The field of telecommunications is becoming ever more complex. In
order to manage the new Telecom industry it is necessary not only
to understand its 3 main components, namely the end users, the
technology and networks, and the business aspects, but also
their vital inter-relationships.
Complexity leads to uncertainty, and one effect of uncertainty is
for people to underestimate the complexity of the business and the
technology. This book takes a holistic approach to the subject and
can be used as a tool for decreasing this uncertainty.
During 2000 many operators paid extremely high sums of money for
3G licenses in a number of European countries, supposing a
potential corresponding and balancing revenue from mobile services
in the new frequency band. Obviously today the licenses are
questionable. Consequently, suppliers and operators were
forced to reduce their international work force.
What are the underlying reasons? Since the true rate and level
of development was hardly foreseen by anyone, the picture is
complex, including factors such as psychology and belief in a new
economy. It is immediately clear that the end user impact has
been severely under-estimated. It is also clear that the
expected development has and is happening, with more speed than
expected, and continues to be complemented with solutions such as
wireless LANs.
This book treats the paradigm shift from a number of angles: user
needs and demands, deregulation of telecom and the convergence
between telecommunications, data communications and the media
industry, the service plan, service implementation, Qo S, and
Security.
Understanding Changing Telecommunications focuses on the
overall principles and context of the new telecommunications world
rather than on high-level technical descriptions in order to aid
the understanding and development of the next generation of telecom
networks. e.g. multimedia over IP and 3G.
