1. Introduction
AzureWave Technologies, Inc. introduces IEEE 802.11b/g/n USB wireless module, AW-NU240. This
USB wireless module is a highly integrated wireless local area network (WLAN) solution to let users enjoy
the digital content through the latest wireless technology without using the extra cables and cords. It
enables a high performance, cost effective, low power, compact solution that easily fits onto one side of a
USB.
Compliant with the IEEE 802.11b/g/n standard, the AW-NU240 uses Direct Sequence Spread Spectrum
(DSSS), Orthogonal Frequency Division Multiplexing (OFDM), BPSK, QPSK, 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 system power requirements by using
AW-NU240.
Longer Range and Faster Speed
Comparing to 802.11g technology, 802.11n standard make big improvement on speed and range. It
Increases wireless range by up to 2 times and reduces dead spots in coverage area. The robust signal
travels farther, maintaining wireless connections more farther than standard 802.11g. The data rate can
up to 150Mbps data rate.

FCC Statement:
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.
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

LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following "
Contains TX FCC ID: MDZAZW9271-240 ". If the size of the end product is larger
than 8x10cm, then the following FCC part 15.19 statement has to also be available
on the label: This device complies with Part 15 of 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.
