About OsmTRX

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 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, while still maintaining backwards compatibility with OpenBTS when possible. Currently there are numerous features contained in OsmoTRX that extend the functionality of the OpenBTS transceiver. These features include enhanced support for various embedded platforms - notably ARM - and dual channel diversity support for the Fairwaves umtrx.
