# WiFi Solver > WiFi solver is a web-based tool for simulating WiFi signals in a house or other building, to help understand why signal strength might be poor. WiFi solver is different to other simulation tools because: - It runs entirely on the customer's computer, using their GPU - It is highly optimised to run quickly - It simulates at a very low level, solving Maxwell's equations directly - It is very cheap - Is is highly visual and interactive ## Docs - [Application documentation](https://help.wifi-solver.com): All of the features of the application, and how to use them. ## Examples - [A simulation of a house](https://wifi-solver.com/simulator/sim_aa4c7625-2077-487a-9426-00e33174edfc#house) - [A simulation of a waveguide](https://wifi-solver.com/simulator/sim_88b76f33-a7ba-4e57-8913-c8fd486934a8)
