What does AMTS mean in MOBILE

Functionality

AMTS operates on the analog Frequency Division Multiple Access (FDMA) technology, which divides the available radio spectrum into narrowband channels. Each channel is assigned to a specific user, allowing multiple users to share the same frequency band simultaneously. This architecture enabled AMTS networks to support a limited number of concurrent calls within a given coverage area.

Features

• Analog Signal Transmission: AMTS utilizes analog signals for voice communication, which are more susceptible to interference and noise compared to digital signals.
• Limited Capacity: AMTS networks had a relatively low capacity, with a limited number of available channels and a limited range of frequencies.
• Roaming: AMTS supported roaming, allowing users to access the network outside their home coverage area.
• Voice-Only Communication: AMTS was primarily designed for voice communication, with limited support for data transmission.

Impact and Legacy

Despite its limitations, AMTS played a pivotal role in the development of cellular communications. It introduced essential concepts such as network handovers, call encryption, and subscriber identification, which became fundamental to later cellular technologies. AMTS laid the groundwork for the more advanced digital cellular systems that followed, such as GSM and CDMA.
