About OsmoTRX

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.
