    Hi:

    One way to help prevent those around me from using my wireless router without my permission is to set up a password and encryption.

    However, I'm curious whether I could also ban them based on their geographic locations using ADF and RDF triangulation. Can this be done? RDF/ADF is used to locate a radio signal. Can I prohibit unauthorized access of my wireless network based on the physical location of the enemy trying to use it?


    Thanks,

    GX

    Well if two ADF stations were in use, and you were able to triangulate the rough location of the unauthorized device, I would just go knock on his door.

    Basically you could code custom firmware on your router and an Adruino board. In this case a Linux box acting as your advanced AP to actively control DHCP and iptable rules would work good. Use the pair of ADF's as a trigger to the advanced AP to issue a new IP address and log the Mac ID for future use. Auto firewall or block the IP or even allow traffic and log the .pcap, remember it is your AP.Now if the target device moves you would have to reconfigure the target zone for blocking.

    But remember he can still see all YOUR info or most data which is un-encrypted. That is why you should secure your network among a slew of other reasons... anyone has access to your data in range of your wireless signal.

    To really block the device without traditional means would require directionally RF scrambling his area and may very well be against the law.

    Why not just place a barrier near the devices on the side from which the offending user is located, so your signal never reaches them at all?

    I might be misunderstanding wireless signals, to think that would work. I don't know. At my house, I get my internet beamed to me via wireless. I used to have kind of a dish to receive it with, so I assumed the signal would bounce off of any object made of metal, rather than pass through.

    But.... I could totally be wrong about that.
    Some clocks are only right twice a day, but they are still right when they are right.
