The energy in a wave is inversely proportional to distance squared. In other words if you double the distance you get one quarter of the power.

For information transfer like wifi this does not matter as long as it’s enough to be detected.

For power transfer this becomes a huge problem quickly because it’s the energy itself that is being transferred.
