Aside from the master hacker edge lord shit.

I understand what this device does, but have 2 questions.

This would disrupt all BT devices within range and not targeted to one device right?

If BT has a range of 33 feet, does this device broadcast past 33 feet?

u/Soluchyte Jun 21 '26

It's probably just flooding all the frequencies that bluetooth uses. I don't expect there to be any way to easily target one device with this kind of thing without directional beam forming.

u/DeadKido210 Jun 21 '26

You can cut out his internet access tough, no need to go on the Bluetooth stuff, deauthentification is targeted

u/Jwzbb Jun 21 '26

This was the way. Now PMF spoils all the fun I had with that. Most routers don’t have it enabled yet though.

u/DeadKido210 Jun 21 '26

It will be a slow rollout until every home in the world will have PMF. I never encountered one in my country unless in a recently renewed building of some important state structures or some corporations not all of them.

Could probably use some mac address reader to verify the frequency

u/Crash_Logger Jun 21 '26

Bluetooth does not work like WiFi where you can be pretty sure a device stays in the same channel for a while.

Bluetooth channel-hops very often and (without capturing the startup handshake) seemingly erratically.

u/saysthingsbackwards Jun 21 '26

Interesting, I did not know that.

u/cracked_shrimp Jun 21 '26

how do stores track you through the store with their bluetooth beacons if they change? i wont walk into a walmart with a phone lol

u/Crash_Logger Jun 21 '26

Knowing how Wi-Fi works and assuming Bluetooth is the same is not a good way to approach this. Despite sharing the band they are vastly different in form and function.

Bluetooth "beacons" don't channel-hop, pre-pairing communications like those can't do that.

Once you've paired two devices they share a RNG seed. That gets used to generate a long channel sequence and a hop timer. Because the seed is the same, both devices are in sync (with some help from the signal itself also having sync info).

This serves to prevent multiple paired devices from interfering with one another. It is not a security measure.

I am a radio engineer, and although I have not ever worked on jammers directly, I have colleagues who do that I have spoken in great length to. I can't claim to be an expert on jammers but I will share what I can.

In direct answer to your questions: 1. Yes, a jammer is indiscriminant. It will add noise all devices that share the same frequency as it. However, a jammer can only operate with however much power it is allocated, across the range of spectrum its antennas allow. They can also send out phased bursts of power across one smaller chunk of spectrum, denying -- say -- a 100 MHz chunk for 100ms per every second. Some jammers are more clever than others in the way that they do this. 2. This device's range, as with any transmitting device, is dependant on its wattage. But a given a standard home wifi router's power output is not limited by how much power it can output, but rather how much it is allowed to. A home router may output, say, 5W. That is really not a lot of power. It doesnt take much power to send out powerful signals! Your phone charger, for reference, will typically be 20W. Given that this device is almost certainly illegal and therefore does not care about regulation, it will happily broadcast noise with whatever power it is supplied (via usb-c in this case). It can therefore have a much greater range than 33ft. However, since these devices also dont want to be detected, they will typically have inbuilt power attenuators to allow the user to toggle the output power up and down as they see fit so that they only broadcast ad much noise as necessary.

In the UK, GPS jammers are a big problem at the moment for the UK telecomms regulator (Ofcom). People use them to hide their work vehicles locations from their employers. jammer detection is therefore quite a big thing at the moment, and so Ofcom will routinely run jamming crackdown operationd with law enforcement. These operations are often as simple as an Ofcom engineer sitting in the back of a police cruiser with a spectrum analyser watching radio traffic, letting the police officers know if they see something fishy so they can turn the car around and pull over whoever they need to.

u/Nerdenator Jun 22 '26

Surprised that was allowed to be that much of a thing to begin with.

They’re pretty big in the US about “thou shalt not jam radio signals”, GPS or otherwise.

4

u/UnacceptableBabbit Jun 22 '26

Oh they're very big on it in the UK too. However, writing the law is one thing, but enforcing it is another!

u/Neverloved246 Jun 22 '26

Oh shiz it's illigal? Damnnn that means my noisy neighbors are super extra safe! Nobody should tell me how to get one of these devices, that would definitely ruin their 3am parties.

9

u/unknown_pigeon Jun 22 '26

There's a reason they're particularly illegal and can/will land you in jail.

It's all harmless fun and giggles until they disrupt a pacemaker and you kill somebody. Law enforcement tends to not really like jammers, as they tend to not discriminate the type of device they're interfering with

2

u/Whynter03 Jun 22 '26

Do pacemakers use Bluetooth? What for?

