    Designing a WiFi signal detector

    wow not one person has any idea :shock: Even if someone knows the theory of how to distinguish between Wi-Fi and other RF frequencies that would be a start!

    Designing a WiFi signal detector

    Well thats not my intention, i solely want to detect Wi-Fi signal coming from a hidden Wi-Fi NAS hard drive. Its a project aimed around the ideas of people using hidden storage devices and accessing them remotely. This is currently a problem for the Police service, trying to find these 'hidden'...

    Designing a WiFi signal detector

    Im not sure if i follow? I just need to build a signal strength indicator for a 2.4GHz RF frequency Is this the wrong way to do it? I have orderd one of the key ring Wi-Fi testers that should be here tomorrow. So i can dismantle and inspect that. Basicaly i would like to understand how these...

    Designing a WiFi signal detector

    Hi, i want to build a Wifi detector (for detecting hiden Wifi connected NAS drives) I think i have a good idea of what to do but would like some guidance. I know thats its basically a RF signal at a frequency of around 2.4GHz or around 5GHz so i will need, 1.Recieving antenna. directional? or...
