Thanks.
So ham radio must be super low frequencies to travel across continents. It makes sense.
Have you heard these stories where people can use repeaters like other wireless technologies in a home to ping and create 3d images of everything.
If thats true, outside of extremely controled environments, how practical would that be to apply in every day applications?

Yes it is possible, but it's also impractical. Radar uses higher frequencies the can reflect well off many objects, but it cannot give you a very detailed image of the shape of the objects. The WiFi mapping is the same. It can show you large and simple features of an object or room, but it can't give you a 3D model of a person. If that was possible, the applications for such technology would be used by many industries already. It's just like ground penetrating radar. It can tell you something is down there but it can't tell you exactly what it is. It would be amazing if it could, but the technology is always way behind the imagined possibilities. But...we do already use extremely high frequencies to make detailed 3D images possible. Light can do that and it has very good detail. We use it all the time and no one seems to be afraid of it. :)
Sometimes I switch on the lights in my kitchen and map out the 3d layout of the objects in there to navigate my way to the refrigerator and get a beer.
Cheers and thanks for the science class.
