What is Reddit's opinion of WiFi Solver FDTD?

Poti sa verifici pe planul casei cam cum se propaga semnalul cu aplicație in genul WiFi Solver FDTD. Daca ai cablu de retea destul de lung si poti sa muti router-ul in fiecare camera, poti sa masori live puterea semnalului in diferite locatii cu aplicatie de genul Wifi Analyzer

The dev says the app:
> uses the 2D Finite Difference Time Domain method to solve Maxwell's equation on a Cartesian grid

Here's the app: https://play.google.com/store/apps/details?id=com.jasmcole.wifisolver&hl=en

Here you go :)

Sorry, I misunderstood your question.

I thought you were the guy asking why he could be right next to his router getting a weak signal.

If you have an area of your house you want better signal in, then yes, you can move your router somewhere to improve signal.

In theory, there's likely a point somewhere in your house that could generate a strong signal a considerable distance from the router... But without solving the Helmholtz equation for your living space, you'd have to guess where it was.

Fortunately for you, the guy who made this gif made an Android app to do just that.

Upload a PNG of your floorplan following the color coded legend to pick various materials. These stills are all approximately 50 nanoseconds worth of simulated propagation. That's just about how long it took each to reach a steady state.

Top right image is the sim for where I actually have my router. The top right room is my kitchen. Living room is top left. Master bedroom bottom right. Materials in the sim are wood, concrete, and glass.

I use wifi solver to get a decent heat map simulation. I would try for two on each floor.

Once you have a good idea on where to put them do it and you will want something like Wifi Analyzer to verify it in the real world once the AP's have been placed.

This specific gif was made using the Android app WiFi Solver FDTD in which you map your house and it's materials and it slowly generates the images above, and can convert it into a gif.

In fact, the house map in OP is the default test house map in the app.

Hey, I made this app and animation.

Haha, whoops, meant to post the link to the app. Looks like I'm not so good at self promotion :-(
