FM is more clear in transmission than AM.Its wave length is short whereas the frequency is high and vise verse for AM. Here the frequency is modulated and in AM amplitude is modulated. Natural or human activity like traffic etc doesn't effect the FM transmission whereas AM transmission gets effected.
1. Lesser distortion. Frequency modulated wave is less susceptible to intereferences from buildings, traffic etc which provides improved signal to noise ratio (about 25dB) w.r.t. To man made interference.
2. Waves at higher frequencies can carry more data than the waves at low frequency.
3. Smaller geographical interference between neighboring stations.
4. Less radiated power.
5. Well defined service areas for given transmitter power.
