4G LTE Throughput calculator

This Page provides information about 4G LTE Throughput calculator. Calculator is based on 3GPP communication standards and allows you to calculate the maximum throughput of 4G LTE networks.

To obtain the correct result, it is necessary to enter such important parameters as: mode of 4G LTE network, number of aggregated carriers, number of MIMO layers, Bandwidth, modulation type, and so on.

Update1: ADD special subframe configuration for TDD MODE

Update2: ADD Code rate parameter for more accuracy calculation

Update 3: ADD Auto-calculation for Overhead control channels

  • VERY USEFUL

  • May I know what is the default stetting for Special subframe configuration?

    • Dear, Max!
      Default was 9.
      But Now We Add parameter for special subframe configuration [0-9] for TDD Mode. You can use it.
      Regards

      • Hi Oleg,

        I tried to select special subframe configuration to 0 and 5 which were calculated results different from yours. When I selected conditions as below:

        – Test Direction = Downlink
        – CA = 1
        – Modulation = 64QAM = 6
        – MIMO Layer = 2
        – RB = 100
        – Factor = 0.75
        – TDD configuration = 0 (DL = 2, SSF = 2)
        – Special subframe configuration = 0 (Dw = 3)
        PS: Normal CP = 14 OFDM symbols per subframe

        So my formula is
        Throughput = (((((14 * DL) + (Dw * SSF)) * Modulation) / 10) * 12 * RB * MIMO Layer * CA * Factor)/1000
        Throughput = (((((14 * 2) + (3 * 2)) * 6) / 10) * 12 * 100 * 2 * 1 * 0.75)/1000 = 36.72 Mbps

        But I used your website to calculate the result equal 30 Mbps. In addition to special subframe configuration 0 and 5, the others results are correct. Could you give me suggestion if I was wrong?

        Thanks for your help.

        • Dear, Max!
          I checked 3gpp 36.211 Table 4.2-1 again and find some mistakes at my formula (wrong number of DwPTS symbols at DL for 0 and 5 SSF). Fixed it. Please check! Thanks to you! 🙂
          Regards,
          Oleg

  • Hi Oleg,

    Thanks for your information and feedback.
    It’s correct result now. 🙂

  • Hello Oleg,

    why i get lower DL NR throughput on 20MHz /15khz vs LTE 20MHz, FDD . result is 128mbps NR vs 151 Mbps LTE?
    same parameters used where available in the tool.

    • Dear, Nik!
      Can you sent me parameters, that you used for NR.
      Because i got:
      LTE: DL,FDD,1carriers, MIMO 2×2,64QAM, BW:20 MHz (100 PRB),0.75 => 4G LTE Throughput = 151 Mbps
      NR: Dl,FDD,1carriers, MIMO 2×2,64QAM,Scaling factor:1,BW:20MHz FR1 µ:15kHz (106 PRB),Rmax=0.92578 => 5G NR Throughput =170 Mbps (not 128)
      170/151 = 1.13 or 13% better for NR
      Regards,
      Oleg V

  • Hello Oleg,
    same parameters as your example, except for scaling factor which was 0.75 for both NR and LTE. I see you used 1 for NR – is there a reason to have different?
    thx, Nik

    • Dear, Nik
      “Scaling factor parameter at NR” it is not same like “Factor taken into account the control information” at LTE
      At 5G we use “OH(j) -overhead for control channels” like “Factor taken into account the control information” at LTE
      Scaling factor parameter at NR – part of carrier that can be used for transmission (for Max Rate should be 1)
      Regards,
      Oleg V

  • Hi Oleg,
    thanks for explaining.
    Best regards,
    Nik

  • Can you please add the option to check throughput values for various CFI values.

  • Hi,

    Useful tool. Can you also add an option to input Bandwidth of Component carriers for more accurate estimisation.
    Thanks.

  • very good tool thanks
