 h1. 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. 

 h1. 2G Networks 

 h2. 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 on the BTS itself: 

 * [[OpenBSC:sysmoBTS]] models 1002, 1002OD, 1020, 1200, 1100 and 2050 (osmo-bts-sysmo) 
 * [[OsmoTRX:|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]] / sysmoBTS 2100 (osmo-bts-lc15) 

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

 * ip.access [[OpenBSC:NanoBTS]] 
 * Siemens [[OpenBSC:BS11]] 
 * [[OpenBSC:Ericsson RBS]] 

 

 h2. 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. 
 ** Since 2017, Osmocom offers a true *SCCP/M3UA based 3GPP A-over-IP interface*. This is available in the new "osmo-bsc.git":http://git.osmocom.org/osmo-bsc; look for "osmo-bsc" in [[Binary_Packages]] or sysmocom OpenEmbedded feeds (starting from "201705"). 
 ** Originally, Osmocom supported only an *SCCPlite based A-interface*. This is still available in the old "openbsc.git":http://git.osmocom.org/openbsc; in [[Binary_Packages]] or sysmocom OpenEmbedded feeds (starting from "201705"), look for @osmo-bsc-sccplite@. 

 * Are you looking for a self-contained complete core network? 
 ** Since 2017, it is recommended to use [[OsmoHLR:]], [[OsmoMSC:]], [[OsmoSTP:]], [[OsmoBSC:]] and [[OsmoMGW:]]. See the [[Osmocom Network In The Box]] guide. 
 ** Historically, Osmocom offered the [[OsmoNITB:]] "Network-In-The-Box" approach. It is still available, but active development is now focused on the new separate programs, see [[Osmocom Network In The Box]]. programs. To migrate from OsmoNITB to the new separate programs, see the [[OsmoNITB Migration Guide]]. 

 * [[Miscellaneous Projects:osmo-sip-connector]] may connect your OsmoMSC or OsmoNITB to external VoIP services. 

 * GPRS and EGPRS data services are provided by, for example, [[OsmoSGSN:]] and [[OpenGGSN:OsmoGGSN]]. Operation with a 3rd party SGSN or GGSN are also possible. 

 * Osmocom also contains various tools to tunnel GTP, RTP/MGCP or A protocols through a NAT layer: 
 ** osmo-bsc_nat 
 ** osmo-bsc_mgcp 
 ** gtphub 

 

 h1. 3G Networks 

 h2. 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 customers. 

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

 h2. Core Network 

 As outlined in "this article":https://osmocom.org/news/59, 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.
