News: sysmocom speakers at OpenCellular workshop

The first African Opencellular workshop will take place from June 19-20 in Nairobi, Kenya. This event is an excellent opportunity to learn about the OpenCellular project within the Telecom Infra Project (TIP), led by Facebook. The Osmocom GSM protocol stack is at the heart of OpenCellular.


sysmocom CEO Harald Welte will give an overview about what you can achieve using the Open Source Osmocom cellular protocol stack and participate in the panel "rural connectivity and open-source: challenges and opportunities". sysmocom develpoer Pau Espin Pedrol will cover the Osmocom end-to-end test framework osmo-gsm-tester.

News: sysmo NITB 3.5G starter kit limited edition

sysmocom announces the availability of a starter kit to enable an easy jump start into testing and developing 3G applications. The well known open NITB has been upgraded to 3G (aka UMTS or WCDMA) network. It now hosts hNodeB-Gateway, MSC/VLR and HLR, SGSN and GGSN but remains a simple "full network in one box" system. This makes the setup of a self-contained 3G network a snap and you can invest the resulting time savings in your research and development work.

About sysmocom

sysmocom fills a gap in the telecommunications market for development, products and services. The existing equipment and service vendors are offering products by large companies to large companies. If you are a small start-up, local/regional MNO or MVNO, you will have found it incredibly difficult to satisfy your needs from the large Telco equipment vendors.

You don't have to have a big budget in order to roll your own GSM network. We have first-hand expertise in the right mixture of Open Source technologies like OpenBSC, OsmoSGSN and OpenGGSN, economic base station technology and off-the-shelf computer hardware to solve your problems.

Even if you are a large operator, we still may have something to offer to you. You are probably used to the fact that your equipment supplier tells you all kinds of things that are allegedly impossible, or require you to buy their next generation hardware even for a minor software feature change. If you have a specific request regarding analysis of your network, or interfacing equipment of different vendors: Talk to us. We will help you to find the best technical and economic solution for your problem, truly independent of any vendor bias.

Our services include

  • custom research and development in mobile communications networks and protocols, from RAN to core network
  • supplying equipment for small MNOs and MVNOs - from SIM cards over core network elements to the BSC, from picocells to small cells to macro-cells.
  • consulting and training services
  • security audits with specific focus on penetration testing of GSM protocols and interfaces
  • protocol tracers, analyzers and converters
  • development of back-haul protocol optimization
  • small GSM networks / network simulation for research, education, training, R&D and factory testing of mobile devices
  • load testing and roaming testing
  • circuit design and software/firmware development of M2M devices using GSM/GPRS/UMTS/LTE modem modules (Wavecom, Cinterion, Option, Simcom, u-blox, Quectel), GPS/GNSS receivers, etc.
  • systems for M2M device testing
  • receivers and simulators for various other radio technology like AIS and ADS-B

We're looking forward to hear from you!
