The short signal on their mobile phone at home? This small technique can be applied to increase the signal. This may not be effective in areas where there is no signal at all. However, this method has been shown to be effective in areas where there is a slight mobile signal.
Only aluminum foil is needed to increase the intensity of the mobile signal. The aluminum foil sheet should be placed opposite the area where the mobile signal is to be received. Aluminum foil is more attractive to mobile signals. The signals reflected by the aluminum foil capture the mobile phone on the opposite side.
Experiments have shown that this method is effective. It has been found that this method can also be used to extend the WiFi connection of the home to more places.
