RF PROFILES
Nordic ID NUR2-1W UHF RFID module supports three different kind of RF profiles. The profiles are
Robust, Nominal and High speed. It’s important to select the correct RF profile based on use case and
environment. More detailed description about the RF profiles can be found below:
•
Robust
o
Robust RF profile is intended to be used in challenging environments. It provides the best
filtering against the interfering signals coming from nearby reader(s), other signal sources
and from reflective environment. This profile uses link frequency of 250 kHz and Miller
4 coding scheme providing read rates up to 200 tags/s. Due to the low data speed and
best filtering the Robust RF profile provides the best sensitivity.
•
Nominal
o
Nominal RF-profile is the default setting of readers containing Nordic ID NUR2-1W UHF
RFID module. It uses link frequency of 300 kHz and Miller 2 coding providing read rates
up to 350 tags/s.
•
High speed
o
High speed RF profile is intended to be used in use cases where the highest read rates
are required. It uses link frequency of 400 kHz and FM0 coding and provides read rates
up to 1000 tags/s. Due to the high data speed the profile is quite sensitive to
interferences.

THERMAL MANAGEMENT
Nordic ID AR82 reader includes sophisticated thermal management features that do prevent overheating
issues if reader is used in too warm environments. The reader monitors temperatures of onboard
computer and UHF RFID module and adjusts operation points based on the temperature information.
Onboard computer starts mitigation scheme (for example clock frequencies of CPUs are dropped) when
temperature of the onboard computer reaches 85°C.
NOTE!
If reset button is pressed over 5s after the CONNECTION LED has turned on and the red
INDICATION LED has started blinking even faster, releasing the reset button will perform a
normal reboot.
NOTE!
Read rates will depend from the environment, reader settings, tag population and tag type.
