There are currently different methods to define and design your scenario(s) (i.e. your [campus] network):
Data from OpenStreetMap (OSM):
OSM provides building layouts for almost any given area. In addition to a defined height information 3D building data can be derived for free. This includes single walls, rooftops or whole buildings based on a polygon. The result is a good compromise between cost-efficient usage of geodata and prediction results.
Import external data:
Import DXF (AutoCAD) or SHAPE-files into your scenario
Define the data yourself:
Planing a new campus/building/area may include buildings that are not there, yet. Just draw the new elements yourself online in the editor we provide.
Combination of all the above:
Use the existing OSM data and add new (or missing) buildings yourself.

Ray Launcher

The heart and soul of Five Bars is the analytical Ray-Launcher. It handles 3D data and considers transmissions and reflections on the surfaces up to any desired order, diffractions as well as materials.
The penetration from the rays of 3D elements (e.g. walls) between the source (i.e. transmitter or access point) to the respective point or area in the defined scenario (see yellow-ish shades in the map in the right).
The rays that "bounce" off the walls, seen by the transmitter. The reflected rays can again lead to transmission on other walls (see red-ish shades in the map in the right).
Based on models from literatures that are validated by the scientific community the "Berg-Model" can be applied in order to account for diffracted components.
A handful, selected key materials have been included into our database. For example, this includes different types of concrete, glasses, plaster, wood and metal. Different values regarding reflection and transmission coefficients have been taken from the literature for that. These materials can be selected for each element (wall, ceiling) individually or a default may be applied for all elements later when doing the prediction(s).


What TO expect:

  • A user-friendly interface with a simple workflow
  • An easy-to-use editor to define scenarios, place transmitters and add geodata
  • An analytical Ray-Launcher with bleeding-edge algorithms
  • Full 3D support (predictions on multiple heights)
  • 5G, 4G and Wi-Fi coverage predictions
  • Export functionality (predicitions as raster data & transmitter reports (BOM))
  • What NOT TO expect:

  • A full-fledged, detailled interior planning tool (for stadiums, high-rise buildings, etc.)
  • A full-fledged macro planning tool (for planning large-scale areas)
  • Digital terrain model oder clutter data support (focus is on a metropolitan/city level)
  • 2G and 3G support
  • Support for passive components (such as splitter, tapper, etc.)
  • Support for OEM components (only abstract elements are considered)
