we're happy to announce the next incarnation of OsmoDevCall. Based on the recent polls, the timing has shifted to every 3rd wednesday of the month.
This time, fixeria will be presenting on MS/BS power control support in OsmoBSC/OsmoBTS.
For those not entirely 3gpp-acronym-savyy: That's how the uplink (phone -> network) and downlink (network -> phone) transmit RF power level is adjusted during an active call in GSM.

We're happy to announce that sysmocom has achieved to obtain funding from Open Technology Fund for a variety of enhancements and improvemnts of the Open Source Cellular Network Infrastructure sphere.
The funded activities are in the following areas:
- Better integration between the Osmocom 2G/3G core network elements and the open5gs 4G EPC (evolved packet core)
- Improving the stability, quality and maturity of the open5gs EPC by implementing functional test suites in TTCN-3
- Establishing interoperability with various base station hardware
- Support three trial deployments in rural Mexico with our partner Rhizomatica
- Organize a series of webinars for security researchers on how to use our tools for furthering their research projects
See also the project description at the OpenTechFund website
We'd like to thank OTF awarding funding to our proposal.
We'd also like to thank Rhizomatica and specifically Peter Bloom for all his help in putting together the proposal.
Osmocom now has an official fediverse account
@osmocom@fosstodon.org
which we will be using to send updates on osmocom project developments, releases, events, etc.
Web interface is available at https://fosstodon.org/@osmocom
We'd like to thank fosstodon.org for providing a Mastodon instance catering to the FOSS community.

We're happy to announce release 0.4.0 of OsmoCBC, the Open Source Cell Broadcast Centre.
The major news for this release (aside from the usual series of bugfixes) is the support of LTE/4G via the so-called 3GPP SBcAP interface. This means that emergency messages can now not only sent to a 2G/GSM cellular network, but also to a 4G/LTE network. The support of 3GPP standardized SBcAP ensures interoperability with a variety of different EPC/MME.
Development of this 4G capability was made possibly by a generous grant of the NLnet foundation
Pre-compiled packages for a variety of GNU/Linux distributions are available as usual via our Latest_Builds
For a full changelog, please see https://gitea.osmocom.org/cellular-infrastructure/osmo-cbc/commit/d5c0b73f00a415d7e95176f6bbf6b043e06b24d8
