Where to put Wi-Fi-router: scientific approach

Displacement of Wi-Fi-router just a few centimeters can significantly improve the quality of the signal at a particular point in space. The main thing - to know where to move.

Taught physics - achieved a good Wi-Fi signal. If you think that Maxwell's equations, which describe electromagnetic field are not needed in everyday life, then you are wrong. For example, Jason Cole, PhD from Imperial College London, not just studying electromagnetic radiation in its particular manifestations, but also uses the knowledge gained at the household level, simultaneously earning a little denezhek.

Popular nowadays routers operate in the 2.4 GHz band. Behavior waves can be accurately modeled by the very Maxwell equations. On the basis of the entered person computer algorithm will calculate everything and present in a visual form, ie in the form here is a heat map.

The warmer the color at a particular point, the better the signal from the router there, and accordingly, the quality of the Internet. If the router in the line of sight and the wave does not interfere with obstacles like walls, the signal will be better. This is obvious to anyone. But there is a peculiar aspect. There is a phenomenon, which is called a standing wave. At this point there is an interference of incident and reflected waves, whereby the signal in this place becomes significantly worse. Yourself you do not define such zones, and Cole developed algorithm takes into account the phenomenon.

In order to make the development more accessible, the scientist put the emulator in the Android-application and put in Google Play.

Appendix noticed authoritative Western technical publications, resulting in the development of the Cole was bought a few hundred times in just a few hours. Judging by the reviews and ratings, the algorithm actually works.

It is enough to reproduce the floor plan and upload it to the app. After specifying the parameters and conditions of the router simulator with high accuracy will map the signal quality in the room.
