Researchers use aluminium foil to improve Wi-Fi speed2017-11-08 15:31 by Daniela
Researchers from Darthmouth University have found a solution for all those users, suffering from slow Wi-Fi speeds. They have revealed a simple trick that can improve wireless signal and even strengthen its security, all for under $40.
Scientists used a 3D-printed "wall" covered with regular aluminium foil, creating a reflector that only costs $35. Even more impressive is that the research paper shows numbers that outperform similar solutions which cost $1000-plus.
"Through this single solution, we address a number of challenges that plague wireless users," said Xia Zhou, an assistant professor of computer science at Dartmouth.
While the device works best with the 3D printed material, as it can more accurately capture and maintain the optimal shape for the desired coverage, the team also says you can create a similar structure using cardboard.
