The ITS Propagation Library (**"PropLib"**) is a collection of open source software developed by [ITS](about.qmd), focused on modeling radio wave propagation under a wide variety of circumstances. The library currently supports C++, .NET, MATLAB®, and Python users through exposing common functionality across multiple programming environments. One of the key benefits of this approach is that users are assured of identical results across languages, allowing researchers to work in their most efficient development environment while benefitting from common library improvements.

## Packages

Currently, PropLib includes implementations of propagation models developed by the U.S. (NTIA/ITS) and by the International Telecommunication Union Radiocommunication Sector (ITU-R). The following are categorized lists of available packages within PropLib. 

### U.S. Propagation Models

Documentation pages are being worked on, and will soon be available through links in the following table, for the following U.S. propagation models:

The listed U.S. propagation models have public code repositories, but
documentation is not yet available on this website. Please check back
later, and contact [code@ntia.gov](mailto:code@ntia.gov) with questions
in the meantime.

### ITU-R Recommendations

The ITU-R Recommendations constitute a set of international technical standards developed by the Radiocommunication Sector (formerly CCIR) of the ITU @itu-r-recommendations. A subset of these have been implemented in software as a part of this library by ITS.
