== Configuring OsmTRX
|
||
|
|
||
|
OsmoTRX will read the configuration at startup time and configure the
|
||
|
transceiver accordingly after validating the configuration.
|
||
|
|
||
|
OsmoTRX can handle several TRX channels, but at least one must be configured in
|
||
|
order to be able to start it successfully. Channels must be present in the
|
||
|
configuration file in incremental order, starting from 0 and be consecutive.
|
||
|
|
||
|
Example configuration files for different devices and setups can be found in
|
||
|
`doc/examples/` in 'osmo-trx' git repository.
|
||
|
|
||
|

<1> Configure the local IP address at the TRX used for the connection against `osmo-bts-trx`.
|
||
|
<2> Specify the IP address of `osmo-bts-trx` to connect to.
|
||
|
<3> Specify the reference base UDP port to use for communication.
|
||
|
<4> Don't enable EDGE support.
|
||
|
<5> Use 4 TX samples per symbol. This is device specific.
|
||
|
<6> Use 4 RX samples per symbol. This is device specific.
|
||
|
<7> Configure the first channel. As no other channels are specified, `osmo-trx` assumes it is using only one channel.
|
||
|
<8> Configure the device to use `BAND1` Tx antenna path from all the available ones (device specific).
|
||
|
<9> Configure the device to use `LNAW` Rx antenna path from all the available ones (device specific).
