|OpenVizsla USB tracer/analyzer||
OpenVizsla is a Open Hardware FPGA-based USB analyzer for USB Low-Speed, Full-Speed and High-Speed. Unlike other similar devices on the market, hardware design files are available as well as full source code for the firmware and client software of the device....
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 Clock Generator board, using the Si5351C clock synthesizer to derive up to 8 different clocks from a single clock reference, such as a 10MHz GPS-DO or OCXO.
Various modules for building lab/testing setups using an industry-standard 3U component carrier
UmTRX is a dual-channel wide-band SDR transceiver that is designed to be used with OpenBTS and OsmoBTS GSM base stations. Given its SDR architecture UmTRX can easily be used with many other RF applications, and a combination of FPGA and FPRF (Field-Programmable RF) technology plus the ability to process data on a CPU or a DSP, makes it an extraordinarily flexible platform. See UmTRX....
This is basically a place-holder for everything else that doesn't fit in other places.
|Core testing infrastructure||
Issues that have to do with our core testing infrastructure (TTCN3 issues, docker setup) go here.
Issues specific to one test component should still be filed in the respective projects (e.g. osmo-msc).
|Ericsson RBS 6xxx||
This project is an attempt at an independent set of publicly-available documentation of the Ericsson RBS6xxx family of base station products.
|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. ...
This website is intended to collect information about publicly-known security issues and other bugs of mobile communications systems, with a particular focus on the 3GPP-specified protocol layers of GSM, GPRS, EDGE and WCDMA. We collect informationon issues at any protocol layer and at any of the interfaces, i.e. the Um air interface just as well as A-bis, A, IuB, C or any of the SS7/MAP/TCAP based core network interfaces....
This project targets a C-Language library providing an implementation and interface to manage a Modbus node in a Modbus bus.
This library relies heavily on libosmocore library and it is aimed at being used by applications using that same library.
The Modbus specs can be found here: https://www.modbus.org/specs.php...
Osmocom PCAP utilities, such as a distributed client/server capture architecture. It allows a number of PCAP probes on remote hosts, feeding captured packets to a central host in the network. Each probe can have different capture filters. There are multiple options for the protocol between probe and central host....
Scalable Smalltalk/Pharo SMSC with SMPP input and SMPP and SS7 output.

Research on the Vodafone/Sagem SuperSignal AP 2820V femtocell
OP25 is a not-for-profit project to bring together folks that are interested in implementing APCO P25 using a software-defined radio. Our goal is to build a software-defined analyzer for APCO P25 signals that is available under the GNU Public License (GPL)....
|Open Source IMS Client||
Some exploration and hacking towards putting tother an open source IMS (VoLTE, VoWiFi) client
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)....
Osmocom Call Control. A new, protocol-agnostic way of interfacing call control of various different protocols with each other. Currently used within the osmocom-analog domain and with several endpoints.
|Osmocom Conferences (OsmoDevCon, OsmoCon, OsmoDevCall)||
The Osmcoom [Developer] Conference, an annual event where Osmocom Developers and Users gather
This is about a set of shared C programming libraries the Osmocom project develops+maintains, such as
