Start-up touts wireless charging from Wi-Fi and Bluetooth signals

Lucas Mearian | April 2, 2015
A wireless charging start-up says it has developed a chipset that easily integrates with mobile devices to allow them to charge from existing Wi-Fi and Bluetooth transmitters.

"This pinpoint precision targeting of energy safely and efficiently powers all Cota-equipped devices and batteries within its effective radius, even as they move around the room," Cota said in its marketing material.

Cota claims its technology is "inherently safe." Its tracking beacons use only about 1/10,000th the signal power of Wi-Fi, which itself is a low-power signal.

Cota's energy pockets are created using approximately the same signal strength emitted by a mobile phone during a call.
