I'm not sure what the "SA" part means but my phone says it's on 5g right now and has done most of the time for a couple of years now.
The 5G standard is a bit of a mess. In the US we heavily rolled out 5G NSA, which means you still have a 4G network core with both 4G and 5G radios at the edge. You get a chunk of the performance benefits without having to replace the network core first. This usually has similar (in practice) performance characteristics to LTE Advanced. 5G SA is an actual, end to end 5G network. The two biggest wins here for an end u…
Yeah. In india jio was SA from the start. Airtel began NSA then I think now they have mostly moved to SA.

#43Note that "G" generally is a marketing term for consumers, the actual tech is 3GPP rev-whatever https://en.wikipedia.org/wiki/3GPP Like 3GPP release 15 or 16 is what we currently know as a lot of in production LTE/LTE-Advanced stuff.
Over 5G you need specialized suits, like fighter pilots have.
Re: Will there be a 7G?
#445G SA isn't still available for the broad masses yet.. and they are talking of 7G? I had the chance to test it in Germany with Telefonica as it can be activated for free. It saves a lot of battery compared to 5G NSA. But they still had smaller problems with hand-overs to LTE and GSM. Colleagues told me that the 5G NSA battery consumption problem is pretty much a solved problem with other basebands and only Pixels are…

Talking is one of the steps towards making things available to the broad masses. You have to start these things ahead of time so they are ready to deploy when the time comes.

Exactly. This is far outside my professional field, but lately I've found that one of the better ways to read the tea leaves of the next decade is to look at the boring 3GPP/ETSI material rather than the consumer-facing "6G/7G" discussion. The interesting part of 6G doesn't seem to be faster downloads so much as sensing. ISAC is basically about making the network capable of sensing the physical environment as well as…
Also if I had a dollar for every end user residential consumer (as a person who runs ISPs) that confuses "5G" with "5 GHz wifi". Like, when your install techs have to explain to a customer why they're getting shit performance in the default 20MHz wide 2.4 GHz channel, and to reconfigure all their devices in a house to talk to a 802.11ax/802.11be 3x3 or 4x4 80 MHz channel AP in the 5.x GHz band.
Consumers literally don't know the difference between cellular/LTE carrier "5G" marketing and the "5 GHz" band on their home router now.
Re: Will there be a 7G?
#46Unlikely. 5G hit the wall on UWB (Ultra Wide Band; 10-100GHz) because geniuses who were doing marketing for its transfer speeds did not realized that such high frequencies are disrupted with minimal amount conductive material in the air - so surprise surprise, 5G UWB does not work when you are behind a wall, it does not work when your big head full of water is in the way of BTS and most perplexing for common folk, it…
There was full team that found out that did the test that 26ghz doesn't work IRL. It didn't even work across a street corner. But they were ignored in favour of some well, career pushers.
In india, jio is using 26ghz for wifi now instead. It's a service called airfiber. This don't even use any 5G. It's a weird custom hybrid solution where all the frames are wifi. Density here means that it's feasible to put the receiver on the rooftop of apartment buildings wherever you can get LoS. So in some sense it's been salvaged and those bands are actually being used. It's a fairly popular service.
URLL failed because it's main immediate usecase was supposed to be vehicle to vehicle comms. And auto didn't want telcos middlemanning there. But there is still hope here.

Don't just look at the indicator on your phone though. Providers are free to scheme with those. Some honestly show the icon when you are on 5G. Others use the option of showing it when you are on 4G (not even 5G NSA) but the network offers 5G on the cell. The marketing guys got involved with this indicator and completely ruined its trustworthiness.
It has been going between 4G and 5G today while hiking, so if they lie it isn't all the time at least. But what do you suggest instead (on Android, a Pixel specifically)?
It depends on the provider. They can choose what the logo means.
Ps I looked it up, it can show it if the cell has 5G even if you're not connected to that at the moment, not if the network has it somewhere.
But each provider makes different choices. They have like 4 options to choose from.
You can use a network monitor app (or the built in one but it's a bit technical) to see what you're really connected to.
Re: Will there be a 7G?
#48The right question: Will 7G be needed? I say no for the next 15 years. Because there are 1425235 other things that are way much important than this.
It may not be needed, but it will certainly be rolled out.
Re: Will there be a 7G?
#49It needs to work backwards, much like Video Codec and ask what do the stakeholders really want or need?
We are closing in to rolling out the last / final phase of 5G. And yet none of the Massive MIMO on FDD is happening. We are still stuck on 32T32R, hardly that impressive considering we have that in LTE already. Not to mention the insane complexity increase from 4G to 5G. And judging from the previews of 6G that seems to be event worst.
If you ask an average user, they will tell you they don't feel much different between 4G and 5G. Yes there are capacity increase and other things. But at this stage I don't think the benefits outweigh the cost of switching. That is both from MNOs and End user perspective.

I've been away from Twitter phone nerds scene for quite a while, what do they use now for those details? Is it still # #service# # or something else entirely?
There's apps for that but yes the built in one is also still there.
I think it's not so much a nerd thing rather than a false advertising one though.
