I think you know that power is directly proportional to energy.
E=h*(new);
where new represent frequency of the signals.
so you can say that power is directly proportional to frequency.
.
frequency is inversely proportional to time so and time is directly proportional to distance.
So with low frequency you can travel more distance.
low frequency->more time->>more distance.
