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.
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:
- sysmoBTS (osmo-bts-sysmo)
- SDR based BTSs, e.g. using the Ettus B200 or Fairwaves' UmTRX (osmo-trx plus osmo-bts-trx)
- Octasic OctBTS (osmo-bts-octphy)
- Nutaq Litecell 1.5 (osmo-bts-lc15)
Others are "closed" BTS that are nevertheless interoperable with Osmocom's
- 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
- 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
OsmoGGSN. 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:
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 customers.
We're also working on a lowest-cost femtocell offering strictly limited to active
contributors to the Osmocom projects.
As outlined in this article, the Osmocom 3G core network uses OsmoHNBGW to
connect to OsmoMSC and OsmoSGSN. Furthermore osmo-bsc_mgcp is used to
relay RTP voice streams and OsmoGGSN may be used to provide data services.
