Scientists target Wi-Fi signal with 3D-printed reflector

Scientists this week published research they’ve named WiPrint. This software maps a space and then 3D-prints a reflector with which the WiFi signal can be directed.

The research is a bit older, but that didn’t stop the scientists from presenting it this week. They state that it has been known for some time that Wi-Fi signals can be aimed by, for example, using a cut open can. However, their technique must be a bit more accurate and ensure, for example, that the WiFi signal in a certain room is strengthened or attenuated.

Schematic overview

By entering the layout of one or more rooms into the software, it starts using an algorithm to determine the optimal shape of the reflector. This must then be manufactured with a 3D printer and placed around the antennas of the WiFi router. The user still has to wrap the reflector in reflective material; the scientists recommend the use of aluminum foil for this.

They state that their reflector also works with several wireless access points in the house. Their research has shown that a reflector provides an amplification or an attenuation of the signal of 10 and 6dB respectively. In the future, they want to focus on using bendable materials so that the reflector can adapt to changing conditions. It doesn’t appear that the scientists have made their software available online.
