User’s Manual

I. Introduction

i. Overview

AzureWave IEEE 802.11b/g WLAN module, ---AW-GM320 is targeted to mobile devices including, Digital Still
Cameras (DSCs), Portable Media Players (PMPs), and Gaming Devices, Notebook which need small footprint
package, low power consumption, multiple interfaces and OS support. By using AW-GM320, 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 standard, the AW-GM320 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-GM320. In addition to the
support of WPA/WPA2 and WEP 64-bit and 128-bit encryption, the AW-GM320 also supports the IEEE 802.11i
security standard through the implementation of Advanced Encryption Standard (AES)/Counter Mode CBC-MAC
Protocol (CCMP), and WEP with TKIP security mechanisms. The AW-GM320also supports IPSec with
DES/3DES/ASE encryption and MD5/SHA-1 authentication. For the video, voice and multimedia applications, the
AW-GM320 supports 802.11e Quality of Service (QoS). The AW-GM320 supports SDIO and G-SPI for WLAN to
the host processor.

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.

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.
