LIMITS for FCC SAR Evaluation KDB 447498 D04 Interim General RF Exposure Guidance v01, section 2.1.3 SAR-Based Exemption: “A more comprehensive exemption, considering a variable power threshold that depends on both the separation distance and power, is provided in § 1.1307(b)(3)(i)(B). This exemption is applicable to the frequency range between 300 MHz and 6 GHz, with test separation distances between 0.5 cm and 40 cm, and for all RF sources in fixed, mobile, and portable device exposure conditions.” 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 FCC KDB 447498 D01 General RF Exposure Guidance v06, section 4.3.1 & Appendix A provides the SAR Test Exclusion Thresholds (ERP/Conducted) to verify that the device is exempt from 1-g extremity SAR at different separation distances. As example, for 900MHz Tx: 16mW (12dBm); For 2450MHz Tx: 10mW (10dBm) at ≤5 mm.

Example: Exclusion Thresholds to verify that the 2450MHz Tx is exempt from 1-g SAR at separation distance of ≤5 mm: 3mW (4.77dBm) & 10-g SAR at separation distance of ≤5 mm: 7.5mW (8.75dBm).

Summary For FCC and IC, that max. declared power level can be modified by any duty cycle over the time averaging period. Time-averaging period is a time period not to exceed 30 minutes for fixed RF sources or a time period inherent from device transmission characteristics not to exceed 30 minutes for mobile and portable RF sources. For rf exposure, the averaging period is 6 minutes for ISED Canada and for FCC it varies by frequency but 1~60 second for RF exposure or the period specified by product design spec. for RF exposure can be used. So the power value for RF exposure= Declared power x Duty Cycle factor EUT: Ysia 1 HP Zigbee II, Ysia 5 HP Zigbee II, Ysia 5 TDBU HP Zigbee II Report No: 0048-260706-01 Model: 5175210B, 5175211B, 5175066B FCC ID: DWNV2TDBUBL IC : 12049A-V2TDBUBL Page 32 of 76 Advanced Compliance Laboratory, Inc. 210 Cougar Court, Hillsborough, NJ 08844, tel:(908) 927 9288 CALCULATIONS for MPE distance and Power Density Given E = √ (30 * P * G) / d and S = E ^ 2 / 3770 where E = Field Strength in Volts/meter P = Power in Watts G = Numeric antenna gain d = Distance in meters S = Power Density in milliwatts/square centimeter Combining equations and rearranging the terms to express the distance as a function of the remaining variables yields: d = √ ((30 * P * G) / (3770 * S)) Changing to units of Power to mW and Distance to cm, using: P(mW) = P (W) / 1000 and d (cm) =100 * d (m) yields d = 100 * √ ((30 * (P / 1000) * G) / (3770 * S)) d = 0.282 * √ (P * G / S) where d = distance in cm P = Power in mW G = Numeric antenna gain S = Power Density in mW/cm^2 Substituting the logarithmic form of power and gain using: P (mW) = 10 ^ (P (dBm) / 10) and G (numeric) = 10 ^ (G (dBi) / 10) yi elds d = 0.282 * 10 ^ ((P + G) / 20) / √ S Equation (1) S = 0.0795 * 10 ^ ((P + G)/10)/ d^2 Equation (2) where d = MPE distance in cm P = Power in dBm G = Antenna Gain in dBi S = Power Density Limit in mW/cm^2 Equation (1) and the measured Output power is used to calculate the MPE distance.
