Abstract
Various embodiments of the present disclosure describe radio frequency (RF) enabled devices, system, and RF energy relaying techniques for selectively harvesting and/or relaying RF energy signals. An RF-enabled device may include an antenna unit configured to receive a radio frequency signal and a switch component electrically coupled to the antenna unit. The switch component may be associated with a plurality of signal processing states that include at least a collection state and a reflection state. The RF-enabled device may include a controller that is configured to selectively transition the switch component between the collection state and the reflection state based at least in part on one or more power transfer stimuli. At a collection state, an RF energy signal may be harvested. At a reflection state, the RF energy signal may be reflected to another entity within a proximity to the RF-enabled device.
