Recently, the world’s third-largest smartphone maker Xiaomi pulled a surprise by unveiling “Mi Air Charge Technology” that the tech company claim it’s designed to deliver 5 watts power to a good number of devices “within a radius of several metres”. However, the development saw the invitation of customers by the Chinese tech giant to experience a “true wireless charging era”.

According to the company’s publication, it claimed it has self-developed an isolated charging pile that boasts of five-phase interference antennas built-in, which “accurately detect the location of the smartphone” from its position.

To ascertain the system’s functionality, a phase control array which consists of 144 antennas transmits millimeter-wide waves directly to the phone with the aid of beamforming, it claimed, adding that “in the near future” it also claimed the system will be able to work with smartwatches, bracelets including other wearable devices.

The Chinese tech company went further to describe the mechanics of its latest tech:

“On the smartphone side, Xiaomi has also developed a miniaturized antenna array with built-in “beacon antenna” and “receiving antenna array”. It was also noted that the beacon antenna broadcasts position information with low power consumption. While on the other hand, the receiving antenna array composed of 14 antennas converts the millimeter-wave signal that is emitted by the charging pile into electric energy via its rectifier circuit, in order to enable the sci-fi charging experience into reality.

Prior to Xiaomi pulling its latest, the subject company had introduced 80W and 120W wireless charging technology, but had made it clear that the new system will not be accessible by its customers this year, the company’s spokesperson said.

While at the moment, its current remote charging technology boasts 5-watt remote charging for a single device within a radius of several meters. This can also accommodate a good number of devices at the same time (with each supporting 5 watts), and even physical obstacles do not reduce the charging efficiency”.

Elsewhere, a U.S. tech giant Motorola according to the company’s executive reported that its executive equally demonstrated a prototype remote charging system that appears to deliver power over the air, but isn’t yet available to consumers.
