carriers it is necessary to de-rate their power level. For FM carriers, they need to be
de-rated as shown...
Number of Carriers Power per Carrier
1 +37 dBm
2 +26 dBm
3 +24 dBm
4 +22 dBm
5 +20 dBm
6 +19 dBm
7 +18 dBm

9 +16 dBm
10 +15 dBm
15 +13 dBm

For complex CDMA, TDMA, GSM, etc. carriers, typically de-rate by a further 3 to 5
