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 BTS with Abis interface as per the relevant 3GPP specifications.
The official homepage of the project is https://osmocom.org/projects/osmotrx/wiki/OsmoTRX
You can clone from the official osmo-trx.git repository using
git clone git://git.osmocom.org/osmo-trx.git
There is a cgit interface at https://git.osmocom.org/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.
