. Overview
A zurewave AW-NU137 USB 2.0 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 extra cables and cords. It provides easy-to-use, high performance, cost
effective and low power solution. Moreover, AW-NU137 enables compatible high-speed wireless
connectivity within home, business and public access wireless networks.
Compliant with the IEEE 802.11n/g/b standard, AW-NU137 uses Direct Sequence Spread Spectrum
(DSSS), Orthogonal Frequency Division Multiplexing (OFDM), BPSK, QPSK, CCK and QAM
baseband modulation technologies. When you are usingAW-NU137, 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-NU137 802.11n/g/b Wireless USB Module provides up to 128-bit level of WEP security to
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-NU137 got
great improvements on speed and range. AW-NU137 is able to double the data rate up to 150Mbps.

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.
