Simpar is an interactive tool designed for planning and optimizing TV/FM broadcasting networks.

Simpar has been developped for RAI Radiotelevisione Italiana Spa the italian TV/Radio Broadcasting public network.

Simpar implements in a new and powerful way the models for estimating the radio electrical field distribution and cross interferences.

The electrical field is computed taking in account several propagation models: diffraction, troposcattering, super-refraction and tropospheric ducting over the sea.

To estimate the diffraction loss Simpar may use a DTM with neither limits of extension nor resolution: currently for italian territory has been used a model with a land pixel sized about 230m.

Simpar may import several DTM formats including GTOPO30 and DTED format.

Simpar may evaluate cross-interference computing Signal/Interference Ratio maps. 

Simpar has a powerful built-in GIS-like visualization  engine.

Terrain profiles.

Optical view areas.

Coverage areas.

Advanced functions:

Cross-interference evaluation (Signal/Interference Ratio) areas.

Spectral statistics.

Quality areas (per network combination of S/I areas).

Reports and statistics (Coverage maps in terms of territory and population percentage, interference statistics).
