What interference can affect RFID?
Interference source
Cause
Remedy
Switched-mode power supply Interference emitted from the
current infeed
Replace the power supply
Cable is inadequately
shielded
Better cable shielding
Interference injected through
the cables connected in
series
The reader is not connected
to ground.
Ground the reader
caused by another reader
•
Change the operating mode of the
reader.
•
Position the antennas further
apart.
•
Erect suitable damping materials
between the antennas.
•
Reduce the power of the readers.
HF interference over the
antennas
External sources of
interference that use or
transmit on the same
frequency range.
Use the frequency hopping technique
