Researchers at Dartmouth College have found that a 3D printed form covered in aluminum foil may improve wireless range and boost Wi-Fi security. The project, which usually appeared on Eurekalert, involves putting a reflector on and in regards to Wi-Fi routerâs antennae to form the beam, increasing range plus preventing it from passing to unwanted spaces.
âWith 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,â mentioned Xia Zhou, a Dartmouth associate professor.
In their paper, Zhou and his colleagues tested multiple types of directional antennas and also tested a good âanecdotalâ solution that involved adhering a soda can behind the router to shape the radio dunes towards a target. After a couple of iterations, they were able to create particular shapes to increase Wi-Fi reception within specific rooms. They then created a system called WiPrint that 3D designs the exact shape needed to form the supports for better coverage and protection. Once printed all you have to do is usually cover them in aluminum evade.
The team found that will their reflectors could accurately form Wi-Fi beams to avoid some areas and favor others, thereby raising security and coverage. For example , you can shape your beam to avoid venturing out a window into the street yet be stronger in a room close by.
They havenât yet launched the software but rest assured that your grand daddy was right: aluminum foil plus antennas do mix.
