The 3D scans are the most revealing — you can actually see a 12.5-cm spacing of signal strength, which corresponds to the wavelength of 2.4-GHz WiFi. The video below shows the data capture ...

We already know that it's possible to map your home's WiFi signal in 2D, but that doesn't help if you're holding your phone above your head to get connected. Step forward YouTuber CNLohr, who ...

UW engineers have developed the first 3D-printed plastic objects that can connect to WiFi without electronics. The attachment above can sense when your laundry soap is running low — and ...

Finally, it is applicable to commodity low-end Wi-Fi APs without directional or multiple antennas. The sad part is that, for now, no software is available. The study and results have just been ...

Researchers at the University of Washington have developed a way for 3D-printed plastic objects to transmit information via WiFi without the help of batteries or electronics. And they show that it ...

Researchers with a lab at the University of California, Santa Barbara, used Wi-Fi signals and drones to create 3D maps of the inside of buildings.

If you're interested in building your own 3D WiFi mapping system, CNLohr provides links to all of the information you'll need on his YouTube page.

Researchers from that university have announced the creation of the first 3D printed plastic objects and sensors able to collect useful data and communicate with other WiFi devices on their own.

By sending and receiving Wi-Fi signals, they generated a 3D high-resolution image of the objects inside. And the resulting 3D image was very similar to what was actually inside.

There is also the issue of compatibility, and if these new Wi-Fi 3D chips aren't compatible with previous-generation connections then it could be quite some time before we see them come to market.
