I. Introduction
iiii. Overview
. Overview
. Overview. Overview
A
zurewave
network (WLAN) solution to let users enjoy the digital content through the latest wireless
technology without using extra cables and cords. It provides easy-to-use, high performance, cost
effective and low power solution. Moreover, AW-NU203 enables compatible high-speed wireless
connectivity within home, business and public access wireless networks.
Compliant with the IEEE 802.11n/g/b standard, AW-NU203 uses Direct Sequence Spread Spectrum
(DSSS), Orthogonal Frequency Division Multiplexing (OFDM), BPSK, QPSK, CCK and QAM
baseband modulation technologies. When you are using AW-NU203, a high level of integration and
full implementation of the power management functions specified in the IEEE 802.11 standard can
minimize system power requirements.
The AW-NU203 802.11n/g/b Wireless USB Module provides up to 128-bit level of WEP security to
AW-NU203
USB 2.0 Wireless Module is a highly integrated wireless local area
your wireless data transfers. It is able to run in the operating systems of Windows XP/Vista in either
Infrastructure mode or Ad-Hoc mode. Comparing to previous wireless technology, AW-NU203 got
great improvements on speed and range. The wireless range increased up to two times wider and
coverage area reduced the situation of dead spots. “Multiple In, Multiple Out” (MIMO) technology
uses signal reflections to increase the range and maintain wireless connections up to five times
farther; therefore, with MIMO, AW-NU203 is able to double the data rate up to 300Mbps.

1. Connection Mode
◎Infrastructure Mode
Infrastructure mode needs an access point to establish the network, which can provide wireless accesses
within valid range for users to communicate with others or transmit data with a wired network. There are
several benefits of Infrastructure networking:
√ Roaming: a wireless LAN enabled computer can physically move from the operating range of one
access point to the other without losing connection. There is a quick association made between new
access point and wireless device as the computer traverses from the coverage of one access point to
another.
√ Range Extension: each wireless LAN enabled computer within the range of access point can
communicate with other wireless LAN enabled computers within the effective range from the access
point.
√ Wired to wireless LAN connection: the access point will establish a bridge between wireless LAN
and other wired counterparts.
Infrastructure Mode
◎Ad-hoc Mode
The difference between Ad-hoc mode and Infrastructure mode is that Ad-hoc mode does not need the
access point or router. When you use this mode, your computer will act as a server within the valid range
and connect directly to others in the same LAN workgroup.
Ad-hoc Mode
It is recommended to choose this mode when there is no access point showed on your wireless
network.
II. Installation
