-
2G still in demand by lots of use cases (rural, maritime, …)
-
if we had TCAP/MAP interface, many more deployments possible
-
3G has some users but lack of FOSS RNC limits us to femtocells
-
4G is deployed in parallel to 2G in many scenarios
-
Osmocom 2G stack needs 2G-4G integration (SGs, DIAMETER)
-
Osmocom needs to contribute to FOSS 4G projects (nextepc, srsLTE)
-
irony: Now that it’s possible to do properly funded Osmocom development, we have less people involved than in the early days :(
If we don’t manage to focus on 4G soon, interest in 2G will diminish soon
