Content on this channel is really good. Stop worrying about voice (human/robotic). Content is good most importantly and voice is good enough to understand . Thanks .
+Thunder 440v - Thanks a lot for the nice words. It's people like you who motivate us to work hard. We will definitely keep making videos as long as we can. Happy Learning.
The highest rated comment here said the same thing. Anyway, it’s your channel and you can share however you like! I really appreciate the information any way you do it!
+Alan Spicer - lol! Sometimes we feel that we should increase our our frequency of video upload. You make us realize that it's okay to be slow. We always appreciate your support. Happy learning
Great job people, this kind of stuff is really making things easier to understand for beginners.Can you make such effort covering the LTE stack? Thanks in advance :)
I really appreciated you using your natural voice! i find it a lot easier to understand than the synthetic ones. your accent is quiet present, but it is good to understand! :)
Great video! One question: does CA only work well at cell edge? at 2:30 the graph shows a phone communicating with several different cell towers (each cell tower is a eNB right?). I thought CA is about one serving basestation capable of handling multiple carrier components
Thanks Steven. Glad that you asked we also had similar confusion. The answer is No! CA can be implemented anywhere. It can be implemented inside a single cell or inside overlapping cells(where small cells are involved). At cell edge where the performance degrades CA can be used to enhance it. In co-ordinated Multipoint (shall be discussed in upcoming video) you will see how signals from different sites are used constructively to serve user more efficiently. In release 10, the CA IS about one serving basesatation capable of handling multiple carrier components. but in Release 11 the support for multiple time advances was introduced i.e cells belonging to two different Base station. It is mentioned in the video. Happy Learning.
Two questions dumb perhaps: 1) Isn't SCC eNB too distant for UE to well receive the signal? Thought the UE Rx would be designed to receive the signal within main cell rather than neighboring cell? 2) Can the Antenna operate at two or more carriers simultaneously when running CA?
I am sorry , you are doing a great job. I really understand a lot of concepts easily. However, the accent in this video makes it tedious and so difficult to absorb the information presented here. you are explaining to the whole researchers who they are from various countries not only from India. So I recommend strongly to help all people to get benefits from your amazing explanation, you should use a clear accent not the Indian one . All my respect for you amazing channel.
I have the opposite feedback. I find the author's Indian accent much more pleasant to listen to than the people he paid to do the voiceovers in the earlier videos in the series. I'd love to see some new videos in the same style as the later ones in the series.
Hey I don't understand. So the intra band can have contiguous and non contiguous carriers? Whats the difference between inter and intra. Really confused
+Akhilesh Rao - Yes Intra Band CA can have contiguous as well non contiguous carriers. In simple words Band refers to a chunk of Frequency Spectrum in which the service provider operates. In LTE there can be multiple bands. For example Band 3 refers to 1800MHz-FDD Band, where 1710-1755MHz is used for Uplink and 1805-1880MHz is used for downlink operation. Similarly Band 40 refers to 2300Mhz-Tdd banb, where 2300-2400Mhz is used for operation. You can refer to this link for further clarification. www.radio-electronics.com/info/cellulartelecomms/lte-long-term-evolution/lte-frequency-spectrum.php
+atchut ram - No the component carriers can be of same eNodeB. Sometimes one eNodeB can radiate in different frequency in a particular sector. The different frequencies will have different RRH. In such case the component carriers can be of same eNodeB.
LTE I want to know that what can we do to mitigate the high prb utilisation issue will planning of small cell help ? Cause In my region there is a highly utilised site and to mitigate the issue we planned a macro site nearby but after radiation of that site the performance of the small cell present in the region started to degrade
In LTE-Advanced there is a feature called Co-Ordinated Multipoint which can be implemented to reduce the Inter Cell interference. We are not RF experts maybe you can consult other experts for a better advice.
why did you change the lecturer , the language in this video is not clear at all as it's an indian accent. his English is not clear as well as previous videos. dislike for the ambiguity and inability of understanding what's mentioned in this video.
Very, very important and great explanation, good background, thanks a lot, success

