Wireless 802.11 a/b/g/n dongle

Chapter 1: Product Overview

AzureWave Technologies, Inc. introduces the advanced IEEE 802.11a/b/g/n
2x2 dual-band WLAN USB 2.0 dongle - AW-NU231-D. The dongle 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-D, 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-D 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-D, 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-D also supports Broadcom's widely accepted and
deployed SecureEasySetup™ (SES) application for ease-of-use wireless
secured networks.
The AW-NU231-D dongle 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.
