APPENDIX B: 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.
HEALTH CANADA
The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not
emit an RF field in excess of Health Canada limits for the general population; consult Safety Code 6, available
from Health Canada’s website:
