Name Description
M.2 (NGFF) WWAN modem USB breakout board

This is a small break-out board for M.2 (NGFF) type cellular / WWAN modems.

It allows you to insert a M.2 modem from any vendor, and it will provide you with:
  • mini USB 3 socket for connection to a USB Host (like your PC/Laptop or Embedded System)
  • 5V DC input for power supply (USB supply usually insufficient for a modem)...
OsmoGSMTester

This is a python-based test framework by which we can control a set of BTSs and Modems to execute full-system end-to-end verification tests. We use this within Osmocom to du full end-to-end testing with all our network elements and real BTS + RF + Modem Hardware....

Osmocom Analog

This is a project implementing the analog cellular systems used in Germany and other countries in the past. It provides base station implementation of A-Netz (German pre-cellular), B-Netz (German pre-cellular), C-Netz (German cellular), NMT (Scandinavian: Nordisk Mobil Telefon) and AMPS/TACS (American: Advanced Mobile Phone Service)....

libosmo-netif

This is a network interfacing library intended to abstract all kinds of signalling + user payload interfaces, including Abis/IP (IPA), A/IP (SCCPlite), as well as the Osmux protocol

Nuttx-bb

This is a more experimental, work-in-progress port of the OsmocomBB Layer1 to the Nuttx RTOS

Cellular Network Infrastructure

This is a group of Osmocom programs implementing cellular network infrastructure components for GSM, GPRS, EDGE, UMTS, HSPA, LTE and their associated interfaces and protocol stacks.

This includes components for classic circuit-switched GSM:...

OsmoHNodeB

This is a first step towards implementing a minimal hNodeB upper layer part, mainly handling HNBAP/RUA/RANAP messages on the Iuh interface. This is not expected to be a full / usable hNodeB anytime soon [if ever].

M.2 (NGFF) WWAN modem + SIM Card emulation board

This is a carrier board for M.2 (NGFF) type cellular / WWAN modems with integrated SIMtrace2.

It allows you to insert a M.2 modem from any vendor, and it will provide you with:
  • mini USB 3 socket for connection to a USB Host (like your PC/Laptop or Embedded System)...
OpenBSC

This is a legacy all-in-one implementation of the Osmocom BSC + MSC + HLR, instead refer to OsmoBSC, OsmoMSC, OsmoHLR.

This is a project aiming to create a Free Software, (A)GPL-licensed software implementations for the GSM/3GPP protocol stacks and elements....

libosmocore

This covers the libosmocore.git repository including libosmocore, libosmogsm, libosmogb, libosmoctrl, libosmocodec, libosmocoding.

OsmoHLR

The Osmocom Home Location Register (OsmoHLR) is the subscriber database and authentication key store of an Osmocom 2G/3G network. It implements the GSUP protocol which is used by OsmoMSC and OsmoSGSN instead of the classic 3GPP TCAP/MAP protocols....

osmo-gbproxy

The Osmocom Gb Proxy is a proxy for the 3GPP Gb interface (between BSS/PCU and SGSN). It allows you to aggregate many Gb links/connections into one. It also has the ability to convert between different Gb interface protocol stacking, such as from Gb-over-FrameRelay to Gb-over-IP....

osmo-clock-conv

The osmo-clock-conv is a small board for low-jitter conversion of a sine clock into a square clock, based around the LTC6957-4.

Osmocom Conferences (OsmoDevCon, OsmoCon, OsmoDevCall)

The Osmcoom [Developer] Conference, an annual event where Osmocom Developers and Users gather

GSM Audio Pocket Knife

The GSM Auido Pocket Knife is a small tool that can encode and decode all of the GSM codecs and can convert between various different frame formats, such as the RTP payload formats, those used by the TI Calypso DSP, the Racal 61x3 testers, etc. You can use it as a RTP sink to play back a RTP stream from OsmoBTS. ...

OsmoDia2GSUP

The Diameter to GSUP (HLR) adapter (OsmoDia2GSUP) enables you to connect osmo-hlr to a 4G MME. It speaks GSUP with osmo-hlr and Diameter/S6a with the MME (hence the name).

Open Source IMS Client

Some exploration and hacking towards putting tother an open source IMS (VoLTE, VoWiFi) client

rtl-sdr

Software project for [ab]using DVB-T USB receivers based on RTL2132 as inexpensive SDR receivers

OsmoSMSC

Scalable Smalltalk/Pharo SMSC with SMPP input and SMPP and SS7 output.

osmo-rfds

RF delay simulator using the ADI Pluto SDR

SuperSignal AP 2820V

Research on the Vodafone/Sagem SuperSignal AP 2820V femtocell

pySim

pySim is a small command-line tool to program(write to) a variety of programmable sim cards.

BBS-Revival

Project about Retro-Communication using BBSs, Modems, DFÜ, Points, etc ...

The goal here is to re-create the modem / bbs / mailbox communication systems of the (late) 1980s and 1990s.

We use the bbs-revival mailing list to coordinate...

Retronetworking

Project about operating ancient, phased-out networking technologies such as TDM, ISDN, PDH, SDH, FDDI, ArcNet, TokenRing and others. The purpose of this is to keep alive the knowledge about the technology, and to be able to present it to interested parties....
