Abstract
A system and methodology for intelligent power management of wirelessly networked devices. The system provides for reliable wireless communication via a wireless power charging method and, a method to maintain power capacity of batteries in a wireless device. The batteries are charged via an RF harvesting unit embedded inside the wireless device. An intelligent wireless power charging system further comprises at least two batteries and at least two RF adaptor devices coupled to an AC power line. The first adaptor is set for data communication while the second adaptor is used to transmit the power. In addition, when a first battery is in use during active mode, the second battery is subjected to wireless charging.
