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

No. I'm suggesting it is easier and cheaper to retrofit equipment. Not to mention dealing with the extra heat.

Pulling the cables down the service shafts from the surface is not the hard part either way.

Stockholm has had 3g in the entire subway system since 2005. Which has then been continuously upgraded. With some very deep lines.

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.

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.

Nobody serves the postcode any more.

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

640 or more customers stream TikTok at the same time

They mean more immigrants live in certain neighbourhoods.

I've not noticed that correlation at all. I just wanted to see who was brave enough to actually speak their racism or whether they'd just suggest it in a cowardly way.

Race and culture are different things.

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.

Huh. I'm really surprised that it could make sense for them to entirely withdraw service when you're (as you apparently are) in a city. But I suppose the Universal Obligation technically wouldn't apply. I've never seen anything like that myself.

> London tends to get that because it has never really been planned. Not particularly true. Go to a city in the world that REALLY has "never been planned", then come back and tell me London hasn't. ;)

If you're gonna do the No True Scotsman thing, the least you could do is give an example of a "REALLY" unplanned city.

I wonder if they considered using the existing metal tracks as antennae, or even https://en.wikipedia.org/wiki/Power_line_communication to feed base stations in the trains themselves. So the ESN in the tunnels runs at 400 MHz, far lower than the 700 to 3,600 MHz range usually used by smartphones. It's worth noting that 450MHz was listed as one of the GSM bands, but apparently was never used: https://en.wikipedia.org/…

I think that part of the article is wrong. The old radio system apparently uses ~400 MHz, but ESN seems to use the same/similar bands as mobile services (700 MHz and above).

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.

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?

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.

One might even suspect that the particularly nice parts of London are full of NIMBYs who successfully petition against the eyesore of mobile masts being put up… (Circumstantial evidence is that a particularly extra nice part of central London has no tube station, ostensibly to keep the riff-raff out, and is the only area with a proposed station on Crossrail 2 that voted against having a new station!)

I have a couple of the 4G-to-wifi bridges they used for the Free Wifi project during the Olympics kicking around somewhere, including the one they used for the promo photos. A friend of mine fitted them in the run-up to the Olympics, and the promo one had been sprayed in beautiful deep blue metallic paint with the logo stuck on.

He got given it to fit on a lamp post in a fairly posh London suburb, but the photographer couldn't come out so it was up there for about a week. When he came to remove it about half a dozen angry locals came up, complaining about the "microwave radiation was making them ill" and the "constant humming from it kept them awake at night", kind of thing, all the stuff they'd been ranting to the local fish-and-chips wrapper about.

"Oh, really? It's been affecting your health that badly?"

"Yes", they all replied, "we're getting a solicitor to take up our case, we're suing over it!"

"Oh," he said, opening the case he'd just taken down to reveal that it was completely empty. "Well, you're going to absolutely hate it when I put one up that's actually got the electronics inside then."
