Can Aluminum Foil Boost Wifi Signal?

A simple household product, aluminum foil, has been used for decades to try and increase signals on TV and other electronics. But will it work on your router?
Many people in the past have stated that it does and it could help improve the signal and speeds that are reaching a certain device. These people were called crazy up until about 2017. This was when a team of specialists put this legend to the test. They had not only shown that it does improve the single, but they also found a way to make it work for any space indoors.

Boosted Signal

When looking online for devices people have used to boost their WIFI signal that is made out of aluminum, you are going to find some pretty weird and out there contraptions. For many years people have been trying to rig different contraptions using aluminum foil to help boost their internet speeds and the signal. Some people have created small satellite dishes and others have used unrolled soda cans. When this has been done in the past many people have noticed a huge difference where others have noticed minimal differences.
While many people claim that the theory is ridiculous but if you really think about it, it is not that far off of a serious theory. If you think about it, a WIFI signal is a type of radio wave. However, unlike the radio it is not being used to play audio, it is being used to encode the material on the internet. Keep in mind that using a WIFI router is going to only give you about 150 feet of internet. This is without any blockages. Building materials will make the signal weak or non-existent. Metal and concrete easily absorb or block wireless internet signals. However, using foil or cans to help reflect a signal which will possibly help to avoid dead zones.

The Science

There was a team of expert researchers that were located at Dartmouth University. This group of people tried the can trick because they wanted to see if it worked and if there was any way they could enhance or improve the do-it-yourself design.
First, they wrote what is known as an algorithm. Then, they plugged in all the data and what they wanted to target. This in return allowed them to create a reflector that they could print using a 3D printer. This reflector was made of plastic and a layer of thin metal. The team then covered the plastic of the device in aluminum foil. They found that this prototype had helped successfully boost their WIFI strength.
