Have you ever had a hard time getting a wifi signal to a particular place in your home or church office?
Jason Cole had a similar problem, but since he is a PhD student in physics, he decided to figure out why:
“…he mapped his own apartment and assigned refraction values to the walls, then applied so-called Helmholtz equations to model the electromagnetic waves.”
You can see the results here:
And this is why you can sometimes have a good wifi signal on one side of the room, but not the other. It also shows us that simply moving a wifi router from one side of the room to the other could make all the difference between having a wifi signal in another room or not.
Something worth considering anyway. 🙂
