AMPS (Analog Mobile Phone System) is an analog mobile phone system used primarily in the United States and Canada from the 1980s to the early 1990s.
AMPS was one of the first standard systems for cell phone communication and played an important role in wireless communication.
AMPS is designed to allow multiple users to talk simultaneously using Frequency Division Multiple Access (FDMA).
This system uses the 800 MHz band and has a channel bandwidth of 30 kHz.
AMPS also improves communication security by providing functions such as channel encryption and caller identification.
However, since AMPS is an analog system, bandwidth is limited, and call quality deteriorates as noise increases.
AMPS has therefore been replaced by 2G digital communications systems.
