Researchers have created a cheap way to boost and secure your Wi-Fi network.
"With a simple investment of about $35 and specifying coverage requirements, a wireless reflector can be custom-built to outperform antennae that cost thousands of dollars," said Xia Zhou, an assistant professor of computer science at Dartmouth.
The work builds on past experiments that have used a soda can behind a router's antenna to act as a reflector that boosts bandwidth by targeting a Wi-Fi signal in one direction