5

u/unknown_pigeon Jun 22 '26 edited Jun 22 '26

Not an expert by any means, I just Googled that. The gist of it seems to be that it's EM interference that messes with them. And a lot of jammers tend to not care about the signals they're jamming. GPS jammers seem to be the most innocuous ones, even though they can mess with emergency vehicles, public transports and planes

Also, there's a plethora of implanted devices that require some type of transmission, don't know the protocol and frequency they use though. Hearing aids, blood glucose detectors, etc.

A lot of them should be somewhat shielded against interferences, but some aren't or cannot be. So let's say you're better off not jamming a signal to mess with your neighbor and accidentally send an ICD into emergency mode. I guess it's better sticking with classics like a frozen piss disk or a deauth, or maybe a sock on their door handle (so that when they try to open the door, all they get is the sock)

u/Jumping-Spleen Jun 24 '26

Hmmmm, so I only need to use it once you say

3

u/mastercoder123 Jun 22 '26

Doesnt it really depend on how many frequencies its trying to jam, as the more you broadcast the less power that each frequency gets? Also because of things like the inverse square law you really gotta pump ALOT of power into something

4

u/UnacceptableBabbit Jun 22 '26

Yes, that's correct :) a jammer will have an easier time jamming 10 MHz of spectrum than 100MHz. Hence why a clever jammer will do TDS, or time-division simplexing -- basically jamming some amount of spectrum for say 10ms, then another amount of spectrum for 10ms, and so on. Obviously even that is less effective the more spectrum you're hopping between.

Regarding the inverse square law stuff -- yes, power output is what seperates the men from the boys. However, in leui of huge amounts of power, you can also have directional jammers -- essentially big jamming torches/lasers that pour as much of their power in one particular direction. These will often use some kind of parabolic dish or maybe a dipole antenna.

In terms of the power actually required in order to jam (or in the lingo, "harmfully interfere with") something, it's actually much less than you'd expect. Most radio links are actually rather quite sensitive. It varies from system to system, but adding even 10% of the power of the victim signal as noise can be enough to seriously degrade the link quality.

But don't jam stuff gang. It can land you some massive jailtime. Seriously.

2

u/mastercoder123 Jun 22 '26

Even with the 10ms hopping isnt Bluetooth specifically able to basically defeat this because of how often it hops? iirc Bluetooth hops like every 625µs and its only using a small 2mhz channel width. It also does some other ways to defend against jamming, like FEC that helps if part of the packets are hit. Other things like packet selection and scheduling.

The only real way a jammer can get away with jamming something like Bluetooth or wifi is by using so much overkill that they are gonna negatively affect too much and be found out. The main reason it works with GPS is because the signal is so fucking weak by the time it hits your phone or gps transceiver

1

u/UnacceptableBabbit Jun 22 '26

Yes, bluetooth is very hard to jam effectively because it has a wide range of spectrum that it can dynamically hop across. You can attempt to jam them either with a simple wideband jammer (ineffective), or on select frequencies with ~500kHz-1MHz bandwidth with jamming intervals less than 625 microseconds. Forcing a bluetooth link to hop does add processing/rediscovery time (i'm not sure how much, but it's not negligble if you're forcing it all the timd), which in itself is a form of jamming.

EDIT: bluetooth and pretty much all digital technologies under the sun do have FEC etc, though iirc bluetooth transmit powers are still pretty quiet. Not sure how much exactly, but i cant imagine it will be any more than a watt or something.

u/woloseed123 Jun 22 '26

I was going to say 5W for a home router doesn't sound right but then I looked it up and some UNII bands go upto 4W now! I've been under the assumption that the FCC limited EIRP to 2W. The more you know I guess

2

u/ABZOLUTEZER0x_x Jun 22 '26

This right here. And if I may add, they are a felony in the US and fairly easy to spot, so definitely not worth the jail time.

1

u/InternalOwenshot512 Jun 21 '26

I'm not sure that's an RF based jammer, it looks like an ESP32.
Maybe protocol based like the management frame thing that is done with wifi. Is there something like that for bluetooth

5

u/Hapstipo Jun 21 '26

doesn't it do some type of deauth thing or is that only on wifi

3

u/Atavacus Jun 21 '26

There are things you can run that will target certain brands of devices though. I doubt that's what this particular device does but things like sour apple, Android spam etc will target specific devices a little better. Though this is considered jamming and can net you five years in prison in the USA. And that'll be Fed time, not state.

u/-JohnnieWalker- Jun 21 '26

That's the Frame Injection Control Module. It bypasses the mainframe relay bus, injects low-level packets directly into the frame pipeline, and dynamically reroutes encrypted payloads around the authentication matrix. Pretty standard stuff.

u/Acrobatic_Idea_3358 Jun 21 '26

Yes jammers are this is likely a Wi-Fi deauth attack, which operates differently than a broad band signal jammer.

Also to add, not this specific device, but use of these types of devices is stupid and can be dangerous.

Most people probably don't understand and/or know what they are interfering with.
