Oppo has published a white paper describing the principles and plans for what it calls a zero-power communication system.
Direct translation can be confusing, but in fact the essence is quite simple and not new. We are talking about devices without a battery, which are powered from external sources. For example, by converting a Wi-Fi signal or some other radio frequency signal.
So far, Oppo is talking primarily about low-power solutions in the Internet of Things segment. First of all, these are various sensors and other similar devices. For example, Samsung recently showed a new remote control for TVs that can be powered by a solar panel or by converting a Wi-Fi signal.
Oppo has already tested the technology and will start promoting the related communication protocol in the future.
