Detailed explanation-1: -Wireless signals are electromagnetic waves travelling through the air. These are formed when electric energy travels through a piece of metal–for example a wire or antenna–and waves are formed around that piece of metal. These waves can travel some distance depending on the strength of that energy.
Detailed explanation-2: -In short, the transmission of data wirelessly is made possible by the manipulation of radio waves. These waves are generated naturally by generating pulses of electricity. These radio waves can then be modified by their amplitude or frequency in order to transmit sound or data.
Detailed explanation-3: -Broadcast radio is a wireless transmission medium that distributes radio signals through the air over long distances such as between cities, regions, and countries and short distances such as within an office or home.
