Motorola claims it will have world’s first phones with over-the-air charging

Motorola is making a name for itself with budget smartphones, but that doesn't mean high-end features won't be coming to its smartphone lineup in the future. To that end, the Lenovo-owned phone maker is teaming up with GuRu Wireless, a company specializing in truly over-the-air power delivery.

Yes, that means Motorola plans to have some of its future phones support OTA charging, in which your phone will be able to top up its battery without any wires or need for a charging pad. Motorola even vows that it will have the first phones that can charge over-the-air, though it may be a couple years before the company can make good on that claim.

The technology itself is quite interesting and we had a chance to speak with GuRu CEO Florian Bohn about it. The dream of a wireless life has captured many, but we've yet to see a system thus far live up to the hype and possibility. GuRu has endured through this wave of interest, focusing on coming up with a solution so good that Motorola chose to partner with it.

Over-the-air-charging: How it works

The wireless power solution uses mmWave technology on the 24 GHz band to deliver power to supported devices. While your current phone may contain a Qi coil for your wireless charging pad, it won't be able to accept power from GuRu's generator units. The process will require a separate module in the phone itself.

Speeds will vary depending on what kind of device is receiving the power. Bohn says that phones might get 5 to 10W of power. That seems slow, certainly by today's wired charing standards, which can reach 65W depending on the phone and charger in question. But 5 to 10W of true wireless, over-the-air charging sounds pretty incredible when you consider that you can charge your phone from anywhere in a room. 

Future advancements might allow for faster speeds, but that's looking too far down the line.

GuRu's OTA charging technology seeks the best path to your device, often bouncing off walls and such. There are limitations — you can't set your phone on a metal box and still have it charge, for example.

You might expect range to work a bit like Wi-Fi, where effectiveness decreases the further you get from the source. GuRu's Bohn explained that OTA charging uses what he calls RF Lensing. The technology is focused like a lens, extending its range beyond conventional understanding. It took me a second to wrap my head around this, but I learned that this OTA charging technology can actually be more effective the further it is from the generator unit(s).

Operating on the 24 GHz band means that there isn't likely to be any interference with the OTA power delivery. As for health considerations, Bohn says the technology is safe to humans and it's going through the regulatory process now (which includes health testing). 

Over-the-air charging: When it's coming

In short, we're approaching a truly wireless future. GuRu is understandably excited about its technology and it thinks we'll see this as widespread as Wi-Fi sometime further down the road.

But what about Motorola? We don't know too much about the company's plans beyond that its partnering with GuRu to implement this technology in future devices. We also don't have an official timeline, though we could see a Motorola phone with a GuRu module installed in the next couple of years. Remember that smartphone design takes a longer time than you might think and this is a new technology.

GuRu Wireless medium range charging technology

Motorola has begun a plan to give its smartphones medium-distance charging technology from startup GuRu Wireless that requires not only no charging cables but also no charging pad. The technology beams power 10 feet or more using radio waves sent from a charging hub to devices like phones, laptops and potentially even drones.

The companies announced the partnership Wednesday, though the Lenovo subsidiary didn't detail what products could get the charging technology or when. "With this solution we will provide a glimpse of the freedom and flexibility that users can enjoy with a revolutionary over the air, wireless power technology," said Dan Dery, Motorola's vice president of product, in a statement.

As digital brains pervade everything in our lives, keeping batteries topped up has become more of a concern. Charging pads for phones, watches and earbuds can be convenient, but medium-range wireless charging has the potential to liberate us even from those pads. And nobody likes pausing to plug in video game controllers or running out of power for hearing aids.

The trouble is that medium-range wireless charging hasn't caught on yet, despite efforts from companies like Ossia and Energous. One problem is the classic technology chicken and egg issue: Without widespread charging hubs, there's little incentive for device makers to support the technology, and without device maker support, there's no reason to buy a hub.

GuRu's technology uses 24GHz airwaves -- part of the millimeter wave radio spectrum -- to send power to devices. Charging hubs use lensing technology to beam energy toward devices and can pause transmission when they detect an obstruction. If you move a device, the hub can relocate it within a few seconds.

It can beam power at about 5 to 10 watts, a rate that's not too far from Qi charging pads or lower-end phone chargers. But the technology can also be adapted for much higher power devices, including laptops and drones that need 100 watts, and for longer distances, the company says.

GuRu hubs could be built into ceiling fixtures for a room, conference call speaker systems in offices, smart speakers or other devices. A standalone hub likely would cost about as much as a higher-end Qi charger or Wi-Fi router.

Motorola Wireless Charging

American multinational telecoms firm Motorola has been producing mobile devices since their first handset was released in 1983. They first introduced wireless charging in the Droid MAXX handset in 2013 and produced several further models with the feature in the following years.



The Motorola handsets above are all compatible with Qi wireless chargers such as those found in public spaces and in vehicles, as well as the complete Aircharge range. When using these models, simply place the handset on a Qi wireless charger to start charging.

In Aircharge public spaces, non-Qi handsets can also make use of wireless charging technology through the use of the Aircharge Orb, the world’s first and only MFi Certified multi-head adaptor. Simply plug the required connector into the port and place the orb on the Aircharge surface charger to charge. Alternatively, accessories such as the Aircharge keyring or micro USB receiver can be plugged into the device and placed on a wireless charger to transfer charge to the handset.

During CES at the beginning of the year Motorola demonstrated a new wireless charging technology – unlike typical Qi chargers, it allowed phones to be charged at up 1 meter away (3.3 ft). And it could handle two devices simultaneously. The company has developed the second generation of this technology with much improved capabilities.

Phones can now be charged at up to 3 meters (10 ft) of clear air between them and the charger. It’s one hefty charger equipped with a phased array with with a whopping 1,600 antennas. The charger covers an arc of over 100º, so it can beam power to phones even if they are off to the side.

And since it covers more territory, the new charger can handle up to four phones simultaneously, double what the original device could manage. The charger can even handle some obstructions between it and the phone.

This means that the phone can be charged while it’s in your hand or your pocket. The charger can detect your body and aim the beam away from it so that it hits just the phone.

This last year we’ve seen some competing technologies like Xiaomi’s Mi Air Charge, which uses a 144 antenna array to deliver 5W to a phone “within a few meters”. This one is able to handle two phones simultaneously. There’s also Oppo’s Air Charging tech, which promises up to 7.5W, though it only works at 10 cm (4 in) distance and doesn’t seem to handle multiple devices.
