WIFI-2-R812USA2
Dual Band 11ac USB WiFi Module with RTL8812AU
1. Introduction
WIFI-2-R812USA2 is based on realtek RTL8812AU, is a WLAN 11ac Dual Band module, which fully
supports the features and functional compliance of IEEE 802.11 a/b/g/n/ac standards. 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 Realtek RTL8812AU. It is a highly integrated single-chip MIMO(Multiple In Multiple Out) Wireless
LAN (WLAN) USB2.0 network interface controller complying with the 802.11ac specification. It
combines a MAC, a 2T2R capable baseband, and RF in a single chip. The RTL8812AU provides a
complete solution for a high throughput performance wireless client.

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, includ
ing interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authori
ty 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 pa
rt 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a re
sidential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and u
sed in accordance with the instructions, may cause harmful interference to radio communications. However, there is n
o guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interferenc
e to radio or television reception, which can be determined by turning the equipment off and on, the user is encourage
d to try to correct the interference by one or more of the following measures:
‐ Reorient or relocate the receiving antenna.
‐ Reorient or relocate the receiving antenna.
‐ Reorient or relocate the receiving antenna.
‐Consult the dealer or an experienced radio/TV technician for help important announcement
Important Note:
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment
should be installed and operated with minimum distance 20cm between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Country Code selection feature to be disabled for products marketed to the US/Canada.
This device is intended only for OEM integrators under the following conditions:
1. The antenna must be installed such that 20 cm is maintained between the antenna and users, and
2. The transmitter module may not be co-located with any other transmitter or antenna,
Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another
transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final
product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including
the transmitter) and obtaining a separate FCC authorization.
Any company of the host device which install this modular with limit modular approval should perform the test of
radiated emission and spurious emission according to FCC part 15C:15.247 and 15.209 requirement, Only if the test
result comply with FCC part 15.247 and 15.209 requirement, then the host can be sold legally.
End Product Labeling
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: 2AFG6-R812USA2.
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this
RF module in the user’s manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.
When the module is installed inside another device, the user manual of this device must contain below warning
statements;
1. 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.
(2) This device must accept any interference received, including interference that may cause undesired
operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment. The devices must be installed and used in strict accordance with the
manufacturer's instructions as described in the user documentation that comes with the product.
Custom design antennas may be used, however the OEM installer must following the FCC 15.21
requirements and verify if new FCC approval will be necessary.
