{{>toc}}

This page lists a variety of topics that might be interesting for Osmocom developers to look at in terms of future features that might be interesting to investigate from an Osmocom point of view.  The list was created by laforge in February 27, and is the result of going through the list of major changes from 3GPP Rel-4 through Rel-14.
