You are right, range is an approximation of where the cell might be.

We have a confidence benchmark of 98% - this means we 98% of times, the actual location of device will be within the circle. In a standard API response; there is a 98% chance that the device is at (x,y) or z meters sq around it.

- If we were to reduce our confidence benchmark to 50% - it would mean that 50% of the times, actual location of the device will be within a circle. Because my confidence benchmark is low, I can reduce the accuracy to…say 300 meters. So, there is a 50% chance that the device is at (x,y) or 300 meters sq around it.
- If we were to reduce our confidence benchmark to 10% - it would mean that 10% of the times, actual location of the device will be within a circle. Because my confidence benchmark is low, I can reduce the accuracy to…say 50 meters. So, there is a 10% chance that the device is at (x,y) or 50 meters sq around it.

If we have a higher confidence benchmark, the radius (accuracy value) returned will be larger.
