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.

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).
