Ars Technica reports that in an effort to better understand, and possibly eradicate Wi-Fi dead zones, one man took the hard way by solving the Helmholtz equation for his flat (apartment).
The Helmholtz equation models "the propagation of electronic waves" that involves using a sparse matrix to help minimize the amount of calculation a computer has to do in order to figure out the paths and interferences of waves, in this case from a Wi-Fi router. The whole process is similar to how scattered granular material, like rice or salt, will form complex patterns on top of a speaker depending on where the sound waves are hitting the surfaces.

We have what you might call a wireless mesh in our house, but for some reason the AP with the internet connection is in the kitchen cupboard, very close to the fridge. Powerline ethernet won't work and there's all kinds of problems preventing us from getting a decent line of sight for the wifi or laying some cable.
Anyway. 'N is self tuning to the reflections (that's what those CSIRO patents are about). If only/mostly clients on the good side of the fridge are accessing it the throughput does increase, but it will go out of tune with stuff on the bad side.
