5G NR ARFCN calculator

This Page provides information about 5G NR ARFCN Calculator. Calculator is based on 3GPP TS 38.104 Release 17 specification.

It will help you to convert the number of the 5G NR ARFCN frequency channel to the 5G NR frequency and back (5G NR frequency to 5G NR ARFCN).

Be Careful, Support ARFCN depends on the frequency band. More information in the tables below.

Example: 5G NR ARFCN = 428000, 5G RF Center Frequency = 2140 MHz

The formula for 5G NR ARFCN is described in 3GPP TS 38.104 chapter 5.4.2.1.

Frequency is selected from 3GPP TS 38.104 Table 5.4.2.1-1

Frequency range (MHz)	ΔFGlobal (kHz)	FREF-Offs (MHz)	NREF-Offs	Range of NREF (NR-ARFCN)
0 – 3000	5	0	0	0 – 599999
3000 – 24250	15	3000	600000	600000 – 2016666
24250 – 100000	60	24250.08	2016667	2016667 – 3279165

By default, frequency range of 5G NR is divide into two parts FR1 and FR2 (below you can see table from 3GPP 38.104, table 5.1-1).

Frequency range designation		Corresponding frequency range
FR1		410 MHz – 7125 MHz
FR2	FR2-1	24250 MHz – 52600 MHz
	FR2-2	52600 MHz – 71000 MHz

Information on the supported FR1 frequencies in table below (3GPP 38.104 table 5.4.2.3-1 ).

5G NR ARFCN Calculator
Enter the Frequency, MHz*

doesn’t accept but whole num… ex if you attempt to enter 644.5 will not accept

  FREF = FREF-Offs + ΔFGlobal (NREF – NREF-Offs) (i)
  NREF = NREF-Offs + (FREF – FREF-Offs) / ΔFGlobal

  Is there a fixed number of nrarfcn in 5g Or 4g.even in 2g it was not fixed. I was asked this question in ericsson interview. As per my understanding there are more than 100 different frequency bands and each has got different range and deltafglobal value. Hoe can there be a fixed number say for 5g.

Do you have something that allows me to calculate the channels needed from start ARFCN to last ARFCN and creates a test channel list based on step. For example start, stop, step based on channel bandwidth ?

Great tool but has some minor precision issues. Your precision is limited with 2 digits for output of ARFCN to frequency conversion. For example, If use the ARFCN 399967 your tool produce 1999.84 MHz but actual value ise 1999.835 MHz. It would be better to use 3 digits for MHz.

Do you have the formula to calculate the 5G ARFCN from the 4G ARFCN?

  This is invalid request as you could get the 5G physical frequency from 5G ARFCN and then convert 5G physical frequency back to EARFCN…

why in freq range 24250 – 100000，the FREF-Offs is 24250.08 instead of 24250?
