During the past two decades, technological development related to telecommuni-
cation technologies has allowed organizations of all types and size to be able to de-
velop effective networking applications in support of information management. Fur-
thermore, telecommunication technologies combined with computer technology have
created the foundation of modern information technology which has affected all as-
pects of societal and organizational functions in our modern world.

It is commonly accepted today that optical fiber communications have revolutionized
TELECOMMUNICATIONs. Indeed, dramatic changes have been induced in the way we interact
with our relatives, friends, and colleagues: we retrieve information, we entertain and
educate ourselves, we buy and sell, we organize our activities, and so on, in a long list
of activities. Optical fiber systems initially allowed for a significant curb in the cost of
transmission and later on they sparked the process of a major rethinking regarding some,
generation-old, telecommunication concepts like the (OSI)-layer definition, the lack of
cross-layer dependency, the oversegmentation and overfragmentation of telecommunica-
tions networks, and so on.

The TELECOMMUNICATIONs industry is undoubtedly in a period of radical change with
the advent of mobile broadband radio access and the rapid convergence of Internet
and mobile services. Some of these changes have been enabled by a fundamental
shift in the underlying technologies; mobile networks are now increasingly based
on a pure Internet Protocol (IP) network architecture. Since the first edition of this
book was published in 2009, a multitude of connected devices from eBook readers
to smartphones and even Machine-to-Machine (M2M) technologies have all started
to benefit from mobile broadband. The sea change over the last few years is only the
beginning of a wave of new services that will fundamentally change our economy, our
society, and even our environment. The evolution towards mobile broadband is one of
the core underlying parts of this revolution and is the focus of this book.

The next-generation wireless broadband technology is changing the way
we work, live, learn, and communicate through effective use of state-
of-the-art mobile broadband technology. The packet-data-based revolu-
tion started around 2000 with the introduction of 1x Evolved Data Only
(1xEV-DO) and 1x Evolved Data Voice (1xEV-DV) in 3GPP2 and High
Speed Downlink Packet Access (HSDPA) in 3GPP. The wireless broad-
band fourth-generation technology (4G) is an evolution of the packet-
based 3G system and provides a comprehensive evolution of the
Universal Mobile TELECOMMUNICATIONs System specifications so as to
remain competitive with other broadband systems such as 802.16e
(WiMAX)

This book is intended to help electric power and telephone company
personnel and individuals interested in properly protecting critical tele-
communications circuits and equipment located in high voltage (HV)
environments and to improve service reliability while maintaining safe
working conditions. Critical TELECOMMUNICATIONs circuits are often
located in HV environments such as electric utility power plants,
substations, cell sites on power towers, and standalone telecommuni-
cations facilities such as 911 call centers and mountaintop telecom-
munications sites.

The third generation (3G) mobile communication system is the next big thing
in the world of mobile TELECOMMUNICATIONs. The first generation included
analog mobile phones [e.g., Total Access Communications Systems
(TACS), Nordic Mobile Telephone (NMT), and Advanced Mobile Phone
Service (AMPS)], and the second generation (2G) included digital mobile
phones [e.g., global system for mobile communications (GSM), personal
digital cellular (PDC), and digital AMPS (D-AMPS)]. The 3G will bring
digital multimedia handsets with high data transmission rates, capable of
providing much more than basic voice calls.

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.
Today, high-speed data services are already part of our daily lives at work and at home (web surfing,
e-mail, virtual private networks, VoIP, virtual meetings, chats...). The demand for high-speed data
services will grow even more with the increasing number of people telecommuting.

This books presents the research work of COST 273 Towards Mobile Broadband Multimedia
Networks, hence, it reports on the work performed and on the results achieved within the project
by its participants. The material presented here corresponds to the results obtained in four years
of collaborative work by more than 350 researchers from 137 institutions (universities, operators,
manufacturers, regulators, independent laboratories and others – a full list is provided in Appendix
B) belonging to 29 countries (mainly European, but also from Asia and North America) in the area of
mobileradio. Theobjectiveofpublishingtheseresultsasabookisessentiallytomakethemavailable
to an audience wider than the project. In fact, it just follows a ‘tradition’ of previous COST Actions
in this area of TELECOMMUNICATIONs, i.e. COST 207, 231 and 259.

This is believed to be the first book that takes a view of nanotechnology from a
TELECOMMUNICATIONs and networking perspective. Nanotechnology refers to the manip-
ulation of materials at the atomic or molecular level. Nanotechnology is getting a lot
of attention of late not only in academic settings and in laboratories around the
world, but also in government and venture capitalists’ initiatives. There now is a
major drive to commercialize the technology by all sorts of firms, ranging from start-
ups to Fortune 100 companies.
