Increase Wifi waves with ... beer cans

Along with the development of information technology, the signal transmission devices are increasingly being cut down the wires and the wireless signal transmission is something that many people care about. However, the simple broadcast devices have quite a small antenna and the orientation is not good so many families now want to have wifi coverage on a house of about 4 floors still have to use the relay devices. (repeater) or use up to 2 broadcast devices.

The problem is quite painful, but the solution is very simple. With only 1 can of soft drink cans and about 10 minutes of processing you can help the wifi wave to travel further and have the ability to orient the main broadcast for wifi.

Prepare

All items are very easy to find and cheap:

- A normal can of beer or soft drink.

- Paper knives.

- Drag.

Proceed

First, disconnect the hook from the lid.

Then clean the cans with water.

Next, use a paper knife to cut the bottom of the can in the red line as shown. Try to avoid crushed shells.

With the lid you also cut the same but not cut off still to stick a piece of about 2 to 3cm near the hole.

And cut a line along the can in the most remote position. then open 2 wings, you will get a very simple homemade one-way Parabolic.

Finally, add 2 pieces of clay or paperboard to the can lid to be placed on the modem side if you feel bad. You can always use 2-sided adhesive tape and paste it directly on the modem face, remember to turn the direction of the parabola to the right side Go the farthest you will see the effect when used.

If you want to play around the 4-storey house, you can put the router on the 1st floor and turn the pan up or put the router on the 4th floor and turn the pan downwards. Ideally, you should put it on the 4th floor because if you set the 1st floor, the wave that should be broadcast on the 1st floor will be caught by parabola and reflected on the top so that the bottom layer near the most modem wave will not be the best.

Have fun with this device.
