Researchers from Dartmouth and partner universities developed WiPrint, a low-cost way to shape indoor Wi-Fi coverage using a custom 3D-printed plastic reflector wrapped in ordinary aluminum foil. The
Researchers at Dartmouth College have developed a way to improve and direct Wi‑Fi signals using a 3D-printed reflector covered in aluminum foil. The technique works by exploiting a basic property of e
Researchers and tech experts say aluminum foil behind a Wi‑Fi router can sometimes improve signal, but only in a limited, directional way. A 2017 Dartmouth College study found that a properly curved r
