Wireless 802.11 a/b/g/n Module

Chapter 1: Product Overview

AzureWave Technologies, Inc. introduces the advanced IEEE 802.11a/b/g/n

2x2 dual-band WLAN USB 2.0 module - AW-NU231. The module

supports both 2.4GHz and 5GHz bands and Multiple Input Multiple Output (MIMO)

technology. With MIMO, information is simultaneously sent and received over two

antennas in the same frequency band, thus providing greater range and

increased throughput while maintaining compatibility with legacy IEEE

802.11a/b/g devices. By using AW-NU231, the customers can easily enable the

development of USB 2.0-based Draft-802.11n WLAN client and router subsystem

solutions for all WLAN markets that can take advantage of the high throughput

and extended range of MIMO.

In Compliance with the IEEE 802.11a/b/g/n standard, the AW-NU231 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-NU231, state-of-the-art security is provided by

industry standard system support for WPA, WPA2, and hardware accelerated

AES encryption/decryption coupled with TKIP and IEEE 802.1X support.

Embedded hardware acceleration enhances system performance and

significantly reduces host-CPU utilization in both client and access point

configurations. The AW-NU231 also supports Broadcom’s widely accepted and

deployed SecureEasySetup™ (SES) application for ease-of-use wireless

secured networks.

The AW-NU231 module adopts Broadcom’s latest Draft-802.11n-based chip,

BCM4323, innovations designed to increase WLAN system performance and

extend range using MIMO technology. The module integrates two dual-band

antennas which are used for 2x2 MIMO and supports 2-stream spatial

multiplexing up to 300Mbps.
