4.2. Assessment and deployment of RFID technology
In order to facilitate receiving and shipping process in the CDC
and LDC, long RFID reading range of up to several meters is required.
UHF RFID equipment operating between 922 MHz and
928 MHz ranges is adopted in this study, including fixed reader,
handy reader, and passive tag. Fixed RFID reader and antennas
are installed at receiving and shipping door, where two antennas
are installed at each side of the door, 3 m in distance facing each
other, and 3.45 m for lateral distance.
