APPENDIX E [Yi Tunnel (Beijing) Technology Co., Ltd.] Attention: Certification reviewer RE: Request for Confidentiality FCC ID: 2A36J-VENUS20 To Whom It May Concern: Permanent Confidentiality [Complete this section if permanent confidentiality is requested] Request to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential: [Select one or more of items below, as appropriate] Schematics Block Diagrams Operational Description Tune-up Procedure Parts List Internal Photos (see note) Users Manual (see note) Note 1: Internal Photos may be held confidential 1) if the circuit board or internal components are not accessible to users. For example, it is acceptable if the circuit board is enclosed in epoxy. 2) Also, it is acceptable if the device is not accessible to the public, for example, a device mounted on the top of a large tower (or in a fenced enclosure) such that it is only serviceable by professional designated technicians under a Non-Disclosure Agreement (NDA). All sales for these devices must be under a NDA restricting the disclosure of the propriety information, including internal photos. Users Manual may be held confidential only when the manual contains proprietary technical information intended for professional technicians obligated under a NDA. All sales and distribution of the user’s manual must be under a NDA that restricts the disclosure of the information. In the application cover letter requesting permanent confidentiality the following additional description and the NDA exhibit is required: 1. Describe in detail how internal photos and/or users manual information are controlled to prevent them from becoming public or disclosed to unauthorized persons. 2. Describe how public access is restricted for products serviceable by professional designated technicians. 3. A statement that all sales of the non-consumer device will be under a NDA to include third party sales and that the final user of the device is subject to the NDA. 4. Provide an example of the NDA between the grantee and a purchaser. The request for confidentiality must Note 2: For scanning receiver, the schematics, block diagrams, operational description, tune-up procedure, parts list and internal photos are always held permanently confidential. Short-term Confidentiality [Complete this section if short-term confidentiality is requested] Request to withhold from public review for a period of [180] days from the date of the Grant of Equipment Authorization and prior to marketing, certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept short-term confidential for a period above from the date of the grant [Select one or more of items below that are not selected in the list above, as appropriate] Schematics Block diagrams Operational Description Tune-up Procedure Parts List Test Setup Photos External Photos Internal Photos Users Manual Rationale for request for confidentiality: We have invested considerable time and materials in research and development to produce the referenced product. Permanent confidentiality: Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. Short-term confidentiality: Disclosure of the short-term confidential portions of this application during the period of importation and/or distribution would reveal key aspects of proprietary technology to competitors and diminish the value of our investment in research and development. If you have questions or need further information, please contact the undersigned. Sincerely, _________________ [Guangjie Xiang] [Senior Manager] [Jan.6th, 2022]

Tune Up Procedure Tune-up procedure During manufacturing each Device is individually calibrated. Measurement is performed in a fully calibrated setup using an Agilent 8960 base station simulator (system tester). Measurement procedure is outlined below: Measurement Procedure: 1. Set the device to nominal operating voltage and on a predefined channel in a special test mode. 2. The actual output power is measured at several power levels. 3. The gain factors of each individual device are adjusted until the target value is met. The appropriate gain control settings for each output power level are stored in each device individually. The user has no possibility to change these settings. 4. The maximum gains of each individual device are adjusted and measured until the target value is met.

Test Report FCC ID: 2A36J-VENUS20 RF Exposure Venus 20-US-4G-PCIE-M2, Venus 20-CN-4G-NA-M2, and Venus 20-US-4G-NA-M2 are Engineering control equipments in the GSM/UMTS/LTE system. The GSM frequency band includes GSM850 and GSM900 and DCS1800 and PCS1900, but only GSM850/1900 test data included in this report. The UMTS frequency band are band I /II /IV/V/VI/VIII/XVIIII, but only band II and Band IV and Band V test data included in this report. The LTE frequency band is Band I/II/III/IV/V/VII/VIII/XII/XIII/XVIII/XVIIII/XX/XXV/XXVI/ XXVIII/XXXVIII/XXXVIIII/XXXX/XXXXI, but only Band II/IV/V/VII/XII/XIII/XXV/XXVI/XXXVIII/ XXXXI test data included in this report. The Engineering control equipments implements such functions as RF signal receiving/transmitting, LTE/UMTS and GPRS/EDGE protocol. Externally it provides micro SD card interface and USIM card interface. The EUT is powered by DC 12V/12.5A. For more detailed features description, please refer to the user’s manual.

The emissions should be within the limits at 300kHz in Table 1 of 1.1310(use the 300kHz limits for 150kHz:614V/m,1.63A/m). Friis Formula Friis transmission formula: Pd = (Pout*G)/(4* Pi * R 2) Where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Test Report FCC ID: 2A36J-VENUS20 Pd id the limit of MPE, 1 mW/cm 2 . If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached.
