Why FM is used for short distance communication?

Frequency Modulation (FM) is used for short-distance communication primarily because it offers improved sound quality and resistance to noise and interference compared to amplitude modulation (AM). Its ability to maintain signal integrity over shorter distances makes it ideal for applications like local radio broadcasts, two-way radiOS, and personal communication devices. Additionally, FM's bandwidth allows for a more robust signal, facilitating clearer audio transmission in environments with potential signal disruption.
