Our original effort in writing this book was to create a starting point for those in
the business community who did not have a high level of technical expertise but
needed to have some understanding of the technical functions of their information
and communication technologies (ICT) in a corporate e ...
For nearly a hundred years telecommunications provided mainly voice services and very low speed
data (telegraph and telex). With the advent of the Internet, several data services became mainstream
in telecommunications; to the point that voice is becoming an accessory to IP-centric data networks.

This book is a result of the recent rapid advances in two related technologies: com-
munications and computers. Over the past few decades, communication systems
have increased in complexity to the point where system design and performance
analysis can no longer be conducted without a significant lev ...
Wireless means different things to different people. For this book, it refers
to the radio systems that provide point-to-point, point-to-multipoint, and
Earth-space communications over transmission links that propagate outside
buildings through the lower atmosphere. Wireless systems are being built
...
Quality of Service ( QoS ) has always been in a world of its own, but as the technology
has been refi ned and has evolved in recent years, QOS usage has increased to the point
where it is now considered a necessary part of network design and operation. As with
most technologies, large - scale deploy ...
Cognitive radios have become a vital solution that allows sharing of the scarce
frequency spectrum available for wireless systems. It has been demonstrated
that it can be used for future wireless systems as well as integrated into 4G/5G
wireless systems. Although there is a great amount of literatur ...
The book is written for those concerned with the design and performance of satellite

With the advent of IMT-2000, CDMA has emerged at the focal point of
interest in wireless communications. Now it has become impossible to discuss
wireless communications without knowing the CDMA technologies. There are
a number of books readily published on the CDMA technologies, but they are
mostly ...
