The surge of mobile data traffic forces network
operators to cope with capacity shortage. The deployment of
small cells in 5G networks is meant to reduce latency, backhaul
traffic and increase radio access capacity. In this context, mobile
edge computing technology will be used to manage dedicated
cache space in the radio access network. Thus, mobile network
operators will be able to provision OTT content providers with
new caching services to enhance the quality of experience of their
customers on the move.

The very title of this book is borrowed from the information theory vocabulary,
and, quite naturally, it is an outline of this theory that will serve as an introduction.
The subject of information theory is the scientific study of communications. To this
end it defines a quantitative measurement of the communicated content, i.e. informa-
tion, and deals with two operations essential for communication techniques: source
coding and channel encoding.

This preface is somewhat different from prefaces found in similar books because it does not
focus so much on the content of the book.We have instead chosen to write a few words about
our own experiences from working with telephony services over Internet Protocol (IP). Here
are our stories.

When digital media is perceived only as a tool to deliver content the potential for
using its affordances to explore meaning is lost. Rather than seeing media only as
an access point, we can view it as a way to enhance the expressiveness of content.
Today blogs, wikis, messaging, mash-ups, and social media (Facebook, Twitter,
YouTube and others) offer authors ways to create narrative meaning that refl ects
our new media culture. We can look to the past for similarities and parallels to
better understand how to use social media as a creative tool with which to
dialogue, collaborate, and create interactive narratives.

This book is exclusively dedicated to WiMAX. The focus of the book is
on the applications of WiMAX networks, with delivery of multimedia
content to wireless and mobile devices being the area of greatest atten-
tion. WiMAX has crossed a number of major milestones in the recent
past.

Mobile wireless communications are in constant evolution due to the continu-
ously increasing requirements and expectations of both users and operators.
Mass multimedia* services have been for a long time expected to generate a large
amount of data traffic in future wireless networks [1]. Mass multimedia services
are, by definition, purposed for many people. In general, it can be distinguished
between the distribution of any popular content over a wide area and the distribu-
tion of location-dependent information in highly populated areas. Representative
examples include the delivery of live video streaming content (like sports compe-
titions, concerts, or news) and file download (multimedia clips, digital newspa-
pers, or software updates).

Mobile operators must continuously pursue cost‐
effective and efficient solutions to meet the high data
demand requirements of their subscribers. Limited spectrum
allocations and non‐contiguous spectrum blocks continue
to pose challenges for mobile operators supporting large
data uploads and downloads across their networks. With the
increase in video and social media content, the challenges
have increased exponentially.

The serious study of the practice of how to determine the appropriate content of a
specification is a seldom-appreciated pastime. Those who have the responsibility to
design a product would prefer a greater degree of freedom than permitted by the con-
tent of a specification. Many of those who would manage those who would design
a product would prefer to allocate all of the project funding and schedule to what
they consider more productive labor. These are the attitudes, of course, that doom a
project to defeat but they are hard to counter no matter how many times repeated by
design engineers and managers. A system engineer who has survived a few of these
experiences over a long career may retire and forget the past but we have an endur-
ing obligation to work toward changing these attitudes while trying to offer younger
system engineers a pathway toward a more sure success in requirements analysis and
specification publishing.

In the two years since this book was first published, ultra wideband (UWB) has
advanced and consolidated as a technology, and many more people are aware of the
possibilities for this exciting technology. We too have expanded and consolidated
materials in this second edition in the hope that ‘Ultra Wideband: Signals and Systems
in Communication Engineering’ will continue to prove a useful tool for many students
and engineers to come to an understanding of the basic technologies for UWB.
