RFID Tags |
Tags type | Active and passive tags |
Battery life | Active tags 1-5 years (depending upon the data transmitted frequency) and passive tags requires no battery (Mogre, 2009) |
Tag read range | For active tags 1-500 feet (depending upon readers sensitivity settings) and for passive tags 1-20 feet read range |
Life cycle | Active tags up to 5-10 years and passive tags up to 20 years |
Tags Frequencies | Microwave, Ultra High, High and Low frequency (Ostbye et al., 2003) |
Microwave frequency | Works on 2.5 GHz with maximum 5 feet reading range |
Ultra High frequency | Works on 860-930 MHz and has maximum 20 feet reading range |
High frequency | Works on 13.56 MHz, used for short reading range applications and has less than 3 feet reading range |
Low frequency | Works on 125 KHz, used for short reading range applications and has maximum 2 feet reading range |
Storage Capacity | 1 byte – 10 Mbytes |
Wake up frequency | 1-500 MHz |
Tags classification | Class 0, Class 1, Class 2, Class 3 and Class 4 (Massuod & Hassan, 2012) |
Class 0 | Read only, id number is written only once during manufacture |
Class 1 | Write Once Read Many, data can be written by manufacturer or the user one time |
Class 2 | Read-Write, user can access read and write operation into the tags memory |
Class 3 | Read-Write with sensors, records parameters like motion, pressure and temperature |
Class 4 | Read-write with integrated transmitter, communicates with other tags without the presence of readers |
RFID Field Generator |
Functionality | Produce 1-500 MHz field to wake-up active tags |
Tags wake-up range | 10-200 feet (depending upon field generator strength) |
Flexible strength setting | Allow adjustment of wake-up tag range |
Provides cost effective tracking system | Cost lower than RFID reader |
Optional | Motion detection |
RFID Antennas |
Functionality | Used as a medium for tag reading |
Antennas types | Omni directional, dipole or multi pole, patch, linear polarized, circular polarized, stick, beam-forming or phased-array elements, Gate and adaptive antennas (Ahsan et al., 2010) |
Operating Temperature | -30 °C-70 °C |
