The two major advantages are the signal takes 1/2 the bandwidth and it allows more of the power to be applied into the narrow band thereby increasing strength.
No they get paid to have their songs played on the radio!!!
it is used for the communication
WARC stands for World Administrative Radio Conference which is organised by the International Telecommunications Union. The conference sets up international agreements on the use of radio frequency bands. One advantage of the 1979 conference was the allocation of new frequency bands for amateur radio use on HF. These bands are 30m, 17m & 12m and are generally referred to as the WARC bands.
Microwaves are radio waves.Most satellites communicate in microwave radio frequency bands.
ZigBee operates in the industrial, scientific and medical (ISM) radio bands: 868 MHz in Europe, 915 MHz in the USA and Australia, and 2.4 GHz in most jurisdictions worldwide.
Fessenden created the radio without wires to transmit messages.
An airwave is a single radio frequency - particularly one which has been artificially generated for human communication.

It provided a means of mass communication throughout the world from a single spot. During the Great War, updates were available through radio as well as entertainment, such as the famous War of the Worlds radio show.

TV broadcast signals are in the VHF & UHF radio bands, shorter than most of the radio bands but longer than the microwave band.
The radio frequency spectrum includes bands such as AM (amplitude modulation), FM (frequency modulation), UHF (ultra high frequency), VHF (very high frequency), and microwave. Each band has specific characteristics and uses for communication purposes.
A song is a single when it is on the radio and played regularly.
It helps make long distance radio communication possible though reflecting the radio waves back at the earth. It also helps keep the earth as a green house effect by not allowing the heat that was stored escape into space.
