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 12 UL VERIFICATION SERVICES INC.

REPORT NO: 14U19707-E2A DATE: JULY 22, 2015 FCC ID: W7O24WN0 IC: 7693A-24WN0 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 12 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) 824 MHz / 150 = 5.5 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 2.2 Table 5 Column 4, S = 10 W/m^2 INDUSTRY CANADA EXEMPTION RSS-102 Clause 2.5.2 RF exposure evaluation is required if the separation distance between the user and the device’s radiating element is greater than 20 cm, except when the device operates as follows: •below 1.5 GHz and the maximum e.i.r.p. of the device is equal to or less than 2.5 W; •at or above 1.5 GHz and the maximum e.i.r.p. of the device is equal to or less than 5 W.
