"IMPORTANT NOTICE FOR ALL USERS OR DISTRIBUTORS: Intel wireless LAN adapters are engineered, manufactured, tested, and quality checked to ensure that they meet all necessary local and governmental regulatory agency requirements for the regions that they are designated and/or marked to ship into. Because wireless LANs are generally unlicensed devices that share spectrum with radars, satellites, and other licensed and unlicensed devices, it is sometimes necessary to dynamically detect, avoid, and limit usage to avoid interference with these devices. In many instances Intel is required to provide test data to prove regional and local compliance to regional and governmental regulations before certification or approval to use the product is granted. Intel's wireless LAN's EEPROM, firmware, and software driver are designed to carefully control parameters that affect radio operation and to ensure electromagnetic compliance (EMC). These parameters include, without limitation, RF power, spectrum usage, channel scanning, and human exposure. For these reasons Intel cannot permit any manipulation by third parties of the software provided in binary format with the wireless LAN adapters (e.g., the EEPROM and firmware). Furthermore, if you use any patches, utilities, or code with the Intel wireless LAN adapters that have been manipulated by an unauthorized party (i.e., patches, utilities, or code (including open source code modifications) which have not been validated by Intel), (i) you will be solely responsible for ensuring the regulatory compliance of the products, (ii) Intel will bear no liability, under any theory of liability for any issues associated with the modified products, including without limitation, claims under the warranty and/or issues arising from regulatory non-compliance, and (iii) Intel will not provide or be required to assist in providing support to any third parties for such modified products. Note: Many regulatory agencies consider Wireless LAN adapters to be "modules", and accordingly, condition system-level regulatory approval upon receipt and review of test data documenting that the antennas and system configuration do not cause the EMC and radio operation to be non-compliant."

Intel Corporation 100 Center Point Circle Columbia, SC 29210 January 6, 2013 Federal Communications Commission 7435 Oakland Mills Road Columbia, Maryland 21046 USA Subject: Model 6235ANNGW Wireless LAN mini-PCIe Card FCC ID’s: PD96235ANNG and PD96235ANNGU Gentlemen: Please be advised that the Model 6235ANNGW 802.11abgn + BT Wireless LAN mini-PCIe card is manufactured for the global market but when marketed in the U.S. under FCC ID’s PD96235ANNG and PD96235ANNGU the non-volatile memory (NVM) will be programmed at the factory to only actively scan and operate on these specific channels during normal WLAN operation. During Wi-Fi Direct mode the device may act as a group owner (GO) to establish a peer-to-peer (P2P) network including conditions when no master device is present on these specific channels. Channels 1-11, 2412-2462MHz 802.11b mode Channels 1-11, 2412-2462MHz 802.11g mode Channels 1-11, 2412-2462MHz 802.11n mode (20MHz channel) Channels 3-9, 2422-2452MHz 802.11n mode (40MHz channel) The device will be programmed at the factory to passively scan on the following dynamic frequency selection (DFS) channels and will only listen for a master device and cannot send a probe request to initiate communication on these DFS channels. Client software and drivers will never enable the device to act as a master or GO for operation in DFS frequency bands and therefore ad-hoc mode is always disabled on these passive scan DFS channels. Channels 52-64, 5260-5320MHz 802.11a mode Channels 52-64, 5260-5320MHz 802.11n mode (20 MHz channel) Channels 54-62, 5270-5310MHz 802.11n mode (40MHz channel) Channels 100-140, 5500-5700MHz 802.11a mode Channels 100-140, 5500-5700MHz 802.11n mode (20 MHz channel) Channels 102-134, 5510-5670MHz 802.11n mode (40MHz channel) This device meets the requirements of FCC Part 15.202 and accordingly will be programmed at the factory to passively scan on the following non-DFS channels and will only listen for a master device and cannot send a probe request to initiate communication during normal WLAN operation. When operating in Wi-Fi Direct mode on these non-DFS channels, it may operate as a P2P client device or GO to establish a P2P network if, and only if, a master Intel Corporation 100 Center Point Circle Columbia, SC 29210 device is present and network communication is maintained between a master device and the GO. Channels 12 &13, 2467 & 2472MHz 802.11b mode Channels 12 &13, 2467 & 2472MHz 802.11g mode Channels 12 &13, 2467 & 2472MHz 802.11n mode (20MHz channel) Channels 10 &11, 2457 & 2462MHz 802.11n mode (40MHz channel) Channels 36-48, 5180-5240MHz 802.11a mode Channels 36-48, 5180-5240MHz 802.11n mode (20 MHz channel) Channels 38-46, 5190-5230MHz 802.11n mode (40MHz channel) Channels 149-165, 5745-5825 802.11a mode Channels 149-165, 5745-5825MHz 802.11n mode (20 MHz channel) Channels151-159, 5755-5795 802.11n mode (40MHz channel) This information when programmed into the NVM will not be accessible and cannot be changed by the end user. The transmitter is approved as a non-software defined radio and OEMs and third party system integrators do not have the ability through software to allow configuration controls that would permit the device to operate outside the grant conditions per FCC KDB 594280.

Intel Corporation 100 Center Point Circle Columbia, SC 29210 Modular Approval Requirements Attestation FCC ID: PD96235ANNGU Limited Modular Approval is being requested for this device under the ID listed above. Modules authorized under this ID are intended for installation into the host systems by the end users. In order to ensure compliance with all modular requirements, including RF exposure, the host system will be provided with a BiOS-lock feature that will allow operation of authorized modules only. The BiOS-lock feature will lock-out any unauthorized devices from operation with the host system. This device is a self contained, physically delineated, component for which compliance was demonstrated independent of any host operating conditions and complies with all requirements of FCC Part 15.212(a)(1). The details of these requirements and the manner in which the devices meet them are summarized below. The module must have its own RF shielding. The module contains a metal shield which covers all RF components and circuitry; this shield is located on the top side of the board located next to the antenna connectors. All modulation and data input(s) are buffered. Data to the modulation circuit is buffered on the module; please refer to the “theory of operation” document filed with this application for full description. The module has its own power supply regulation and local reference oscillator. The module contains its own power supply regulation and the rf reference oscillator is contained within the module. Please refer to the schematics and “theory of operation” documents filed with this application for full description. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). The certification submission contains a detailed description of all antennas that will be used with the module. The module connects to its antenna via using an UFL type connector. This antenna connector is a non-standard connector. The antenna tested was a PIFA type and the data sheet is included in the application. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. Intel Corporation 100 Center Point Circle Columbia, SC 29210 Test data contained in this application is for the device tested as a stand-alone device connected externally to a PC. See test set-up photographs filed with this application. For the FCC, the modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID 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.” The module is appropriately labeled (refer to the label and label location drawings contained within this application). Information to the integrator of this device regarding the labeling requirements for the host system is contained in the instructions provided with the module. The modular transmitter must comply with any applicable RF exposure requirements. The module meets the requirements for a portable device that may be used at separation distances of more than 8mm from the human body. Refer to the RF Exposure test report submitted with this application.
