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 MIMO and wireless broadband services, the wideband properties (e.g. delay spread, angular spread and impulse response) of the mobile radio channel become more and more important for the network planning.

The environments where these systems are intended to be installed, are ranging from large rural areas (macrocells) down to indoor environments (pico- and femtocells). Hence wave propagation prediction methods are required covering the whole range of macro-, micro-, pico- and femto-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.

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 (in 32 or 64 bit)!


The graphical user interface (GUI) of ProMan runs on all Windows 7/Vista/XP/2000/ platforms and with emulators also on UNIX platforms.

 

Propagation engines with all propagation models of WinProp are also available with DLL interfaces for several indoor and outdoor radio network planning tools.
An integration of the propagation engines via an API into any software tool of the customer is of course also possible (for Windows and Linux operating systems in 32 or 64 bit).
