RFID Frequency Bands

There are several frequency bands allocated to RFID operations. In general, high frequencies permit greater data transmission rates, which is a major factor that influences the time it takes to actually read an ID-tag. Which frequency that is used therefore impacts at which speed a vehicle may be moving while the ID-tag is being identified. High frequencies also give a better defined coverage area (radio lobe).

Low frequency RFID systems (<100 MHz) typically work by induction between the Reader and the ID-tag and is therefore generally used at short ranges.
