WIFI-2-R811USA2 Dual Band 11ac USB WiFi Module with RTL8811AU 四川长虹电子部品有限公司 Sichuan Changhong Electronic Component Co., Ltd. page 4 of 9 1. Introduction WIFI-2-R811USA2 is based on realtek RTL8811AU, is a WLAN 11ac 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 RTL8811AU. It is a highly integrated single-chip SISO(Single In Single Out) Wireless LAN (WLAN) USB2.0 network interface controller complying with the 802.11ac specification. It combines a MAC, a 1T1R capable baseband, and RF in a single chip. The RTL8811AU provides a complete solution for a high throughput performance wireless client. Figure 1 Module Block Diagram 1.2 Specification reference This specification is based on additional references listed below. _ IEEE Std. 802.11a _ IEEE Std. 802.11b _ IEEE Std. 802.11g _ IEEE Std. 802.11n _ IEEE Std. 802.11ac 1.3 System Functions Table1: General Specification as below: Main Chipset Realtek RTL8811AU-VS Operating Frequency 2.412~2.472GHz & 5.180 -5.240 GHz& 5.745 -5.825 GHz Wi-Fi Standard 802.11a/b/g/n/ac (1x1) Modulation WIFI: 11b: DBPSK, DQPSK and CCK and DSSS 11a/g: BPSK, QPSK, 16QAM, 64QAM and OFDM 11n: BPSK, QPSK, 16QAM, 64QAM and OFDM 11ac: BPSK, QPSK, 16QAM, 64QAM, 256QAM and OFDM 2.412~2.462GHz & 5.180 -5.240 GH z& 5.745 -5.825 GHz

FCC StatementThis device complies with Part 15 of the FCC rules. Operation is subject to the following twoconditions: 1) this device may not cause harmful interference, and 2) this device must acceptany interference received, including interference that may cause undesired operation.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 reasonableprotection against harmful interference in a residential installation. This equipment generatesuses and can radiate radio frequency energy and, if not installed and used in accordance withthe instructions, may cause harmful interference to radio communications. However, there is noguarantee that interference will not occur in particular installation. If this equipment does causeharmful interference to radio or television reception, which can be determined by turning theequipment off and on, the user is encouraged to try to correct the interference by one or moreof 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 isconnected.--Consult the dealer or an experienced radio/TV technician for help.Changes or modifications not expressly approved by the party responsible for compliance couldvoid the user’s authority to operate the equipment.FCC Radiation Exposure Statement The modular can be installed or integrated in mobile or fix devices only. This modular cannot beinstalled in any portable device, for example, USB dongle like transmitters is forbidden. Thismodular complies with FCC RF radiation exposure limits set forth for an uncontrolledenvironment. This transmitter must not be co-located or operating in conjunction with any otherantenna or transmitter. This modular must be installed and operated with a minimum distance of20 cm between the radiator and user body.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 labelreferring to the enclosed module. This exterior label can use wording such as the following:“Contains Transmitter Module FCC ID: 2AC49-R811USA2.When the module is installed inside another device, the user manual of this device must containbelow warning statements; 1. This device complies with Part 15 of the FCC Rules. Operation issubject 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 causeundesired operation. 2. Changes or modifications not expressly approved by the partyresponsible for compliance could void the user's authority to operate the equipment. The devicesmust be installed and used in strict accordance with the manufacturer's instructions as describedin the user documentation that comes with the product.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 and 15E : 15.247 , 15.209 and 15.407 requirement, Only if the test result comply with FCC part 15C and 15E: 15.247 ， 15.209 ，15.407 requirement，then the host can be sold legally.
