APPENDIX E: RF EXPOSURE
FCC
FCC Regulations allow up to 36 dBm effective radiated power (ERP). Therefore, the sum of the transmitted power
(in dBm), the cabling loss and antenna gain cannot exceed 36 dBm.
Ø
1mW = 0 dBm
Ø
10 mW = 10 dBm
Ø
100 mW = 20 dBm
Ø
1000 mW = 30 dBm
When transmitting 1 Watt (30 dBm) and the cable and connector losses are 2 dB, the antenna gain cannot exceed
36 - (-2) - 30 = 8 dBi.
If an antenna with a gain higher than 8 dBi were to be used, the power setting must be adjusted accordingly.
