The tube is ~80db (depending on line) so you're not going to hear it anyway. but, if I was mayor, I would be getting the transport police to have a word with phones on speakers.

Hum. Who should you trust, me or your own ears?

Sorry I don't mean you're lying.

I mean it depends on the line. Old northernline == 80db.

Elizabeth line, much quieter, so you're gonna hear it more

There already is signal on many underground lines, and it’s pretty rare that people are playing things out loud in my experience?

It's because phones speakers aren't loud enough to be audible over the sound of the tube itself! It is noticeable on buses and overground when people play things out load, but to be honest quite rare in the grand scheme of things.

Welcome to the UK where citizens are so apathetic they don't care about aging infrastructure or government money being siphoned away.

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…

You might be thinking of Rabbit: https://en.wikipedia.org/wiki/Rabbit_%28telecommunications%2...

Yeah, I think that's it. Thanks.

Was it a Rabbit Telepoint, perchance? https://www.engagingwithcommunications.com/publications/THG_...

Yes, looks like it. I see it was licensed to a few other companies.

Not to excuse other people's behavior but buying a decent pair of noise canceling headphones or earbuds will make putting up with it a whole lot easier. You don't even have to listen to anything, or you can put rain noises and thunderstorms. It's as much better soundscape than public transport.

Noise cancelling headphones on NYC public transit is insanity.

No, riding the Subway without noise canceling headphones is. The track screeching is something else.

That always hurts. I live in a particularly nice bit of London and there is virtually no mobile phone service other than voice and can only get 80 meg ADSL. Yet the mole people get better service. Grr.

I almost moved into a nice warehouse space in farringdon once only to discover it only got 12 meg service somehow. I didn't even know you could get less than 80meg now.

I moved into a commercial warehouse/workshop space in the center of Chicago in 2021 and was asked to install wired Internet for the building. The workshop that made up the other half of our building had Comcast. All the buildings across the street had Comcast.

Called Comcast. Sent a team out. Told me it would be $69,000 installation then minimum $800/month for gigabit. Complained up the chain. They sent another team out and apologized and told me the first team made a mistake on the price. The install would actually be $71,000.

AT&T was the only other wired option. Best they could offer was 1.5Mbps.

Ended up with a T-Mobile 5G router that gave us a solid 800Mbps down.

Wait, why can't you get Openreach ? Even if it was a new build by idiots who forgot to push the "Free fibre, yes please" button when breaking ground you should have DSL at least.

As a generalisation: OpenReach prioritise areas that have no fibre. If Hyperoptic (or someone else like Community Fibre or The 4th Utility, etc) are in an area then OpenReach will put that area nearer to the bottom of their todo list. It's better if they concentrate on putting fibre into areas that still have 7Mbps wet string DSL than competing in an area that already has one or more Gbps fibre options. Even then, Op…

Do they seriously still do FTTC? In Australia we had an idiot government that stopped our national-wide open access network doing fibre to the premises (i.e. FTTH) and changed to FTTC to “save costs”. After it actually being more expensive (our copper was decades old in most areas and had been under maintained by the old privatised monopoly - and it turns out having to send techs out to fault fix all the time really adds up), they had to abandon the program and now have to go back and are gradually re-doing it with full fibre, costing more money all over again.

It was actually a worst case scenario, because FTTC often actually gives you a sub-optimal point to build out full fibre from, because you need way more cabinets to get decent copper speeds than you need optical splitters if you’re going to a passive optical network, so just building a decently optimised PON network is much cheaper than doing FTTC and then transferring to full fibre.

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

640 or more customers stream TikTok at the same time

Interesting. I would have guessed, that TikTok does the replication on their servers? (like multicasting) Does the native client handles a lot of load?

It makes me sick to see London bragging about this. This is last century technology, and other cities managed to retrofit this just fine, including of course using leaky cable in the tunnels. That it took 20-30 years longer than everyone else is through absolute incompetence and mismanagement. It would have been in place at least 10 years ago if they hadn't screwed up the RFP that Huawei won. And it's not even shared…

The actual reason it took so long was TFL wanted to rent this to a mobile network to create revenue for themselves. It wasn't enough to be cost-neutral it had to make them money.

Well the Huawei winning scandal appeared to be real. But also, I wouldn't be surprised.

In any case, as I said I have actual expertise in this area, and exactly none of being 20-50 years late has any technical reasons. I'm not surprised if there the layers of incompetence go deeper and include what you said.
