4.4 Functions and Operating Modes
The devices can be used to read and write passive UHF storage media in any location. To do
this, the devices form a transmission zone. The size and expansion of this zone may vary on ac-
count of several conditions, for example the tags used and the application conditions. The
devices can only be operated with the Turck RFID app.
4.4.1 Transmission Frequency
The Turck BL ident® UHF system works with country-specific transmission frequencies between
the tags and the read/write heads. These country-specific UHF transmission frequencies are de-
rived from the individual allocation of frequency ranges by the respective national regulatory
bodies.
For example, the operating frequencies of the devices in the UHF band are 865…868 MHz for
Europe and 902…928 MHZ for the USA. Before use, make sure that the BL ident® handhelds
comply with the region's specific UHF band. Any application in regions other than the accred-
ited ones is not permitted. Since BL ident® UHF tags do not emit their own radio waves, they
may be used worldwide.
In order to achieve the biggest possible communication range, Turck offers tags which are op-
timally tuned to country-specific frequency bands. Alternatively, broadband multi-area tags are
also available for international use.
The different Turck handhelds support the following transmission frequencies:
n
865.7…867.5 MHz (Europe)
n 902.75…927.25 MHz (USA, Canada and Mexico)
n
920.25…924.75 MHz (China)
n
920.25…925.75 MHz (Australia)
n
902…907.5 MHz and 915…928 MHz (Brazil)
n
917…920.5 MHz (Korea)
n
916…921 MHz (Russia)
n
920…925 MHz (Singapore)
n
916…928 MHz (Peru)

national regulations are available at:

For more information, please contact the corresponding national authorities of the country in
which you want to deploy the UHF RFID system.
HF RFID systems can be operated in parallel with UHF RFID systems in a single system.
