The Osmocom project is an umbrella project regarding Open Source Mobile Communications. This includes software and tools implementing a variety of mobile communication standards, including GSM, UMTS, DECT, TETRA and many others.

This website is the redmine project management system which we use for
  • Wiki
  • Issues (bugs / features / roadmap)
  • News items

Please select the project you're interested in from our List of Projects - each project then contains its own wiki, issues list, etc.

The best starting point for 2G and 3G core network + BSS is the Cellular Network Infrastructure project's wiki.

Please also see the following other web sites which are not integrated into redmine:

In case you would like to support Osmocom financially, we have set up an opencollective account at https://opencollective.com/osmocom
