5G GSCN Calculator

Updated R17.30 (2021-10-01)

Enter your Global SCN below to translate it into the SSRef in MHz and nearest ARFCN.

GSCN to SSRef/NARFCN

Enter your SSRef frequency below to convert the nearest GSCN and ARFCN. Note that it is possible that exact frequency does not have a matching Integer GSCN in which case this is unsuitable SSRef for the case of 5G SA.

SSRef to GSCN/NARFCN

Enter your ARFCN frequency below to convert to nearest GSCN and SSRef. Note that it is possible that exact ARFCN does not have a matching Integer GSCN in which case this is unsuitable SSRef for the case of 5G SA.

NARFCN to GSCN/SSREF
Explanation

The first button translates a GSCN into the frequency domain position of the SSB block.
The second translates a SSREF number to frequency. You also see a reverse translation of the closest integer frequency into a valid GSCN.
