Smart Grids provide many benefits for society. Reliability, observability across the
energy distribution system and the exchange of information between devices are just
some of the features that make Smart Grids so attractive. One of the main products of
a Smart Grid is to data. The amount of data available nowadays increases fast and carries
several kinds of information. Smart metres allow engineers to perform multiple
measurements and analyse such data. For example, information about consumption,
power quality and digital protection, among others, can be extracted. However, the main
challenge in extracting information from data arises from the data quality. In fact, many
sectors of the society can benefit from such data. Hence, this information needs to be
properly stored and readily available. In this chapter, we will address the main Concepts
involving Technology Information, Data Mining, Big Data and clustering for deploying
information on Smart Grids.

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.

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.

This work titled A Digital Phase Locked Loop based Signal and Symbol Recovery
System for Wireless Channel is intended to serve as a document covering funda-
mental Concepts and application details related to the design of digital phase locked
loop (DPLL) and its importance in wireless communication. It documents some
of the work done during the last few years covering rudimentary design issues,
complex implementations, and fixing configuration for a range of wireless propa-
gation conditions.

Optical communication technology has been extensively developed over the
last 50 years, since the proposed idea by Kao and Hockham [1]. However, only
during the last 15 years have the Concepts of communication foundation, that
is, the modulation and demodulation techniques, been applied. This is pos-
sible due to processing signals using real and imaginary components in the
baseband in the digital domain. The baseband signals can be recovered from
the optical passband region using polarization and phase diversity tech-
niques, as well as technology that was developed in the mid-1980s.

While teaching classes on digital transmission and mobile communications for
undergraduate and graduate students, I was wondering if it would be possible to
write a book capable of giving them some insight about the practical meaning of the
Concepts, beyond the mathematics; the same insight that experience and repetitive
contact with the subject are capable to construct; the insight that is capable of build-
ing the bridge between the theory and how the theory manifests itself in practice.

The rapid growth in mobile communications has led to an increasing demand for wide-
band high data rate communications services. In recent years, Distributed Antenna
Systems (DAS) has emerged as a promising candidate for future (beyond 3G or 4G)
mobile communications, as illustrated by projects such as FRAMES and FuTURE. The
architecture of DAS inherits and develops the Concepts of pico- or micro-cell systems,
where multiple distributed antennas or access points (AP) are connected to and con-
trolled by a central unit.

Mobile multimedia communication is increasingly in demand because of the basic need to communi-
cate at any time, anywhere, using any technology. In addition, to voice communication, people have a
desire to access a range of other services that comprise multimedia elements—text, image, animation,
high fidelity audio and video using mobile communication networks. To meet these demands, mobile
communication technologies has evolved from analog to digital, and the networks have passed through
a number of generations from first generation (1G) to fourth generation (4G).
