Researchers from Dartmouth College and other institutions have developed a low-cost method to manage indoor Wi-Fi coverage using 3D-printed plastic shells wrapped in aluminum foil. This project, called WiPrint, uses software algorithms to simulate radio wave propagation based on specific floor plans, allowing users to redirect signals toward desired areas while minimizing leakage outside the home or into adjacent rooms.
* Increases signal strength by up to 6 decibels in targeted zones and reduces it by as much as 10 decibels in restricted areas.
* Provides a physical layer of privacy that complements digital encryption like WPA2 or WPA3.
* The complete setup is cost-effective, costing approximately $35 to build.
