  The company outlines how the technology works in a blog post. The transmitter looks quite large, as large as perhaps a living room side-table next to a couch. The transmitter can provide a 5W charge wirelessly to a smartphone. 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. This kind of charging has nothing to do with the Qi standard. The smartphones need to be outfitted with a “miniaturized antenna array with built-in ‘beacon antenna’ and ‘receiving antenna array’.” The smartphone has 14 antennas to convert a millimeter wave signal that’s emitted by the charging pile. The signal is converted into electric energy through a rectifier circuit. In its current state, Xiaomi’s remote charging technology can charge multiple devices with a 5W current within a radius
