I've used this tons as a network engineer to plot WiFi points. Who the hell has the floor plan of the house they rent? Refun please, thank you.Ī little difficult for the average person to use. Went to website in discription to create the floorplan and my tablet crashed due to virus attack. Thoght it detect sourrunding area and wifi location. I tried to uninstall and reinstall a couple of times but it only goes to 79%.ĭecent, but could use mesh network support. I bought this app but it will only download up to 79%. Zyxel keenetic ultra has three antennas and very common Thanks for your work.įor some reason I can't request a refund for this particular app, I just got scammedīought it just to support researchers and development of useful software. This helped me to better position my router. Impressive app, and rather cheap for what it does.
This app is not intended as a replacement for existing EM simulation software packages.Īs a 2D approximation including only simple walls it may not accurately model a given floorplan.
Where walls are defined, the relevant refractive indices and loss tangents for 2.4GHz radiation are used. The edges of the image use absorbing boundary conditions as in Mur 1981, IEEE Transactions on Electromagnetic Compatibility. When the simulation is stopped a GIF animation is generated.Īn antenna oscillates at 2.4 GHz. To start recording a simulation click the record 'R' button. Images are saved to internal/external storage and added to the end of the camera roll. To save the simulation output as an image, click Save at any time. Click stop to pause at any time - this saves the simulation progress which can be continued by clicking run again. Select the antenna parameters at the bottom.Ĭhoose what to plot - 'Field' is the instantaneous electric field amplitude, 'Flux' is the time-averaged magnitude of Poynting flux.Ĭlick run and the simulation will begin. Touch the image to set a router location, marked by a red circle. The simulation is limited in speed due to the mobile processor, so try to keep images below approximately 1000x1000 pixels Pixels are mapped to 1 centimetre, so scale the floorplan appropriately. Images will be converted into the correct materials on loading - this may take a few seconds. png file, with empty space marked black and materials marked with colours. An example floorplan is included in the app. This app uses the 2D Finite Difference Time Domain (FDTD) method to solve Maxwell's equation on a Cartesian grid. This app is based on a post 'Helmhurts' at my blog 'Almost Looks Like Work', which was featured on Engadget, Ars Technica, and many other publications: See the app in action in the following video by tech news website The Verge: With this app you can take a floorplan of your house, set the location of a WiFi router, and simulate how the electromagnetic WiFi waves propagate.
