Using Aluminum Foil can Sharpen your Wi-Fi Signal

Many people who think they can increase the signals coming from their Wi-Fi by wrapping aluminum foil around it may not be wrong in their thinking.

Researchers team, led by Dartmouth College, have found that 3D printed signal reflectors which are made of narrow layers of metal and plastic can lead to an improvement of wireless signals.

The trials were on the pattern of employing a soda can behind a router so as to lead the signal in a different direction from obstacles. The researchers made a plastic reflector using a 3D printer. The finishing touches were made by putting an aluminum foil on it.

Many problems are solved using this methodology. It is very economical. Provided you have a 3D printer, you can get the job done for merely $35. Directional antennas have a price tag that is way more than that.

You not only get signals in your room but you can block them elsewhere. This automatically leads to physical safety where any meddling people cannot gain entry to your Wi-Fi system.

The way ahead lies through the designing of reflectors that are made of materials different from 3D printed plastic. Malleable substances are where the future lies for Wi-Fi.

This research was presented on Wednesday, November 8, at ACM's BuildSys 2017 in Delft, Netherlands.
