1. General Functions The wireless module complies with IEEE 802.11 b/g/n standard and it can achieve up to a speed of 65Mbps with single stream in 802.11n, 54Mbps as specified in IEEE 802.11g, or 11Mbps for IEEE 802.11b to connect to the wireless LAN. This compact module is a total solution for a combination of Wi-Fi 802.11b/g/n technologies with Microcontroller Processor. The module is specifically developed for embedded system devices. 2.

a high quality of power supply for the whole module. Flash is used for the external expansion memory. The Excellent matching circuit in RF-Front ensures that the signal has minimal signal loss and radiation. The MCU provides the interfaces for a variety of peripherals (Timer, PWM, Interrupt, AD, the Debug) from the module to the baseboard. Each peripheral that connects to the MCU I/O pins can choose between two different I/O pin locations with the provided flexibility in various applications. 4.

Requirement of FCC KDB 996369 D03 for module certification: 5.1 List of applicable FCC rules and Canada rules: The module complies with FCC Part 15.247, and Canada RSS-247. 5.2 Summarize the specific operational use conditions: The module has been certified for Fix/Mobile applications.
operated to provide a separation distance of at least 20 cm from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter. Installers must ensure that 20cm separation distance will be maintained between the device and users. DÉCLARATION D’IC SUR L’EXPOSITION AUX RADIATIONS: Cet appareil est conforme aux limites d’exposition au rayonnement RF stipulées par la FCC et l’IC pour une utilisation dans un environnement non contrôlé.
could void the user’s authority to operate the equipment. Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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 FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
aux CNRd’ Innovation, Sciences et Développement économique Canada applicables aux appareils radio exempts de licence. L’ exploitation est autorisée aux deux conditions suivantes : 1) L’ appareil ne doit pas produire de brouillage; 2) L’ appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptibled’en compromettre le fonctionnement. The system integrator must place an exterior label on the outside of the final product housing the GRJW06-J Modules.
5.9 Additional testing, Part 15 Subpart B disclaimer: The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) list on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains digital circuity.
