All transmitters, regardless if it is categorically excluded, are assessed to ensure the product can operate in manners that meet or exceed the minimum test separation distance as required by KDB 447498. 2.2 Maximum Permissible Exposure Limit The Maximum Permissible Exposure (MPE) limits for general population/uncontrolled exposure is as follows: Frequency E-field H-field Power density Averaging time Range strength strength (mW/cm2) (minutes) (MHz) (V/m) (A/m) 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 * = Plane-wave equivalent power density 2.3 Assessment Methods The power density is calculated according to the following equation 𝐸𝐼𝑅𝑃 𝑆= 4𝜋𝑅2 Where S = Power Density (mW/cm2) EIRP = Effective Isotropic Radiated Power (mW) R = Minimum distance between the human body and antenna (cm) Report Number: 31951957.001 Page 5 of 6 EUT: MyQ B-Hub Model: MyQ B-Hub Report Date: April 22, 2019

Pleasanton, CA 94566 Tel: (925) 249-9123, Fax: (925) 249-9124 2.4 Assessment Calculation The maximum output power and antenna gain is declared by the manufacturer and used in this assessment. The minimum RF exposure distance during normal operation is 20 cm. Stand Alone Analysis Power Frequency Power Density Band Operating EIRP Density Limit Percentage (MHz) Mode (mW) (mW/cm2) (mW/cm2) of Limit 310 – 390 300 MHz 0.047 0.000009 0.260 0.0% Transceiver 902 – 928 900 MHz 10 0.0020 0.619 0.3% Transceiver 2400 – 2483.5 802.11b/g/n 63.10 0.013 1.0 1.3% 2400 – 2483.5 Bluetooth LE 11.22 0.0022 1.0 0.2% Simultaneous Transmission Analysis For each simultaneous transmission configuration, the sum of the percentages to the limit of each radio should not exceed 100%. Simultaneous Transmission Configuration Percentage of Limit Sum of Percentages 300 MHz Transceiver 0.0% 802.11b/g/n 1.3% 1.5% Bluetooth LE 0.2% 900 MHz Transceiver 0.3% 802.11b/g/n 1.3% 1.8% Bluetooth LE 0.2% 2.5 Conclusion The EUT was found to be compliant to the requirements of FCC part 1.1310 and part 2.1091 with a minimum distance of 20 cm.
