    The VisualRF page is drawn more accurately when more access points are present.  Anything under 3 or 4 access points that can hear each other would only be only providing a guess and is not really expected to be accurate.  The heat map is typically drawn based on how well access points hear each other vs. how well they should be hearing each other at a specific distance.

    Hi

     

    When we upload floor image to visualRF, it will divided in to more than 2000 grid cell in backend and all cell have same (x,y) measurment value.

     

    VisualRF colors number of grid cell based on transmit power value and singal strenght, if grid cell size is large and -55dbm singal strengh does not reach the corners of the single grid it wont show any color. I checked the heatmap screen shots which you have shared, it looks first floor map grid size is large because of that you are not seeing proper heatmaps.

     

    Note: Make sure while uploading image try provided accurate height/wedith mesausrment values.If image is already uploaded you can set measurments value using resize option.
