This is a revolutionary innovation of wireless charging.
This is also a bold attempt to turn the whole house wireless.
It’s not science fiction, it’s technology.
This is Xiaomi’s self-developed remote charging technology.
The core technology of Xiaomi’s remote charging lies in space positioning and energy transmission. Xiaomi’s self-developed isolated charging pile has five phase interference antennas built in, which can accurately detect the location of the smartphone. A phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming.
Currently, Xiaomi remote charging technology is capable of 5-watt remote charging for a single device within a radius of several meters. Apart from that, multiple devices can also be charged at the same time (each device supports 5 watts), and even physical obstacles do not reduce the charging efficiency.
