Just to add a piece of data to support this: > It turns out the phone signal inside the station can be better than the one above ground I was surprised when I noticed I had 5G in the tunnel, ran a speed test and hit 641Mbps down! https://www.speedtest.net/result/i/6831252952

Great - what does customers do with 640 Mbps downstream in the metro then? :-D :-D

The Paris metro figured this out perfectly way back in 2021 - full bars, 5G.

The Paris metro is mostly cut-and-cover. It isn't very deep. The deepest tube lines are around 60m underground.

Are you suggesting the mobile signal comes from above the ground in Paris?

> There’s another distance limit at work here, and that is the speed of light. It takes milliseconds for the signal in your phone to reach the hotel above ground and be handed over to the mobile network. It takes roughly 100us for light to travel 30km – Can you explain how the speed of light is relevant here?

.. and in 1mS it travels 300km. Maybe they just want to sound technical, somewhat to match the rest of the article. They certainly didn't use chat gpt, so maybe that's a good thing.

London, increasingly common. I’d say a third of the time when I take the tube. Combine that with people making loud calls, 100% of the time. But I find people imposing their music or tiktok videos more obnoxious than a builder discussing his next job a bit loudly.

A third of the time? Sorry, nonsense. I use the tube several times a day and it's a real rarity. I do worry about the tube becoming a cacophony of phone calls, but really? Everyone message now anyway so I reckon that'll be a rarity too.

I think it will depend on your route and the time of your commute. I see fairly distinct behaviour at different times on the tube & Elizabeth Line: come in or leave late and it's full of people who are much less considerate, go in with the majority and there's a bit more social pressure against being inconsiderate.

That directly goes against the earlier post where you said you lived in a particularly nice part of town

There are a good number of places in the world where people of varied incomes live relatively close.

London tends to get that because it has never really been planned. It just grew over the course of 1600 years and absorbed other areas as it went. There are plenty of areas where a row of £20m+ homes are opposite blocks of 3-bed flats that go for a hundredth of that price.

Hundreds of years ago, before the rail or underground network, you still needed plenty of working class to live near where the rich people lived as the rich people still needed shops, servants, etc.

Having the city split into individual boroughs means that each borough had to provide for the full economic spectrum. The really expensive boroughs still have plenty of social housing and arbitrary divisions of land mean that things but up against each other from different boroughs.

However, new developments don't always get it right, when big green-field or brown-field sites are converted to residential they often struggle to get the correct right, and you end up with bigger areas that only cater for a subset.

National planning laws are also circumvented or gamed. If a new site requires a certain percent of "affordable housing" the developers will often agree (with the local borouhgh/council) to roll that over with another couple of projects and then build most of the "affordable housing" all in one place, and the diversity of individual areas is diminished.

As you say, there are plenty of other places in the world where this is the case, most of them in countries/cities that have existed for hundreds or thousands of years.

What is the thing with people using phones without headphones? And making calls on public transport? When did that become a thing? It’s the most obnoxious selfish behaviour and it shocks me every time. It’s not just Gen Z either, I’ve seen a few boomers do it and even a couple of millennials.

Ten of so years ago I was on a train and the women opposite me gave all her credit card details to someone over the phone — anyone close by could have had fun with them

Is that still a thing in the USA that you can buy with just a credit card number, validity date, name and 3 digit code?

In the EU we have psd2 mandating a second factor. Usually an app where the transaction has to be confirmed.

I'm old enough to remember the first attempt at 'mobile underground'. Maybe I've forgotten the name but it was something like BT Phone Zone, though google returns zero relevant results, so perhaps it was called something else. In lieu of public call boxes, BT trialled a base station that was installed in some tube stations (almost certainly Oxford St and Tottenham Court Rd), and with the correct 'wireless handset' as…

Was it a Rabbit Telepoint, perchance?

I have the opposite problem where I can only get HyperOptic. Not even OpenReach stuff. No problem with bandwidth but zero price competition, and 5G broadband isn’t viable either. Going from £70/mo for gigabit to £65/mo for 500mb is insulting.

Urgh hyperoptic is dog shit as well. CGNAT or pay extra on top of already insulting prices.

I feel like I'm going crazy. Hyperoptic is fine. I pay 40 quid for gigabit, and it's stable and fast.
