Maximum Permissible Exposure FCC ID: 2ASCB-SMFSDDS2 Applicable Standard According to §1.1307(b), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. Remark: 1)For BT:The maximum output power for antenna is 0.47dBm (1.11mW) at 2441MHz, 5dBi antenna gain(with 3.16 numeric antenna gain.) For WIFI:The maximum output power for antenna is 16.12dBm (40.93mW) at 2437MHz, 5dBi antenna gain(with 3.16 numeric antenna gain.) 2) For mobile or fixed location transmitters, no SAR consideration applied. The minimum separation generally be used is at least 20cm, even if the calculation indicate that the MPE distance would be lesser. For BT:Maximum Permissible Exposure output power= 1.11mW Numeric Antenna gain= 3.16 Substituting the MPE safe distance using d=20cm into above equation. Yields: S=0.000199*P*G Where P=Power in mW G=Numeric antenna gain S=Power density in mW/cm 2 Power density= 0.000698mW/cm 2 For WIFI:Maximum Permissible Exposure output power= 40.93mW Numeric Antenna gain= 3.16 Substituting the MPE safe distance using d=20cm into above equation. Yields: S=0.000199*P*G Where P=Power in mW G=Numeric antenna gain S=Power density in mW/cm 2 Power density= 0.025738mW/cm 2 (For mobile or fixed location transmitters, the maximum power density is 1.0 mW/cm 2 even if the calculation indicates that the power density would be larger.)
