Re: This doesn't seem right...
As someone noted above, 6GHz doesn't play nicely with walls.
But it's not inherently better for either technology - just make sure there's no wall between you and the access point / cell tower.

Yup, various permutations of network signal time of arrival positioning are already in 3GPP.
They've been gradually ramping up the accuracy requirements over the years.
Starting from ~100m in GSM days, they've now got the 5G iteration to a best-case accuracy of 30cm.
(Should also note that Cambridge Positioning Systems had a way of getting down to ~10m around 20 years ago)
...it's almost identical to the proposed remit of the CMA Digital Markets Unit in the UK:
There is a list in the regulation linked from the article. It's a slightly weird selection though, and only adds up to 15 if you have more than one item in some of the categories:
• back cover or back cover assembly;
• front-facing camera assembly;
• rear-facing camera assembly;
• external connectors;
• hinge assembly;
• mechanical display folding mechanism;
• mechanical display rolling mechanism;
• display assembly;
You may be pleased to hear the draft regulation actually says this: "for a minimum period from one month after the date of placement on the market until 5 years after the date of end of placement on the market"
Which is rather different from 5 years from launch.
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.
"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.
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.
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.
>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.
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)
If only someone in the CMA had anticipated that might happen before the merger was approved.
Perhaps they would like to employ a few of El Reg's commentards in future?
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.
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.
