4G LTE EARFCN calculator

This Page provides information about 4G LTE EARFCN Calculator. Calculator is based on 3GPP TS 36.101 Release 17 specification.

It will help you to convert the number of the 4G LTE EARFCN frequency channel to the 4G LTE frequency

The formula for 4G LTE EARFCN is described in 3GPP TS 36.101 chapter 5.7.3.

  • 36.101: 5.7.3 Carrier frequency and EARFCN

    The relation between EARFCN and the carrier frequency in MHz for the downlink is given by the following equation, where FDL_low and NOffs-DL are given in Table 5.7.3-1 and NDL is the downlink EARFCN.
    FDL = FDL_low + 0.1(NDL – NOffs-DL)
    The relation between EARFCN and the carrier frequency in MHz for the uplink is given by the following equation where FUL_low and NOffs-UL are given in Table 5.7.3-1 and NUL is the uplink EARFCN.
    FUL = FUL_low + 0.1(NUL – NOffs-UL)

    But you calculation only use the NDL to calculation FDL and FUL.
    Can you tell me the reason?

    I mean that the two equations is independent.

    • Dear, Maxwell

      If you check 3gpp 36.101 table 5.7.3-1 (page 126)
      You can see that NOffs-DL and NOffs-UL is dependent. (it’s not obvious at all)
      For Band 1-28: NOffs-UL = NOffs-DL+18000
      For Band 30-31: NOffs-UL = NOffs-DL+17890
      For Band 33-52: NOffs-UL = NOffs-DL
      For Band 65-66,70-74: NOffs-UL = NOffs-DL+65536
      For Band 68: NOffs-UL = NOffs-DL+65136
      For Band 85: NOffs-UL = NOffs-DL+65636
      ….

      If you know EARFCN DL then you know EARFCN UL…
      then you know frequency

  • Great tool. I’m an RF Engineer myself so I find this very useful. Thanks for your hardwork.

  • What if the result in frequency DL is785.5 , the the frequency in modem didn’t accept the number with (.) Dot

    • Dear, Mart!
      If you use for example:
      Band 28 EARFCN DL = 9485, You will get DL Fr: 785.5 UL Fr: 730.5
      It is OK (3GPP TS 36.101 Release 15 specification)
      I dont uderstand, what is wrong with (.) Dot?
      Regards, Oleg

  • Dear Oleg,

    Could you provide the inverse calculation, where we can enter the downlink frequency and get the EARFCN.
    This would help checking some results.

    Thanks

  • Can this be modified for the Moon for LTE and 5G?

  • In our network there is a plan to implement TDD with 3 Carriers of 20MHz/20MHz/10MHz respectively. How we can choose the EARFCN using frequency range between 2550-2600MHz, with respecting the guard band in both sided?
