I checked the dutch regulations and I see:
5150 – 5250 MHz
200 mW e.i.r.p. 10mW/MHz vermogensdichtheid (indoor)
5250 – 5350 MHz
200 mW e.i.r.p. 10 mW/MHz vermogensdichtheid (indoor)
5470 – 5725 MHz
1 W e.i.r.p. 50 mW/MHz vermogensdichtheid (outdoor)
2400 – 2483,5 MHz (no in or outdoor restriction, i think)
100 mW e.i.r.p. en 100 mW/100 kHz
