This book is an entry-level text on the technology of telecommunications. It has been
crafted with the newcomer in mind. The twenty-one chapters of text have been prepared
for high-school graduates who understand algebra, logarithms, and the basic principles of
electricity such as Ohm’s law. However, it is appreciated that many readers require support
in these areas. Appendices A and B review the essentials of electricity and mathematics
up through logarithms. This material was placed in the appendices so as not to distract
from the main theme, the technology of telecommunication systems. Another Topic that
many in the industry find difficult is the use of decibels and derived units. Appendix C
provides the reader a basic understanding of decibels and their applications. The only
mathematics necessary is an understanding of the powers of ten

ThisbookfocusesontheemergingresearchTopic‘green(energy-efficient)wirelessnetworks’
that has drawn huge attention recently from both academia and industry. This Topic is highly
motivated due to important environmental, financial and quality-of-experience (QoE) consid-
erations.Duetosuchconcerns,varioussolutionshavebeenproposedtoenableefficientenergy
usage in wireless networks, and these approaches are referred to as green wireless communi-
cations and networking. The term ‘green’ emphasizes the environmental dimension of the
proposed solutions. Hence, it is not sufficient to present a cost-effective solution unless it is
eco-friendly.

The goal of this book is to provide a concise but lucid explanation and deriva-
tion of the fundamentals of spread-spectrum communication systems. Although
spread-spectrum communication is a staple Topic in textbooks on digital com-
munication, its treatment is usually cursory, and the subject warrants a more
intensive exposition. Originally adopted in military networks as a means of
ensuring secure communication when confronted with the threats of jamming
and interception, spread-spectrum systems are now the core of commercial ap-
plications such as mobile cellular and satellite communication.

Radio propagation measurements and channel modelling continue to be of fundamental importance
to radio system design. As new technology enables dynamic spectrum access and higher data rates,
radio propagation effects such as shadowing, the presence of multipath and frequency dispersion
are the limiting factors in the design of wireless communication systems. While there are several
books covering the Topic of radio propagation in various frequency bands, there appears to be no
books on radio propagation measurements, which this book addresses at length.

Spread-spectrum communication is a core area within the field of digital
communication. Originally used in military networks as countermeasures against
the threats of jamming and interception, spread-spectrum systems are now widely
used in commercial applications and are part of several wireless and mobile
communication standards. Although spread-spectrum communication is a staple
Topic in textbooks on digital communication, its treatment is usually cursory. This
book is designed to provide a more intensive examination of the subject that is
suitable for graduate students and practicing engineers with a solid background
in the theory of digital communication. As the title indicates, this book stresses
principles rather than specific current or planned systems, which are described in
manyotherbooks.My goal in this bookis to providea concisebut lucidexplanation
of the fundamentals of spread-spectrum systems with an emphasis on theoretical
principles.

Over many years, RF-MEMS have been a hot Topic in research at the technology
and device level. In particular, various kinds of mechanical Si-MEMS resonators
and piezoelectric BAW (bulk acoustic wave) resonators have been developed. The
BAW technology has made its way to commercial products for passive RF filters,
in particular for duplexers in RF transceiver front ends for cellular communica-
tions. Beyond their use in filters, micromachined resonators can also be used in
conjunction with active devices in innovative circuits and architectures.

The world of home automation is an exciting field that has exploded over the past
few years with many new technologies in both the commercial and open source
worlds. This book provides a gateway for those interested in learning more about
this Topic and building their own projects.
With the introduction of the Raspberry Pi computer in 2012, a small and powerful
tool is now available for the home automation enthusiast, programmer, and electronic
hobbyist. It allows them to augment their home with sensors and software.

Since the original publication of Manual 74 in 1991, and the preceding
“Guidelines for Transmission Line Structural Loading” in 1984, the
understanding of structural loadings on transmission line structures has
broadened signifi cantly. However, improvements in computational capa-
bility have enabled the transmission line engineer to more easily deter-
mine structural loadings without properly understanding the parameters
that affect these loads. Many seasoned professionals have expressed
concern for the apparent lack of recent information on the Topic of struc-
tural loadings as new engineers enter this industry. The Committee on
Electrical Transmission Structures is charged with the responsibility to
report, evaluate, and provide loading requirements of transmission struc-
tures. This task committee was therefore formed to update and revise the
1991 manual.

This book is based on a Ph.D. research that has been conducted at the Delft
University of Technology in the Netherlands in collaboration with Dutch Electricity
& Gas Distribution Network Operator, Stedin. This book was written as a result of
wider interest that was shown by different industry groups on this Topic after its
public defence. This inspired the author to modify and publish a practical version
of the research for a greater international audience. Therefore, the content of this
book is intended for a double audience, on the one hand for those interested in the
organisational and management aspects of maintenance.
