Traditional wireless chargers still need to be attached to a power source or charging pad. The latest technology from Xiaomi uses radio waves to charge a device over the air --which makes it truly without wires. The system uses a base station with 144 antennas broadcasting a charging signal to compatible devices nearby.

Xiaomi says that a smartphone with a receiving antenna array can connect to the charging point "within a radius of around 10 meters." The company says that users can move about the room and have objects between the devices without interrupting the charging process.

A millimeter-wave signal is broadcasted directly to the device via beamforming with a beacon antenna. The device can charge multiple phones at 5W of power each. 

Note: This is just under development, so want to get adjusted to 5W😝 

Xiaomi hopes to use this technology in smartwatches, speakers, smart Tv, and other appliances so that future devices no longer need a power cable at all, Every this thing will be wireless. Sounds great right😃 .

Now just imagine a world where everything in the room is truly wireless. Isn't this the real "truly wireless " technology?

And after that Oppo also introduced its wireless charging system with its Oppo rollable smartphone Globally.

This technology will be very innovative and helpful in all these busy schedules. Now, this technology is at the initial stage, so it has many limitations. 

Let's hope that this technology may grow and soon will be available at retails.
