Many of the basic techniques of cellular telephony emerged from the design of such systems; for example, techniques such as frequency reuse management, cell sectorization, power control, and handover management.

Overview

One of the main ideas developed in this chapter is that of spatial reuse by partitioning the available FDM carriers into reuse groups, and then allocating these reuse groups to cells in such a way that cochannel interference is within acceptable limits. It is shown that the cochannel ...
