Energous in the US has received the first approval for its 15W wireless charging system that the company says works at any distance.

The high power WattUp PowerBridge transmitter has received the first US Federal Communications Commission (FCC) Part 18 grant of equipment authorization for 15 watts of conducted wireless power transfer.

The approval enables higher power transmission for devices in the Internet of Things (IoT) such as electronic shelf labels, sensors and RF-based asset tracking and also acts as a data link. Providing consistent levels of power for IoT devices eliminates the need to manage and change out batteries or power cables.

The PowerBridge transmitter can charge multiple devices simultaneously at-a-distance using RF-based wireless power at 1W, 5.5W and now 15W. Multiple transmitters can be meshed together to create a WattUp wireless power network covering unlimited distances for large footprint deployments such as retail stores, industrial warehouses, manufacturing plants, logistics hubs and more.

“This is a landmark approval for Energous, as it enables us to now transmit 15x more power than previously allowed without distance limitations,” said Cesar Johnston, CEO of Energous. “This achievement is the result of our long-term and continued focus on increasing both power and distance for Wireless Power Networks utilizing our advanced systems ICs.”

Analyst firm IDC projects the number of IoT devices globally to more than triple over the next three years, growing from about 12 billion devices today to almost 40 billion by 2025 and each device requires consistent and reliable levels of power.
