1.Regulation RF Exposure FCC rule part 1.1310(d) (1) Evaluation with respect to the SAR limits in this section must demonstrate compliance with both the whole-body and peak spatial-average limits using technically supported measurement or computational methods and exposure conditions in advance of authorization (licensing or equipment certification) and in a manner that facilitates independent assessment and, if appropriate, enforcement. Numerical computation of SAR must be supported by adequate documentation showing that the numerical method as implemented in the computational software has been fully validated; in addition, the equipment under test and exposure conditions must be modeled according to protocols established by FCC-accepted numerical computation standards or available FCC procedures for the specific computational method. (2) For operations within the frequency range of 300 kHz and 6 GHz (inclusive), the limits for maximum permissible exposure (MPE), derived from whole-body SAR limits and listed in Table 1 in paragraph (e)(1) of this section, may be used instead of whole-body SAR limits as set forth in paragraphs (a) through (c) of this section to evaluate the environmental impact of human exposure to RF radiation as specified in § 1.1307(b) of this part, except for portable devices as defined in § 2.1093 of this chapter as these evaluations shall be performed according to the SAR provisions in § 2.1093. 2.Evaluation Method OET Bulletin 65 Section 2: PREDICTION METHODS_Equations for Predicting RF Fields S = power density (in appropriate units, e.g. mW/cm2) P = power input to the antenna (in appropriate units, e.g., mW) 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 (appropriate units, e.g., cm) EIRP = equivalent (or effective) isotropically radiated power 1 / 3 3.Limit Table 1 to § 1.1310(e)(1)—Limits for Maximum Permissible Exposure (MPE) 2 / 3 ± 1.0 Power density at 20 ㎝ [mW/cm 2 ] 0.000 14 Notes. 1. Power density(S) = 10^((Max Tune-up Power + Ant Gain )/10) / (4 x π x R 2 ) 2. Since the EUT employs an integral antenna and the EIRP was derived from the measured radiated field strength of the complete device, no additional antenna gain was applied. 3.

Test Summary 3.3 Test Methodology - Both conducted and radiated testing was performed according to the procedures in ANSI C63.10-2020. Radiated testing was performed at a distance of 3 m from EUT to the antenna. 3.4 Configuration of Test System - To determine whether the equipment under test fulfills the requirements of the standards stated in FCC Part 15 Subpart C Section 15.209 & RSS-Gen 3.2 Purpose of the test - Both conducted and radiated testing was performed according to the procedures in ANSI C63.10-2020. Radiated testing was performed at a distance of 3 m from EUT to the antenna. 3.4.1 Radiated emission test - Preliminary radiated emissions test were conducted using the procedure in ANSI C63.10-2020 to determine the worse operating conditions. Final radiated emission tests were conducted at 3 m Semi Anechoic Chamber. The turntable was rotated through 360 degrees and the EUT was tested by positioned three orthogonal planes to obtain the highest reading on the field strength meter. Once maximum reading was determined, the search antenna was raised and lowered in both vertical and horizontal polarization.
