WinProp Utilities
The WinProp utilities consist of the Launcher utility and the Updater.
Updater
The feko_update_gui utility and the feko_update utility allows you the flexibility to install an update containing features, minor software enhancements and bug fixes on top of an existing base installation for Altair Feko (which includes Feko and WinProp).
Command Line Update Utility
Use the feko_update utility for scripted updates or updates from a Feko terminal.
Updating From a Local Repository (Command Line)
Download a new software update (or upgrade) from a local repository using the command line utility.

Get Started
The WinProp Getting Started Guide contains step-by-step instructions on how to get started with WinProp.
Examples
The Altair installation directory contains a collection of examples that shows you WinProp concepts and essentials.
Introduction to WinProp
WinProp is a complete suite of tools in the domain of wireless propagation and radio network planning. With applications ranging from satellite to terrestrial, from rural via urban to indoor radio links, WinProp’s innovative wave propagation models combine accuracy with short computation time.
Typical Workflow in WinProp
View the typical workflows when working with propagation simulations in specific scenarios, how to add a network planning to a propagation simulation, include a receiver pattern, set up a time-variant scenario, include multiple-input multiple-output (MIMO) at both the base station and the mobile station, connectivity analysis of sensor networks and optimization.
WallMan
The WallMan component offers a convenient facility to generate and edit vector building databases.
TuMan
The TuMan tool enables you to generate and modify tunnel scenarios.
AMan
Use AMan to generate, edit and analyze a single antenna. Superimpose multiple antennas radiating similar signals to determine the actual antenna pattern while taking into consideration the local environment.
ProMan
The ProMan component includes wave propagation models for different scenarios and network planning simulators for various air interfaces.
Methods
WinProp includes empirical and semi-empirical models (calibration with measurements possible), rigorous 3D ray-tracing models as well as the unique dominant path model (DPM).
Main Applications
In WinProp various air interfaces and applications are pre-defined: broadcasting, cellular, wireless access, WiFi, sensor networks, ICNIRP and EM compliance.
WinProp Utilities
The WinProp utilities consist of the Launcher utility and the Updater.
- Launcher Utility
  The Launcher utility is a single application that allows you quick access to the shortcuts for the Feko components, WinProp components (Microsoft Windows only) and WRAP component (Microsoft Windows only), documentation and Altair license utility. Pin the application to the taskbar for quick launching.
- Updater
  The feko_update_gui utility and the feko_update utility allows you the flexibility to install an update containing features, minor software enhancements and bug fixes on top of an existing base installation for Altair Feko (which includes Feko and WinProp).
  - Version Numbers
    Each major release, upgrade or update is assigned a version number. A version number contains a unique set of numbers assigned to a specific software release for identification purposes. You can determine from the version number if its an initial release, update or upgrade.
  - GUI Update Utility
    Use the feko_update_gui to check for new versions of the software and install an update using a graphical user interface (GUI).
  - Command Line Update Utility
    Use the feko_update utility for scripted updates or updates from a Feko terminal.
    - Updating From a Local Repository (Command Line)
      Download a new software update (or upgrade) from a local repository using the command line utility.
  - Proxy Settings Overview
    The feko_update_gui utility and feko_update utility (GUI and command line) use the system proxy by default, although it may be changed or the use of a proxy suppressed.
  - Creating a Local Update Repository
    Create a local Feko update repository to allow users to update without internet access or to limit the list of update versions that users can use. Local update repositories can also be used to reduce the amount of data being downloaded by downloading a repository once and making it available to many local machines or compute clusters.
Appendix
Reference information is provided in the appendix.

Updating From a Local Repository (Command Line)

Download a new software update (or upgrade) from a local repository using the command line utility.

Open a Feko terminal using the Launcher utility.
Note: If a script is used to call the Feko updater, do one of the following:
- Run the script from a Feko terminal.
- Include %FEKO_HOME%\bin in the PATH environment variable.
- Call the Feko updater using the full path, for example: C:\Program Files\Altair\2025.1\feko\bin\feko_update.exe.
Download the latest version using one of the following workflows:
- To update (if an update is available) within the current minor version, type:
```
feko_update --update-from LOCATION
```
- To upgrade to a new minor version, type:
```
feko_update --upgrade-from LOCATION VERSION
```
where LOCATION is either an absolute file path which can point to an unmapped network share (Windows), mapped (mounted) network share or a directory on a local drive that can contain either extracted archives, multiple zipped archives or a single zipped archive.

The version is the minor version that you would like to upgrade to and would usually be 1, 2 or 3, but it is possible to use latest to upgrade to the latest version.
The command line updater has many options to check for updates without updating or update to the latest version. Use the following command to see a list of options:
```
feko_update --help
```
