Analysis Report The Equipment Under Test (EUT), is a Breathing Sensor Tag with Bluetooth BLE feature. The EUT operates in a frequency range between 2402MHz and 2480MHz. The EUT is powered 3.7VDC internal rechargeable Li-ion battery and/or USB port (5VDC). Antenna Type: Internal, Integral, wire antenna Peak Antenna Gain: 0dBi 2.4GHz Bluetooth portion: Modulation Type: GFSK Conducted RF power range: -20dBm to 0dBm According to the KDB 447498 D04 Interim General RF Exposure Guidance v01 Based on the Maximum allowed average field strength of production tolerance was 95.2dBμV/m at 3m (0 dBm). Thus, it below calculated field strength according to minimum SAR exclusion threshold level as follows: The worst case of SAR Exclusion Threshold Level at 2.48GHz with distance 5mm: = 2.717mW According to the KDB 412172 D01: EIRP = [(FS*D) ^2*1000 / 30] Calculated Field Strength for 2.717mW is 99.6dBuV/m @3m Since maximum average field strength plus production tolerance < = 99.6dBuV/m @3m and antenna gain is > = 0.0dBi, it is concluded that maximum Conducted Power and Field Strength are well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
