Abstract
Systems and methods for ambient electromagnetic power harvesting (AEPH) chip reader-writer devices are provided that selectively control RF parameters of electro-magnetic (EM) signals transmitted to an AEPH chip. In embodiments, the selection of which RF parameter configuration is applied when transmitting an EM signal is determined by an RF parameter selection processor based on the function being invoked from the AEPH chip. In one embodiment, an AEPH chip reader-writer selects a first configuration of radio frequency (RF) parameters from a plurality of RF parameters based on a determination of a first operation for execution by an ambient electromagnetic power harvesting chip; configures an RF transmit path circuit to use the first configuration of RF parameters; and initiates execution of the first operation in the ambient electromagnetic power harvesting chip by transmitting via the RF transmit path circuit a first electromagnetic signal using the first configuration of RF parameters.
