Bluetooth Jammers?

[unzippy]

Anyone messed around with them?

[dinny_g]

[Simon]

They're illegal dude...

[unzippy]

They're illegal dude...

I know. So's speeding.

Just wondering how effective they are, how directional they are, what's the range like etc.
I have a neighbour who I'd like to encourage not to use their bass heavy Bluetooth speaker after midnight.

[Matty]

Just bear in mind that it'll knock out everything on the 2.4 range, WiFi included - for you and nearby neighbours.

As well as, you know, the legal aspect

I know this is the internet, but have you tried talking to them?

[Beany]

Yeah, don't. OFCOM have zero fucking chill when it comes to this shit. Like, at all.

I've had to pull media traces for a couple of incidents like this where we were the second last hop, and, er, Ofcom keep tight timeframes on this, unlike almost everything else they do. One of the rare cases where they don't just amiably gum peoples shins, but go for the throat, teeth bared.

[Matty]

You say that Beans, but I can't find any record of anyone being prosecuted for it. I'm not saying that means you should go ahead and do it, but it'd be reliant on the neighbour(s) being aware of what's causing the outage, reporting it, investigating.

I'd not put the 2+2 together, but makes sense - it's the same tech people use for thefts, so they want to ban ownership (as only currently and offence to use them, not to own):

Don't be absurd. That's the last resort, after illegal jamming and thorough beatings.

God no. I'd rather burn them out than talk to them.

That's why I'm wondering how focussed it is, is it like a targeted beam?

Quite, by 11.30 they're so cooked they don't know what way is up

[Mito Man]

I searched to see if the Flipper Zero does it but apparently not however this came up and I haven’t bothered watching it


Honestly I’d take the easier option and vent carbon monoxide through their letter box. Just sneak round at night and make sure all the windows are closed.

You know for certain that the noise is coming from a bluetooth speaker as opposed to some conventional hifi, or a wireless device of some sort?

[dinny_g]

Completely unrelated but I've one of those Bose Bluetooth speakers and it's awesome.

Not 100%, but this will be a good way to find out.

Likewise - absolute witchcraft!

However, mine goes off at 2130H as I'm a good neighbour.

I'm constantly staggered by how it retains a nice clear sound to really, very substantial volumes given the size of the thing...

Re outages getting reported to networks, all handled automagically by the edge hardware (ie micro/macro cells) if they can't see a return signal from the (weak) mobile phone radio, as if the noise floor gets raised by a shit jammer (and any jammer that costs more than "if you have to ask" is going to be shit), then that'll knock dozens of handsets off at a time (at best, hundreds at worst), which is something mobile NOCs monitor for, same as an IT company would have a massive alarm if they see all their Azure/AWS hosts drop at the same time, etc.

As for not being much in the press, I've seen stuff barely get off of OFCOMs blog, for pure WTA stuff ( https://www.ofcom.org.uk/spectrum/inter ... terference - find *that* anywhere that has a readership that goes above 100 people ) because it doesn't sell papers.

A bit like how you don't read about people wiping someone's AWS account out with their OpenClaw setup in the Sun, it's a niche audience, and wireless/RF/telecoms makes IT news look like the movies in terms of it's visibility to the public. Even if it does get in the press, it's usually because it's attached to something more interesting ( https://www.eadt.co.uk/news/26020769.tr ... d-ipswich/ ) because most people just don't give a fuck about it.

Definitely saw what we were pretty sure was a case we provided samples for in one of the trade rags though, many moons ago - although a bit like that chop shop one, it was basically a case of someone harassing an ex partner, and the WTA stuff was just 'another one for the charge sheet' - the article was there because they talked about OFCOMs involvement, because it's a UK telecom trade rag so OFCOM was in it a fair bit.

As for Flippers, they're regulated devices from an RF perspective, so they won't have the output power to disrupt much from a proper RF jamming perspective, IIRC - otherwise you'd need radio licenses to buy it.

That Braktooth looks more interesting, fucking with the protocol itself and device stacks is rather more elegant, and like the flipper, will be legally fine from an RF perspective.

I suppose the bigger question is, have you considered showing your neighbour bluetooth headphones (even if that's with a note wrapped around a brick that says "BUY SOME SONY WH1000-MX6 WIRELESS HEADPHONES YOU CUNT")?

I basically live in mine, they're way better than a speaker for straight audio quality (no full body bass thump obviously) and there's zero risk of annoying anyone unless you have a habit of singing when drunk.

Wait, how do you edit messages in this applic-

Before wi-fi calling was a thing we used to frequently get asked to supply and install mobile phone boosters in London basement digs. I was a minor shareholder in that business, but we would pre-wire for them and install a suitable aerial cable, but the client had to personally buy it and plug it in.

We only ever knowlingly had one client caught by Ofcom for it - he bought the most powerful one he could find and within a week of builders finishing his neighbours lost all of their phone signal and one of then complained to Ofcom, who came knocking on the door a few weeks later.
No fine, but they took the unit away.
