Wireless 802.11 a/b/g/n Module
Chapter 1: Product Overview
AzureWave Technologies, Inc. introduces the advanced IEEE 802.11a/b/g/n
2x2 dual-band WLAN USB 2.0 module - AW-NU231. The module
supports both 2.4GHz and 5GHz bands and Multiple Input Multiple Output (MIMO)
technology. With MIMO, information is simultaneously sent and received over two
antennas in the same frequency band, thus providing greater range and
increased throughput while maintaining compatibility with legacy IEEE
802.11a/b/g devices. By using AW-NU231, the customers can easily enable the
development of USB 2.0-based Draft-802.11n WLAN client and router subsystem
solutions for all WLAN markets that can take advantage of the high throughput
and extended range of MIMO.
In Compliance with the IEEE 802.11a/b/g/n standard, the AW-NU231 uses Direct
Sequence Spread Spectrum (DSSS), orthogonal frequency division multiplexing
(OFDM), DBPSK, DQPSK, CCK and QAM baseband modulation technologies. A
high level of integration and full implementation of the power management
functions specified in the IEEE 802.11 standard minimize the system power
requirements. By using AW-NU231, state-of-the-art security is provided by
industry standard system support for WPA, WPA2, and hardware accelerated
AES encryption/decryption coupled with TKIP and IEEE 802.1X support.
Embedded hardware acceleration enhances system performance and
significantly reduces host-CPU utilization in both client and access point
configurations. The AW-NU231 also supports Broadcom’s widely accepted and
deployed SecureEasySetup™ (SES) application for ease-of-use wireless
secured networks.
The AW-NU231 module adopts Broadcom’s latest Draft-802.11n-based chip,
BCM4323, innovations designed to increase WLAN system performance and
extend range using MIMO technology. The module integrates two dual-band
antennas which are used for 2x2 MIMO and supports 2-stream spatial
multiplexing up to 300Mbps.

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.
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.
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.
For operation within 5.15 ~ 5.25GHz frequency range, it is restricted to indoor
environment.
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.
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

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 integrator is still responsible for testing their end-product for any
additional compliance requirements required with this module installed.
IMPORTANT NOTE: In the event that these conditions can not 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 can not 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.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be
installed such that 20 cm may be maintained between the antenna and users. The final
end product must be labeled in a visible area with the following: “Contains FCC ID:
