Ericsson tests lasers to deliver electricity to base stations

Ericsson conducted a proof-of-concept (PoC) demonstration that used a laser to beam high-intensity light to a radio base station. The light beam was captured at the base station and transformed to electricity.

The base station site was completely ‘powerless’ until wirelessly powered over the air through a laser beam.

The demo was performed in Seattle using 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.

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.”

BridgeComm pushes Free Space Optical to 100 Gbps

BridgeComm will demonstrated its point-to-point free space optical solution operating at speeds beyond 100 Gbps at the Hampton Inn in Sneads Ferry, NC, in conjunction with a global conference April 6-15. The demo is enabled by BridgeComm's extensive work in free space optical technology and Nokia's network equipment and services backed by Nokia Bell Labs.

"We are excited to bring our point-to-point (P2P) technology out of the lab and in front of customers," said Barry Matsumori, BridgeComm CEO. "By incorporating our optical wireless communications with Nokia's industry-leading infrastructure telecommunication tools, we can support the diverse demands for data, speed and security end-users require beyond the reach of fiber and without the compromises of radio communications."

BridgeComm and Nokia will leverage existing commercial technology to design, construct and operate a private wireless network. The largely virtualized network will be based on standardized 3GPP architectures and allow for a cost-efficient yet highly scalable network testbed that will enable rapid experimentation of applications. Each connected private wireless location will
