Welcome to World of Communication. This channel is a joint effort of a group of engineers who are eager to share their knowledge. When we started our career we couldn’t find proper learning videos on LTE(Long term Evolution). This is a small effort so that the coming generations do not face the problems that we faced. Our mission is to provide in depth knowledge of LTE related stuffs.

5G - A Step Towards Smart Ecosystem
This video contains a brief overview of the future of mobile communication i.e 5G. We started with a brief introduction on why do we need 5G? Then we explained the various features of the new radio of 5G. After that we discussed the various technologies that will drive 5G. After that we showed how the new core will accommodate the new upgrades of radio. Then we discussed the various uses cases focusing on how 5g is going to revolutionize our life. And finally we concluded the video by showing how the existing operators can smoothly transition from 4G to 5G.

LTE 4G RAN ARCHITECTURE - eUMTS - INTRODUCTION In previous Generations, the base stations were controlled by a central device. In 2G, it was the base station controller, and in 3G it was the RNC. In LTE, this concept was abandoned, as it required significant resources, because the task was concentrated in few network nodes. Most applications on the device only transmit and receive information i...

2:25,poney station,, this service was used by the muslims since 7th century,, the umayed dynasty made stations in different cities throughout the islamic world, for passing the information from the caliphs/govers to the army or other parts of the empire they used this method,they would change the horses at the coming stations.. you can search/check it,,its in islamic history..

Is it possible to use these videos for a fair booth about the history of communication? It would run on a loop for the education of all who attend.
Sure. We are honoured

Hey Agha, After watching this video I am unable to do anything for weeks
Every one is here just becoz of 7 lakh veiws😂

Thanks guys for sharing the knowledge. Would you do a video about SDN?
Good video for knowledgeable people
Both FDD and TDD require precise timing and it has nothing to do with upstream vs downstream. The LTE frame is very complex, with multiple time slots and all devices have to be synchronized. This is maintained with Precision Time Protocol (PTP) to maintain timing within 1.5 µS. Also, TDD isn't a simple up & down, with guard time as you show. A frame is very complex and often has the uplink and downlink slots right next to each other. It's the precision timing that allows this to happen and the transmitting device actually adjust when it sends a time slot
👍👍👍
Fui obrigado a ver.
hello sir, in fdd, for uplink different frequency and downlink different frequency , whats the use of guard band then?
Great video! Thank you!
USE a real human voice
Why Keisha bald, sorry crishna
best
Where are the new videos? WHy have you stopped making videos for the last 2 years? Please do respond.
TDD is the future.
Awesome 😊
Wow what a great video 👍
Please make more video on 5g. LTE videos really helped me.
For a video on communication, it was a really poor choice to use a robotic voice. It's choppy and hard to understand.

Great video
Brilliant videos!
well i am now grade 9 students. this is my teacher showd us the video so i decide to relearn this topic. i wanted to finish my goal and make my parents proud
thank you, very infomative !
what app do u use??
nicely summarized all features of 5G
Please dont make another video thank you
dont say that>:(
Fun to watch for us DSP fans!
In large events like music festivals and sports events, people use more data in the uplink direction than downlink. Therefore it is necessary to use FDD or modified TDD with uplink ratio higher than downlink.
LONG TERMINAL EVOLUTION
Quite good. I use this in class.
thanks the is the best explanation
best explanation thanks you
So many times and years I tried to study this.. no one explained me this easily.. u r a blessing
Very very helpful, thank you Sir.
Redmi K50I mobile supports CA. In India telecom giant Jio tested 5g first on this device.
Very smart explanation bravo👏
Thanks for explaining the evolution of communication .....
Great Channel, Great Video, Great Content...Pliss, if you could make a video about cRAN, vRAN and oRAN 🙏
👌🙌
Basics of OFDM are explained here well, but how to address the disadvantages of OFDM like high peak to average power ratio (PAPR), OOBE, synchronization sensitivity, and security issues are not mentioned in this video.
are you ok?
