Abstract: Described herein are methods, devices and systems for characterizing an attached antenna to an electronic device, such as a radio frequency identification ("RFID") reader. One exemplary embodiment is related to a method comprising outputting a low amplitude modulation ("AM") index radio frequency ("RF") waveform, the waveform simulating tag data timing and bandwidth, removing a direct current ("DC") component from the waveform to create a chopped portion of the waveform, applying at least one vector analyzer technique on the chopped portion of the waveform, characterizing at least one antenna impedance vector of the waveform.

Abstract: Updating a multi-band reconfigurable electronic shelf label includes waking-up a transceiver and processor of the electronic shelf label, such that the transceiver can be reconfigured to operate on a selected frequency band in order to receive updated information on a data link associated with that selected frequency band. The selected frequency band is chosen based on a power efficiency of the associated data link. The updated information can be received on the associated data link of the selected frequency band, and can be displayed on a display of the electronic shelf label. A supplemental data link using a Radio Frequency Identification circuit can be provided among the other data link selections in the label.
