1-1. Product Overview and Functional Description
AzureWave Technologies, Inc. introduces the first IEEE 802.11b/g/n WLAN, Bluetooth and FM combo
module - AW-NH931. The module is targeted to mobile devices including, Digital Still Cameras (DSCs),
Portable Media Players (PMPs), and Gaming Devices, mobile phones which need small footprint
package, low power consumption, multiple OS support. By using AW-NH931, the customers can easily
enable the Wi-Fi, BT and FM 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-NH931 uses DSSS, 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-NH931. In addition to the support of WPA/WPA2 (personal) and WEP
encryption, the AW-NH931 also supports the IEEE 802.11i security standard through AES and TKIP
acceleration hardware for faster data encryption. The AW-NH931 is also Cisco Compatible Extension
(CCX) certified. For the video, voice and multimedia applications the AW-NH931 support 802.11e
Quality of Service (QoS).
For Bluetooth operation, the AW-NH931 is Bluetooth 2.1+Enhanced Data Rate (EDR) compliant. The
AW-NH931 supports extended Synchronous Connections (eSCO), for enhanced voice quality by
allowing for retransmission of dropped packets, and Adaptive Frequency Hopping (AFH) for reducing
radio frequency interference. It provides easier to connect devices, lower power consumption and
improved security.
For FM receiver/transmitter, the AW-NH931 is 76-MHz to 108-MHz FM bands supported and supports
the European Radio Data Systems (RDS) and the North American Radio Broadcast Data System
(RBDS) modulations.
The AW-NH931 supports standard interface SDIO v1.2
(4-bit and 1-bit) for WLAN, High-speed UART
interface for BT/FM host controller interface, and PCM for BT audio data. The demodulated FM audio
signal is available as line-level analog stereo output. AW-NH931 is suitable for multiple mobile
processors for different applications. With the combo functions and the good performance, the AW-
NH931 is the best solution for the consumer electronics and the laptops.
