# 1.8 The SEAMCAT community

# 1.8.1 SEAMCAT Technical Group (STG)

The SEAMCAT project is an ongoing <span data-highlighted="true" data-vc="highlighted-text"><span class="_kqswh2mm"><span class="_5pioz8co _189e1dm9 _1il9buyh _19lc184f _d0altlke" data-testid="definition-highlighter">WG</span></span></span> SE (Working Group Spectrum Engineering) activity (Figure 16). The daily maintenance of the project and the SEAMCAT software is entrusted to the ECO. The project is funded by the signatories of the ECO council. The SEAMCAT Technical Group (STG) acts as the supervising committee and source of technical expertise. For further information on STG visit the <span data-highlighted="true" data-vc="highlighted-text"><span class="_kqswh2mm"><span class="_5pioz8co _189e1dm9 _1il9buyh _19lc184f _d0altlke" data-testid="definition-highlighter">CEPT</span></span></span> web page: [http://www.<span data-highlighted="true" data-vc="highlighted-text">cept</span>.org/ecc/groups/ecc/<span data-highlighted="true" data-vc="highlighted-text">wg</span>-se/stg](http://www.cept.org/ecc/groups/ecc/wg-se/stg).

# 1.8.2 SEAMCAT community - more than STG

SEAMCAT allows building customized library of components (systems, antennas etc.) or use those created by someone else. It is possible to use predefined antenna patterns, spectrum emission masks, and propagation models etc. which are available in the SEAMCAT library, so that reuse of scenarios, library items, etc. can be used in new studies. You can join the SEAMCAT community to contribute to this activity.

The SEAMCAT community is a forum where active SEAMCAT users can report feedback on the use and improvement of the tool (see Section [2.22](https://ecowiki.atlassian.net/wiki/spaces/SH/pages/493703 "https://ecowiki.atlassian.net/wiki/spaces/SH/pages/493703")). This includes the members of STG but also users from universities and organisations all around the world. This community has extended itself well beyond the <span data-highlighted="true" data-vc="highlighted-text"><span class="_kqswh2mm"><span class="_5pioz8co _189e1dm9 _1il9buyh _19lc184f _d0altlke" data-testid="definition-highlighter">CEPT</span></span></span> borders as depicted in Figure 17.

It is possible to contribute to the community by sharing workspaces, populating libraries, creating and sharing plugins (EPPs, propagation plugins, etc...) and contribute to <span data-highlighted="true" data-vc="highlighted-text"><span class="_kqswh2mm"><span class="_5pioz8co _189e1dm9 _1il9buyh _19lc184f _d0altlke" data-testid="definition-highlighter">ECC</span></span></span> and <span data-highlighted="true" data-vc="highlighted-text">CEPT</span> reports with SEAMCAT simulations. Any plugins are automatically embedded, so it’s only necessary to share workspaces by email.

The SEAMCAT application is open source and it is available free of charge.
