RF Exposure evaluation Exposure category: General population/uncontrolled environment EUT Type: Production Unit Device Type: Mobile Device Refer Standard: KDB 447498 D01 General RF Exposure Guidance v06 FCC Part 2 §2.1091 FCC ID: 2AWHGTK-83 1. Reference According to §1.1307(b)(1), 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 level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. KDB447498 D01: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 2. Limit Limits for Maximum Permissible Exposure (MPE)/Controlled Exposure Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density (mW/cm²) Averaging Time (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 614 1.63 (100) * 6 3.0 – 30 1842/f 4.89/f (900/f 2 )* 6 30 – 300 61.4 0.163 1.0 6 300 – 1500 / / f/300 6 1500 – 100,000 / / 5 6 Limits for Maximum Permissible Exposure (MPE)/Uncontrolled Exposure Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density (mW/cm²) Averaging Time (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 614 1.63 (100) * 30 3.0 – 30 824/f 2.19/f (180/f 2 )* 30 30 – 300 27.5 0.073 0.2 30 300 – 1500 / / f/1500 30 1500 – 100,000 / / 1.0 30 F=frequency in MHz *=Plane-wave equivalent power density 3. MPE Calculation Method Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna 4. Result As declared by the Applicant, the EUT is a wireless device used in a fix application, at least 20 cm from any body part of the user or nearby persons; from the maximum EUT RF output power, the minimum separation distance, r =20cm, as well as the gain of the used BT antenna is 2 Bi, the RF power density can be obtained. EDR Freq. (MHz) Output Power (dBm) Target power W/ tolerance (dBm) Max tune up power tolerance (dBm) Output power to antenna (mW) Ant Gain (dBi) Power Density at R=20cm (mW/cm2) Limit (mW/c m2) Result GFSK 2402 -2.145 -2±1.0 -1 0.794 -6 0.00004 1 Pass 2440 -2.635 -2±1.0 -1 0.794 -6 0.00004 1 Pass 2480 -2.974 -2±1.0 -1 0.794 -6 0.00004 1 Pass π/4DQPSK 2402 -2.623 -2±1.0 -1 0.794 -6 0.00004 1 Pass 2440 -2.941 -2±1.0 -1 0.794 -6 0.00004 1 Pass 2480 -3.032 -3±1.0 -2 0.631 -6 0.00003 1 Pass Note: The estimation distance is 20cm 5. Conclusion The measurement results comply with the FCC Limit per 47 CFR 2.1091 for the uncontrolled RF Exposure of mobile device.
