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 13 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 13 UL VERIFICATION SERVICES INC.

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 13 UL VERIFICATION SERVICES INC.

REPORT NO: 16U23555-E29V4 DATE: August 17, 2016 FCC ID: A4RNC2-6A5-D IC: 10395A-NC26A5D 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. 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.
