FCC ID: RMN-CTS-RFID-LS21 SAR test exclusion considerations Guidance Applied: KDB 447498 D01v06 KDB 447498 D01 Section 4.3.1 Standalone SAR test exclusion considerations a) For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f (GHz) ] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR, where  f (GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  The result is rounded to one decimal place for comparison  The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm, and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 4.1 f) is applied to determine SAR test exclusion. b) For 100 MHz to 6 GHz and test separation distances > 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following (also illustrated in Appendix B): 1) {[Power allowed at numeric threshold for 50 mm in step a)] + [(test separation distance – 50 mm)·(f (MHz)/ 150)]} mW, for 100 MHz to 1500 MHz 2) {[Power allowed at numeric threshold for 50 mm in step a)] + [(test separation distance – 50 mm)·10]} mW, for > 1500 MHz and ≤ 6 GHz c) For frequencies below 100 MHz, the following may be considered for SAR test exclusion (also illustrated in Appendix C): 1) For test separation distances > 50 mm and < 200 mm, the power threshold at the corresponding test separation distance at 100 MHz in step b) is multiplied by [1 + log(100/f (MHz) )] 2) For test separation distances ≤ 50 mm, the power threshold determined by the equation in c) 1) for 50 mm and 100 MHz is multiplied by ½ 3) SAR measurement procedures are not established below 100 MHz. Determination of exemption according to KDB 447498 D01 Section 4.3.1 c) 2) Transmitting Frequency (MHz) Field strength (dBuV/m @3m) Max Power[EIRP] (dBm) Max power[EIRP] (mW) Separation distance (mm) Threshold at 50mm 4.3.1 a) In mW Threshold per 4.3.1 c)1) in mW Threshold per 4.3.1 c)2) in mW 0.134 104.75 9.59 9.09 5.0 474.3 1837.1 918.5 Note: EIRP was calculated using the following. EIRP = E Meas + 20log(d Meas ) - 104.7 EIRP: equivalent isotropically radiated power, in dBm E Meas : field strength of the emission at the measurement distance, in dBμV/m d Meas : measurement distance, in m Conclusion: SAR evaluation for general population exposure conditions by measurement or numerical simulation is not required.
