| According to a report by TechCrunch, researchers at Dartmouth University in the UK found that using aluminum foil to wrap a 3D-printed reflector increases the wireless signal range and enhances Wi-Fi security. Details include: Wi- Fi router around the antenna to place a reflector aggregation signal, to enhance signal strength and prevent the signal to a specific direction of transmission.  "With just $ 35 and a good signal coverage, you can tailor the signal reflector to the experience that thousands of dollars of network equipment can deliver," said Zhou Xia, assistant professor at Dartmouth. Zhou Xia and his colleagues tested various types of directional antennas and tested the widely circulated 'secret recipe' of folk: placing the aluminum coke can behind the router and directing the signal by reflection, after several attempts and refinements, They succeeded in creating differently-shaped reflectors that could amplify Wi-Fi signals in different rooms, and later wrote a program called WiPrint that allows users to manipulate the 3D printer to print the desired shape and then print it out with foil A good reflector is a custom Wi-Fi signal reflector that not only enhances Wi-Fi signals but also enhances network security by adjusting the direction of signal propagation. For example, you can limit Wi-Fi signals to your own room Inside, to prevent neighbors or passers-by rub nets. The research team has not yet released the software, but since the principles and methods have been told, you may wish to give it a try. |
