For the presentation of its new technology, Lei Jun's company went down hard. The post and the teaser published on Weibo, in fact, referred to ainnovation epoch-making technology. In the past few hours we have talked about the wireless charging from 67W - of which the MIUI 12.5 he anticipated the logo - but the good DigitalChatStation he thought of putting the flea in the ear of the fans.


The well-known Chinese leaker immediately anticipated the arrival of Xiaomi Air Charge albeit remaining vague, without going into the details of this novelty.

Inside the remote charging tower I am present 5 antennas built-in phase detection: these allow you to locate the position of one or more smartphones in a handful of milliseconds. A phase control array, consisting of 144 antennas, transmits millimeter waves directly to the smartphone through beamforming.

Obviously there will be a need for compatible devices, whether they are telephones or other terminals. On the smartphone side, Xiaomi has developed a miniaturized antenna array with integrated "beacon antenna" and "receiving antenna array". The beacon antenna transmits position information with low power consumption. The receiving array, consisting of 14 antennas, converts the millimeter-wave signal emitted by the charging tower into electrical energy through a rectifier circuit, to transform this sci-fi experience into reality.

The video you see above shows the new technology in action: at the moment this novelty is able to load multiple smartphones at the same time, with a maximum power of 5W (per device), within a radius of several meters.
