The goal of this thesis is the development of traffic engineering rules for cellular packet
radio networks based on GPRS and EDGE. They are based on traffic models for typical
mobile applications. Load generators, representing these traffic models, are developed
and integrated into a simulation environment with the prototypical implementation of
the EGPRS protocols and models for the radio channel, which were also developed in
the framework of this thesis. With this simulation tool a comprehensive performance
evaluation is carried out that leads to the traffic engineering rules.
The idea of the book was born during the time when the second generation cellular system was looming on the horizon.At that time ,the world was divided into three distinct camps as far as looking for a standard: Europe North America and Japan.
Transmit power in wireless cellular networks is a key degree of freedom
in the management of interference, energy, and connectivity. Power
control in both uplink and downlink of a cellular network has been
extensively studied, especially over the last 15 years, and some of the
results have enabled the continuous evolution and significant impact of
the digital cellular technology.
The market for cellular phones and wireless data transmission equipment has changed
dramatically since the late 1970s when cellular phones were first introduced and the
late 1980s when wireless data equipment became available. As would be expected,
duringthistime RF test requirements and RF test equipment has changed dramatically.
