Hui Zhou Gaoshengda Technology Co., LTD U-NII devices declaration letter We, Hui Zhou Gaoshengda Technology Co.,LTD declare that: FCC ID: 2AC23-WCT6LA2701 IC: 12290A-WCT6LA2701 SOFTWARE SECURITY DESCRIPTION General 1. Describe how any software/firmware There is no downloadable software Description updates for elements than can affect the provided by the manufacturer that can device’s RF parameters will be obtained, modify critical radio transmitter downloaded, validated and installed. For parameters. All critical parameters are software that is accessed through programmed in OTP memory at the manufacturer’s website or device’s factory and cannot be modified by third management system, describe the different parties. levels of security as appropriate. 2. Describe the RF parameters that are There are no RF parameters that can by modified by any software/firmware without modified. ALL RF parameters are any hardware changes. Are these programmed in OTP memory at the parameters in some way limited such that factory and cannot be modified by third any other software/firmware changes will parties. not allow the device to exceed the authorized RF characteristics? 3. Describe in detail the authentication The NVRAM of the module can only be protocols that are in place to ensure that written once and cannot be written after the source of the RF-related delivery. software/firmware is valid. Describe in detail how the RF-related software is protected against modification. 4. Describe in detail any encryption methods The NVRAM of the module can only be used to support the use of legitimate written once and cannot be written after RF-related software/firmware. delivery. 5. For a device that can be configured as a This is client module only. 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?

Hui Zhou Gaoshengda Technology Co., LTD Third-Party 1. Explain if any third parties have the Third parties do not approved to operate Access Control capability to operate a U.S.-sold device on in any manner that is violation of the any other regulatory domain, frequencies, certification in the U.S. or in any manner that may allow the device to operate in violation of the device’s authorization if activated in the U.S. 2. Describe, if the device permits third-party The firmware is programmed at the software or firmware installation, what factory and cannot be modified by third mechanisms are provided by the parties. 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. 3. For Certified Transmitter modular devices, There are no RF parameters that can by describe how the module grantee ensures modified. ALL RF parameters are that host manufacturers fully comply with programmed in OTP memory at the these software security requirements for factory and cannot be modified by third U-NII devices. If the module is controlled parties. The module is not controlled by through driver software loaded in the host, driver software on the host and cannot describe how the drivers are controlled and modify any critical RF parameters managed such that the modular transmitter stored in module OTP memory. RF parameters are not modified outside the grant of authorization. Page 2 of 4 Reference (active link): 594280 D02 U-NII Device Security v01r03

Hui Zhou Gaoshengda Technology Co., LTD SOFTWARE SECURITY DESCRIPTION USER 1. Describe the user configurations permitted No UI provided. CONFIGURATION through the UI. If different levels of access GUIDE are permitted for professional installers, system integrators or end-users, describe the differences. a. What parameters are viewable and None configurable by different parties? b. What parameters are accessible or None modifiable by the professional installer or system integrators? 1) Are the parameters in some way The module micro-code reads the limited, so that the installers will parameters from the Module OTP not enter parameters that exceed memory. These parameters cannot be those authorized? modified by SW driver. 2) What controls exist that the user Default mode is always FCC compliant. cannot operate the device outside Other country modes cannot be its authorization in the U.S.? activated without writing in the drive's bin files. However, bin files can only be modified at the factory c. What parameters are accessible or None modifiable by the end-user? 1) Are the parameters in some way The module micro-code reads the limited, so that the user or parameters from the Module OTP installers will not enter memory. These parameters cannot be parameters that exceed those modified by SW driver. authorized? 2) What controls exist so that the Default mode is always FCC compliant. user cannot operate the device Other country modes cannot be outside its authorization in the activated without writing in the drive's U.S.? bin files. However, bin files can only be modified at the factory d. Is the country code factory set? Can it Default country code is set in the factory be changed in the UI? and no UI is provided for modification. 1) If it can be changed, what controls Default mode is always FCC compliant. exist to ensure that the device can Other country modes cannot be only operate within its activated without writing in the drive's authorization in the U.S.? bin files. However, bin files can only be modified at the factory e. What are the default parameters when Always FCC compliant. the device is restarted? 2. Can the radio be configured in bridge or No Page 3 of 4 Reference (active link): 594280 D02 U-NII Device Security v01r03

Hui Zhou Gaoshengda Technology Co., LTD mesh mode? If yes, an attestation may be required. Further information is available in KDB Publication 905462 D02. 3. For a device that can be configured as a This is a client device. master and client (with active or passive scanning), if this is user configurable, describe what controls exist, within the UI, to ensure compliance for each mode. If the device acts as a master in some bands and client in others, how is this configured to ensure compliance? 4. For a device that can be configured as This device is not an access point. different types of access points, such as point-to-point or point-to-multipoint, and use different types of antennas, describe what controls exist to ensure compliance with applicable limits and the proper antenna is used for each mode of operation.
