Rf communication device with energy enhancement

Abstract

A method of operating a radio frequency (RF) communication device includes internally storing energy received by the RF communication device, and using that energy to enhance communication by the RF communication device upon occurrence of a predetermined event. The energy received by the RF communication device may be energy transmitted by a shelf or other display unit that an object with the RF communication device is located on. The predetermined event may be any of a wide variety of events. The energy storage may be accomplished in a battery, capacitor, or other energy storage device. The use of energy to enhance communication may be used to provide increased power for sending, receiving, or detecting signals. The enhanced power may be provided continuously, and/or may include periods of power enhancement alternating with periods of non-enhancement.
