AMPS (Advanced Mobile Phone Service) Coverage

Please consult your eAccess representative for exact coverage in your area.

Description
Advanced Mobile Phone Service is an analog system that was first deployed in 1984.  To send data a modem is required on both ends creating a “circuit” connection.  The geographical area is divided into adjacent, non-overlapping, hexagonal-shaped "cells."  Each cell has its own transmitter and receiver (called a base station) to communicate with the mobile units in that cell; a mobile switching station coordinates the handoff of mobile units crossing cell boundaries.  Portions of the radio spectrum are reused, greatly expanding system capacity but also increasing infrastructure complexity and cost. 
* AMPS is the only ubiquitous standard for North America 
* Most digital cellular phones have AMPS fallback mode
