FCC Statement

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and
2. this device must accept any interference received, including interference that may cause undesired operation. Any Changes or modifications 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. 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.

The Module is designed to comply with the FCC statement. FCC ID is 2AL6KBL- M8811CU5. The host system using Module, should have label indicated it contain modular’s FCC ID: 2AL6KBL-M8811CU5. This radio module must not installed to colocate and operate simultaneously with other radios in host system additional testing and equipment authorization may be required to operating simultaneously with other radio.

The Module and its antenna must not be co-located or operating in conjunction with any other transmitter or antenna within a host device.

The modular must be installed in the host that assigns by the Company name: Shenzhen Bilian Electronic Co.,Ltd. Model no. : BL-M8811CU5, if other host types used would need further evaluation and possible C2PC if they are not significantly similar to the one, tested The WIFI Module is deaigned for a compact PCB design .It should be installed and operated with host or other minimum distance of 20 centimeters between the radiator and your body.” To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed 2dBi in the 2.4G band and 2.75dBi in the 5G band. The module uses an IPEX antenna interface and use dipole antenna,this antenna is sold with the module.

Notice to OEM integrator The end user manual shall include all required regulatory information/warnings as show in this manual. The OEM integrator is responsible for testing their end product for any additional compliance requirements required with this module installed. If the final product contains circuits of other FCC PART 15 Subparts, the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

The intended use is generally not for the general public. lt is generally for industry/commercial use. The connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter that is not normally required, the user has no access to the connector. Installation must be controlled. Installation requires special training. This device complies with Part 15 of the FCC Rules. This equipment should be installed and operated with a minimum distance of 20 cm between the radiator and your body

Operations in the 5.15-5.35GHz band are restricted to indoor usage only.
