OsmoBTS can ramp up the power of its trx over time. This helps reduce
cell congestion in busy environments.
+Some models of OsmoBTS (such as osmo-bts-trx) also support ramping down the
+transmit power over time until finally ceasing broadcast, for instance due to a
+trx becoming administratively locked or due to the whole BTS being gracefully
+shut down. This allows for mobile stations camping on the cell to gradually move
+to other cells in the area once the signal drop is detected.
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
