Rf Profiles - Nordic ID SAMPO S2 User Manual

1.11. RF PROFILES

This section applies only to Nordic ID Sampo S2 One-series reader. 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
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 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
Nominal RF-profile is the default setting of readers containing Nordic ID NUR2-1W UHF
o
RFID module. It uses link frequency of 300 kHz and Miller 2 coding providing read rates
up to 350 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 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.
NOTE! Read rates will depend from the environment, reader settings, tag population and tag type.
1.12. ANTENNA CHARACTERISTICS
Nordic ID Sampo S2 reader includes an internal wideband circularly polarized UHF RFID antenna.
Nominal reading distances are:
•
Nordic ID Sampo S2 in normal mode: 5 m / 16 ft
•
Nordic ID Sampo S2 in low-gain mode: 1.5 m / 5 ft
•
Nordic ID Sampo S2 One-series: 10 m / 33 ft
NOTE! The reading range depends on used tag and environment
USING EXTERNAL ANTENNAS WITH NORDIC ID SAMPO S2
Sometimes there can be challenging areas in the reading environment that needs extra coverage. For this
purpose, there are 3 SMA female connectors (AUX1, AUX2 & AUX3) in the Nordic ID Sampo S2 reader.
The external antennas can be enabled/disabled via SW and be used to improve reading performance and
accuracy if needed.
1.13. THERMAL MANAGEMENT
Nordic ID Sampo S2 reader includes sophisticated thermal management features that do prevent
overheating issues if reader is used in too warm environments. The reader monitors temperatures of
