Maximum Permissible Exposure Applicable Standard According to §1.1307(b)(5), 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) The maximum output power for antenna is -0.89dBm (0.81mW) at 2402MHz, 0.58 dBi antenna gain(with 1.14 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. Maximum Permissible Exposure output power=0.81mW Numeric Antenna gain=1.14 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/cm2 Power density=0.000184mW/cm2 (For mobile or fixed location transmitters, the maximum power density is 1.0 mW/cm2 even if the calculation indicates that the power density would be larger.) Result: Because the result of power density is lower than the limit, so the device is exempt from SAR.
