OsmoTRX is a software-defined radio transceiver that implements the Layer 1
 | 
			
		||||
physical layer of a BTS comprising the following 3GPP specifications:
 | 
			
		||||
 | 
			
		||||
* TS 05.01 *Physical layer on the radio path*
 | 
			
		||||
* TS 05.02 *Multiplexing and Multiple Access on the Radio Path*
 | 
			
		||||
* TS 05.04 *Modulation*
 | 
			
		||||
* TS 05.10 *Radio subsystem synchronization*
 | 
			
		||||
* TS 05.01 "Physical layer on the radio path"
 | 
			
		||||
* TS 05.02 "Multiplexing and Multiple Access on the Radio Path"

		||||
* TS 05.04 "Modulation"
 | 
			
		||||
* TS 05.10 "Radio subsystem synchronization"
 | 
			
		||||

OsmoTRX is originally based on the transceiver code from the

		||||
OsmoTRX is based on the transceiver code from the
 | 
			
		||||
[OpenBTS](https://osmocom.org/projects/osmobts/wiki/OpenBTS) project, but setup
 | 
			
		||||
to operate independently with the purpose of using with non-OpenBTS software and
 | 
			
		||||
projects, specifically within the Osmocom stack.  Used together with
 | 
			
		||||
[OsmoBTS](https://osmocom.org/projects/osmobts/wiki) you can get a pretty
 | 
			
		||||
standard GSM/GPRS/EGPRS BTS with Abis interface as per the relevant 3GPP specifications.
 | 
			
		||||
projects, while still maintaining backwards compatibility with OpenBTS when
 | 
			
		||||
possible. Currently there are numerous features contained in OsmoTRX that extend
 | 
			
		||||
the functionality of the OpenBTS transceiver. These features include enhanced
 | 
			
		||||
support for various embedded platforms - notably ARM - and dual channel
 | 
			
		||||
diversity support for the Fairwaves umtrx.
