osmobts-trx(1) Base Transceiver Station for GSM


osmobts-trx [options]


OsmoBTS is a software implementation of Layer2/3 of a BTS. It implements the following protocols/interfaces:
  • LAPDm (GSM 04.06)
  • RTP
  • A-bis/IP in IPA multiplex
  • OML (GSM TS 12.21)
  • RSL (GSM TS 08.58)

OsmoBTS is modular and has support for multiple back-ends. A back-end talks to a specific L1/PHY implementation of the respective BTS hardware. Based on this architecture, it should be relatively easy to add a new back-end to support so-far unsupported GSM PHY/L1 and associated hardware.
