This book gives a comprehensive overview of the technologies for the advances of
mobile radio access networks. The topics covered include linear transmitters,
superconducting filters and cryogenic radio frequency (RF) front head, radio over
fiber, software radio base stations, mobile terminal positioning, high speed
downlink packet access (HSDPA), multiple antenna systems such as smart
antennas and multiple input and multiple output (MIMO) systems, orthogonal
frequency division multiplexing (OFDM) systems, IP-based radio access networks
(RAN), autonomic networks, and ubiquitous networks.

I suppose. The first two reasons and probably the most important are my love of flying and
my love of radio engineering. This may sound rather dull but I love flying in any machine be
it balloon, glider, propeller aircraft, microlight through to airline jets and the experience of it.
The more I do it the more I feel I understand it.

According to the statistics of the Federal Communications Commission
(FCC), temporal and geographical variations in the utilization of the as-
signed spectrum range from 15% to 85%. The limited available radio spec-
trum and the inefficiency in spectrum usage necessitate a new commu-
nication paradigm to exploit the existing spectrum dynamically.

This introduction takes a visionary look at ideal cognitive radios (CRs) that inte-
grate advanced software-defined radios (SDR) with CR techniques to arrive at
radios that learn to help their user using computer vision, high-performance
speech understanding, global positioning system (GPS) navigation, sophisticated
adaptive networking, adaptive physical layer radio waveforms, and a wide range
of machine learning processes.

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.

This book is intended for the RF planners, to serve as a practical tool in their daily work
designing indoor radio distribution systems. It is not a complete book about all the deep
aspects and corners of GSM, DCS, UMTS and HSPA networks, or all the core network
systems. It is dedicated to the last 10–70 m of the network, the indoor air interface between
the mobile user and the indoor mobile network.

With this book at your fingertips, you, the reader, and I have something in common. We share
the same interest in mobile radio channels. This area attracted my interest first in autumn 1992
whenImovedfromindustrytoacademiatofindachallengeinmylifeandtopursueascientific
career. Since then, I consider myself as a student of the mobile radio channel who lives for
modelling, analyzing, and simulating them. While the first edition of this book resulted from
my teaching and research activities at the Technical University of Hamburg-Harburg (TUHH),
Germany, the present second edition is entirely an outcome of my work at the University of
Agder, Norway.

Mobile radio networks have risen in prominence over the last few years, primarily by the rise
in popularity of cellular phones. It is important to recognise however that mobile radio
technology fulfils a far wider range of applications that meet the demands of the modern
world. These include the networks that allow police and emergency services to serve the
public, military networks for operations and humanitarian support, and the mobile technol-
ogies that are vital to the safety of aircraft.

Radio propagation measurements and channel modelling continue to be of fundamental importance
to radio system design. As new technology enables dynamic spectrum access and higher data rates,
radio propagation effects such as shadowing, the presence of multipath and frequency dispersion
are the limiting factors in the design of wireless communication systems. While there are several
books covering the topic of radio propagation in various frequency bands, there appears to be no
books on radio propagation measurements, which this book addresses at length.
