MPE Calculation FCC ID: 2AAIN-BTW218 Remark: Average ≤ Peak, which means that calculating the power density applying Peak power is worst case. The worst case operation mode generating the highest power in each frequency range is taken for calculation. Frequency range:2402-2480MHzTypical use distance: d ≥20cm Power density limit for mobile devices at 2.4 GHz: S ≤1mW/cm 2 Maximum measured conducted power (Peak): Pconducted =-2.92dBm =0.51mW Antenna Gain: G = 0dBi =1on the linear scale Calculation: P radiated = P conducted + G linear =-2.92dBm +0dBi =-2.92dBm =0.51mW Power density S = (P radiated ) / (4π x d 2 ) =0.51/5026 =0.0001mW/cm 2 <1=> below limit Frequency range:5736-5814MHzTypical use distance: d ≥20cm Power density limit for mobile devices at 2.4 GHz: S ≤1mW/cm 2 Maximum measured conducted power (Peak): Pconducted =11.08dBm =12.82mW Antenna Gain: G = 3.2dBi =2.09on the linear scale Calculation: P radiated = P conducted + G linear =11.08dBm +3.2dBi =14.28dBm =26.79mW Power density S = (P radiated ) / (4π x d 2 ) =26.79/5026 =0.0053mW/cm 2 <1=> below limit
