Accepted Answer

Long distance communication between two points on earth is achieved by sky wave communication.

Range of frequencies allotted for mobile to base station communication is 896 to 901 MHz.

Range of frequencies allotted for commercial FM radio broadcast is 88 to 108 MHz.

In amplitude modulation, 50% of the power is present in carrier wave and the other two sidebands carry only 33% of the power.
