The physical crystal and tuning capacitors may be located external to the shielded radio elements The Module has its own shielding. Please refer External Photographs Yes 02 The modular transmitter must have 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 All modulation and data input(s) are buffered.” The EUT has buffered data inputs, it is integrated on chip RS9110 Yes 03 The modular transmitter must have its Own power supply regulation. PMU is built into RS9110 chip. Yes 04 The modular transmitter must comply with the antenna and transmission system requirements of Sections 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and The antenna, including the cable). The “professional installation” provision of Section 15.203 is not applicable to modules but can apply to limited Modular approvals under paragraph (b) of this section. The EUT meets the FCC antenna requirements. The spurious emission, unique antenna connector and photo of antennas are shown in the test report. Yes 05 The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance With Part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the Module (see Section 15.27(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters 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 The modular transmitter was tested in a stand-alone configuration via a SDIO interface. Yes module during testing shall be Unmodified and commercially available (see Section 15.31(i)). 06 The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC Identification number. (A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is Installed must also display a label referring to The enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording That expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate Instructions along with the module which explain This requirement. In the latter case, a copy of these instructions must be included in the Application for equipment authorization. (B) If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the Device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed Module. This exterior label can use wording such as the following: “Contains FCC certified transmitter module(s).” Any similar wording that expresses the same Meaning may be used. The user manual must include instructions on how to access the Electronic display. A copy of these instructions Must be included in the application for equipment authorization. In the exhibition OEM manual, there are instructions given to the OEM on how to label the end product. Yes 07 The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a . The EUT is compliant with all applicable FCC rules. Detail Yes complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such Requirements. A copy of these Instructions must be included in the application for equipment authorization. instructions for maintaining compliance are given in the OEM Manual. 08 The modular transmitter must comply with any applicable RF exposure requirements in its final configuration Please see maximum permissible exposure information report Yes A full modular approval may be granted for single or split modular transmitters that do not comply with all of the above requirements, e.g., shielding, minimum signaling amplitude, buffered modulation/data inputs, or power supply regulation, if the manufacturer can demonstrate by alternative means in the application for equipment authorization that the modular transmitter meets all the applicable Part 15 requirements under the operating conditions in which the transmitter will be used. Limited modular approval also may be granted in those instances where compliance with RF exposure rules is demonstrated only for particular product configurations. The applicant for certification must state how control of the end product into which the module will be installed will be maintained such that full compliance of the end product is always ensured Sincerely, A.

www.tuv.com Appendix 10 Prüfbericht - Nr.: Test Report No. 19660011 001 Seite 1 von 2 Page 1 of 2 RF Exposure Report RF Exposure Measurement The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over- prediction for near field power density. It is taken as worst case to specify the safety range. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of the human exposure to radio-frequency (RF) radiation as specified in 1.1307 (b) Limits for Maximum Permissible Exposure (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm²) Limits for Occupational / controlled Exposures 300 - 1500 -- -- F/300 1500 – 100000 -- -- 5.0 Limits for General population / Uncontrolled Exposure 300 - 1500 -- -- F/1500 1500 – 100000 -- -- 1.0 F= Frequency in MHz www.tuv.com Appendix 10 Prüfbericht - Nr.: Test Report No. 19660011 001 Seite 2 von 2 Page 2 of 2 Friss Formula Friss Transmission Formula: Pd = (Pout * G) / (4*pi*r²) Where Pd = power density in mW/cm² Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = Distance between observation point and the center of radiator in cm If we know the maximum gain of the antenna and the total output power to the antenna, through calculation, we will know MPE value at distance 20cm. EUT Operation condition EUT was enabled to transmit and receive at lowest, middle and highest channels. Classification The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance from the antenna should be included in the User manual. So, this device is classified as Mobile device.
