In Belgium the lowest part of the "a" domain (4 bands around 5.2 GHz) is restricted for indoor use at 200 mW and allowed for outdoor use at 25 mW. Values are from memory but the principle is still clear in my mind. A typical household external wall is an obstacle of around -10 db, sometimes more.
For info, an attenuation of 9 db lowers the signal from 200 mW to 25 mW.
