Each square on the map shows the average download speed for roughly the area the square covers. Beneath the average value we show how many results this average value is based on. When you zoom in, fewer values are displayed. Eventually you get so close that individual measurements become visible.

By clicking on the box in the last zoom level, you can see the date and time of the measurement, operator, speed and whether the measurement was done indoors, outdoors or in a car (as stated by the user at the time of measuring).

The speed map shows over a million measurements, made with smart phones over mobile broadband (3g/4g). Measurements made over wifi are not shown on the map.
