Chongqing Shenzhen Taipei Non-SDR (Software Defined Radio) Cover Letter Date:2021/5/14 Refer to KDB 442812 D01 SDR apps Guide v02r03. The following six questions can be used for determining if a radio can elect to be, or must be an SDR. 1. Can the RF parameters of the device be altered through software? Yes - go to 2. No, not an SDR Yes 2. Can third parties not permitted by the Commission through specific filings modify, configure, or load different software, or make configuration settings to operate the device or host hardware radio frequency parameters (frequency range, modulation type, maximum output power or other radio parameters) in any other way than granted (or expected to be granted)? Yes, must be an SDR. No - go to 3. No 3. Is the device capable of operating in any other in any other way than granted, or will be, granted? Yes, - go to 4. No - go to 5. No 4. Is this a Part 15 client Device as defined in Section 15.202 (as opposed to a master device)? Yes, qualifies as a part 15 client devices - go to 5. No, must be an SDR. 5. Does the manufacturer elect SDR? Yes, elects to be an SDR. No, Not an SDR No Final conclusion: According to the above questions reply, we can confirm this (PROJECTOR), FCC ID: 2AZ3IMP250 must be a Non-SDR. The equipment can only support one exclusive regulation. The hardware devices will be locked to the activated regulatory domain and can’t be modified by any third party through configuration changes or software upgrades. The client only needs to download the software/firmware from official website, and this software/ firmware shall be authentication protocol by the manufacturer.

Chongqing Shenzhen Taipei SOFTWARE SECURITY REQUIREMENTS FOR U-NII DEVICES Date: May 14, 2021 ATTN: Pingan Dai FCC Subject: Attestation Letter regarding UNII devices FCC ID: 2AZ3IMP250, Software security questions and answers per KDB 594280 D02 v01r03: General Description 1 Describe how any software/firmware updates for elements than can affect the device’s RF parameters will be obtained, downloaded, validated and installed. For software that is accessed through manufacturer’s website or device’s management system, describe the different levels of security as appropriate. There is no downloadable software provided by the manufacturer that can modify critical radio transmitter parameters. All critical parameters are programmed in Chip memory at the factory and cannot be modified or overridden by third parties. 2 Describe the RF parameters that are modified by any software/firmware without any hardware changes. Are these parameters in some way limited such that any other software/firmware changes will not allow the device to exceed the authorized RF characteristics? There are no RF parameters that can be modified. All RF parameters are programmed in Chip memory at the factory and cannot be modified or overridden by third parties. 3 Describe in detail the authentication protocols that are in place to ensure that the source of the RF-related software/firmware is valid. Describe in detail how the RF-related software is protected against modification. The firmware in the factory has been fixed in to chip, can't change, so there is need for validation. Driver under it operating system provides a digital certificate authentication. 4 Describe in detail any encryption methods used to support the use of legitimate RF-related software/firmware. The firmware in the factory has been fixed in chip, can't be changed, there is no need for validation. Driver is in binary form, it is own closure, no need for verification. 5 For a device that can be configured as a master and client (with active or passive scanning), explain how the device ensures compliance for each mode? In particular if the device acts as master in some band of operation and client in another; how is compliance ensured in each band of operation? Not applicable, this device only supports client without radar detection. The RF parameters has been fixed in the wifi module firmware and cannot be altered, so the user has no way to break the compliance on the device. Third-Party Access Control 1 Explain if any third parties have the capability to operate a U.S.-sold device on any other regulatory domain, frequencies, or in any manner that may allow the device to operate in violation of the device’s authorization if activated in the U.S. Third parties do not have the capability to operate in any manner that is violation of the certification in the U.S Chongqing Shenzhen Taipei 2 Describe, if the device permits third-party software or firmware installation, what mechanisms are provided by the manufacturer to permit integration of such functions while ensuring that the RF parameters of the device cannot be operated outside its authorization for operation in the U.S. In the description include what controls and/or agreements are in place with providers of third-party functionality to ensure the devices’ underlying RF parameters are unchanged and how the manufacturer verifies the functionality. RF parameters are programmed into Chip memory at the factory and cannot be reprogrammed or re-flashed by third parties. 3 For Certified Transmitter modular devices, describe how the module grantee ensures that host manufacturers fully comply with these software security requirements for U-NII devices. If the module is controlled through driver software loaded in the host, describe how the drivers are controlled and managed such that the modular transmitter RF parameters are not modified outside the grant of authorization. There are no RF parameters that can be modified. All RF parameters are programmed in Chip memory at the factory and cannot be modified or overridden by third parties. The module is not controlled by driver software on the host and cannot override critical RF parameters stored in module Chip memory. USER CONFIGURATION GUIDE 1 Describe the user configurations permitted through the UI. If different levels of access are permitted for professional installers, system integrators or end-users, describe the differences. No UI provided. a) What parameters are viewable and configurable by different parties? None b) What parameters are accessible or modifiable by the professional installer or system integrators? None 1) Are the parameters in some way limited, so that the installers will not enter parameters that exceed those authorized? The module micro-code reads the parameters from the module Chip memory. These parameters cannot be modified or overridden by SW drivers. 2) What controls exist that the user cannot operate the device outside its authorization in the U.S.? Default mode is always FCC compliant. Other country modes cannot be activated without receiving three independent country codes from different APs, otherwise remains in FCC default mode (always FCC compliant) c) What parameters are accessible or modifiable by the end-user? None 1) Are the parameters in some way limited, so that the installers will not enter parameters that exceed those authorized? The module micro-code reads the parameters from the module Chip memory. These parameters cannot be modified or overridden by SW drivers. 2) What controls exist so that the user cannot operate the device outside its authorization in the U.S.? Default mode is always FCC compliant. Other country modes cannot be activated without receiving three independent country codes from different APs, otherwise remains in FCC default mode (always FCC compliant) d) Is the country code factory set? Can it be changed in the UI? Default country code is set in the factory and no UI is provided for modification…
