Where should I place the router for the best Wi-Fi signal?

The antenna in the wireless router will emit electromagnetic radiation waves at about 2.4GHz. According to Maxwell's equations, we can deduce the direction of the electromagnetic wave flow, and then by drawing a map, we can make a map containing Wi-Fi signals.

Of course, if you are not good at science, you may still not understand how to know the distribution of signals at home. So a physics doctor named Jason Cole developed a WiFi Solver FDTD mobile app, through which users can clearly see the signal range of their home routers, but it is currently only available for Android systems.

Based on the test, we can also make some suggestions on how to place the router at home.

The most obvious point is that Wi-Fi signals are greatly blocked when passing through walls, so the signal will be best if the router is placed in a straight line from the device.

Sometimes Wi-Fi signals stop propagating and disappear in a corner. This phenomenon is called standing waves. This is because the reflected signal overlaps with it and cancels each other out. These dark spots make the Wi-Fi signal weaker. Therefore, the second point is not so obvious. If the signal reception is poor in one place all the time, it means that it is the standing waves that are causing the problem. Slightly changing the position of the router will change the situation. Even shaking the router will work.

Therefore, when using a router, it is best to surf the Internet around the router and ensure that there are no obstacles blocking it. Finally, do not sit in the corner playing with your mobile phone, as that will be the place with the worst signal in the entire room.
