Introduction
This book does not examine the complex and numerous radiofrequency (RF) issues involved
in designing any wireless communications network. In particular, we do not present those
issues related to cellular networks where different antennae of the same network operate and
cooperate in close proximity to each other, with many concomitant problems relating to fre-
quency reuse, interference, fading, and a host of other RF-specific concerns. There are previ-
