I was advised here that even though the heat map is a good screening tool, I should still use some kind of Wifi signal strength app to get real life results.
WiFi is a shared resource, every bit of air time is divided between active units.
I've mapped out the floor plan with the UniFi map planner, but I'm not sure how accurate it is or if the colors mean more than signal strength.
Or was a different placement not as good on the map? Same coverage on an 800sqft apartment or a 3000sqft home? I made a virtual copy on SketchUp, but there are plenty of other programs that can do this.
Also consumer routers can often have higher gain antenna that would allow for greater distances.
I just really want to avoid issues when on the edges of the house.
