AW-NU173
IEEE 802.11 b/g/n WLAN Wireless Module
User’s Manual
I. Introduction
AzureWave Technologies, Inc. introduces the first IEEE 802.11b/g/n WLAN module Card
-AW-NU173. By using AW-NU173, the customers can easily enable the Wi-Fi embedded
applications with the benefits of high design flexibility, short development cycle, and quick
time-to-market.
Compliance with the IEEE 802.11b/g/n standard, the AW-NU173 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-NU173. In addition to the support of WPA/WPA2 and WEP
64-bit and 128-bit encryption, the AW-NU173 also supports the IEEE 802.11i security standard
through the implementation of Advanced Encryption Standard (AES)/Counter Mode CBC-MAC
Protocol (CCMP), Wired Equivalent Privacy (WEP) with Temporal Key Integrity Protocol (TKIP),
Advanced Encryption Standard (AES)/Cipher-Based Message Authentication Code (CMAC), and
WLAN Authentication and Privacy Infrastructure (WAPI) security mechanisms.
For the video, voice and multimedia applications the AW-NU173 support 802.11e Quality of
Service (QoS).
The AW-NU173 supports USB for WLAN to the host processor.
ii. Features
USB interfaces support for WLAN Multiple power saving modes for low power consumption IEEE 802.11i for advanced security Quality of Service (QoS) support for multimedia applications
iii. Product Review
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.
