A character catastrophe for a joker working his last day

ARGO

We had a similar rule when I worked in academia - never let a professor into the lab.

Prototype app outperforms and outlasts outsourced production version

ARGO

Neither. As none of the people presenting it were at the company when I was there, I asked how to make it do xyz - which had been in the phase 2 deliverables list, but not the demo I wrote. Guess what their product couldn't do?

ARGO

I suspect there are many "just for a demo" VB front ends that outlasted the system they originally front-ended for.

I discovered one of mine was still in use 15 years after I moved on when my former employers tried to sell it to my current employers. That was a fun meeting!

Shut off 3G by 2033? How about 2023, asks Vodafone UK

ARGO

Re: Pretty sure 3G and 4G can work at the same time...

Not yet, but eventually.

5G latency improvements don't come until Stand-Alone 5G is live (maybe 2023~24 in the UK). At the moment 5G latency is limited by its signalling running over 4G.

At the radio level there's minimal power difference between 4G and 5G. Spectral efficiency is also about the same.

Right now user density would be much higher for 4G2100 than 5G2100 simply because there are 10x more 4G2100 devices out there. That will probably reverse around the same time Stand Alone arrives. The full density capabilities of 5G aren't needed for handsets though; it's more about Internet of Things.

2G interleaving is only an option in the 900 & 1800 bands in the UK - no 2G2100 devices exist. Unlikely to see 5G in 2100 just yet though; there are plenty of other bands available that require less work. For example 700 & 800 give much better coverage than 2100, while 1800 would be a better option for capacity.

Re: 2G?

"Fingers crossed they'll start making old-school handsets that run on 4G."

Nokia (or rather the people who now own that brand) are way ahead of you there: https://www.gsmarena.com/res.php3?sSearch=nokia+4G

Battery life isn't quite as good as your old model, but still way better than a smartphone.

Shared Infrastructure

Yes. It's in progress, but going about as quickly as you'd expect for something involving four competing companies, a regulator, various central government departments and hundreds of local councils. Details are here https://srn.org.uk/

2G?

Interesting that there is no mention of 2G here. As I understand it, Voda are keeping that running for now. And it could serve as a fall back for all those folk with 3G (or non-VoLTE 4G) handsets. But as 2G is also for the chop by 2033, I guess they'd rather move folk to a capable handset now so the later phase can concentrate on the rather trickier M2M devices.

Aircraft can't land safely due to interference with upcoming 5G C-band broadband service

ARGO

The article specified 3.7-3.98 GHz.

3.7-3.8 GHz is already widely deployed outside the US (as band n78), and 3.8 - 4.0 (n77), while less common, is reasonably widespread. Planes are still flying in the countries that have these.

So either the US has some seriously naff electronics controlling their planes, or this is an FAA / FCC turf war.

2033 is doomsday for 2G and 3G in the UK

ARGO

The shared rural network is supposed to address that. It's 4G only though.

ARGO

TBF there is a 4G version of eCall, and anything being sold now is on that version.

Cars tend to last longer than handsets though, so likely to be quite a few still using the circuit switched system in 2033.

Smartphone chip house Ziguang Zhanrui records 14,726.1% growth in China

ARGO

Doubt it's due to Huawei

>Ziguang Zhanrui is filling a gap left by the decline of Huawei HiSilicon

Not so much. HiSilicon chips are mainly high spec, while Unisoc is in the value tier.

They're more likely picking up business from Mediatek's attempts to move upmarket, alongside Chinese networks efforts to move 2G/3G users onto 4G. The latter is significantly increasing the number of entry level 4G handsets being sold.

Re: 5G?, Decent 4G and Voice Would be nice In Hertfordshire

But perversely, non line-of-sight can be faster if you have a decent signal strength to start with - MIMO needs multiple reflective paths to work. (Clearly this means MIMO transmission is witchcraft.)

Re: Mediatek

Yes they do. As do Unisoc.

BT to phase out 3G in UK by 2023 for EE, Plusnet, BT Mobile subscribers

ARGO

Re: Rural coverage is still very poor

The spectrum currently used for 3G doesn't go away though - it just changes from 3G to 4G. Coverage of that spectrum stays the same.

It's even possible coverage will improve, but for a different reason; the networks are under OFCOM pressure to hit 90% geographic coverage. A site they are already visiting for a 3G-4G switch is a prime candidate to have 700/800 added at the same time. And that spectrum goes much further.

(You still need a VoLTE handset to use it though)

ARGO

Re: Provided...

There are a decent range already. You won't find many in operator stores, but they frequently appear in the Sunday supplements. Doro seem to be the market leader in the UK.

ARGO

Re: Shame, but inevitable

The UK operators have been refarming 3G spectrum to 4G, so where you used to get 10 MHz bandwidth (assuming a DC cat 24 handset) you probably only get 5 now.

700MHz for 5G?

Should mention that 700MHz can also be used for 4G, and there's a very good chance your current phone already supports it.

Re: Huawei was intent on spending $1.2Bn on it's on a Communications Research Facility in UK.

Also interesting that these new vendors don't have to run their kit past GCHQ. Presumably ORAN is in some way immune from shoddy coding practices.

Re: Ridden Out Of Town On A Rail

Presumably that's why they did it on the Jubilee Line first - it has platform gates.

ARGO

Re: Thanks I hate it

Leaky feeders are indeed well known, and fine for the more recent bits of the system. I'm told that's how the Jubilee Line cellular coverage works. But the older tunnels don't have space on the walls to fit those without moving other things. There's space at the bottom, but running comms next to high power electrics would be brave - and you've then got the train floor between the antenna and the users.

Citibank accidentally wired $500m back to lenders in user-interface super-gaffe – and judge says it can't be undone

ARGO

There's some background missing here. The loans were in the process of being refinanced; some lenders had agreed to the new terms, others had not. The ones who kept the unintentional repayment are all in the latter group. The loans were trading at ~40 cents in the dollar, so full repayment is a bit of a result.

Former NCSC chief says US sanctions made Britain strip Huawei from mobe networks

I take it you haven't seen Huawei's proportion of worldwide network sales. They will be supporting that kit long after 2027. There's a fair chance that that kit removed from the UK will be resold somewhere less picky.

They've only sold the physical towers. They still own the network kit that sits on them, and the core network that connect it all together.

Jio use Samsung for 4G. So a bolt on to that for non stand alone, or something completely new in stand alone?

The latter is easier, but rather less useful at present.

UK smacks Huawei with banhammer: Buying firm's 5G gear illegal from year's end, mobile networks ordered to rip out all next-gen kit by 2027

ARGO

She's probably the closest to it, but has experience in fixed broadband not mobile. And her pronouncements suggests she knows nothing about 5G security mechanisms or network architecture.

ARGO

Yeah, it's amazing how many politicians are suddenly experts on network design. And yet in 20 years in the industry I've never run across any of them.

ARGO

Logic?

So Huawei are (eventually) banned from providing 5G base stations - where all the traffic is strongly encrypted - but not from the 2G & 3G networks where the encryption is rather more ropey.

And this is about security you say?

Not going Huawei just yet: UK ministers reportedly rethinking pledge to kick Chinese firm out of telco networks by 2023

ARGO

Re: Scepticism...

And if Huawei's only providing the radio nodes and antennas, what exactly would a backdoor achieve?

All 5G traffic is encrypted through to core. Nobody can (yet) crack 5G encryption, let alone do it live.

So that just leaves potential for disrupting the infrastructure. If that's the concern, perhaps look at how much UK infrastructure is directly owned by Chinese companies rather than just using equipment provided by one?
