Beginners: 5G Spectrum - Long Version

[@madhulikasaxena5341]

Thanks for sharing wonderful, meticulous hard-work on 5G Spectrum.

[@joelabarre56]

So, I absolutely LOVE your videos. Thank you for putting all of these together.

[@nunodarochaborges9575]

Spot on analysis. Extremely useful! Thanks

[@brendakoldyk1647]

The problem with the higher frequency is that rain, snow and fog will absorb the energy so reception will be weaker so you need more power to drive that single farther away. Not sure how healthy that it. Just a thought. Also like he said the in the video it has a harder time penetrating through building and walls.

[@3G4G5G]

"Not sure how healthy that it" - there is an upper limit on power hence for higher frequencies we will have to use more base stations and will only be used for denser deployments. It won't be feasible to provide high throughput coverage everywhere.

Very well explained, Thanks a lot.

[@daysmith5945]

That cleared up plenty. Great video

nice one

Thank you for the knowledge shared.

Excellent

Thank you for your work.

Thank you! Very helpful.

Thank you for clear explanation

In 3g we have 5 Megahertz carrier size, what is the carrier sizes in 5g?

[@3G4G5G]

It's variable like 4G, all the way from 5 MHz-100MHz for FR1 and 50 MHz to 400 MHz for FR2. See: 18:02 for FR1 20:40 for FR2

Will 5G NR and UE abinitio cater to waveforms to operate in 2/3 G frequency bands when they become free???

[@3G4G5G]

Not sure we understand the question

[@ArthurCor-ts2bg]

@@3G4G5G I mean to say that once 2G and 3G networks close down 800-900 Mhz/1800-1900 M Hz GSM and IMT 2000 bands will become free.... Will 5 G not utilise these freq bands as part of FR1??

[@3G4G5G]

@@ArthurCor-ts2bg Yes, operators are already "refarming" the spectrum. Sometimes they take a part of the spectrum, sometimes they take complete spectrum. Different approach in different countries and operators.

Long version vs Short version?? Long version only please! lol great one!

[@3G4G5G]

One of the feedback we received was to try and keep our videos under 10 mins. We tried but didn't quite succeed with the short one, its still 13 mins.

[@horizonbrave1533]

@@3G4G5G I don't know..I love the longer 15 min+ videos...I can get my morning coffee and notebook and really study! I know it's more work for you all, but perhaps this idea of having a long complete video of like 25 minutes , and then edit it, into smaller bite sized chunks, and then upload both the long oen and the smaller edited ones?

[@3G4G5G]

@@horizonbrave1533 We don't have a problem. Some people complain our videos are sometimes too long and too detailed but we guess it depends person to person. In this case we wanted to make a short one for people who are not very technical but we won't be doing it regularly though. Enjoy!

[@asifm9434]

Sir What is carrier spacing range in 4G LTE technology? do you have any video that explains various 5g nodes like AMF, SMF etc?

[@3G4G5G]

It's fixed 15KHz. Yes, we have SBA as well. Start from here: www.3g4g.co.uk/Training/

[@asifm9434]

3G4G sorry my question what is carrier bandwidth for 4g?

[@spartacosuarez5724]

Thank Hommie.

[@asifm9434]

Sir what we mean non-Millimeter wave or Millimeter wave?

[@3G4G5G]

Hello Asif, we made a short video explaining this. See if it helps: kzbin.info/www/bejne/gp7SeZd-eNifldU

[@ahmadmansi5636]

Too difficult to follow with the numbers and the slide At least highlight the number when you say it or move the curser

[@3G4G5G]

Sorry to hear. Just download the slides and go through them first then come back to the video.

[@ahmadmansi5636]

3G4G 3G4G thank you really... You must have worked a lot on the slides and everything. Anyway I completed the video and gained lots of knowledge. I have a question about the different frequencies; When a telecom chooses one or two low frequency, one or two med frequencies and one or two high frequency: does that mean that the same 5G that the telecom will have will have the characteristics of the three frequencies (low, med, and high) combined? And another question please: Is the bandwidth a necessary component as much as the frequency? Is it like the breadth of the highway if we consider the car is the signal? Does higher bandwidth mean more coverage?Throughout? Or number of users? Thanks again

[@3G4G5G]

@@ahmadmansi5636 More bandwidth can mean more throughput for the same number of users or same throughput for more users. There is a video on that: kzbin.info/www/bejne/fmecqWqlfM2ne80 Actually you can launch 5G with very small amount of spectrum but then it would be as slow as 2G/3G. Will show a 5G icon but QoE will be poor With regards to the layers, it's exactly the same 5G. Not all operators have spectrum in different layers. We show examples in the end of this video. It just means that with low spectrum you can have better coverage but smaller bandwidths, poor throughput and with higher frequencies, smaller coverage but very high throughputs.
