EDR: Worse case output power is as below: [2441MHz: 3.46dBm] Maximum output power is 3.46dBm (2.22 mW). (2.22mW /5mm)·[√2.441(GHz)]= 0.69<3.0 for 1-g SAR. BLE: Worse case output power is as below: [2480MHz: 2.52dBm] Maximum output power is 2.52dBm (1.79 mW). (1.79mW /5mm)·[√2.480(GHz)]= 0.56<3.0 for 1-g SAR. 2.4G: Worse case output power is as below: [2440MHz: 2.55dBm] Maximum output power is 2.55dBm (1.80 mW). (1.80mW /5mm)·[√2.440(GHz)]= 0.56<3.0 for 1-g SAR. Then SAR evaluation is not required.
