In 2016, Osmocom gained initial 3.5G support with osmo-iuh and the Iu interface extensions of our libmsc and OsmoSGSN code. This means you can run your own small open source 3.5G cellular network for SMS, Voice and Data services.
However, the project needs more contributors: Become an active member in the Osmocom development community and get your nano3G femtocell for free.
I'm happy to announce that my company sysmocom hereby issues a call for proposals to the general public. Please describe in a short proposal how you would help us improving the Osmocom project if you were to receive one of those free femtocells.
Details of this proposal can be found at https://sysmocom.de/downloads/accelerate_3g5_cfp.pdf
Please contact mailto:email@example.com in case of any questions.
