Very informative, would be even more attractive if you used a real human voice (or a better voice) for the explanation rather than system voice which is monotonous to hear. But great animations and breakdown of concepts.
+Vishal Vudayagiri - Hi Vishal. Thanks for your valuable feedback. We tried using real voice. But due to lack of proper studio type environment and our accent, that idea had to be scrapped. Using two voices and a soothing background music were the only logical option we had; to break the monotony. Maybe in future we will use real voice. Till then bear with us. Happy learning.
I'd love to help you with that for no cost. I'm into voice acting, and also am graduating in Telecommunications Engineering, having worked with Mobile Networks. viniciuscunha013@gmail.com Reach me out !
LTE .I like the voice ..used system voice is great..love to hear it...real voice has too many breaks and eventually makes u loose attention..and interest
The best method and presentation for Multiple Access technologies.Excellent job.Very informative and reliable for telecom Engineers specially beginners
This is an excellent telecom video tutorial, the best i have ever seen. Great job! The presenters should be given an award and they deserve a Nobel Prize.
Bonjour ce cours est super bon même si j'ai eu du mal comprendre l'anglais mais les illustrations sont trop cool merci infiniment et j'espère le revoir en français si possible
+Tarandeep Kalra - wait for a few more days. I assure you, it will be worth the wait. In the meantime you can watch the other videos and share your opinion. Happy Learning.
This is ACTUALLY a summary video. Our main target is LTE but we thought without discussing Multiple Access techniques we cannot explain OFDMA. We are glad that you liked the video. Happy Learning :)
+Ne May - This video was uploaded in August and yes we were using text to speech converter back then. Watch our last 2 videos on CA and HetNet. We have used human voice. Do share your feedback with us. Happy Learning
1:15 Since separate nodes are transmitting at different frequencies, they wouldn't be detected as one smooth wave as you show. It would be detected as multiple simultaneous waves at different frequencies.
Yet now i cannot understand how FDMA, TDMA, CDMA, WCDA really works. How these phenomenons are physically used? I dont believe they exist. If you can make a video on it, I'll appreciate.
Very well explained.Thank you. Can you please share the references used in making this videos(for eg: technical papers) other than the one mentioned above.
+Freebirds 360 - we have tried to maintain a tempo so that people don't get bored. We will try to slow it down in our next video. You can try pausing and replaying if you are finding it difficult to follow.
+meLLoxo as far as military use is concerned, both TDMA and FDMA are inferior to CDMA which was specifically designed for this purpose because of its spread spectrum nature and later gained widespread use in the public telecommunication domain.
Hi great video my name is David Adams I am the legal patent owner of 10 global patents my late father Andrew Brian Johnson invented the GSM 202 204 206 base station digital data transciever in 1989 whilst working for telecom Australia. He was under contract with Telstra as co-investors from 21/9/1993-21/9/2001 then he became soul owner of said inventor patent. 1 month later he died. In the same month 3G was released.24/10/2001. Then for 15 years Telstra have stolen sold and robbed my fathers legacy from his grave.. As I had no knowledge of my fathers achievements until I google searched him late last year. I'm still trying too understand a lot about the wireless packet concept as it's quite complex
Thanks Divya. We will keep your concern in mind. You can always pause if you are facing difficulty in understanding. If you want we can share the trnscript with you. Happy Learning
very good video. however I need CDMA in details (I mean with mathematical examples). can you provide some trusted link for that? or can you make video for that?
+Ravi Raushan Kumar, we are considering a series on aspects of LTE only, so CDMA is out of our scope.. to get good information on CDMA, you can follow NPTEL series on SS and CDMA at nptel.ac.in/courses/117104099/13.
Can we get more such videos on LTE..RACH,CELL SEARCH PROCEDURE AND MEASUREMENTS...Would also like to be a part of this do let me know if I could be of any help in making these videos
Very informative, would be even more attractive if you used a real human voice (or a better voice) for the explanation rather than system voice which is monotonous to hear. But great animations and breakdown of concepts you should add sdma
+Huda Anwer, sorry to tell you but plotting of BER vs SNR is something we have not covered in our video series and is neither in our future options... Btw you can check MATLAB threads on this topic: in.mathworks.com/matlabcentral/newsreader/view_ thread/41353

Fantastic set of videos, your new one using human voice is much more pleasant. Thanks for the great work
+Never fart on a man's balls - Thanks. Personally we will feel better if you could change your name.
This is an excellent telecom video tutorial, the best i have ever seen. Great job! The presenters should be given an award and they deserve a Nobel Prize.
+wci kansas lol! Thanx for the nice words. But Nobel Prize is a little extreme. :P
Aw man! You broke our heart. We had our backpacks ready for a trip to Sweden.
Nobel prize is extreme af ahhahaha
It's easy to understand, I've shared those video to my friends. Thanks those video makers.
thanks Benle for your support. It means a lot.
Thanks for explaining the evolution of communication .....
Pretty decent description of wireless tech.

My pleasure LTE
For some weird reason I find this text-to-speech voice quite suitable for this video series.. D: / :D
Great job thank you alot..... You should be given an award
Thanks Jawad. We are just trying to spread knowledge.
Easy to understand such a big concept in a easy way..with gud presentation..
Thanks Sonu
it is good videos
best video on youtube. Thanks a lot

Happy Learning.
I already have seen all the other ones :-).Seeing these videos reignited my interest in learning LTE.
+Tarandeep Kalra- lol. Thanks Tarandeep. We are trying our best to complete our next video as fast as possible.
This was like a summary video. Should have to be more longer. By the way nicely explained.
This is ACTUALLY a summary video. Our main target is LTE but we thought without discussing Multiple Access techniques we cannot explain OFDMA. We are glad that you liked the video.
Happy Learning :)
Fantastic explanation.
thanks for the video
the electronic voices are a bit monotonous, but still the content is great
keep it up
+MrBitviper - Thanks for understanding. What do you think of our latest videos which contains human voice?
Visual concept are awesome. Imo please consider audio effects and tempo, for me it's little bit unnatural. Anyway great job and waiting for more.
+Forein Tes - the audio effects are loud and the videos move fast. Is that what you mean to say?
Awesome Simple video. Thanks for effort.
+Gyan Deep - Thanks a lot. We try our best to spread deep gyan. :)
Don't worry . I am spreading it too. That's minimum I can do.
+Gyan Deep - Thanks a lot for your help.
Happy learning
Not the robot voice again !!! DAMN iT !

