This page provides the equations for converting between frequency and UARFCN. It also includes a link to an online calculator for convenience.

UARFCN stands for UTRA Absolute Radio Frequency Channel Number. It’s primarily used in UMTS/WCDMA systems to convert frequencies in different bands to a UARFCN number, and vice versa.

Frequency to UARFCN Conversion Equation

  • UARFCN in the downlink = 5 * (Downlink Frequency - FDL_Offset)
  • UARFCN in the uplink = 5 * (Uplink Frequency - FUL_Offset)

UARFCN to Frequency Conversion Equation

  • Downlink Frequency = FDL_Offset + 0.2 * (Downlink UARFCN)
  • Uplink Frequency = FUL_Offset + 0.2 * (Uplink UARFCN)
