You can do show ap config 802.11b [AP NAME] and see the power levels for each TX power.

Well look at the ap specific section and the dbm. The highest will be shown and that is TX power of 1. If the max is 20dbm that equals to 100 mw. Every 3dbi is half or double. 23dbm is 200mW and 17 is 50mW.

Thanks,
