This helps reduce +cell congestion in busy environments. + +In this example, the trx starts with 5dBm output power which increases by 1dB +every two seconds until it reaches nominal power. +Power ramping can use the power-ramp commands at the CONFIG TRX node of the +OsmoBTS VTY. + +.Example: Configure power ramping on trx 0 +---- +OsmoBTS> enable +OsmoBTS# configure terminal +OsmoBTS(config)# bts +OsmoBTS(bts)# trx 0 +OsmoBTS(trx)# power-ramp max-initial 5 dBm +OsmoBTS(trx)# power-ramp step-size 1 dB +OsmoBTS(trx)# power-ramp step-interval 2 +OsmoBTS(trx)# write <1> +---- +<1> the `write` command will make the configuration persistent in the +configuration file. + +De-activating power-ramping can be performed by setting the max-initial value +to the nominal power.
