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.
