  • Publication number: 20080227478
    Abstract: A method and a system include a converter configured to convert received radio frequency signals to a direct current (DC) signal to provide power to at least a portion of a receiver. A received radio frequency signal can be associated with a plurality of carrier frequencies within a specified frequency band and time period. The received radio signals can have a total power level above a threshold power level. In some embodiments, the total power level can be above a threshold power level and below a pre-determined power level. Multiple converters can be used. Each converter can correspond to a subset of the carrier frequencies and/or to the carrier frequencies of different specified frequency bands. A combiner can combine the DC output from the converters into a single DC signal. The receiver can communicate data via a data carrier frequency associated with the carrier frequencies used for wireless power transfer.
