The first Third Generation Partnership Project (3GPP) Wideband Code Division
Multiple Access (WCDMA) networks were launched during 2002. By the end of 2005
there were 100 open WCDMA networks and a total of over 150 operators having
frequency licenses for WCDMA operation. Currently, the WCDMA network ...
There are few technologies that have had a more profound effect on people’s lives
than mobile communications. As recently as twenty years ago no one had a mobile
phone, while today 1.4 billion men, women and children depend on them. This now
exceeds the number of landline users, where it took the p ...
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 ...
With the rapid growth of the wireless mobile applications, wireless voice has
begun to challenge wireline voice, whereas the desire to access e-mail, surf the
Web or download music (e.g., MP3) wirelessly is increasing for wireless data.
While second generation (2G) cellular wireless systems, such as ...
Rapid growth of wireless communication services in recent decades has created
a huge demand of radio spectrum. Spectrum scarcity and utilization inefficiency
limit the development of wireless networks. Cognitive radio is a promising tech-
nology that allows secondary users to reuse the underutilized ...
This book stems from its ancestor Digital Transmission Theory,published by
Prentice-Hall in 1987 and now out of print. Following the suggestion of several colleagues who complained about the unavailability of a textbook they liked and adopted in their courses, laying a strong emphasis on ...
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 limit ...
Digital mobile wireless communication and the Internet have undergone a
fantastic growth in the last few years and, despite originating from two different
worlds, they are converging. This convergence corresponds to the evolution of
mobile systems towards the highest broadband data transmissions (GS ...
The following sections profile many of the vendors in the NFV market. The individual profiles were created
through a collaborative effort between SDNCentral’s Research Team and the Vendor’s product experts.
SDNCentral worked under the assumption the information provided by the vendors was factual, ...
Convergence between the two largest networks (Telecom and IP) is taking place
very rapidly and at diff erent levels: (1) network level: unifi cation of IP networks
with traditional Telecom networks through evolving standards (Session Initiation
Protocol (SIP), Realtime Transfer Protocol (RTP), SS7, ...
