We review the current applications of photonic technologies to Smart Cities. Inspired
by the Future needs of Smart Cities, we then propose potential applications of advanced
photonic technologies. We find that photonics already has a major impact on Smart
Cities, in terms of smart lighting, sensing, and communication technologies. We further
find that advanced photonic technologies could lead to vastly improved infrastructure,
such as smart water‐supply systems. We conclude by proposing directions for Future
research that will have the greatest impact on realizing Smart City initiatives.

I saw the light of the Future when I first read Ray Kurzweil’s best-seller book The
Singularity Is Near: When Humans Transcend Biology. One cubic inch of nanotube cir-
cuitry, once fully developed, would be up to one hundred million times more powerful
than the human brain.

This book provides technical information about all aspects of 3GPP LTE. The areas
covered range from basic concepts to research-grade material, including Future
directions. The book captures the current state of 3GPP LTE technology and serves
as a source of comprehensive reference material on this subject. It has a total of
12 chapters authored by 50 experts from around the world. The targeted audi-
ence includes professionals who are designers or planners for 3GPP LTE systems,
researchers (faculty members and graduate students), and those who would like to
learn about this field.

The Internet of Things is considered to be the next big opportunity, and challenge, for the
Internet engineering community, users of technology, companies and society as a whole. It
involves connecting embedded devices such as sensors, home appliances, weather stations
and even toys to Internet Protocol (IP) based networks. The number of IP-enabled embedded
devices is increasing rapidly, and although hard to estimate, will surely outnumber the
number of personal computers (PCs) and servers in the Future. With the advances made over
the past decade in microcontroller,low-power radio, battery and microelectronic technology,
the trend in the industry is for smart embedded devices (called smart objects) to become
IP-enabled, and an integral part of the latest services on the Internet. These services are no
longer cyber, just including data created by humans, but are to become very connected to the
physical world around us by including sensor data, the monitoring and control of machines,
and other kinds of physical context. We call this latest frontier of the Internet, consisting of
wireless low-power embedded devices, the Wireless Embedded Internet. Applications that
this new frontier of the Internet enable are critical to the sustainability, efficiency and safety
of society and include home and building automation, healthcare, energy efficiency, smart
grids and environmental monitoring to name just a few.

One traditional view of how wireless networks evolve is of a continuous, inevitable progres-
sion to higher link speeds, combined with greater mobility over wider areas. This standpoint
certainly captures the development from first and second generation cellular systems focused
on voice support, and the early short-range wireless data networks, through to today’s 3G
cellular and mobile broadband systems; there is every confidence that the trend will continue
some way into the Future.

Device-to-device(D2D) communications are now considered as an integral part of Future 5G networks
which will enable direct communication between user equipment (UE) without unnecessary routing via
the network infrastructure. This architecture will result in higher throughputs than conventional cellular
networks, but with the increased potential for co-channel interference induced by randomly located
cellular and D2D UEs.

Emerging technologies such as WiFi and WiMAX are profoundly changing the
landscape of wireless broadband. As we evolve into Future generation wireless
networks, a primary challenge is the support of high data rate, integrated multi-
media type traffic over a unified platform. Due to its inherent advantages in
high-speed communication, orthogonal frequency division multiplexing (OFDM)
has become the modem of choice for a number of high profile wireless systems
(e.g., DVB-T, WiFi, WiMAX, Ultra-wideband).

The capability of radio waves to provide almost instantaneous distant communications
without interconnecting wires was a major factor in the explosive growth of communica-
tions during the 20th century. With the dawn of the 21st century, the Future for communi-
cations systems seems limitless. The invention of the vacuum tube made radio a practical
and affordable communications medium.

How will Future generations refer to our times? Will it be known as one
of space exploration, genetics, atomic energy or computing? Possibly,
but I think it is more likely to be ‘The age of communications’. Not since
printed books and newspapers were first introduced has there been
such an explosion of communication. None of this technology could
function without modern cables and, just as important, competent
installers.

In the preparation of this book, our objective was to provide an advanced understanding of emerging
telecommunications systems, their significance, and the anticipated role these systems will play in the
Future. With the help of our talented associated editors and contributors, we believe we have accomplished
this. By addressing voice, Internet, traffic management, and Future trends, we feel our readers will be
knowledgeable about current and Future telecommunications systems.
