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 LLC FORM NO: 03-EM-F00858 12 Laboratory Dr., RTP, NC 27709 TEL: (919) 549-1400 This report shall not be reproduced except in full, without the written approval of UL LLC.

REPORT NO: R11005838-RF1 DATE: 2016-03-25 FCC ID: A94420128RM IC: 3232A-420128RM 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.

LIMITS AND IC EXEMPTION RF EXPOSURE LIMITS – GENERAL PUBLIC (UNCONTROLLED ENVIRONMENTS) FCC: 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 IC: For operation in the 300-6000 MHz band: Power Density = 0.02619f0.6834 Power Density (2.4 GHz) = 0.02619(2400)0.6834 = 4.4 W/m2 Power Density (5 GHz) = 0.02619(5150)0.6834 = 9.01 W/m2 Note – Lowest frequency that would yield the lowest limit was used. 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: Page 10 of 11 UL LLC FORM NO: 03-EM-F00858 12 Laboratory Dr., RTP, NC 27709 TEL: (919) 549-1400 This report shall not be reproduced except in full, without the written approval of UL LLC.

RF EXPOSURE RESULTS In the table(s) below, Power and Gain are entered in units of dBm and dBi respectively and conversions to linear forms are used for the calculations. (Single chain transmitters, no colocation, 20 cm MPE distance) Single Chain and non-colocated transmitters Band Mode Separation Output Antenna Duty EIRP FCC Power IC Power Distance AVG Gain Cycle Density Density Power (cm) (dBm) (dBi) (%) (mW) (mW/cm^2) (W/m^2) 2.4 GHz QPSK 20 5.08 2.20 100.0 5.3 0.001 0.01 5.2 GHz QPSK 20 10.83 5.02 100.0 38.5 0.008 0.08 5.8 GHz QPSK 20 11.31 5.56 100.0 48.6 0.010 0.10 Note - FCC Power Density Limit = 1mW/cm^2. IC Power Density Limit = 4W/m^2 (2.4 GHz) and 9W/m^2 (5 GHz). Notes: 1) For MPE the new KDB 447498 requires the calculations to use the maximum rated power; that power should be declared by the manufacturer, and should not be lower than the measured power. If the power has a tolerance then we also need to check that the measured power is within the tolerance. In this case, the manufacturer declared that the measured power is considered maximum. 2) A tolerance value of +2 dB was included in the output power values above to cover the output power tolerance of +/-2 dB under extreme conditions in the real filed as declared by the client. 3) The manufacturer configures output power so that the maximum power, after accounting for manufacturing tolerances, will never exceed the maximum power level measured. 4) The output power in the tables above is the maximum power per chain among various channels and various modes within the specific band. 5) The antenna gain in the tables above is the maximum antenna gain among various channels within the specified band.
