This book addresses two aspects of network operation quality; namely, resource
management and fault management.
Network operation quality is among the functions to be fulfilled in order to offer
quality of service, QoS, to the end user. It is characterized by four parameters:
– packet loss;
– dela ...
Nature is seldom kind. One of the most appealing uses for radio-
telephone systems—communication with people on the move—must over-
come radio transmission problems so difficult they challenge the imagina-
tion. A microwave radio signal transmitted between a fixed base station
and a moving vehicle ...
Microwave radio network design is a subset of activities that constitute
the overall transmission network design. Transmission networks are
sometimes called transport networks, access networks, or connectivity
networks. For many wireless carriers, microwave is becoming a popu-
lar preference over wi ...
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 net ...
The last decade proved to be hugely successful for the mobile communications industry,
characterised by continued and rapid growth in demand, spurred on by new technological
advances and innovative marketing techniques. Of course, when we refer to mobile commu-
nications, we tend to implicitly refer ...
The growth of mobile technologies is remarkable. At a recent Mobile World Congress Conference, Eric
Schmidt, CEO of Google predicted that within three years, smart phones will surpass Personal Com-
puter sales. The number of mobile phones used worldwide has exceeded 4.6 billion with continued
growth ...
Multi-carrier modulation‚ Orthogonal Frequency Division Multi-
plexing (OFDM) particularly‚ has been successfully applied to
a wide variety of digital communications applications over the past
several years. Although OFDM has been chosen as the physical layer
standard for a diversity of important ...
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 multi ...
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 ...
Ever since ancient times, people continuously have devised new techniques and
technologies for communicating their ideas, needs, and desires to others. Thus,
many forms of increasingly complex communication systems have appeared
over the years. The basic motivations behind each new one were to impro ...
