According to claims, the foil placed behind the router can improve the Wi-Fi signal. Although many are skeptical about this, some studies show that when applied correctly, this method can have a certain effect.
Medianews.az, referring to Lent.az, reports that according to experts, this idea is actually not new.
Foil has been used for many years to direct radio and television signals because it has the ability to reflect radio waves. Since Wi-Fi operates on the same principle, it is assumed that this method can also be applied here.
An experiment conducted in the USA showed that reflective surfaces can affect the propagation of the signal. According to the research, a reflector shaped correctly can direct the signal in a certain direction and strengthen the connection in a specific part of the room.
During the experiments, it was found that foil does not amplify the signal, it simply changes its direction. This means that in one area, the internet speed and stability may improve, while in another area, it may weaken. In some cases, an increase of up to 50 percent in data transfer speed was observed, but the result greatly depends on the environment and placement.
To apply this method, it is recommended to bend the foil into a "C" shape and place it behind the router. This helps to direct the signal forward and reduces propagation in the back direction. However, it is not possible to cover the device entirely with foil, as this may further weaken the signal.
Experts emphasize that the placement of the foil plays a major role. Even small angle changes can seriously affect the result, so it is necessary to test different options to achieve the best result.
In conclusion, aluminum foil can be used as a simple reflector and in some cases can improve the Wi-Fi signal in a certain direction. However, this method is not considered a universal solution and does not replace more effective methods such as proper router placement and additional equipment.
