The Realtek is a highly integrated single-chip for 802.11n Wireless LAN and Bluetooth 2.1/3.0/4.0.It was
composed of MAC, baseband, and RF, providing a complete solution for a high-performance integrated
WLAN and BT. There are two kind of interface operation: one is SDIO for WLAN and UART for BT. The
other one is USB for both WLAN and BT.(USB multi-function)
The integration provides better coordination between 802.11 and Bluetooth, and with sophisticated
dynamic power control and packet traffic arbitration, is able to provide the best coexistence performance.
also integrates RF/PA/LNA for both of 802.11n and Bluetooth, so the external part numbers is reduced to
minimum.
The 802.11 part supports 150Mbps PHY rate and delivers reliable throughput from an extended distance.
The Bluetooth part supports latest 3.0+HS/4.0+LE operation and provides smooth user experience under all
usage scenarios. Optimized RF architecture and baseband algorithms provide superb performance and
lowest power consumption.

4.5.1 Federal Communication Commission Interference Statement
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 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.
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.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE:
FCC 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 & your
body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels 1 through
11.
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,
3) For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band by supplied
firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain
change.
As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM
