Presumably "only" when CellID detection change; more specifically, an optimization could be that having determined that the user is in a given cell (far from the destination), there is no point in checking again until the user gets into a new cell (even if there are e.g. multiple Wifi networks change along the way). Since cells can get get pretty large, this can be a significant battery/network optimization. Dom
