UMTS/WCDMA UARFCN to Frequency Conversion

This tutorial section on UMTS basics covers following sub topics:
Main Page  Architecture  Stack  channel types  Bands  UARFCN  Frame  Timers 

The page provides frequency to UARFCN and vice versa conversion equation. It provides link to online calculator for the same.

UARFCN stands for UTRA Absolute Radio Frequency Channel Number mainly used for UMTS/WCDMA system to convert frequency in different bands to 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)
