RF PROFILES

Nordic ID NUR3-1W 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 (max sensitivity)
Robust RF profile is intended to be used in challenging environments. It provides the best
o
filtering against the interfering signals coming from nearby reader(s), other signal sources
and from reflective environment. This profile uses link frequency of 160 kHz and Miller
8 coding scheme providing read rates up to 100 tags/s. Due to the low data speed and
best filtering the Robust RF profile provides the best sensitivity.
• Nominal
Nominal RF-profile is the default setting of readers containing Nordic ID NUR3-1W UHF
o
RFID module, such as Nordic ID FR22. It uses link frequency of 300 kHz and Miller 4
coding providing read rates up to 300 tags/s.
• High speed
High speed RF profile is intended to be used in use cases where the highest read rates
o
are required. It uses link frequency of 640 kHz and FM0 coding and provides read rates
up to 1000 tags/s. Due to the high data speed this profile is quite sensitive to
interferences.
NOTE! Read rates will depend on the environment, reader settings, tag population and tag type.
