5G NR Throughput Estimation - How much speed or data rate will I get on 5G?
This is one of the most popular question that how much will be my speed on 5G. So, this video answers all the calculations and estimations required for 5G throughput calculation in a simple manner. It also shows our 5G Throughput Calculation Tool (5GTCal) as well in order to provide a feel of the 5G throughput and its relation with different factors.

you are the best in 5G among whole youtube tutorials . Thanks a lot . just keep going
Appreciate the kind words :)
You have made the understanding to the calculation so much easier. Thank you. May I know if you will be sharing the same for UL throughput too?
Good idea, let me work on that!
You made is really simple and to the point.
Especially, the overhead part while switching over from DL to UL.
Thank you buddy...
So glad to hear that as this is one of our prime objectives to make things simple!!!
Without even starting video i can bet it would be worth watching and taking notes. No prejudice it's just your article on Initial E-RAB Access in LTE that makes me claim so. Good luck Mr. Ali Khalid
It is great to see such over-whelming response. Thanks a lot, Jawad!
Very helpful....very comprehensive and concise explanation....keep more coming!!!
Thanks a lot :)
This is best video in easiest way … Thanks
Thanks, means a lot :)
Hi, I see there is some typo mistake in first slide.
Instead of mentioning "Maximum bits per symbol" we should write "Maximum bits per slot". Because if we say so "Data carried over 1 RB over 1 slot" would be 132*14*7.4063.
No, 132 is actually already a produce of 12 Subcarriers into 11 symbols. I did not use 14 symbols because of the PDCCH and DMRS overhead.
Max Bits Per Symbol is defined in 3GPP which is 7.4063 for MCS 27 (256QAM MCS Table in 38214)
Thanks Ali for the wonderful video. Question, why you divide on 1024 to call convert from bits to kilo bits and to Mbts. Why not divide by 1000?
Yeah, it is fine to divide with 1000 - you are correct on this point :)
very nice and easy to understand explanation.. thanks
Thanks. This is our objective to simplify complex topics :)
Excellent. Thank you!
You're very welcome!
Can we do UL thrpughput in a similar manner. I mean , i see the diff in MCS part, MIMO Layers & no of UL Slots thats it. isnt it? and can you make a seperate session for UL itself?
Yeah sure. you have listed the main points anyways but I will create one for UpLink too.
Hi Ali! Does DMRS occupy every 4,5 symbols on EVERY subcarrier? Because on some other resoursec I read that DMRS occupu only 4 RE in one RB. Could you please explain that, thanks!
DMRS structure can vary based on implementation. Mostly, even if they occupy 4REs or 6REs, the implementation is such that the DMRS are power boosted so they take away the power the adjacent REs. Thus, in practice, all the SCs in that symbol are un-usable by any other channel. Having said that, there are implementations available where they are not power boosted and thus they can use less number of REs and in that case, the other remaining REs can be used by PDSCH
bless you man!
Thanks
Hi my friend, if we used TDD Pattern 8:2 we would have also every each 1 second 2000 slots ? How the number of DL slot in the same TTI would affect the final formula ? Thank you.
Yes effectively 4:1 or 8:2 turn out to have similar DL/UL slots in 1 second but the number of special slots will reduce with 8:2 as there is only 1 DL to UL switch here in 10 slots.
Hi A query regarding DL/ UL Ratio as it is for TDD what about FDD ?? we will consider all 20000slots for DL ?? in FDD Throughput will be higher with same credentials i.e. (BW, numerology and Massive MIMO).
Yes for FDD, you will consider all slots for DL and then all slots for UL as well. However, usually FDD is in low band which will use 1millisecond slots so there will be 1000 slots. (15khz numerology)
Excellent Explanation!
Thanks Muhammad :)
I guess this throughput is the case of FR1. I also want to know how the throughput is calculated in the case of FR2.
Yes , this is FR1. I will work on FR2 soon as well.
Hello Ali, Thanks for sharing 5G throughput calculation,
i have one query in my mind that , In 5G NR have 8 SSB block(2 SSB per slot) transmitted which took 2ms (carry 20PRBS ) it took 4 symbols in Time domain and repeated every 20ms and PBCH in 80ms. It will not impact our throughput calculation ?
Yeah you are right, this should impact throughput as well. It is part of the throughput calculation in the 5G Throughput Calculator Tool that I showed. However, the impact will be much lesser and can be negligible compared to PDCCH and DMRS.
Firstly, 8 SSB is a vendor specific implementation e.g. Huawei uses 8 SSBs but other vendors might use lesser number of SSBs. So, its overhead is not same and cannot be generalized. Moreover, the impact of 4symbols x 20RBs with 20ms period is pretty low and if we calculate it based on the 100MHz example in the video, it will be less than 1%! Hence, for the sake of simplicity I did not include low overhead channels like SSB, CSI-RS, TRS in the example :)
Please share in building design session. IBWave
Sure, will work on this one soon!
Thanks for all the videos. Please make a video for Wireshark and IRISVIEW and Truecall for coverage and volte call analysis
could u please share 5G calculator . Thanks
Unfortunately, we are unable to share this at the moment. Thanks for understanding :)
Thank you for wonderful video on TPUT, could you pls explain, how we can calculate in the case of FDD?
Then all frames/slots will be used as downlink in the calculation.
@@OurTechPlanet thank you
Thanks Ali. Great brother. You were not well but still doing this video. Very insightful.👏👏
Where can we get the tool you used.,
Thanks Praveen! I will be making a new video to show how to make this tool.
Thanks, good value. Is it possible to download the tool?
Thanks. Not at the moment, still need to perform some tweaks :)
How will 4th Slot 4 DL Symbols (2 GP & 2 UL SRS) throughput value negation be accommodated in the general calculation
In the tool it is done by making a calculation of all available symbols per second for each TDD configuration
Very interesting and this was really well explained.
Thanks, Christi.
Thanks Ali! Really interesting videos!
Thanks Hasan!
Is this training document available?
No, it is only available in this youtube content :)
How did the 3GPP specification figured out the number 20Gb/s throughput for 5G ? Alot of 3GPP documents state the peak date rate for downlink is 20Gb/s. Can you please elaborate on that ?
Will look into it.
I saw that when you change MIMO from 4 to 2, the throughput not reduced to the half. Can you explain this as according to the formula it should be reduced to the half?!
If you do not change anything else but only change MIMO layers from 4 to 2, then yes, the throughput should reduce to half.
Hi Ali, great video. Will it be possible for you to share the throughput calculator tool? Thank you
Thanks Hassan. The tools are still under development as we are adding more features to them. Once completed, we will provide update here :)
@@OurTechPlanet Many thanks. Wishing you the very best with this channel.
@@OurTechPlanet, a tool available now?
@@shatriyan123 Not yet :)
Is the tool available somewhere?
Really interesting
Thanks Abel!
Sir! plz detailed us on 1G & 10G
Currently we only have upto 5G while talks about 6G are going on :)
From where to download this calculator
The calculator is not available , however, I explained how to make one in Python playlists

@@OurTechPlanet okay, noted, thank you
Thank's bro
You are welcome!
Could you share the source code ? Thank you
Not at the moment, there are still some changes that I need to make :)
@@OurTechPlanet Your equation is different from 3GPP spec 38.306 (page 8). Where do you get this equation ?
@@giauhuynh3649 Yes it is different. Mine is a simplification.
