Here's what Motorola and Xiaomi say about the safety of their innovative remote wireless charging systems.
They were among the most talked about news of the beginning of this year: Xiaomi first, and Motorola later, announced their new remote wireless charging technologies, allowing us to take a look at what is to come in the future of mobile telephony.
There has been a lot of talk about these two new charging systems, and we still have a lot left doubts regarding its operation. However, one of the most repeated questions in this regard is how safe is this technology really. And, although neither company has wanted get wet In this regard, we can extract certain information from the technical documentation provided by both Xiaomi and Motorola.
Motorola bets on the Qi standard, while Xiaomi develops its own technology
Although similar, the technologies presented a few days ago by Xiaomi and Motorola have important architectural differences. In the case of Xiaomi, we are talking about a ** proprietary technology, based on a matrix of phase interference antennas integrated into the charging base, which allow detecting the devices to be charged and emitting millimeter waves charged with electricity towards them. These, in turn, will receive energy through another array of antennas responsible for capturing it and sending it to the battery.
Instead, the solution devised by Lenovo and Motorola is somewhat different. And is that Chinese companies bet on a technology derived from the Qi standard –The one used by practically all mobile phones with wireless charging today–, which allows devices to be charged at a maximum distance between 80 centimeters and 1 meter. In the case of Xiaomi, the distance is extended to several meters –How many have not been specified–.
But despite the differences in the technologies used, both Xiaomi and Motorola assure a 5W maximum charging power. This power is far from capable of cause harm to a living being, much less a human being.
Furthermore, while both technologies do not appear to be affected by physical obstacles that could be located between the charging base and the device - both Xiaomi and Motorola affirm that the charging speed is not affected by this -, the Gerente general from Lenovo in China issued a statement to clarify that, as a special security measure, if a hand or any other part of the body is identified as being crosses between the signal and the device that is charging, the charging process will stop.
Both companies have ensured that your systems are completely secure. And although no technical details have been offered in this regard, the reality is that there is no reason to think that this technology could be harmful in the medium or long term. Furthermore, it should not be forgotten that today these systems are still in a development phase, and once the moment of its implantation arrives in devices available to consumers, both will have to pass the certifications of the corresponding regulatory bodies.
