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.

Following chapter introduces the mobile communication, gives a short history of wireless
communication evolution, and highlights some application scenarios predestined for the
use of mobile devices. Cellular and wireless based systems related to different generations
of mobile communication, including GSM, IS-95, PHS, AMPS, D-AMPS, cdma2000 and
WCDMA are also described by this chapter. Much attention in this chapter is given
to express the wireless based networks, such as Wi-Fi and WiBro/WiMax, and wireless
broadcasting systems, including DMB, DVB-H, and ISDB-T. We conclude the chapter
with the future vision of mobile communication evolution

The objective of this book is to allow the reader to predict the received
signal power produced by a particular radio transmitter. The first two
chapters examine propagation in free space for point-to-point and
point-to-area transmission, respectively. This is combined with a dis-
cussion regarding the characteristics of antennas for various purposes. In
chapter 3, the effect of obstacles, whether buildings or mountains, is
discussed and analytical methods, whereby the strength of a signal is the
shadow of an obstacle can be predicted, are presented.

This book is intended for RF planners, to serve as a practical tool in their daily work
designing indoor radio distribution systems.
Based on feedback from readers of the first edition it was clear to me that I needed to add
more material and in depth description of the basics of indoor systems based on using
repeaters; this has grown into a new Section 4.7.
There was also a strong demand to add more detail and dedicate a full chapter to radio
planning in tunnels, for both rail and road tunnels; and redundancy principles in the design
focus for solving the challenge of handover zones. An entire chapter 11 is now dedicated to
tunnel radio planning.

Your Cisco Networking Academy Course Booklet is designed as a study resource you can easily read, high-
light, and review on the go, wherever the Internet is not available or practical:
■ The text is extracted directly, word-for-word, from the online course so you can highlight important
points and take notes in the “Your chapter Notes” section.
■ Headings with the exact page correlations provide a quick reference to the online course for your class-
room discussions and exam preparation.
■ An icon system directs you to the online curriculum to take full advantage of the images, labs, Packet
Tracer activities, and dynamic Flash-based activities embedded within the Networking Academy online
course interface.

Before delving into the details of orthogonal frequency division multiplexing (OFDM), relevant
background material must be presented first. The purpose of this chapter is to provide the necessary
building blocks for the development of OFDM principles. Included in this chapter are reviews of stochastic
and random process, discrete-time signals and systems, and the Discrete Fourier Transform (DFT). Tooled
with the necessary mathematical foundation, we proceed with an overview of digital communication
systems and OFDM communication systems. We conclude the chapter with summaries of the OFDM
wireless LAN standards currently in existence and a high-level comparison of single carrier systems versus
OFDM.

Performance analysis belongs to the domain of applied mathematics. The
major domain of application in this book concerns telecommunications sys-
tems and networks. We will mainly use stochastic analysis and probability
theory to address problems in the performance evaluation of telecommuni-
cations systems and networks. The first chapter will provide a motivation
and a statement of several problems.
