Resumen de Tinfoil hat keeps your Wi-Fi at home
Wi-Fi signals can sometimes struggle to reach every room in a home--and yet be easy pickings for anyone passing by outside. Now there may be a quick and relatively easy solution. Researchers at Dartmouth College in New Hampshire have developed customized reflectors that sit on routers and precisely control the shape of the Wi-Fi signals they emit. It is already possible to boost a weak signal, but the new tech also allows the signal to be deadened in areas where they don't want it, such as near windows, to help prevent anyone outside snooping on their network.
