  • 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

      Regards

  • 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
