7. Reference Design
Power supply requirements
It is recommended to supply the module with power higher than 150mA (12V) to ensure
enough power supply to the module and avoid power down during data transmission.
13www.ibroadlink.com
8.2 Minimizing Radio Interference
The following precautions should be considered during designing when using PCB antenna:
1. Do not place any electrical components in antenna area on main board and it’s better to
leave this area blank on PCB.
2. It is recommended to not place any electrical components within 10mm range of module
antenna and not design any circuit or bond copper on main board under this area.
3. Do not use the module inside any metal case or containers with metal painting.
Keep the antenna of wifi module next to the edge of main board during design of PCB to
ensure better performance of antenna.

Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the
equipment.
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.
MPE Requirements
To satisfy FCC / IC RF exposure requirements, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during device operation.
To ensure compliance, operations at closer than this distance is not recommended.
Les antennes installées doivent être situées de facon à ce que la population ne puisse
y être exposée à une distance de moin de 20 cm. Installer les antennes de facon à ce
que le personnel ne puisse approcher à 20 cm ou moins de la position centrale de l’
antenne.
