What frequencies are used for RFID?
Radio signals are used by a wide variety of technology, from cell phones to television. To prevent wireless technologies from conflicting with each other, different technologies are assigned to different radio frequency bands. For example, AM stations broadcast around 1 MHz and FM stations broadcast around 100 MHz. RFID has also been assigned several specific bands, but this varies around the world. A few common frequencies include: • 13.56 Mhz -> High Frequency (HF) band used worldwide for passive RFID tags such as in keyless entry cards. • 433 Mhz -> Ultra-High Frequency (UHF) band used by many active tags. • 902 – 928 MHz -> Ultra-High Frequency (UHF) band used by passive EPC Gen 2 RFID readers in the US. • 865 – 868 MHz -> Ultra-High Frequency (UHF) band used by European passive EPC Gen 2 RFID readers. • 2.4 GHz -> WIFI frequency band used by certain US active tags. ODIN has experience with RFID technologies across all of these bands, in fact, our lab has been certified by the FCC
