The Ultra High Frequency (UHF) band is the frequency range from 300 MHz to 1 GHz. RFID systems that operate in this frequency band are called Ultra High Frequency (UHF) RFID Systems. UHF RFID tags/readers usually operate at 433 MHz and from 860 to 960 MHz. UHF RFID tags operate using...
By adopting the modular design, the ultra-high frequency RFID read-write module disclosed by the invention respectively realizes and connects all functional modules, and effectively and highly integrates the circuits, so as to greatly simplify the circuit design, reduce the volume of the read-write...
UHF RFID Cards have a good read range and a high data transfer rate. The UHF frequency band covers the range from 300 MHz to 3 GHz. Systems complying with the UHF Gen2 standard for RFID use the 860 to 960 MHz band. UHF RFID has a faster data transfer rate than LF or HF. UHF RFI...
This thesis seeks to address some of these challenges through a new robotic sensing modality that leverages a small amount of environmental augmentation in the form of Ultra High Frequency (UHF) Radio-Frequency Identification (RFID) tags. Previous research has demonstrated the utility of infrastructure...
