The first edition of this book was published in 1992. Nine years later it had become
clear that a second edition was required because of the rapidly changing nature of
telecommunication. In 1992, the Internet was in existence but it was not the
household word that it is in the year 2001. Cellular te ...
When 3GPP started standardizing the IMS a few years ago, most analysts expected the

Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor
UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding
the data captured on the links and analysing how the different data segments and messages
are related to each other. In general ...
The use of light to send messages is not new. Fires were used for signaling in

lights have been used to communicate between warships at sea since the days of
Lord Nelson.
The idea of using glass fibre to carry an optica ...
The explosion in demand for wireless services experienced over the past 20 years
has put significant pressure on system designers to increase the capacity of the
systems being deployed. While the spectral resource is very scarce and practically
exhausted, the biggest possibilities are predicted to b ...
Static electricity is the most ancient form of electricity known to humans. More
than 2000 years ago, the Greeks recognized the attraction between certain mate-
rials when they were rubbed together; indeed, the word electricity comes from
the Greek elektron, which means amber. During the seventeenth ...
Electrostatic discharge (ESD) phenomena have been known to mankind since Thales of
Miletus in approximately 600 B.C.E. noticed the attraction of strands of hay to amber.
Two thousand six hundred years have passed and the quest to obtain a better under-
standing of electrostatics and ESD phenomenon c ...
