Aluminum Foil For WLAN
The team led by Professor Xia Zhou developed a software that can be used to calculate the optimum shape for individual WLAN reflectors.The generated 3D model can then be printed at low cost with 3D printers and covered with aluminum foil. Properly placed on the router antennas, the WLAN signal can be bundled in such a way that it is 6 dB stronger in the desired range. In other directions it is attenuated by about 10 dB, which additionally protects its own access point against intruders.

The team wants to present its results today at the Buildsys conference in the Netherlands .In the future, the research team wants to experiment with other materials that are supposed to enable dynamic shape adaptation. This would make more flexible amplifiers possible, which can be easily adapted by changing the room with the WLAN router, repositioning it or putting up new furniture. Even without an aluminum amplifier, however, you can get much more out of your home Wi-Fi hotspot with a few adjustments.
