Prediction of Wavepropagation

Pathloss and Wideband Properties

Introduction

  


For the installation of mobile radio systems, wave propagation models are necessary to determine the propagation characteristics. The path loss predictions are required for the coverage planning, the determination of multipath effects as well as for interference and cell calculations, which are the basis for the high-level network planning process.

Generally this planning process includes the prediction of the received power in order to determine the parameter sets of the base transceiver stations (or access points). With the introduction of wireless broadband services in third generation systems (UMTS) or in Wireless Local Area Networks (W-LAN), the wideband properties (e.g. delay spread, angular spread and impulse response) of the mobile radio channel become more and more important for the planning process.

The environments where these systems are intended to be installed, are ranging from large rural areas (macrocells) down to indoor environments (picocells). Hence wave propagation prediction methods are required covering the whole range of macro-, micro- and pico-cells including in-building scenarios and situations in special environments like tunnels or along highways.

Predicted Results

  


The ProMan software package is designed to predict the important parameters of the mobile radio channel:

  • Field strength / Power / Path loss

  • Delay spread / Delay window / ....

  • Channel impulse response (CIR)

  • Direction of arrival (DoA) at MS and BS incl. phase information

  • Propagation Paths

ProMan includes a convenient interface to generate the projects and to supervise the computation (online display output during computation). It also offers a huge number of postprocessing features (filter, zoom,...) to edit the predicted results.

 

An example of a prediction result: Directional Channel Impulse Response.

Products: DLL and GUI

 


All prediction models are either integrated in the GUI of ProMan or available as modules or plug-ins for all common operating systems and platforms!


The graphical user interface (GUI) of ProMan runs on all Windows� XP/2000/NT4/ME/98/95� and with emulators also on UNIX� platforms.

 

Propagation models are also available with DLL interface for several radio network planning tools.
