A portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. BLE: Worse case output power is as below: [2440MHz: 5.40dBm] Maximum output power is 5.40dBm (3.47mW). (3.47mW /5mm)·[√2.480(GHz)]= 1.08 <3.0 for 1-g SAR. 2.4G SRD: Worse case output power is as below: [2440MHz: 5.42dBm] Maximum output power is 5.42dBm (3.48mW). (3.48mW /5mm)·[√2.480(GHz)]= 1.09 <3.0 for 1-g SAR. Then SAR evaluation is not required.