GREAT VIDEO!
VERY MONOTONE!
Yet now i cannot understand how FDMA, TDMA, CDMA, WCDA really works.
How these phenomenons are physically used? I dont believe they exist.
If you can make a video on it, I'll appreciate.
What don't you understand? Maybe I can help.
If WDMA is based on color, then that's equivalent to FDMA. Color is frequency.
LONG TERMINAL EVOLUTION
Very well explained.Thank you. Can you please share the references used in making this videos(for eg: technical papers) other than the one mentioned above.
+Mahesh Kalkundri - We didn't use any technical papers. The video covers only the basics. So the sources mentioned in the description were sufficient.
ok fine :)
thank! It is easy to understand
I like all your videos but all those are fast. could you be please bit slower?
+Freebirds 360 - we have tried to maintain a tempo so that people don't get bored. We will try to slow it down in our next video. You can try pausing and replaying if you are finding it difficult to follow.
you can literally slow the video down under the speed option.
Nice lecture ... #HariKrishnaSahu
nice explanation
+MUHAMED AZAHIR Thnks. Don't forget to share it with your friends.
yaaah sure
it helps to my exam
جميل لانه مترجم للعربية... شكراً
thank you very much for this video
Actually, the video is only 6 minutes but I take 2 hours to re-watch and understand what is modulation used in CDMA, like LDPC code or Turbo codes
Thank you!
from a tactical perspective (military) what are the pros and cons of FDMA v TDMA ?
+meLLoxo as far as military use is concerned, both TDMA and FDMA are inferior to CDMA which was specifically designed for this purpose because of its spread spectrum nature and later gained widespread use in the public telecommunication domain.
Romba speed a poreenga.but super explanation.konjam speed a reduce pannikonga
Great Job...
Thanks Vignesh
Slow it down guys, too fast. Takes away from the very good explanation..
Like the voice👍
very use full
+GPraveen Kumar - Thanks buddy
Thanks! great video, but sounds like i'm listening to Rosie the Robot Maid from the Jettsons...
Thanks for ur information

Really sad to hear that. Is there any way we can help you?
Great animation. It is very easy to understand. But the female system voice is hard to hear.
nice making very interested
Love this alot
+Agung Kesava - Happy Learning mate
grt work,easy to understand but some time little bit fast
+Dushyant Arya - Thanks man. We will try to keep the tempo low in our upcoming videos. You can try pausing the video when you face problem.
With the text to voices I feel like I am gonna get arrested for watching this.
Better than hindi
Good because it translate into Arabic.... Thanks
Is it possible to get the content that you have used for the video in the form of document/notes?It would be really helpful.
Explained well but slow it down all the videos are very fast Thanku!
Thanks Divya. We will keep your concern in mind. You can always pause if you are facing difficulty in understanding. If you want we can share the trnscript with you.
Happy Learning
is there such thing called FTDMA ??
What program you use for creating these presentations? They are really nice
+Lukasz Stanek - Trade secret. Can't reveal. ;)
Great job, does anyone know what they are using to make these drawings please ?
very good video. however I need CDMA in details (I mean with mathematical examples). can you provide some trusted link for that? or can you make video for that?

Thanks very informative
+Apratim Sinha thank you...stay tuned for upcoming videos..
Great
Very informative, would be even more attractive if you used a real human voice (or a better voice) for the explanation rather than system voice which is monotonous to hear. But great animations and breakdown of concepts
you should add sdma
great !!
+Nachiket Ayir thanks for appreciation...stay tune for future videos..
HI LTE,
Thanks for the information through videos.
Can you share the information, How do you make these video and animation?
Thanks
Hello Arif,
We use VideoScribe for animation and Adobe audition for sound processing.
Thank you
Hi,
Can we provide 100% overlap coverage, using 5MHz bandwidth in 700 MHz spectrum in LTE?
My phone provider support CDMA . Will WCDMA work with my provider ?
Wcdma is umts/hspa+ so no
which software use
Good visualisation , just use better human voice as it doesn’t feel connected to the voice and takes time to understand what does it exactly mean.
We can understand. That's why we migrated to human voice in the latest videos.
Happy Learning
useful
What is the name of your organization
mam please explain slowly
+Sandip Avere - you can pause and replay.
you can literally slow it down to .75 under the speed option.
Fui obrigado a ver.
Every one is here just becoz of 7 lakh veiws😂
Good job, I understand that thanks to you Can I get a lot of information and how to run this technique should SOFTWIRE such as Riverbed plzzzzzzzz ":9
+Abeer Ben - Hello! We couldn't understand your question.
okay , am sorry but i mean
"simulation"
How can OFDMA technology application
? Software such as the Riverbed
+Abeer Ben we are extremely sorry. We haven't used that tool. Can you tell us few things about it?
hi, pls i need help in plotting BER ves SNR in matlab can you help
+Huda Anwer, sorry to tell you but plotting of BER vs SNR is something we have not covered in our video series and is neither in our future options... Btw you can check MATLAB threads on this topic: in.mathworks.com/matlabcentral/newsreader/view_ thread/41353
