# 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

Update 4: ADD CQI (MCS) option for user configure

Update 5: ADD button to export result

VERY USEFUL

• HB chen

good tool

• Max

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

• OlegV@5GTools

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

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! 🙂

Can any one tell me the simplest formula for dl throughput

• Max

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.

• OlegV@5GTools

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

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

• OlegV@5GTools

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)

Hi Oleg,
thanks for explaining.
Best regards,

• Sumesh

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

• OlegV@5GTools

Dear, Sumesh!
I did it, Auto-calculation for Overhead control channels
Please check.

• Naveen

Hi,

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

• Niyaz Adil

very good tool thanks

• Max

Hi Oleg,

Is it possible the tools can add MCS option for user configure?

As I saw the throughput always uses the maximum MCS to calculate…right?

• OlegV@5GTools

Dear, Max!
i did it! Add CQI (MCS) table from 3gpp 36.213
Regards, Oleg V.

• Bhanu

what is the overhead considered for UL throughput calculations and what this overhead consists of? any 3GPP reference

• Sap

Hi Oleg,

Modulation and Code Rate inputs for 4G TDD/FDD UL throughput calculations.

Ch. 7 in the 36.213 has to do with DL PHY channels. Thus, the referenced CQI tables would not apply for UL transmissions. If you agree would it be possible to review the algo and include Ch. 8 (UL PHY) references instead. I’m a bit skeptical that the UL throughput rates are calculated correctly.

• Eric

Hello Oleg,

Can you kindly advise what the condition is to calculate the LTE category 18 UL data rate of 316Mbps?

Regards,
Eric

• Eric

sorry, it should be UL category 20.

• Rafael Viegas

Dears,

thank you for this tool. very helpful

But I think UL calculation is not right, it is resulting in the same values of DL.

Could you check?

• Namanya osbert

Hello guys, this is helpful

But how can i calculate user latency in a hetNet made of lte-nr configuration

• Loreno Menezes da Silveira

Hi, the calculator applies to which Release(s) or version of LTE specifications?
