摘要

Systems and methods for operating a Radio Frequency Identification (“RFID”) tag. The methods comprise: monitoring a level of Radio Frequency (“RF”) energy being received by the RFID tag; performing operations by a circuit of the RFID tag to compare the level of RF energy in a given frequency band to a first threshold value; and transitioning an operational mode of the RFID tag from a first operational mode in which a receiver is disabled to a second operational mode in which the receiver is enabled, when the level of RF energy exceeds the first threshold value. The RFID tag is able to communicate with a remote tag reader when the RFID tag is in the second operational mode and not when the RFID tag is in the first operational mode.

說明書

In some scenarios, the communication enabled device 204 comprises a Software Defined Radio (“SDR”). SDRs are well known in the art, and therefore will not be described in detail herein. However, it should be noted that the SDR can be programmatically assigned any communication protocol that is chosen by a user (e.g., RFID, WiFi, LiFi, Bluetooth, BLE, Nest, ZWave, Zigbee, etc.). The communication protocols are part of the device's firmware and reside in memory 208. Notably, the communication protocols can be downloaded to the device at any given time. The initial/default role (being an RFID, WiFi, LiFi, etc. tag) can be assigned at the deployment thereof. If the user desires to use another protocol at a later time, the user can remotely change the communication protocol of the deployed tag 200. The update of the firmware, in case of issues, can also be performed remotely.

As shown in FIG. 2, the communication enabled device 204 comprises at least one antenna 202, 216 for allowing data to be exchanged with the external device via a wireless communication technology (e.g., an RFID technology, an NFC technology and/or a SRC technology). The antenna 202, 216 is configured to receive signals from the external device and/or transmit signals generated by the communication enabled device 204. The antenna 202, 216 can comprise a near-field or far-field antenna. The antennas include, but are not limited to, a chip antenna or a loop antenna.
