FCC approves first 'power-at-a-distance' wireless charging device

Energous Watt Up

Energous' new wireless transmitter can overcome this limitation by allowing wireless charging from a distance of over three feet.

It's been a while since we last heard anything about Energous.

But now, the Federal Communications Commissions (FCC) has given a green signal to the first wireless charger which is able to charge the device from up to three feet away.

Market Pulse Stories are Rapid-fire, short news bursts on stocks and markets as they move. The technology used by Energous in its wireless charger is different from the resonant induction method used by the Pi wireless charging system. The transmitter will convert electricity into radio frequency and transfer that energy to nearby devices equipped with the receiver.

The wireless standard hasn't yet been specified by the company.

Energous will demonstrate the WattUp charger at next year's CES, which kicks off on January 9 in Las Vegas.

In a major step forward for charging technology, the FCC has certified the first at-a-distance wireless charging system.

Another more promising technology, "Rezence", does "magnetic resonance" charging and allows a greater degree of freedom in regards to where you can place your devices.

This specific system is manufactured similarly to that of normal Wifi which means the transmitter is no way linked to the functioning of the charging system. While companies like Energous may be able to ideal their own systems, these are all but destined to require bulky phone cases to function as a receiver for the near future until phonemakers are enthused enough about the tech to build it into phones directly.

When device makers flaunt wireless charging support there is some charging pad or station involved on which the device needs to be placed. Energous is hoping to relax the rules of wireless charging with the WattUp Mid Field transmitter. We aren't talking about having to sit your smartphone or other device down on a pad to charge them without having to fiddle with wires; that has been available for many years now. All devices have to be outfitted with a specific receiver and now, and multiple devices can be charged simultaneously, within 15 feet of the transmitter.
