REPORT NO:11752100B DATE: 2017-06-15 FCC ID: HBW1D8088-1 IC: 2666A-1D8088 5. MAXIMUM PERMISSIBLE RF EXPOSURE 5.1. 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. TABLE 1—LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency range Electric field strength Magnetic field strength Power density Averaging time (MHz) (V/m) (A/m) (mW/cm2) (minutes) (A) Limits for Occupational/Controlled Exposure 0.3-3.0 614 1.63 *100 6 2 3.0-30 1842/f 4.89/f *900/f 6 30-300 61.4 0.163 1.0 6 300-1,500 f/300 6 1,500-100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *100 30 1.34-30 824/f 2.19/f *180/f2 30 30-300 27.5 0.073 0.2 30 300-1,500 f/1500 30 1,500-100,000 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density Notes: (1) Occupational/controlled exposure limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. 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 10 UL LLC FORM NO: CCSUP4701J 333 Pfingsten Rd., Northbrook, IL 60062, USA TEL: (847) 272-8800 This report shall not be reproduced except in full, without the written approval of UL LLC

IC RULES IC Safety Code 6 (2015), Section 2.2.2: To ensure compliance with the basic restrictions outlined in Section 2.1, at frequencies between 10 MHz and 300 GHz, the reference levels for electric- and magnetic-field strength and power density must be complied with.

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 Page 8 of 10 UL LLC FORM NO: CCSUP4701J 333 Pfingsten Rd., Northbrook, IL 60062, USA TEL: (847) 272-8800 This report shall not be reproduced except in full, without the written approval of UL LLC

REPORT NO:11752100B DATE: 2017-06-15 FCC ID: HBW1D8088-1 IC: 2666A-1D8088 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. 5.4. IC EXEMPTION 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:  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; Page 9 of 10 UL LLC FORM NO: CCSUP4701J 333 Pfingsten Rd., Northbrook, IL 60062, USA TEL: (847) 272-8800 This report shall not be reproduced except in full, without the written approval of UL LLC

REPORT NO:11752100B DATE: 2017-06-15 FCC ID: HBW1D8088-1 IC: 2666A-1D8088 6. 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. 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.

For the 2.4GHz WiFi radio the maximum power measured based on the report for the module is set to 23.7dBm.
