Full Answer

Broadcast transmissions are used in broadcasting long, medium and short waves. Many airborne applications involving VHF transmissions use air band radio. This includes ground to air communication. HF radio links use sideband amplitude modulation. Quadrature amplitude modulation is used to transmit a variety of data that includes cellular communication and short-range wireless links such as Wi-Fi. There are advantages and disadvantages of using amplitude modulation. Although it is easy to implement, the signal is not efficient in terms of bandwidth and power use.
