Re: Jamming the WiFi channel

[Derek Kozel]

    Hi Aditya,
    
    This is a good question and one where in the end the person
    operating the transmitter is responsible for ensuring that they
    operate legally. Many questions to the mailing list are either
    explicitly or possibly related to wireless communications systems
    and GNU Radio gets used frequently for research and work on testing
    and improving the security of those systems. It is impossible for
    people answering questions to know for sure that the answers won't
    be used for illegal acts so largely we must hope and trust that the
    vast majority of users are doing so legally.
    
    When it is questionable, like this question, I personally try to ask
    about the application and precautions made to keep the system legal.
    I'm not capable of knowing all the laws and requirements of all
    countries or responsible for doing so, but if someone starts talking
    about RF shield enclosures and/or can link to a company or group
    with a plausible reason for doing wireless work involving testing
    jamming or running their own cellular basestation for instance then
    I feel better answering questions.
    
    GNU Radio and SDRs are tools and it is worth everyone being aware
    that it is likely used by a very small number of people for illegal
    acts. People responding to questions do so on their own best
    judgement and collectively as a community I feel confident that we
    find a good balance.
    
    Derek

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!
