These industries are pipelined. When generation N is in operation, N+1 hardware and software must be in development, N+2 specifications must be in endless committee discussions phase, and N+3 techs must be worked on in labs, etc.

This is an underrated point. PCIe, DRAM, and WiFi standards are similar. I watched a YouTube video about how PCIe 6.0 was developed, and, damn, the pipeline is long and very complex. Even test equipment has a separate/parallel pipeline.

I'm in Slovakia. We have 4 networks here and they basically have hidden non-compete agreements where no-one launches new tech for masses without at least one other providing it launching it too, sometimes they even coordinate the launch so that all 4 of them launch at the same time...

This same shit happened with launches of 5G NSA, eSIM, Apple Watch eSIM, RCS, and lots of other telco technologies...

At this point all the operators have 5G SA networks up and running for parts of Slovakia (Telekom even claims it covers 99% of Slovak population with 5G SA), but it's only available for business customers in private networks...

They all claim the same stupid reason for this - "most customer phones don't support it, and there are additional benefits for businesses"...

And there are rumors from all of them that they plan to launch it for regular customers by the end of this year...

I mean come on... In a fair market competition the first one to upgrade its network would launch first and heavily claim that they're the fastest innovator in marketing...

And when the network is up and running, why not open it up to regular people? And why it's always the same bullshit type of excuse that's basically trying to say "people don't want/need this"?

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 user are reduced latency (a big focus in 5G) and reduced power usage (the phone doesn’t need a simultaneous 4G connection).

Hah, I was aware of 5G vs 5G mm-wave, didn't realize there was another way in which most 5G was "kinda fake" too.

Yeah. In india jio was SA from the start. Airtel began NSA then I think now they have mostly moved to SA.

5G SA means real 5G. 5G NSA means 4G over 5G NR.

They created an option to use just the 5G radio modem parts with 4G tower equipment to run them in the "Non-StandAlone" mode, so that telcos can start deploying 5G before even it matures. And the modem parts and their specs are called "5G New Radio", which is one of names of all time.

SA means standalone meaning real 5G.

NSA is non stand alone meaning basically 4G with some 5G backwards compatible improvements.

Just because your phone shows 5G doesn't mean it's connected to a 5G station. It also can only be a signaled flag from a 4G station.

And companies are selling electric cars even though not everyone has a petrol car…

I remember people saying the same thing about 4G relative 3G and 5G relative 4G.

2G -> 3G -> 4G were all massive jumps that all enabled new use cases.

I doubt majority of phone users who have a decent 4G connection would notice the difference if they upgrade to 5G.

It's either that or people complaining about "Now I can run out of data much faster". But what people forget is that not all the new tech is to improve it for a single subscriber. A lot of it is to utilize the spectrum better and in that way get more capacity for everyone. Basically, if everyone was on 4G, it would be clogged and slow for everyone.

In Germany telcos using 700MHz for 5G a lot (also for LTE in non-5G regions and sometimes with DSS). So they can create a lot of coverage on rural areas or building penetration.

Telefonica didn't set their signallevel-to-bars-parameters on their SIMs correctly yet. Even directly next to a antenna you only see 1-2 bar although the signal level is maxing out.

700MHz is a mixed bag for rural coverage. Great for punching through trees, but need very tall towers to overcome destructive fresnel lens losses. Higher frequencies are usually better here + more gain!

In terms of signal level?

Well.. that amount of bars you can see depending on the real signal level is just a SIM configuration. In the "newer" networks they aren't configured properly yet.

> 5G SA isn't still available for the broad masses yet.. and they are talking of 7G?

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.
