charge wirelessly from distance

Wirelessly Charge Devices From 15 Feet Away:

While wireless charging has been with us in consumer form since the Powermat debuted in 2009, current evolution of the technology still sees us tethered to the charging pad. There are, however, a handful of efforts seeking to liberate us from this current predicament and the WattUp appears to be one of the most likely to find success.

Made by Energous, it’s a wireless charging system that uses a mix of Bluetooth, RF signals, and some patent-pending tech to enable sending power wirelessly to devices as far as 15 feet away. That way, you just have to be within the vicinity of the charging device (which, in this case, looks and functions like a bigger WiFi router) in order to get your phones, tablets, and similar gadgets juiced.

The WattUp can work with any battery-operated device that requires less than 10 watts to charge. While that probably rules any current generation of laptops, it should be enough for mobile phones, tablets, and other mobile gadgets. It uses a transmitter called the Power Router, which sends the energy via RF signal to a WattUp receiver pre-installed in the device, which then converts the signal into battery power. Up to 12 receivers can be managed by the Power Router simultaneously, continuously charging them even while the gadgets are in motion, provided they stay within range.

As of now, Energous is working on licensing their technology to other companies who can then integrate it into their own products. They’re releasing a reference design for both the transmitter and the receiver in around six months, which licensees can then use to pattern their own charging systems.

True Mobility

Wire-free power delivers on the promise of true mobility, the freedom to roam where you want to without worrying about your mobile or battery powered devices running out of charge.  While power cords and charging pads require you to surrender your device to a stationary location, WattUp® gives you the freedom to receive a charge from anywhere within a 30-foot end-to-end charging envelope.

Charges Any Battery-Operated Device That Requires Less Than 10 Watts:

WattUp RF-based charging can be integrated to provide wire-free charging to a wide variety of electronic devices such as cell phones, tablets, wearables, cameras, wireless keyboards and mice, headsets, sensors, LED lights, remote controls and toys; in essence any battery-powered device in your home or office.

Works Like Wi-Fi:

A WattUp transmitter, or Power Router, sends energy via a radio frequency (RF) signal to your WattUp-enabled electronic devices when requested. A WattUp receiver in each device converts that signal into battery power.

The entire system is software controlled, so it's intelligent and customizable to your needs and environment. And, because it's designed to work invisibly in the background, WattUp can make low battery anxiety a thing of the past.

How Does it Work?

A Radio Frequency (RF) system, similar to a Wi-Fi system, delivers safe wire-free charging energy at a distance of approximately 15ft from a transmitter to a receiver device, such as a mobile phone, and maintains charging while the receiver is in motion.  12 receiver devices can be managed by the system simultaneously.

The Hardware:

Highly targeted pockets of energy are delivered via multiple miniature antenna arrays and custom control chips in the transmitter, or Power Router.  Energy harvesting of the micro energy beams from these pockets then takes place via paired antenna arrays and custom chips in the receiver devices.(from coolthings.com)

The Software:

The WattUp® software system ensures that the charging waveforms are dynamically directed, focused and controlled via proprietary algorithms.  Charging and communication between transmitters and receivers is intelligently managed using BLE and enterprise-class wireless networking protocols.
