Xiaomi today has teased a new form of wireless technology that does allow users to remotely charge their phones. This technology has been developed by Xiaomi and uses has five phase interference antennas built-in, which can accurately detect the location of the smartphone. The mobile phone receives the wireless charge by a phase control array that has got 144 antennas and transmits millimeter-wide waves directly to the phone through beamforming.
On the supported smartphone, there is a miniaturized antenna array with a built-in “beacon antenna” and “receiving antenna array”. The function of the beacon antenna is to broadcast position information with low power consumption. The phone has 14 receiving antennas that convert the millimeter-wave signal emitted by the charging pile into electric energy through the rectifier circuit, to turn the sci-fi charging experience into reality.
As of now, Xiaomi is testing 5-watt charging with this technology for one device in a radius of several meters. The company also says that the charger can charge multiple devices at once with each device supporting 5 watts. Xiaomi says that the technology will be enforced in smartwatches, bracelets, and other wearable devices as well. Xiaomi plans to put this technology inside speakers, desk lamps, and other small smart home products, which will all be built upon a wireless power supply design, completely free of wires, making your living rooms truly wireless.
