= OsmoTRX =
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"
OsmoTRX is a spinoff project of the OpenBTS transceiver for the purpose of using with non-OpenBTS software and projects.
