Advanced Mobile Phone Service: The Cellular Concept

Abstract

This paper shows how a cellular system operating within a limited block of frequency spectrum can meet the objectives of a large-scale mobile-telephone service designed with attention to cost restraint. It explores the key elements of the cellular concept — frequency reuse and cell splitting — and describes certain mathematical properties of hexagonal cellular geometry. A description of the basic structure and features of amps shows how the cellular concept can be put into practice.
