Original Abstract Submitted
This disclosure provides methods, components, devices and systems for ambient power energizer control. Some aspects more specifically relate to utilizing silent periods during which an energy providing device does not transmit radio frequency (RF) energizing waveform to avoid interference. In some implementations, a reader may transmit a message to an energizer, indicating the time period during which the energizer is to refrain from transmitting the energizing waveform. The reader also may transmit a similar message to one or more tags indicating when the tags should harvest energy and monitor for wakeup signaling. A master device may send coordination information to multiple readers such that each reader and each energizer coordinates silent periods. An energizer may combine multiple patterns of silent time periods to ensure that silent time periods for different readers are aligned. The reader may dynamically trigger energizer waveform transmission.
