That actually does pretty directly show how illegal it is.
For anyone else reading this thread… I am doing a bit, I do not seriously think it would be any kind of a good idea at all to do something like this, I literally just did not know how illegal it is.
It is obviously rather easy to detect a broad spectrum active jammer, it is obviously quite likely you would be caught, lol.
Incredibly, and not at all subtle. It’s also of fairly limited effectiveness in most scenarios, wireless signals are generally a lot more complex than what a simple jammer will cover. On top of the difficulty in transmitting a reasonably large amount of radio power in any useful frequency, you have to also jam side frequencies to avoid fail over and certain noise mitigation techniques.
Honestly it’s not even just that it’s massively illegal, it’s just so wildly impractical. Like, what would you accomplish? Radio waves fall off pretty quickly in strength, so your jammer is going to have a limited range, and if it doesn’t you just knock out flight communications and emergency response while cellular hops to one of the other hundreds of frequencies and like 10 modulation protocols until something works, and it’s going to be insanely difficult to jam all of those at once.
Just jamming 700mhz would involve an antenna array that would be bigger than a person and using the old “moar power” approach sees wattage requirements shoot into megawatt ranges pretty quick.
Yeah if you ask me just walk into your local grocery store or large concrete library, don’t use the WiFi, and bam, cellular waves just stop working. Lol
Hey uh, asking for a friend, does anyone know how illegal it is to just walk around with an active, broad spectrum EM jammer on your person?
It’s more illegal than you’d think.
Just ask Florida Man

Hahaha holy shit that is incredible!

I do my best to impress my FBI handler, gotta stay on his good side, ya know?

My friend thanks you for all the interesting and specific details about what not do and why.
=D
I’m imagining the logistics of setting up a giant wave bubble to envelope a property. I wish had the money for such mad scientists shit
Look up a Faraday cage, much easier to block the signals than it is to jam them.

Yeah but I can’t turn that on and off with giant knife switch
