Foil Aluminum Assessed Can Fix Wi-Fi Signal

If you ever thought of switching to aluminum foil to divert the Wi-Fi signal in your bad home, you're wrong. Quoted from Engadget, EurekAlert reports, researchers at Dartmouth College have found that 3D printed signal reflectors, comprised of thin layers of metal and plastic, can drastically and cheaply improve the wireless signal around the house.

This experiment is based on the idea of ​​using aluminum soda behind the router to be able to steer the signal away from the annoying walls and other obstructions. The team is able to analyze a space and create a custom reflector that will optimize the WiFi signal in the room.

They then enter data into a custom program called WiPrint that designs the optimal plastic reflector and makes it use a 3D printer. The final step is to close the object in aluminum foil and place it on the router.

This solution solves some problems with WiFi signal. The cost is not expensive. If you have access to a 3D printer, it only costs about 35 US dollars, if compared to directional antennas that cost much more.

It also lets you control WiFi signals. Not only does it ensure you have the signal you need in the room, but it also lets you cut the signal where you do not like it. In addition, it improves physical security, ensuring neighbors can not access your network.

The next step for the team is to look for how to design reflectors made of different materials than 3D printing plastics. The idea is to create objects that can really change shape if the room layout changes. It may not extend the coverage area of ​​your router, but it will ensure that you will get a stronger signal in the area you most desire.
