to the site from the street power grid network and no on-site power generation was involved. The base station site was completely ‘powerless’ until wirelessly powered over the air through a laser beam.

The achievement is part of a partnership between the two companies to explore and develop innovative 5G solutions aimed at enhancing the speed and flexibility of network deployment in diverse environments.

Wireless power was safely distributed to an Ericsson Streetmacro 6701 – a 5G millimeter wave (mmWave) radio base station. It was achieved using PowerLight’s laser technology to transmit hundreds of watts over hundreds of meters through the air.

Ericsson and PowerLight Technologies view the milestone as a major step toward a goal — for subsequent generations of the solution to transmit kilowatts of energy over longer distances.

Kevin Zvokel, Head of Networks for Ericsson North America, says: “Both PowerLight and Ericsson are focused on innovation. This opens new possibilities for Ericsson and our customers. The ability to safely transfer power across distances without having to be connected to the power grid eliminates one of the big obstacles we have when building new cell sites. The time savings and flexibility gains will make this an attractive solution for our customers.”

Claes Olsson, Executive Chairman, PowerLight Technologies, says: “Most people are aware that wireless charging technology is available today for small electronic devices, such as cell phones and watches. This breakthrough demonstration, which utilized the best innovative technology from PowerLight and Ericsson, underscores the major leaps we have made recently toward the commercialization of safe, wireless power transmission for larger-scale systems. PowerLight is developing systems today to transfer kilowatts of safe power over distances of kilometers that will be commercially available in the next few years.”
