Re: Jamming the WiFi channel

Hi Derek,

Yeah, I accept all the things, after all, I have to, as I tend to wireless systems and their security and some more stuff with regards to radios and SDR and things. But what I suggest is that we guys start a separate application/discussion area for these kinds of things (because I personally as well to some extent historically believe[ https://doi.org/10.1080/03071847709428739 ]) that this must be an integral part of the ecosystem. I accept the part where one needs to have proper RF enclosures or a SCIF to conduct these emission experiments (unless it a wide range of open testing).

I propose that we have a separate discussion for things like this, just for educational purposes, because I feel that there is too much "Telecommunications" research happening, but very quiet a limited discussion regarding "What is the best way to build a signal for a jammer from its spectra" or "What happens in spatial resolution compromise in a RADAR system and how this can be a problem". Basically, I am trying to say let's break the taboo about the discussion about EW and SIGINT and ELINT using SDR and GRC. After all, radios are fun.

This part goes to Mr.Robert
In my humble opinion sir, I don't agree with you not one bit. Technology is a dual-edged sword, and radio is a knife with jagged and pointy edges everywhere. There is no concept of morality (at least it cannot be quantified by any metric). EW is an integral part of our life now. And people who are into it can and should be able to learn it, no matter what, no matter the cost. This is knowledge and as I can say GRC taught me a lot, in terms of learning and sharing their knowledge be it in blogs or conferences or this mail list. In fact, this kind of question needs to be encouraged but with significant warning labels around them.

To my humble opinion, this is simply not allowed and must therefore from a moral point-a-view not be promoted.

On a serious note, I know that all of us know how to build a jammer, in case of questions like this how do we deal with it?
I mean I can do both sides, in the spirit of sharing the knowledge I think that someone should tell the person who is doing it on how to build a jammer (in this case) or should we not help the person?
Or should we condemn these acts?

Probably even in France it is illegal to jam radio signals. I sure hope
that NOBODY helps you!
