FCC RULES §1.1310 The criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in §1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of §2.1093 of this chapter.

Limits for occupational/controlled exposure also apply in situations when a person is transient through a location where occupational/controlled limits apply provided he or she is made aware of the potential for exposure. (2) General population/uncontrolled exposure limits apply in situations in which the general public may be exposed, or in which persons who are exposed as a consequence of their employment may not be fully aware of the potential for exposure or cannot exercise control over their exposure Page 6 of 11 UL VERIFICATION SERVICES INC.

EQUATIONS POWER DENSITY Power density is given by: S = EIRP / (4 * Pi * D^2) Where S = Power density in mW/cm^2 EIRP = Equivalent Isotropic Radiated Power in mW D = Separation distance in cm Power density in units of mW/cm^2 is converted to units of W/m^2 by multiplying by 10. DISTANCE Distance is given by: D = SQRT (EIRP / (4 * Pi * S)) Where D = Separation distance in cm EIRP = Equivalent Isotropic Radiated Power in mW S = Power density in mW/cm^2 SOURCE-BASED DUTY CYCLE Where applicable (for example, multi-slot cell phone applications) a duty cycle factor may be applied. Source-based time-averaged EIRP = (DC / 100) * EIRP Where DC = Duty Cycle in %, as applicable EIRP = Equivalent Isotropic Radiated Power in W Page 8 of 11 UL VERIFICATION SERVICES INC.

REPORT NO: 11536164-E2V4 DATE: MARCH 22, 2017 FCC ID: SBVRM013 IC: 5373-RM013 MIMO AND COLOCATED TRANSMITTERS (IDENTICAL LIMIT FOR ALL TRANSMITTERS) For multiple chain devices, and colocated transmitters operating simultaneously in frequency bands where the limit is identical, the total power density is calculated using the total EIRP obtained by summing the EIRP (in linear units) of each transmitter. Total EIRP = (EIRP1) + (EIRP2) + ... + (EIRPn) where EIRPx = Source-based time-averaged EIRP of chain x or transmitter x The total EIRP is then used to calculate the Power Density or the Distance as applicable. MIMO AND COLOCATED TRANSMITTERS For multiple colocated transmitters operating simultaneously in frequency bands where different limits apply: The Power Density at the specified separation distance is calculated for each transmitter chain or transmitter. The fraction of the exposure limit is calculated for each chain or transmitter as (Power Density of chain or transmitter) / (Limit applicable to that chain or transmitter). The fractions are summed. Compliance is established if the sum of the fractions is less than or equal to one. Page 9 of 11 UL VERIFICATION SERVICES INC.

LIMITS AND IC EXEMPTION VARIABLE LIMITS For mobile radio equipment operating in the cellular phone band, the lowest power density limit is calculated using the lowest frequency: 824 MHz / 1500 = 0.55 mW/cm^2 (FCC) S = 0.02619 ƒ 0.6834 W/m^2 (IC). FIXED LIMITS For operation in the PCS band, the 2.4 GHz band and the 5 GHz bands: From FCC §1.1310 Table 1 (B), the maximum value of S = 1.0 mW/cm^2 From IC Safety Code 6, Section 4 Table 4 Column 4, S = 0.02619 ƒ 0.6834 W/m^2 INDUSTRY CANADA EXEMPTION RF exposure evaluation is required if the separation distance between the user and/or bystander and the device’s radiating element is greater than 20 cm, except when the device operates as follows: • below 20 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1 W (adjusted for tune-up tolerance); • at or above 20 MHz and below 48 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 4.49/ƒ0.5 W (adjusted for tune-up tolerance), where ƒ is in MHz; • at or above 48 MHz and below 300 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 0.6 W (adjusted for tune-up tolerance); • at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1.31 x 10-2 ƒ0.6834 W (adjusted for tune-up tolerance), where ƒ is in MHz; • at or above 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 5 W (adjusted for tune-up tolerance).
