Radio Frequency Identification (RFID) is a rapidly expanding technology with new
applications emerging at a remarkable rate. From management of warehouse inventory
to identification of patients in a medical setting, proper deployment and unimpeded
communication between RFID readers and tags is paramount to successful
operation.
One of the major considerations when implementing an RFID system is
the effect of unwanted RF interference between Readers and Tags. Most
workplaces have hundreds if not thousands of electronic devices that
create unwanted interference, including computers, Bluetooth networks,
wireless networks, motors, conveyors and robots. Actually, any device with
a microchip and power cord or cable will emit RF energy which can interfere
with the ability of the reader to receive a clean signal.
Leader Tech offers a simple “first-step” approach to reducing unwanted RF interference.
We recommend the following:
Identify Sources of RFID Interferences
The FerriShield CTK031 hand-held probe (see below) is one of the easiest ways to identify unwanted
electro-magnetic interference. All you need to do is pass the probe over suspect sources. If the device
detects RF emissions it alerts with an audible tone that intensifies as interference increases.
Attach a Frequency-Specific RFID Ferrite to the Suspect Device
3-Steps to Reducing RFID Interference
Samplings of our most popular RFID ferrites are shown on the following page. In addition, a free 32-piece
engineering kit is provided with the purchase of any CTK031 Probe.
Check If Interference Has Been Eliminated
After you have attached the cable-mounted ferrite, simply use the hand-held RF probe to confirm that the
ferrite has eliminated the unwanted interference.
