2.1 - TDD vs FDD in 4G LTE

[@LTE4G]

As many of our subscribers were complaining about the Text-To-Speech converter that we used, we uploaded a new version of the same video with human voice. Here is the link to it. kzbin.info/www/bejne/g3uppHd4r7qla7c Happy Learning.

i have never seen any video more simple and clear than this one , i appreciate it

[@juju-lips323]

This is fantastic. I remember looking for a video like this a few years to explain fundamental characters between FDD and TDD and there were none available. This is perfect. I like how you have also painted a commercial lens as this helps to understand business decisions. Very well rounded presentation for such a short clip.

[@LTE4G]

Thanks Mr. Talia. We are glad that the videos are serving a purpose. Hope you like our other videos as well. Happy Learning.

[@juju-lips323]

LTE Yes, based on the quality of this video I have subscribed to your channel and will be keenly browsing through your other videos. Keep up the great work.

[@christosvrettos6742]

Great work! Really high quality material. Thank you for assisting me to understand the base concepts of these techniques!

This is amazing work. Keep it up guys. I would love to watch more videos based on LTE and 5G or anything new going on in Communications. This channel will be very unique in no time and will be noticed.

[@LTE4G]

+MagicSystem11 - Thanks Magic. That was the idea. We wanted our channel to be unique. Stay with us. we will keep on uploading LTE related videos. Happy Learning.

[@visionofwellboyofficial]

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.

[@divinelight1971]

Good material presented in a extraordinary way. Was able to learn in a much better way. Thanks for your efforts and keep up the great work.

Have you had symptoms such as fatigue, headaches, poor memory, difficulty sleeping, and lack of clarity in your thoughts? It may seem like these could be the results of daily stress and frenzy, but there could be another culprit. All of these are symptoms of electro-sensitivity, which is something that more and more people find themselves affected by. Studies conducted in 1997 found "less than a few cases (of electro-sensitivity) per million", however now as much as 2.5% of the population is affected by electro-sensitivity. Even with the most moderate calculations, electrosensitivity is 10,000 times more common today than it was 20 years ago. Why could this be? Electro-sensitivity and its symptoms appear to be triggered by certain microwave frequencies of electromagnetic radiation. Due to their high frequency, microwaves allow for higher transmission rates and smaller antenna sizes, which is perfect for high-tech devices that are constantly getting smaller and faster. These are devices such as cell phones, tablets, laptops, and any device that can connect to Wi-Fi, which can now include TVs and refrigerators

like that u also answer all the comments

[@LTE4G]

Thanks for the lovely words George. But We are sorry we can't help you with that.

Please make more videos on VoLTE.

[@LTE4G]

+Freebirds 360 - We will get to that but right now we are following a schedule. See the video- channel roadmap, where we have discussed about the topics that we are going to cover. However if you have any VoLTE related query you can ask us on Quora. We are using the same user name and photo. We will definitely answer your queries.

[@sanjayagangatkar5109]

Thank You, good way to learn LTE concepts.

[@LTE4G]

+Sanjaya Gangatkar - Thanks Sanjay. Don't forget to share it with your friends

[@mohammedal-haddad2652]

Thanks for the good presentation.

[@LTE4G]

+Mohammed Al-Haddad - Always happy to serve. Happy Learning.

[@James_Knott]

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

[@horizonbrave1533]

So I'm not getting the difference between tdma..and tdd or fdma vs fdd

[@mhrii88]

Very useful material!

[@LTE4G]

+Ann Ayson - happy learning. :)

[@sujoysaha9768]

HI!! Can anybody explain why we can not communicate both ways for Half Duplexing method?

[@LTE4G]

+sujoy saha - we can communicate both ways. But not simultaneously.

[@sujoysaha9768]

Thank you. but please tell me why in Half duplexing we cannot communicate simultaneously.Is it then became full duplexing process? or there is any obstacle in half duplexing which not allow both way communication simultaneously.

[@LTE4G]

+sujoy saha - You are getting it wrong. The system which cannot communicate simultaneously both way are called halfduplex not the other way. Actually there is no system which is completely full-duplex. In full duplex systems we just use two different channels simultaneously for uplink and downlink. You can say full duplex is a combination of two half duplex. Hope we were able to clarify your doubt.

[@sujoysaha9768]

YES....!!!! Thank you very much for your valuable reply.
