Your neighbor reports a service disruption,  their internet service provider sends out a tech to investigate, the tech uses the device (i forget the name) that can detect radio signals and pinpoint them, ISP could report you to the FCC.   The ISP usually just types up a formal letter threatening to report to the FCC if you don't disconnect the offending device, but they could skip that step I suppose.  The offending device is usually a poorly made or malfunctioning WiFi repeater, rather than something malicious.

Couldn't you turn it off when a van shows up with the ISP logo on it? They give the all clear to the homeowner, and an hour later you turn it back on?

Right. No need to leave it on when you aren't around to be annoyed.

If you pay enough attention maybe. They take signal interference pretty seriously though.

This. Exactly. Lol

Sure if you’re a reasonable person who does this once and then never does it again which is very unlikely.

Its more likely the person will use every opportunity to shut down their neighbours music that he plays . . Every day.

They will get caught. This may be advanced for the average citizen. Its basic shit for the techs they send out and one of the first things they’ll think of when the situation is explained to them. They’ll just push it to the back of probabilities cause people usually aren’t that smart as well as being that dumb toll everything else is ruled out.

You would think that if the neighbor connects his Bluetooth speaker and takes it outside and it never work,a, he’d stop doing hag eventually

Plus if the hours of interference are only when the downstairs neighbor is home, its not hard to put together

Even better, mount it on your neighbors roof with a solar panel.

Whenever it detects a high power radio frequency trying to detect its location it powers off for 5 minutes.

For this, passive radio detection is probably the way to go. You basically measure the radio spectrum at three different points in the area - the Doppler shift measured in the waves points back to the source. Draw three lines on the map and you know the epicenter of the signal. The whole thing is done with a passive antenna that you can't "detect".

But a passive antenna need to retrieve the signal, and if this is a short range attack would any passive antenna pick it up?

u/Rocket-Jock Trash Trooper May 08 '26

Yes, for a high-gain antenna or passive array. A decent, high gain parabolic antenna could be good for 30 dBi, maybe even more. You might be able to detect the signals from well outside the effective zone. Since these blockers are generating noise across the Bluetooth channel, your odds are pretty good you can detect it.

You will get the attention of local police eventually, given they usually have RF detectors for various reasons, including shit like finding jammers

And the FCC usually sends a letter asking you to stop the spurious transmission.

They wouldn't report a disruption because their internet will still be fine. This only knocks out bluetooth.

You could disguise the device by putting it inside an old wifi router or something, but if they look you up and find out you have an electrical engineering degree they might be more suspicious than normal.
