Is there an easy way to change Thread transmit power?

Is it possible to reduce the KW41z transmit power in software?  I would like to test a large thread network in mesh configuration in a room that is  ~75 feet-by-75 feet.  In this size of room, nodes on opposite ends are in range.  There is no easy way to test a true mesh unless I have a really large space.


Is there an easy way to reduce wireless range via a software power setting?


The FRDM-KW41Z users guide says "Programmable output power from -30 dBm to +3.5 dBm...".  Can this be accomplished with software or does it require circuit modifications?  I could not find any documentation on this.


Any other suggestions?
