When installing a WiFi router at home that is not too much insulation can reach a wider area, but sometimes there are parts of homes that are not covered by WiFi network because it is blocked by the interior of the house. There are many ways to resolve this issue, such as buying a WiFi extender, creating a WiFi mesh network using a device like Google WiFi, or buying a router with a stronger signal.
But to do so requires more funds, and not all users are willing to spend more funds in order to reach a wider hotspot. Now there is good news, where researchers at Dartmouth College have found a new way that with 3D printing and material costs around $ 35, you can not just fix your WiFi signal, but make it safer at the same time.
This is based on the concept of how to put aluminum foil or aluminum behind the WiFi access point, where it can actually improve the WiFi signal for the better. Of course it can increase the range of hotspots
How does it work? Basically the aluminum will bounce the signal off your router path, so if your WiFi is placed next to the wall, it will bounce the signal off the wall. In addition, by creating physical barriers, it helps limit your wireless signal to a limited space, making it difficult for outside attackers to connect to your network, at least in theory.
The researchers then tested this theory with a 3D printing reflector made of plastic and metal that directs the wireless signal to the areas where you want to reach the area. According to the assistant professor of computer science at Dartmouth, Xia Zhou, “With a simple investment costing around $ 35 and setting coverage requirements, wireless reflectors can be made to outperform antennas that cost thousands of dollars.”
