Maybe you don’t know how the Wi-Fi signal you use every day is transmitted. It is electromagnetic radiation that propagates through the air. That is the explanation of why sometimes there is Internet in some parts of the house that are far away from the modem and not in others that are closer: the signal is affected by both distance and obstacles, especially walls and electrical appliances.
To extend the range there are amplifying antennas that are made of materials that amplify the signal and transmit it with greater power. Aluminum from cans is one of the materials that are used for this purpose. Therefore, you can increase the range of your modem by recycling an empty can.
This is a very simple project that will help you recycle, it will take you just a few minutes, and it will allow you to enjoy the Internet in that comfortable chair that you couldn’t reach before!
Materials
– Empty soda or beer can
– modem
– Scissors
Process
1. Wash the empty can very well. With a knife or scissors, make a horizontal cut near the bottom, parallel to the base.
2. Inserting the scissors into that cut, remove the base of the can.
3. Then cut it crosswise, as you can see in the image. When you get to the top of the can, cut around the outline, but don’t separate it all the way.
3. Lift the part that covered the opening through which you drink, to make it the support for the antenna.
4. Extend the body of the can to the sides, taking care that it does not come off completely from the top (which will now be the new base). That extended flat surface will be the one that will work as an amplifier.
5. Put your amplifier on the antenna of the modem! You just have to pass the can through the antenna through the hole that the soda comes out of. If you have two antennas, make an amplifier for each one. This device does not have the same power as an amplifier that you can buy in the market, but it will increase the signal compared to the antenna alone.
