Powercast Corporation has created a unique cellular-based RF Power-Over-Distance Wireless Charging Platform, built around Sequans Monarch cellular IoT connectivity technology.
Operating in the lower 600 – 900 MHz frequency bands licensed by mobile carriers, the Powercast cellular-based RF Wireless Charging Platform has unique benefits.
“Because many RF transmitting devices operate in unlicensed bands such as the 915MHz band, there are limits on transmit power, antenna gain, and other parameters so many devices can coexist and be interoperable,” said Charles Greene, PhD, COO and CTO of Powercast. “This innovative way to use licensed cellular frequencies to increase device charging power will allow manufacturers to create green, sustainable IoT devices that can charge more quickly and at longer distances from a cellular RF transmitter.”
The platform combines Sequans’ Monarch 2 GM02S module with a Powercast RF transmitting antenna to send RF over-the-air to a tiny Powercast PCC110 Powerharvester® receiver chip embedded in end devices. The Powerharvester harvests RF out of the air and converts it to DC (direct current) to either power a battery-free device, or charge a rechargeable battery, both of which keep disposable batteries out of landfills.
“This collaborative effort to introduce cellular technology into the over-the-air RF wireless charging picture creates opportunities for more manufacturers to develop environmentally-friendly smart home IoT ecosystems that eliminate disposable batteries,” said Louis Chuang, EVP and GM of the Massive IoT Business Unit of Sequans. “With cellular everywhere, the opportunities are endless. Powercast is pioneering this field, and shares Sequans’ vision to make IoT more sustainable by integrating an increasing number of functionalities, and limiting the semiconductor carbon footprint.”
