OsmoTRX is a software-defined radio transceiver that implements the Layer 1 physical layer of a BTS comprising the following 3GPP specifications:
- TS 05.01 Physical layer on the radio path
- TS 05.02 Multiplexing and Multiple Access on the Radio Path
- TS 05.04 Modulation
- TS 05.10 Radio subsystem synchronization
OsmoTRX is originally based on the transceiver code from the OpenBTS project, but setup to operate independently with the purpose of using with non-OpenBTS software and projects, specifically within the Osmocom stack. Used together with OsmoBTS you can get a pretty standard GSM/GPRS/EGPRS BTS with Abis interface as per the relevant 3GPP specifications.

You can clone from the official osmo-trx.git repository using
git clone https://gitea.osmocom.org/cellular-infrastructure/osmo-trx
There is a web interface at https://gitea.osmocom.org/cellular-infrastructure/osmo-trx
Doxygen-generated API documentation is generated during the build process, but also available online for each of the sub-libraries at User Manual for OsmoTRX can be generated during the build process, and is also available online at https://ftp.osmocom.org/docs/latest/osmotrx-usermanual.pdf.
