= OsmoBTS =

OsmoBTS is a software part of a BTS, which implements Layer 1, Layer 2 and Layer 3: * LAPDm (GSM 04.06) * RTP * A-bis/IP (similar to ip.access nanoBTS) * OML (GSM 12.21) * RSL (GSM 08.58)

OsmoBTS is building up on work done previosuly for [wiki:OpenBSC] (RSL, OML, RTP) and [http://bb.osmocom.org OsmocomBB] (LAPDm). A-bis/IP implementation is heavily inspired by ip.access nanoBTS A-bis/IP implementation.

OsmoBTS is written in a re-targettable way, i.e. it should be relatively easy to target a new BTS hardware (i.e. BTS-side Layer 0 or Layer 1) with it.

Hardware support

So far OsmoBTS supports a number of hardware options: * Quad-band femto-BTS product called [http://www.sysmocom.de/products/sysmobts sysmoBTS] which is sold by [http://sysmocom.de/ sysmocom] * Wideband SDR transceiver hardware [https://code.google.com/p/umtrx/ UmTRX] sold by [https://fairwaves.ru fairwaves] and a number of other SDR transceivers, using OpenBTS transceiver software. * A pretty crazy experimental BTS hardware based on two OsmocomBB phones had originally been supported, but needs to be re-integrated with core code changes.

Check out [wiki:network_from_scratch] page for more information how to run OsmoBTS with UmTRX (using the OpenBTS transceiver software) or OsmocomBB phones.

Status

The source code includes a http://cgit.osmocom.org/cgit/osmo-bts/tree/README file with current status information

GPRS support

osmo-bts has recently been extended with a socket interface towards [wiki:osmo-pcu]. This adds GPRS (and later EDGE) support to it.

Source code

The source code is available from git.osmocom.org (module osmo-bts).

Public read-only access is available via
git clone git://git.osmocom.org/osmo-bts
You can browse it via cgit: http://cgit.osmocom.org/cgit/osmo-bts/
