FCC Statement
- List of applicable FCC rules
This device complies with FCC part 15C: 15.247&15.407 - Summarize the specific operational use conditions
This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. And the module should be installed at a minimum distance of 20 cm away from a person nearby. The host product manufacturer should state this information to the host instruction manual. - Trace antenna designs
Not applicable. - RF exposure considerations
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This modular must be installed and operated with a minimum distance of 20 cm between the radiator and user body. - Antennas
Antenna Type: PCB Antenna
Antenna Gain:
2.4G BT：2.5 dBi
2.4G WIFI：3.05 dBi
5.2G WIFI：4.39 dBi
5.3G WIFI：4.68 dBi
5.6G WIFI：5.57 dBi
5.8G WIFI：5.68 dBi
The antenna is permanently attached and not considered of replacement. - Label and compliance information
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.
Caution: The user is cautioned that 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.
If the FCC identification number 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: 2AQ5RWBL-8822BU1-A Or Contains FCC ID: 2AQ5RWBL-8822BU1-A”.
Information on test modes and additional testing requirements
Any final host product with the modular transmitter installed should be under test according to the guidance given in KDB 996369 D04. To enter test mode for the module, REALTEK 11ac 8822 BU USB WLAN NIC Mass production kit software and command are necessary. When
something wrong happens in configuring test modes for the host products with modules, the host product manufacturer should coordinate with the module manufacturer for technical support. It is recommended that some investigative measurements should be taken to confirm that the host product with the module installed does not exceed the spurious emissions limits or band edge limits.
Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247&15.407) listed on the grant, and 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.
Canada Statement
This device complies with Industry Canada’s license-exempt RSS. Operation is subject to the following two conditions:
- This device may not cause interference; and
- This device must accept any interference, including interference that may cause undesired operation of the device.
The device meets the exemption from the routine evaluation limits in section 2.5 of RSS 102 and compliance with RSS-102 RF exposure, users can obtain Canadian information on RF exposure and compliance.
The device for operation in the band 5150-5250 MHz is only for indoor use to reduce the potential for harmful interference to co-channel mobile satellite systems
