Abstract
A system for cost-effective and accurate reading of RFID tags. The system includes an RFID reader and one or more booster modules connected to the RFID reader. Each booster module has its own power supply, allowing for an amplification of a portion of the RFID signal that is output by the RFID reader. Thereby, the total power output of the system can be increased, and a read range and read accuracy can be improved due to additional antennas provided in the booster modules. In addition, it also becomes possible to reduce the power output by the RFID reader in order to increase the read accuracy of the same.
Claims19
A system for reading Radio Frequency Identification (RFID) tags, the system comprising:
- an RFID reader configured to output an RFID signal;
- at least one booster module configured to receive the RFID signal;
- and
- a system controller configured to output a control signal for the at least one booster module;
- wherein each booster module of the at least one booster module comprises:
- a module controller configured to receive the control signal;
- a power amplifier configured to amplify at least a reduced power portion of the received RFID signal to generate an amplified RFID signal;
- and
- at least one booster antenna configured to emit the amplified RFID signal.
