Researchers led by a team from Dartmouth College have developed an inexpensive device that could finally solve the problem of improving wireless signal strength for indoor spaces with multiple rooms. The same device also greatly improves wireless security.
As Xia Zhou, who is an assistant professor of computer science at Dartmouth College explains, this single solution manages to address some challenges that plague wireless users, including strengthening wireless signals and making them more secure.
It’s important to be able to customize the coverage of wireless networks inside buildings, homes, and offices because this enables users to improve their signal reception in desired areas and weaken it in others. By customizing the coverage, users can increase wireless efficiency through lessening the signal-deadening impact of various building materials.
And that’s exactly what the new device – a 3D reflector – enables users to do. Not only does it help improve wireless efficiency, but it also improves security. “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 Zhou.
According to the team, the new device provides numerous benefits, including great wireless efficiency, strong physical security, ease of use for non-expert users, and low cost.
