It includes Bluetooth EDR and LE radio which complies with Bluetooth v2.1+EDR, v4.2, and v5.1. The Module is a highly integrated MAC/BBP and 2.4/5GHz PA/LNA single chip which supports a 866.7Mbps PHY rate. The Module is designed to support standard-based features in the areas of security, quality of service, and international regulations, giving end users the greatest performance anytime and in any circumstance. This documentation describes the engineering requirements specification. 1.1 RF module Overview The general HW architecture for the module is shown in Figure 1. This WLAN Module design is based on Mediatek MT7663BUN. It is a highly integrated single-chip MIMO(Multiple In Multiple Out) Wireless LAN (WLAN) network interface controller complying with the 802.11 specification and Bluetooth over USB interface. It combines a MAC, a 2T2R capable baseband, and RF in a single chip. An intelligent Wi-

Fi/Bluetooth coexistence algorithm is implemented to provide the best harmonized Wi-Fi and Bluetooth radio performance. 5V 1.5V Internal DC/DC 2.4G TX0/RX0 1.2V 5G TX0/RX0 Internal LDO WF_ RFIO Dixplexer Antenna0 USB2.0 Interface MT7663BU N 2.4G TX1/RX1 5G TX1/RX1 WF_ RFIO Dixplexer Antenna1 2.4G TX2/RX2 Filter 40MHz BT_ RFIO Filter Antenna2 Figure 1 WB7663B-LP1 Block Diagram 1.2 Specification reference Sichuan AI-

8Waste Disposal The disposal of the company's products should comply with local/superior regional/national/international applicable regulations. 9FCC Warning According to the definition of mobile and fixed device is described in Part 2.1091(b), this device is a mobile device. This Modular Approval is limited to OEM installation for mobile and fixed applications only. The antenna installation and operating configurations of this transmitter, including any applicable source-based time-

averaging duty factor, antenna gain and cable loss must satisfy MPE categorical Exclusion Requirements of 2.1091. It maintained at least a 20 cm separation between the EUT and the users body and must not transmit simultaneously with any other antenna or transmitter. For a host using this modular with a standard fixed label, if (1) the modules FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straight forward commonly used methods for access to remove the module so that the FCC identifier of the module is visible; then an additional permanent label referring to the enclosed module: Contains FCC ID: 2AOKI-

WFM63BUWP1 must be used. The host OEM user manual must also contain clear instructions on how end users can find and/or access the module and the FCC identifier. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the Federal Communications Commission (FCC) rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. Sichuan AI-

Dear Application Examiner;

2AOKI-WFM63BUWP1 is seeking full modular approval for module. The radio meets the requirements for modular approval as detailed in FCC 15.212. Compliance to each of the requirements is described below. 1. The radio elements must have the radio frequency circuitry shielded Yes, the modular transmitter has shield. 2. "The module must have buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal"

Yes, the modular transmitter has buffered modulation/data inputs ensure compliance with Part 15 under conditions of excessive data rates or over-modulation. All inputs are buffered through logic or microprocessor inputs. 3. "The module must contain power supply regulation on the module Yes, the modular transmitter has its own power supply regulation in the form of a low drop-out regulator providing V supply voltage to the board independently if the board is powered by the on-board battery or an external source. 4. The module must contain a permanently attached antenna, or contain a unique antenna connector, and be marketed and operated only with specific antenna(s), per 15.203, 15.204(b), 15.204(c), 15.212(a), 2.929(b) Yes, it contains unique antenna connectors and permanently attached. 5. The module must demonstrate compliance in a stand-alone configuration Yes, the module complies with Part 15 in a stand-alone configuration 6. The module must be labelled with its permanently affixed FCC ID label Yes, the modular transmitter is labelled with its own FCC ID number on itself (FCC ID:2AOKI-

WFM63BUWP1). Because the modular transmitter may be installed inside another device, rendering its own label invisible, the integration guide of the modular transmitter informs that the host device must visibly display the necessary text (Contains FCC ID: WFM63BUWP1) on the outside of the finished product. 7. The module must comply with all specific rules applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee Yes, the module is compliant with all applicable FCC rules. Instructions for maintaining compliance are given in the integration guide. 8. The module must comply with RF exposure requirements Yes, the module is compliant with all applicable RF exposure requirements. Please see RF Exposure Report. Sincerely, B ( ti ya. Hu Caixia Hu
