omggg the best explanation i've seen on yt

wanderfull session and your PPT, thanks a lot

Thank you sir for sharing this knowledge for everyone

It's very usful. Thanks for sharing ❤

Sir your explanation is so clear and simple. Thank you for making the videos.

Hi, why do you say that there is no AS integrity protection in 4G? There is for sure exists as you well describe it in your other video -> "LTE Security Part 7: AS Encryption & Integrity Protection" moreover it is also badly described in this one how the NAS encryption and integrity protection works as it has nothing to do with the eNB, it gets done in between UE and MME only.

I could kiss you for creating this! Been pulling my head reading online till I found your videos.

thank you Mr..Irfan for everything

How mme know or assign EBID?

Thanks a lot to cleared doubts.

Great presentation. Very articulate and clear ...Thank you

Thanks a lot!

are communication between UE and SGW encrypted? with what encryption

Thank you very much for the great explanation!!

Excellent explanation on LTE!!

Fantastic set of videos as I just posted comment for the GTP Primer video. One thing I will say with regards to the DHCP used to give out UE IP address at end of this video, while maybe that it part of the spec, that is NOT the way I see our Cisco customers do it, every instance I see is the PGW's Create Session Response giving out the UE IP address (IPv4 and/or IPv6).

Ive been supporting LTE for Cisco since its inception and trained many people on GTP concepts, but I will no longer do such explanations as yours trumps anything that I have done especially with the assistance of your slides, and so will be referring requests for knowledge in this area, including LTE call setups with your other videos, to your series of videos. Absolutely fantastic, and I dont give out compliments easily.

sir how source enb know the target eNB UE will handoff

Please make an indepth course on LTE or 5G. We are ready to pay for the course.

Thank you for great lecture series!!

Great Video Sir

The series is super good. It will be great if there is a similar one for 5G.

Please create the series for 5g too. You are a life saver

the best explanation I've seen so far. thanks!

I have not seen anyone explains such topics like you. Wow, thank you so much Professor.

Hi. Thanks Irfan for the video. Can you help me understand the word that Irfan uses at 15:57-15:58. He says:"...it knows that the oldest number is 4, so it for a ... " And here goes the word that I hear like "show" or "shock". But what realy Irfan says ?

1 Resource block have 12 subcarriers 7 symbols and 84 resource elements right? if there are 6 PRB's then why resource elements are 72? I know right there are 72 RE in 6 PRB's but I want to know how? I'm confused somewhere.

Thanks for the informative video

Thanks for the video, its really informative.

I mean this guy is in a different level..........Even a layman can understand his explanation............I mean someone missing his lectures , is really missing something in their life.

He really rocked at *2.04*

Thanks for that wonderful explaination!

outstanding presentation sir..and the depth of knowledge that you have is awesome.

u r too too good😀😀😀😀

Thank you very much!!

Hi, in the LTE call Flow slide, i can see 2 annex. GTP primer and S1AP primer. Similar to GTP primer can you kindly also give the slides/video about S1AP primer

Hi Irfan, what about similar videos over NR? After your LTE work we miss it

Irfan , can i get the slides which you have for my ready ref.?

Thanks İrfan! Great tutorial!

Hi Irfan, Thanks for this wonderful tutorial. One Question, Do gateways(PGW/SGW) also open socket ports for each tunnel Id or is it just a logical channel to segregate different users?

Hi Irfan always your vides are very help full and simple

Hello Irfan, Could you please do humanity a favour and upload more of your excellent videos?:) Especially the mobility and power management series.

Do I understand correctly that it is just visualization/simplification that the whole resource block is carrying either RRC or data? As you said in your video about protocols, I think that MAC can multiplex different channels, thus one resource block can have a mix of RRC bearers and data bearers. Is that correct or am I missing something?

This is truly brilliant! Definitely the best explanation of LTE protocols that was ever created.

A great presentation on OFDMA. with 30-40min the complete knowledge have given in utmost depth. Thanks you sir for your great knowledge, way of teaching and very informative slides.... a great reference for me forever.....

UE send UE id in connection req and NW respond same in setup if it did not match UE dropped it . this is not happen in CBRA ?

Hello Sir! I enjoyed your lecture on LTE Architecture. I tried to get the slide from SlideShare. But i didn't find there. Can you help me to collect those?

Pleas , can you given environment or software name to implement these protocol such as AKA ?
