Avnet, Inc. 2211 South 47 th Street Phoenix, Arizona 85034 1/21/2022 Federal Communications Commission Office of Engineering and Technology 7435 Oakland Mills Road Columbia, MD 21046 To Whom It May Concern: This letter is to request Single Modular Approval in accordance with under FCC Rule Part 15.212(a)(1) for certification request under FCC ID: 2AF62-AVT3620U. This product provides a highly integrated Microsoft Azure Sphere end-to-end solution for high security, Wi-Fi connected embedded microcontroller-type applications. Declaration of conditions. Y/N 15.212(a)(1) Condition Y (i) The radio elements of the module have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements Y (ii) The module has buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over- modulation. Y (iii) The module has its own power supply regulation. Y (iv) The module complies with the antenna and transmission system requirements of §§15.203, 15.204(b) and 15.204(c). The antenna(s) are either permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). Y (v) The module was tested in a stand-alone configuration, i.e., the module was not inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it complies with the AC line conducted requirements found in §15.207. AC or DC power lines and data input/output lines connected to the module do not contain ferrites, unless they will be marketed with the module (see §15.27(a)). The length of these lines was the length typical of actual use or, if that length is unknown, at least 10 centimeters was used to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing were unmodified and commercially available (see §15.31(i)). Y (vi) The module is equipped with either a permanently affixed label or is capable of electronically displaying its FCC identification number. Y (vii) The module complies with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the applicant has provided adequate instructions along with the module to explain any such requirements. Y (viii) The module complies with any applicable RF exposure requirements in its final configuration. The instructions provided with the module adequately explain any usage conditions or restrictions. I acknowledge on behalf of the applicant that compliance of this module in all final configurations is the responsibility of the applicant under the condition that the integrator follows all provided installation instructions. Sincerely, Brandon Quintana Director, Advanced Solutions Engineering Avnet, Inc.

Wong CKC Laboratories, Inc. 5046 Sierra Pines Drive Mariposa, CA 95338 The test data contained in this report documents the observed testing parameters pertaining to and are relevant for only the sample equipment tested in the agreed upon operational mode(s) and configuration(s) as identified herein. Compliance assessment remains the client’s responsibility. This report may not be used to claim product endorsement by A2LA or any government agencies. This test report has been authorized for release under quality control from CKC Laboratories, Inc. Steve Behm Director of Quality Assurance & Engineering Services CKC Laboratories, Inc. Page 2 of 10 Report No: 105053-17A Revision History Original: Radio Frequency Exposure Report for Device: Secure Wi-Fi module Model: AES-MS-MT3620-UFL-M-G Rev2 Revision A: To update US and IC MPE Assessment Tables. Purpose: To demonstrate compliance with United States, Canada, Australia and/or European Union RF Exposure requirements for Portable equipment (devices used ≤20cm from the body) with power output below exemption levels or Mobile equipment (devices used >20cm from the body) where Maximum Permissible Exposure (MPE) Calculations apply. Device and Antenna Operating Configuration: Device operating at maximum output power with continuous transmission of modulated data. Test Procedure: This equipment is evaluated in accordance with the guidelines set forth in KDB 447498 & ANSI C95.1 for the US, Health Canada Safety Code 6 & RSS 102 for Canada, ARPANSA RPS3 for AU and EN 62479 or EN 62311 for EU. Other Considerations: Report considers stand-alone configurations only. RF Exposure limits are calculated at the mid-point of each operating band. The device does not transmit simultaneously in the 2.4and 5 GHz band Referenced Test Reports: The following test reports were referenced in conjunction with this assessment: 105053-12, 105053-23, 105053-24, 105053-25 12.4dBm, 12.2dBm, 12.6dBm (max) , 11.7dBm 105053-13 13.1dBm (max) 105053-29, 105053-26, 105053-27, 105053-2812.4dBm, 12.2dBm, 12.6dBm (max) , 11.7dBm 105053-15 13.1dBm (Max) Page 3 of 10 Report No: 105053-17A RF Exposure Power Density Assessment (Single Transmitter, Stand Alone) MPE Calculation: 푃표푤푒푟 퐷푒푛푠푖푡푦 ( 푆 ) = 퐸퐼푅푃 4휋 푑 2 Given: EIRP in mW or W and d in cm or m US MPE Assessment Power Reported is: ☒ Peak ☐ Average Limit Used is: ☒ General Population ☐ Occupational Exposure Operating Band MHz Power dBm Ant Type/Gain dBi EIRP dBm Distance cm MPE mW/cm 2 Limit mW/cm 2 Comments 2400-2483.5 13.1 Ext Patch / 1.9 15.0 20 0.0063 1.0 Pass 5150 - 5850 12.6 Ext Patch / 2.7 15.3 20 0.0067 1.0 Pass The device does not transmit simultaneously in the 2.4 and 5 GHz band IC MPE Assessment Power Reported is: ☒ Peak ☐ Average Limit Used is: ☒ General Population ☐ Occupational Exposure Operating Band MHz Power dBm Ant Type/Gain dBi EIRP dBm Distance m MPE W/m 2 Limit W/m 2 Comments 2400-2483.5 13.1 Ext Patch / 1.9 15.0 0.2 0.0629 5.41 Pass 5150 - 5850 12.6 Ext Patch / 2.7 15.3 0.2 0.0674 9.52 Pass The device does not transmit simultaneously in the 2.4 and 5 GHz band Page 4 of 10 Report No: 105053-17A Summary: Exemptions: Equipment demonstrating compliance by portable RF exposure exemption have been evaluated, without further testing, for use under either portable or mobile RF exposure configurations. Additional configurations including collocation or simultaneous transmission with other transmitters (including necessary separation distances) are subject to further assessment. Certain exemption criteria may define specific separation distances. It is assumed that the manufacturer shall design the equipment such that these minimum separation distance is met. MPE Calculation Results: Equipment demonstrating compliance with MPE calculations have been evaluated, without further testing, for use under mobile RF exposure configurations as identified herein. Additional configurations including collocation or simultaneous transmission with other transmitters (including necessary separation distances) are subject to further assessment. It is assumed that the manufacturer shall design the equipment such that the minimum separation distance of 20cm (or greater, as listed above) is met or that the manufacturer provides a protection guide (e.g. installation instructions) to the end user such that the antenna(s) may be installed in accordance with the manufacturer’s instructions in such a manor to maintain the minimum separation distance. General Comments: The absorption and distribution of Electromagnetic energy in the body is a very complex phenomena that depends on the mass, shape and physiological condition of the body; the orientation of the body with respect to the fields; and, the electrical properties of the body and the environment. Variables that may play a substantial role in possible biological effects are those that characterize the environment (including but not limited to: ambient temperature, air velocity, relative humidity and body insulation); and those that characterize the individual (including but not limited to: age, gender, activity level and existing debilitation or disease). Because innumerable factors may interact to determine specific biological effects of exposure to electromagnetic fields, any protection guide should consider both intended and unintended operational environments and provide guidance for installation and use of the product such that proper separation distances can be maintained. (ANSI C95.1).

RE: Dual Antenna Port Letter To whom it may concern: Regarding the dual antenna feature of the product, the manufacturer declares that simultaneous transmission on multiple antenna ports is not a permitted operational mode. Furthermore, transmission in multiple simultaneous bands of operation is not a permitted operational mode. Therefore, the RF exposure assessment including standalone, single port, single band configurations remains applicable for product compliance.
