With the Wireless module, OPNET can model both terrestrial and satellite radio systems. In this tutorial, you will use Modeler and Wireless modeling to create a radio network you will also observe variations in the quality of received signal that results from radio noise at the receiving node in a dynamic network topology.

The Schumann resonance frequencies are a set of eigenmodes in the extremely low frequency (ELF) portion of the electromagnetic field spectrum. These frequencies are only present for planetary-like bodies with a substantial ionosphere acting as a perfect electric conductor, thus forming a resonance cavity with the surface. In this example, the Schumann resonance frequencies for the Earth are calculated.

WordCloud is a visual depiction of how many times a word is used, or its frequency if you will, within a given set of words. It does this by: reading in plain text, filtering out "stop words", counting how many times a word is used, and displaying results in a Squarified Treemap.

This book provides the reader with the basics in radio engineering, the techniques needed to generate, control, detect, and use radio waves. The text approaches the relevant problems both from the electromagnetic theory based on Maxwell抯 equations and from the circuit theory based on Kirchoff and Ohm抯 laws. Brief introductions to the electromagnetic theory as well as to the circuit theory are provided. Besides passive transmission lines and components, active RF circuits are also addressed.

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.
