This 3D WiFi mapping device illustrates the finicky nature of wireless signals

  1. Apps like WiFi Analyzer are excellent tools for troubleshooting pesky wireless issues but even still, wouldn't it be much easier (and cooler) if you could visually see what's going on? Thanks to the ingenuity of YouTube user CNLohr, it's now...

    That's like watching someone's brain work - you won't have a clue what you are looking at, even if it is your own brain :)

    The guy more likely mapped out how his body masks out Wi-Fi signals as he runs around the room with that sensor, not what the actual signal strengths are.
  7. And that's why I prefer an ethernet cord

    Very interesting. Surprised no one thought of this before.
    RF can be VERY strange the way it propagates. If you have ever been driving your car, park it in just the right spot, and the signal fades/gets choppy on your car radio, but if you move it 1-2 feet more it gets better, that's the issue. Ham radio operator for over 25 years and when we make signal propagation charts, you'd be surprised how a signal can react, depending on the ground, trees, metal objects, cars parked in the street. RF is like "magic". People know about it, but even after decades, sometimes it is a mystery to me.
