       osmo-trx - SDR transceiver that implements Layer 1 of a GSM BTS


       osmo-trx [options]


       This manual page documents briefly the osmo-trx command.

       osmo-trx  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"

       In this context, BTS is "Base transceiver station". It's the stations that connect  mobile
       phones to the mobile network.

       3GPP  is  the  "3rd  Generation  Partnership  Project"  which is the collaboration between
       different telecommunication associations for developing new generations  of  mobile  phone
       networks. (post-2G/GSM)


       Usually it works well to start osmo-trx without any options.