Thanks 😊
Great video! I love your series. I must note that I prefer the synthesized voice as it was easier for me to understand. Keep up the awesome videos.
Really? You are the first person who said that.
The highest rated comment here said the same thing. Anyway, it’s your channel and you can share however you like! I really appreciate the information any way you do it!
@@LTE4G Yes, I like your voice much better than the synthesized voice.
Content is very good, very nicely explained.Thanks a lot
Great video with fruitful information's.. 👍
Kudos for good work and thanks a lot for sharing these videos. Keep up doing wonderful work !!!
Thanks Mr. Solanki. We have finally migrated from Text to Speech converter to human voice. We would appreciate some feedback.
Carrier aggregation 4G+
Keep up the amazing work! It's really helping and enlightening!
Thanks a lot Sadzey.
Thank you very much for your great video :) easy to understand, you use your natural voice though. 👍🏻
+Su-Hyun Jung - Thanks a lot.
Happy Learning.
You finally have the CA #9 done. I should have come back more often. Now I'm over 1 week late :-)
+Alan Spicer - lol! Sometimes we feel that we should increase our our frequency of video upload. You make us realize that it's okay to be slow.
We always appreciate your support.
Happy learning
that was awesome and very informative. thanks and all the best.
Thanks Venkat. Happy Learning.
Great job people, this kind of stuff is really making things easier to understand for beginners.Can you make such effort covering the LTE stack? Thanks in advance :)
This is just beautifully explained . Thank you .
Keep up the good work! Very helpful with understanding. I would vote for the synthetic voice since it does not have accents....
+Shuyu chen - Thanks Shuyu. Is it difficult to understand?
I really appreciated you using your natural voice!
i find it a lot easier to understand than the synthetic ones.
your accent is quiet present, but it is good to understand!
:)
Brilliant video as usual. Thanks a lot!
+HordeMajster - Thanks man

Thank you so much for this content! Which book or books you read to make this work come true?
excellent explanation..
Thanks Sasidhar. Happy Learning.

Great video and easier to understand.
Is it possible for supporting CA with CCs from different network operators?
presentation method is very good. "writing with pencil". which software did you use for this?
I would like to know as well.
Good video, is there any video on Dual Connectivity ? Why we need dual connectivity , what is the difference between DC & Inter ENB CA. Thanks
Very helpful thank you! can you please explain how to know if an LTE device support or does not support CA?
Are you people planning to do any videos regarding 5G NR? Btw great videos. :)
The lane example/analogy that u took would be more appropriate with MIMO rather than CA. :) but anyways A very nice video
AT&T carrier aggregation is godly on the new Firstnet B14 buildouts, It's 4 or 5X CA. 300Mbps is easy
That's great to hear. Tell us more about it. where exactly has it been deployed?
Hi, Great video! Thanks a lot. Do we have any link available for the slides?
Hi, Is CA possbile between FDD carrier and TDD carrier(Band)?
yes it is possible.
If a operator having 3 freq band 2300 1800 and 850 having 20 10 5 mhz freq. What will be the scenario in term of CA in this case. Pls explain.
What is the better band for PCC?
You are showing 5 CC are from 5 different towers. Is that right?
Hey I don't understand. So the intra band can have contiguous and non contiguous carriers? Whats the difference between inter and intra. Really confused

Which textbook can we refer to get more knowledge about LTE
+vishnu vardhan - There are plenty of books available. All the books published by Wiley are good. We refer to them a lot. Happy Learning.
This gives an impression that each component carrier is necessarily from different physical eNodeBs. I don't think it is the truth, is it?
+atchut ram - No the component carriers can be of same eNodeB.
Sometimes one eNodeB can radiate in different frequency in a particular sector. The different frequencies will have different RRH. In such case the component carriers can be of same eNodeB.
Is CA possible between two operators? If yes then is it in use or not?
+Bikesh Shrestha - As of now no. But who knows in future we see it happening
great work (y) ........
can u provide any ppt or pdf for the same???
Hello Sanyam, Can you please specify your requirement?
i need to deliver a presentation and it includes the basics of LTE....so any help u could provide will be appreciable!!
+Sanyam Bansal - There are various presentations available all over the internet. You can refer to them. If you have any doubt you can ask us.
Redmi K50I mobile supports CA. In India telecom giant Jio tested 5g first on this device.
😮
Will carrier aggregation work if there is congestion in nearby cells??
+Rajat Singh - No it won't. The primary requirement is free Resurce Blocks.
LTE But RF congestion is caused by high prb
Can you please elaborate your question?
LTE I want to know that what can we do to mitigate the high prb utilisation issue will planning of small cell help ?
Cause In my region there is a highly utilised site and to mitigate the issue we planned a macro site nearby but after radiation of that site the performance of the small cell present in the region started to degrade

Good Job! I prefer the other voice thou.
+Guillermo Guevara - The robot one or the one in HetNet?
Synthetic voice.
nice video....please tell me how to use carrier aggregation in ofdm code
+Jyoti Arora - Can you please elaborate your question?
the diagram is good， but the accent is a bit too strong.
😅you correct
РТФ, привет
why did you change the lecturer , the language in this video is not clear at all as it's an indian accent.
his English is not clear as well as previous videos.
dislike for the ambiguity and inability of understanding what's mentioned in this video.
Anything
Is that a guy or a new synthetic voice?
+francisco gerardo hernandez rivera - well that's embarrassing. It's a human this time
Thanks, dude. Great job in all presentations.
Lol! We are little confused with your feedback. We thought you didn't like the new voice.
Of course I like it, but it did sound a little flat. Great job guys.
Thanks Frank. We are glad that you liked it. Hopefully upcoming videos will have better sound quality.
happy learning
I used to hear a nice voice on this channel videos, but unfortunately, this video uses an awkward accent and I can hardly understand
Needless music !
🤮🤮
