Configuration Guide

The first challenge in setting up a cellular network is to actually know what you
want to setup and which components you need to achieve that.

2G Networks

Radio Equipment

There is a multitude of BTS equipment that works with Osmocom to choose from.

Various BTS models actually run Osmocom's OsmoBTS and OsmoPCU software:

Others are "closed" BTS that are nevertheless interoperable with Osmocom's
BSC layer:

Core Network

  • Are you going to plug into a 3rd party MSC, e.g. the "voice" part of a
    mobile operator's core network? Then you will want to use the standalone
    OpenBSC approach.
  • Are you looking for a self-contained complete core network?
    Then the OsmoNITB "Network-In-A-Box" approach is for you.
  • osmo-sip-connector may connect your OsmoNITB to external VoIP services.
  • GPRS and EGPRS data services are provided by, for example, OsmoSGSN and
    OpenGGSN. Operation with a 3rd party SGSN or GGSN are also possible.
  • Osmocom also contains various tools to tunnel GTP, MGCP or A protocols
    through a NAT layer.

3G Networks

Radio Equipment

You will need hNodeB hardware that is capable of talking the Iuh protocol
over IP. This type of 3G cell is also known as small cell or femto-cell.

Sysmocom offers a professional small cell product for these purposes to

We're also working on a lowest-cost femtocell offering strictly limited
to active contributors to the Osmocom projects.

Core Network

As outlined in this article, the Osmocom 3G core network uses OsmoHNBGW to
connect to OsmoCSCN and OsmoSGSN. Furthermore osmo-bsc_mgcp is used to
relay RTP voice streams and OpenGGSN may be used to provide data services.
