Regulation RF Exposure FCC rule part 1.1307(b) KDB 447498 D04 Interim General RF Exposure Guidance v01 Part 1.1307(b)(3) - Determination of exemption. (i) For single RF sources (i.e., any single fixed RF source, mobile device, or portable device, as defined in paragraph (b)(2) of this section): A single RF source is exempt if: (A) The available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption may not be used in conjunction with other exemption criteria other than those in paragraph (b)(3)(ii)(A) of this section. Medical implant devices may only use this exemption and that in paragraph (b)(3)(ii)(A); KDB 447498 D04 2.1.2 - 1-mW Test Exemption Per § 1.1307(b)(3)(i)(A), a single RF source is exempt RF device (from the requirement to show data demonstrating compliance to RF exposure limits, as previously mentioned) if the available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption applies to all operating configurations and exposure conditions, for the frequency range 100 kHz to 100 GHz, regardless of fixed, mobile, or portable device exposure conditions. This is a standalone exemption, and it cannot be applied in conjunction with any other test exemption. * Equation 1 * Equation 2 S = power density (in appropriate units, e.g. mW/cm2) E = electric field strength (V/m) H = magnetic field strength (A/m) Z 0 = Impedance of free space (Ω) * Equation 3, By equations 1 and 2 EIRP at distance R = 3 m Evaluation Method OET Bulletin 65 Section 3: Methods of Predicting Human Exposure 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 OET Bulletin 65 Section 2: FCC Exposure Guidelines and Their Application S=퐸×퐻= 퐸 2 10푍 0 S= 푃퐺 4휋푅 2 S= 퐸퐼푅푃 4휋푅 2 퐸퐼푅푃푑퐵푚=퐸(푑퐵휇V/m) -104.77 + 20Log[R(m)] 퐸퐼푅푃푑퐵푚=퐸(푑퐵휇V/m) -95.23 Result FCC rule part 1.1307(b)(3) For determination of exemption. available maximum time-averaged power is no more than 1 mW, regardless of separation distance Frequency Maximum field strength @3m Calculated E.I.R.P.

The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this Section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. Result: Pass The transmitter has a Loop Antenna 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. 3.1.3 Configuration of Test System 3.2 Antenna requirement ICRT-QPA-17-03 Rev.2 Report No. ICRT-TR-E262041-0A 시 험 성 적 서 TEST REPORT 페이지(page) : (8) / 총(Total) (15) 4.

In the case of intentional radiators operating under the provisions of subpart E, the emission bandwidth may span across multiple contiguous frequency bands identified in that subpart. The requirement to contain the designated bandwidth of the emission within the specified frequency band includes the effects from frequency sweeping, frequency hopping and other modulation techniques that may be employed as well as the frequency stability of the transmitter over expected variations in temperature and supply voltage. If a frequency stability is not specified in the regulations, it is recommended that the fundamental emission be kept within at least the central 80% of the permitted band in order to minimize the possibility of out-of-band operation.
