Another great video, I really think one of the hardest things to keep in mind in VoIP is all the naming and acronyms that are used... Hey, I do have a suggestion though for your videos. Do you think you can number them in order of when you should watch them? When I have your videos up, I have to dig around to find the next one. And some of these sort of require you to see and watch certain videos before you should watch others. I think it would help with your ranking on TH-cam as well, since they can properly list the numbering on the "Up Next" list...
Another random question, GSM itself is still around correct, but it's pretty much been renamed to UMTS, then HSPA+ and finally it just is known as LTE? But at it's core, LTE spawned from GSM? I still hear people speak about GSM, but I assume they mean either UMTS or HSPA+ or LTE but just using the older name of GSM?
Do you have any idea why it's being claimed that 5G would have 1ms latency and 1000x the bandwidth of 4G? Neither of these claims appears to be based on reality. Thanks for your input in advance.
1ms is only talked about in terms of Air Interface latency but some (okay, most) marketing people ignore the air interface part. Also, most journalists do not necessarily understand so they just repeat the claim. Let's say that even if the air interface latency is 1ms, the end-to-end latency will be around 8-10ms. With regards to bandwidth, I don't think people make any such claims. There are claims that 5G will be 50-100 times faster than 4G but that does not take a lot of things into account. It's just poor journalism and ghost writers who copy stuff from here and there.
@@3G4G5G >>the end-to-end latency will be around 8-10ms. But the switches and the server produce at least 100 to 200ms latency. >>I don't think people make any such claims. All the presentations that I have seen and all the marketing material claim 1000x increase. So both the main claimed benefits of 5G are lies.
@@DinarAndFriends It's not that bad. See our misconceptions video: th-cam.com/video/jBEvkjxAsKQ/w-d-xo.html - we have seen 15 ms ping times so 7-8 ms latency. 4G ping times can be as low as 30 ms. What does your speedtest results show?
Good question, we should make a tutorial on that. CU is Central Unit and DU is Distributed Unit. This can then give rise to different split options. Watch this space!
Also...now that I"m thinking about it... if LTE isn't going to exist anymore... what is VoLTE gong to be called?? VoNR? That doesn't sound as catchy lol...
Lol, I don't even know how to pronounce that! So you say that 4G access and networks will be around for quite some time..so because 4G is still around, and 4G supports 3G/2G, does that mean that we'll just keep adding more and more legacy technologies? How will we go about finally cutting some of the older support for legacy technologies off?
Nice and crisp video for someone who would like to start understanding 5G...
Hopefully you saw the updated version as well: th-cam.com/video/oTLpWu5Kf5E/w-d-xo.html
Excellent video completely goes through everything about 5G networks in detail.
Thank you. Excellent to start up the studies about 5G.
Hope you saw the updated version too: th-cam.com/video/oTLpWu5Kf5E/w-d-xo.html

Actually, we have done it here: www.3g4g.co.uk/Training/ - also referencing other channels, not just ours.
Very nicely explained.
Thank you!

No, you need to see the different generations and architecture evolution video. They are all different. GSM 2G, UMTS/HSPA 3G and LTE 4G.

gNb cu and gNb du what are the main difference?

4.5 G Claro

LTE will be around for long time, possibly up to 2035 - 2040. The term being thrown around is Vo5G. That's catchy right 😉?

4G supports 2G/3G but doesn't necessarily need it. Once every phone supports VoLTE then you don't need 2G/3G for CSFB.
Only reading the lines.
Lines of poetry? 🤔
