FCC ID:BRWDXE IC:6157A-DXE RADIO FREQUENCY EXPOSURE LIMIT Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission's guidelines. See §15.247(b)(4) and §1.1307(b)(1) of this chapter. EUT Specification EUT DXe Transmitter 2.4GHZ Model DXe Transmitter 2.4GHZ Frequency Band (Operating) 2404.0 MHz ~2476.0 MHz □ Portable (<20cm separation) Device Category ■ Mobile (>20cm separation) □ Others □ Occupational/Controlled exposure (S = 5mW/cm2) Exposure Classification ■ General Population/Uncontrolled exposure (S=1mW/cm2) ■ Single antenna □ Multiple antennas Antenna Diversity □ Tx diversity □ Rx diversity □ Tx/Rx diversity Max. Output Power 17.35dBm Antenna Gain (Max) 2.0dBi (Numeric gain:1.58) ■ MPE Evaluation Evaluation Applied □ SAR Evaluation Note: 1. The maximum mix output power is 17.35dBm (54.33mW) with 1 numeric antenna gain. 2. For mobile or fixed location transmitters, no SAR consideration applied. The minimum separation generally be used is at least 20 cm, even if the calculations indicate that the MPE distance would be lesser. TEST RESULT No non-compliance noted.

FCC ID:BRWDXE IC:6157A-DXE Calculation Given (Equation 1) Where d = distance in cm P = Power in mW G = Numeric antenna gain S = Power Density in mW / cm2 Maximum Permissible Exposure EUT Output Power=54.33mW Numeric antenna gain=1.58 Substituting the MPE safe distance using d=20 cm into Equation 1 : Yields The power density S = 54.33× 1.58/ (4∏×400) cm2 =0.017mW/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.)
