Physicist Jason Cole offered his balanced answer to a very topical question - where is the best place to install a router in an apartment.
To begin with, he familiarized himself in detail with the plan of the proposed dwelling, after which, having determined the refractive index of the walls, using the Helmholtz equation, he modeled the propagation of electromagnetic waves from the router.
On the Almost Looks Like Work blog, Cole describes his tricky math. Initially, he suggested placing the router in the center of the apartment so that there was the strongest Wi-Fi signal everywhere.
However, it is not always possible to place the router right in the center of the living room, so research continued. Cole decided to take into account the absorption coefficient of the concrete walls and achieve perfect reflection, forming a standing wave, which allowed him to calculate the optimal Wi-Fi signal strength.
Finally, he confirmed what everyone already knows about: the further we are from the router, the weaker the signal. However, with the correct location of the router, the signals from its antennas will "reach" the farthest corners of your home.
Not to be unfounded, Cole created an application for Android, with the help of which any router user will find the best place for him.
